BACKGROUND OF THE INVENTION

The present invention relates to personal care products, such as wipes and absorbent articles, that are capable of providing a skin health benefit to the user. More particularly, the present invention relates to wet wipes comprising at least one botanical compound that selectively controls the growth and/or adherence of flora on the skin. The botanical compounds described herein and suitable for incorporation into a wipe or absorbent article may selectively promote the adherence of healthy flora to the surface of skin or mucosa, selectively inhibit the growth of problem flora on or around the skin surface, selectively inhibit the adherence of problem flora to the surface of skin or mucosa, or provide multiple combinations of these effects.

A variety of flora, both beneficial and pathogenic, may be found on the skin at any given time. Problem flora, such as pathogenic bacteria and yeast, have been associated with numerous ailments, including skin infections, diaper rash, urinary or vaginal infections, and malodors, and are associated with various irritants, such as proteases, lipases, carbohydrases, lipopolysaccharides (“LPS”), volatile organic compounds (“VOCs”), and other bio-molecules. In contrast, healthy bacteria attach to the skin, and may provide a variety of benefits, including playing a role in preventing pathogenic organisms from colonizing or growing.

The disruption in the protection of healthy flora may result in the colonization of other organisms, which in turn may cause irritation, infection, and diseases on or near the skin surface. One example of a healthy bacterium is Lactobacillus acidophilius, which colonizes the vaginal epithelium during child-bearing years, and inhibits the growth of pathogens. Another skin bacterium which can have positive health attributes is Staphylococcus epidermidis. S. epidermidis is a normal microbial inhabitant of human skin. In most cases, strains of S. epidermidis are nonpathogenic and play a protective role in their host. For instance, S. epidermidis appears to prevent colonization of the skin by dermatophytic fungi, and may alter the production of irritating metabolites. In limited circumstances, S. epidermidis, however, can become an opportunistic pathogen by spreading into the blood through breaks in skin barriers. Individuals most susceptible to S. epidermidis infection are intravenous drug users, newborns, elderly, and those using catheters or other artificial appliances. Regardless, S. epidermidis is generallly regarded as a bacteria that provides a health benefit.

In contrast, an example of a common pathogenic flora is Candida albicans. When in yeast form, C. albicans naturally inhabits the human digestive tract, and is a normal part of bowel flora. However, under certain conditions, such as a weakened immune system, a high sugar diet, or improper pH in the digestive system, among others, C. albicans may shift from the yeast stage, to an invasive mycelial fungal form. The mycelial fungal form of C. albicans binds readily to the skin and mucus membranes, and is associated with a wide variety of infections, including vaginal yeast infections, oral infections, and diaper rash.

Other common pathogenic flora include Pseudomonas aeruginosa, Proteus mirabilis, and Escherichia coli. Like C. albicans, E. coli naturally inhabit the human gastro-intestinal tract. However, E. coli can be pathogenic, and are responsible for several types of infections in humans, including urinary tract infections. For example, E. coli can colonize from the feces or perineal region, and ascend the urinary tract to the bladder, causing infection and irritation.

P. aeruginosa is an opportunistic pathogen of humans, and is resistant to many antibiotics. P. aeruginosa may infect almost any type of compromised tissue, and can cause a variety of infections, including urinary tract infections, respiratory system infections, dermatitis, soft tissue infections, and bacteremia, as well as a variety of systemic infections, particularly in immunosuppressed patients.

P. mirabilis is a Gram negativie rod that is widely distributed in nature and easily isolated in the feces of most animals, but is hardly ever found in high numbers unless the normal intestinal microflora is altered. P. mirabilis can cause invasive diarrhea and severe infections of the upper urinary tract, and has also been implicated in infections of blood and wounds.

To date, skin cleaning products, such as wet wipes and dry wipes, have primarily cleaned the skin by attempting to remove and/or kill all flora present on the skin, regardless of whether the flora are potentially beneficial or potentially harmful. For example, numerous commercially available wet wipes comprise at least one antimicrobial compound, such as an organic acid, which is typically used in combination with a surfactant to kill flora on the skin surface. Although typically effective in killing flora located on the skin surface, the antimicrobial wipe kills all flora and does not, and cannot, distinguish between “good” and “bad” flora.

Based on the foregoing, it would be desirable to provide a skin health benefit for inhibiting the growth or adherence to the skin of problem flora, while maintaining, or even enhancing the adherence of healthy flora. Products, such as wipes or absorbent articles, that comprise one or more compounds capable of selectively controlling the growth and/or adherence of flora to the skin would thus be desirable, and could impart a beneficial health effect to the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In accordance with the present invention, it has been discovered that certain bio-compounds, such as specific botanical extracts or botanical actives, can be utilized in combination with personal care products, such as wipes or absorbent articles, to impart a skin health benefit by selectively controlling the balance of flora on the skin. More specifically, it has been discovered that certain botanical compounds may provide at least one of the following benefits when used in combination with a wipe substrate or absorbent article and contacted with the skin or mucosa: (i) promote the adherence of healthy flora to the surface of skin or mucosa, (ii) inhibit the growth of problem flora on the skin surface, and/or (iii) inhibit the adherence of problem flora to the surface of skin or mucosa. By introducing a botanical compound, or a combination of botanical compounds having one or more of these characteristics into a solution that is used in combination with a wipe or absorbent article substrate, it is possible to selectively control the growth and adherence of various bacteria and yeast on the skin.

The personal care products of the present invention contain at least one botanical compound. As used herein, the term “botanical compound” is meant to include bio-compounds such as botanical extracts and/or botanical actives, as well as essential oils and herbs. The botanical compound is capable of improving the health of skin contacted by the wipe or absorbent article during normal use by selectively controlling the growth and/or adherence of flora to the skin. Numerous personal care products can be used in combination with the botanical compounds described herein in accordance with the present invention to impart a skin health benefit to the user. For example, one or more of the botanical compounds described herein can be used in combination with wipes, such as wet wipes, hand wipes, face wipes, cosmetic wipes, household wipes, dry wipes, feminine wipes, and the like, to selectively control the balance of flora on the skin by reducing the growth or adherence of problem flora, such as pathogenic bacteria or yeast, to the skin, and/or promoting the adherence of beneficial flora, such as healthy bacteria, to the surface of skin or mucosa.

In addition, one or more of the botanical compounds described herein can be used in combination with an absorbent article such as diapers, training pants, adult incontinence garments, feminine napkins, tampons, interlabial pads, facial tissue, wound management products, paper towels, and bath tissue. As will be understood by one skilled in the art, the botanical compound may be directly impregnated on the wipe or absorbent substrate, or may be in a liquid formulation or ointment used with the wipe or absorbent article.

Although discussed primarily in combination with a wipe substrate, it should be understood that the botanical compounds can also be used in combination with other nuerous absorbent products described above. Materials suitable for use as the substrate of the wipe are well known to those skilled in the art, and typically include a fibrous sheet material, which may be either woven or nonwoven. For example, the wipes incorporating the botanical compounds described herein to improve skin health may include nonwoven fibrous sheet materials, which include meltblown, coform, air-laid, bonded-carded web materials, hydroentangled materials, and combinations thereof. Such materials can be comprised of synthetic or natural fibers, or a combination thereof. Typically, wipes define a basis weight of from about 25 to about 120 grams per square meter and desirably from about 40 to about 90 grams per square meter.

In a particular embodiment, the wipes incorporating the botanical compounds described herein comprise a coform basesheet of polymeric microfibers and cellulosic fibers having a basis weight of from about 60 to about 80 grams per square meter and desirably about 75 grams per square meter. Such coform basesheets are manufactured generally as described in U.S. Pat. No. 4,100,324, which is incorporated by reference. Typically, such coform basesheets comprise a gas-formed matrix of thermoplastic polymeric meltblown microfibers, such as, for example, polypropylene microfibers, and cellulosic fibers, such as, for example, wood pulp fibers.

The relative percentages of the polymeric microfibers and cellulosic fibers in the coform basesheet can vary over a wide range depending upon the desired characteristics of the wet wipes. For example, the coform basesheet may comprise from about 20 to about 100 weight percent, desirably from about 20 to about 60 weight percent, and more desirably from about 30 to about 40 weight percent of the polymeric microfibers based on the dry weight of the coform basesheet being used to provide the wipes.

Alternatively, the wipes incorporating the botanical compounds described herein can comprise a composite, which includes multiple layers of materials such as those described in U.S. Pat. No. 6,028,018, which is incorporated by reference. For example, the wipes may include a three layer composite, which includes an elastomeric film or meltblown layer between two coform layers as described above. In such a configuration, the coform layers may define a basis weight of from about 15 to about 30 grams per square meter and the elastomeric layer may include a film material such as a polyethylene metallocene film.

As mentioned above, one type of wipe suitable for use in combination with the botanical compounds described herein to improve skin health include wet wipes, which, in addition to the wipe substrate, comprise a liquid solution or formulation. The liquid solution or formulation can be any liquid, which can be absorbed into the wet wipe basesheet and may include any suitable components, which provide the desired wiping properties. For example, the components may include water, emollients, surfactants, fragrances, preservatives, chelating agents, pH buffers, or combinations thereof as are well known to those skilled in the art. Further, the liquid may also contain lotions, medicaments, and/or antimicrobials.

The amount of liquid contained within each wet wipe may vary depending upon the type of material being used to provide the wet wipe, the type of liquid being used, the type of container being used to store the wet wipes, and the desired end use of the wet wipe. Generally, each wet wipe can contain from about 150 to about 600 weight percent and desirably from about 250 to about 450 weight percent liquid based on the dry weight of the wipe for improved wiping. In a particular aspect, the amount of liquid contained within the wet wipe is from about 300 to about 400 weight percent and desirably about 330 weight percent based on the dry weight of the wet wipe. If the amount of liquid is less than the above-identified ranges, the wet wipe may be too dry and may not adequately perform. If the amount of liquid is greater than the above-identified ranges, the wet wipe may be oversaturated and soggy and the liquid may pool in the bottom of the container.

Each wet wipe is generally rectangular in shape and may have any suitable unfolded width and length. For example, the wet wipe may have an unfolded length of from about 2.0 to about 80.0 centimeters and desirably from about 10.0 to about 25.0 centimeters and an unfolded width of from about 2.0 to about 80.0 centimeters and desirably from about 10.0 to about 25.0 centimeters. Typically, each individual wet wipe is arranged in a folded configuration and stacked one on top of the other to provide a stack of wet wipes. Such folded configurations are well known to those skilled in the art and include c-folded, z-folded, quarter-folded configurations and the like. The stack of folded wet wipes may be placed in the interior of a container, such as a plastic tub, to provide a package of wet wipes for eventual sale to the consumer. Alternatively, the wet wipes may include a continuous strip of material which has perforations between each wipe and which may be arranged in a stack or wound into a roll for dispensing.

In one embodiment of the present invention, one or more botanical compounds are introduced into or onto a fibrous wipe substrate, absorbent substrate, a solution or ointment for use with a wipe substrate or absorbent article. When the wipe or absorbent article contacts skin or mucosa, the botanical compound contacts the skin or mucosa, and may be actually transferred to the skin or mucosa, thereby selectively affecting the growth and/or adherence of flora to the portion of the skin or mucosa contacted by the wipe or absorbent article. In a specific embodiment, the botanical compound is introduced into the liquid formulation of a wet wipe. The botanical compound preferably promotes the adherence of at least one healthy flora to the surface of skin or mucosa, and/or inhibits the growth of at least one problem flora on or around the skin surface, and/or inhibits the adherence of at least one problem flora to the surface of skin or mucosa.

As noted above, beneficial flora are often naturally found on the skin or mucosal surfaces of the body, and may provide a variety of beneficial effects. It is thus often desirable to maintain or promote the adherence of such healthy flora to the surface of skin or mucosa to increase the benefit. Some examples of healthy flora include Lactobacillus acidophilus, some other Lactobacillus species, and Atopobium species, and to an extent, Staphlococcus epidermidis.

Unlike healthy flora, problem flora, such as pathogenic bacteria or yeast, as noted above, are associated with numerous ailments, including skin infections, diaper rash, urinary or vaginal infections, and malodors, among others. As such, it is often desirable to selectively inhibit the growth and/or adherence of these problem flora. Some examples of problem flora include Candida albicans, Proteus mirabilis, and Pseudomonas aeruginosa. It will be apparent to those skilled in the art that there are numerous other examples of both healthy and problem flora, other than those described herein, and that the growth and/or adherence of these flora may be controlled in a manner similar to that described herein.

Suitable botanical compounds for use in combination with the personal care products described herein include botanical compounds that have one or more of the following effects when contacted with the skin: (i) promote the adherence of Lactobacillus acidophilus to the surface of skin or mucosa; (ii) promote the adherence of Staphlococcus epidermidis to the surface of skin; (iii) inhibit the growth on or around the skin surface of at least one organism selected from the group consisting of Candida albicans, Proteus mirabilis, Pseudomonas aeruginosa, and Staphlococcus epidermidis; and (iv) inhibit the adherence to the surface of skin or mucosa of at least one organism selected from the group consisting of Candida albicans, Proteus mirabilis, Pseudomonas aeruginosa, and Staphlococcus epidermidis.

The protocols for testing the ability of botanical compounds to elicit any of these desired effects are set forth in the Examples. In general, the ability of a botanical compound to affect the adherence of an organism to skin is determined by comparing the adherence of the organism to skin in the presence of the botanical compound, to the adherence of the organism to skin in the absence of the botanical compound. If the amount of adherence in the presence of the botanical compound is 150% or greater than the amount of adherence in the absence of the botanical compound, then the botanical compound is an adherence promoter for that organism. If the amount of adherence in the presence of the botanical compound is 50% or less than the amount of adherence in the absence of the botanical compound, then the botanical compound is an anti-adherent for that organism.

Similarly, the ability of a compound to inhibit the growth of an organism (Examples 1 and 2) is determined relative to a control. As the following equations indicate, optical density of a sample containing a botanical compound and an organism and a control containing only the organism are measured at 0 and 18 hours:
[(OD650 sample @18 hours—OD650 sample @0 hours)/(OD650 yeast only @18 hours—OD650 yeast only @0 hours)]*100;
[(OD650 sample @18 hours—OD650 sample @0 hours)/(OD650 bacteria only @18 hours—OD650 bacteria only @0 hours)]*100.

For purposes of the present invention, a botanical compound is considered a growth inhibitor if the botanical compound has an IC50 value of 5% or less for the organism being tested, wherein IC50 is the concentration that inhibits the growth of the organism by 50%.

A variety of botanical compounds were tested using the protocols described herein with the results set forth in Tables 1 and 2. However, the ability of numerous other botanical compounds to affect the growth and/or adherence of healthy and/or problem flora to the surface of skin or mucosa, in addition to those tested herein, may also be determined using these protocols.

Some botanical compounds may have multiple beneficial effects. In addition, some botanical compounds may have one or more beneficial effect, as described above, as well as a less desired effect, such as inhibiting the adherence of Lactobacillus acidophilus to the surface of skin or mucosa. Such compounds may still be useful in combination with a wipe or absorbent article, of the present invention, depending on the type of wipe or absorbent article and the intended use of such product.

In one specific embodiment, a botanical compound which does not substantially promote the adherence of C. albicans, P. mirabilis, and P. aeruginosa is introduced into a solution for use in combination with a wipe substrate or absorbent article. In this embodiment, the botanical compound may increase the adherence of L. acidophilus or S. epidermidis, or may inhibit the growth and/or adherence to the surface of skin or mucosa of S. epidermidis, C. albicans, P. mirabilis, or P. aeruginosa. Suitable botanical compounds include Aloe Ferox HS, American Ginseng, Arkin Special, Bleuet MCF 783 Hydro, Calendula (Marigold), Ceramide Complex, Comfey leaves, Cromoist 0-25, Cromoist HYA, Dandelion, Devil's Claw, Dong Quai, Drago-Oat Active, Echinacea Dry Aq., Gingko Biloba, Ginseng GR 471 Hydro, Glucosamine 99, Goldenseal, Gotu Kola PG 5:1, Grape Seed, Grape Seed Extr., Green Tea, Green Tea Conc., Green Tea Extr., Green Tea HS, Hydrocotyle GR 040, Hydrolactin 2500, Hydrolite-5, Hydrosoy 2000 SF, Lamier Blanc MCF 796, Lavendar MCF 1484, Lime Blossom, Lime Blossom Distillate, Marigold (Calendula), Marron d'inde (horse chestnut), Marron d'inde MCF 1972, Milk Thistle, Nab Willowbark Extr., NSLE Lipomicron, Pineapple B, Sage Special, Sandal Complex, Soluble Wheat Protein, Spirulina, St. John's Wort W/S, White Mistle Toe, Witchhazel distillate, Witchhazel GW, Yucca 70, and. Yucca Extr. Powder 50%.

As previously discussed, L. acidophilus is a beneficial organism. As such, it is desirable to promote the adherence of L. acidophilus to the surface of skin or mucosa. Thus, in one embodiment, a botanical compound that is capable of increasing the adherence of L. acidophilus to the surface of skin or mucosa by at least about 50%, is incorportaed into or onto a product of the present invention. Suitable botanical compounds include Aloe Ferox HS, American Ginseng, Calendula (Marigold), Ceramide Complex, Comfey Leaves, Cromoist 0-25, Cromoist HYA, Dandelion, Devil's Claw, Dong Quai, Drago-Oat Active, Echinacea Dry Aq., Gingko Biloba, Ginseng GR 471 Hydro, Glucosamine 99, Goldenseal, Gotu Kola PG 5:1, Grape Seed, Green Tea, Hydrolite-5, Hydrosoy 2000 SF, Marron D'Inde (Horse Chestnut), Milk Thistle, Nab Willowbark Extr., Soluble Wheat Protein, Spirulina, St. John's Wort W/S, White Mistle Toe, Witchhazel Distillate, Witchhazel GW, Yucca 70, and Yucca Extr. Powder 50%. More specifically, the botanical compound is capable of increasing the adherence of L. acidophilus to the surface of skin or mucosa by at least about 1000%. Suitable botanical compounds include Calendula (Marigold), Ceramide Complex, Echinacea Dry Aq., Grape Seed, Spirulina, Witchhazel GW, and Yucca 70. Additionally, a suitable botanical compound that is capable of increasing the adherence of L. acidophilus to the surface of skin or mucosa is selected from the group consisting of Aloe Ferox HS, American Ginseng, Calendula (Marigold), Ceramide Complex, Comfey Leaves, Cromoist 0-25, Cromoist HYA, Dandelion, Devil's Claw, Dong Quai, Drago-Oat Active, Ginseng GR 471 Hydro, Glucosamine 99, Gotu Kola PG 5:1, Grape Seed, Hydrolite-5, Hydrosoy 2000 SF, Marron D'Inde (Horse Chestnut), Milk Thistle, Soluble Wheat Protein, Spirulina, Witchhazel Distillate, and Witchhazel GW.

The product comprising the botanical compound that promotes the adherence of L. acidophilius to the skin can be a feminine wipe, feminine napkin, tampon, or interlabial pad. A feminine wipe is a hygenic wipe that may be used to clean blood, menses and/or other body exudates from the skin and hair in the pudendal region of the body. As previously discussed, L. acidophilius colonizes the vaginal epithelium during child-bearing years, and inhibits the growth of some pathogens in the vaginal region. It would thus be particularly beneficial to introduce into or onto a feminine product one or more botanical compounds that promote the adherence of L. acidophilius to the surface of skin or mucosa. In contrast, botanical compounds such as Grape Seed Extract, Green Tea Conc., Lavendar MCF 1484, Lime Blossom, Lime Blossom Distillate, and Pineapple B inhibit the adherence of L. acidophilius to the surface of skin or mucosa, and would thus not be particularly beneficial for a feminine product, but may be suitable for use in combination with other types of wipes or absorbent articles, as described herein.

As previously indicated, in some instances it may be beneficial to promote the adherence of S. epidermidis to the surface of skin. Thus, a botanical compound that is capable of promoting the adherence of S. epidermidis to the surface of skin by at least about 50% can be used in combination with a product of the present invention. Suitable botanical compounds include Bleuet MCF 783 Hydro, Hydrocotyle GR 040, Hydrolactin 2500, Lavendar MCF 1484, Lime Blossom, Lime Blossom Distillate, Marigold (Calendula), and Sage Special.

As previously discussed, L. acidophilius is a beneficial flora, and, as such, it is advantageous not to inhibit the growth or adherence of L. acidophilius to the surface of skin or mucosa. Thus, in an even more specific embodiment of the above, the botanical compound is capable of increasing the adherence of S. epidermidis to the surface of skin by at least about 50%, and does not inhibit the growth of L. acidophilius on or around the skin surface, nor does it significantly inhibit the adherence of L. acidophilius to the surface of skin or mucosa. Such suitable botanical compounds include Bleuet MCF 783 Hydro, Hydrocotyle GR 040, Hydrolactin 2500, Marigold (Calendula), and Sage Special.

In addition to promoting the adherence of healthy flora, it may be beneficial to inhibit the adherence of problem flora to the surface of skin or mucosa. The products of the present invention may thus incorporate a botanical compound that inhibits the adherence of C. albicans, P. mirabilis, or P. aeruginosa to the surface of skin or mucosa. Thus, in one embodiment, the botanical compound is capable of inhibiting the adherence of C. albicans to the surface of skin or mucosa by at least about 50%. Suitable botanical compounds include Aloe Ferox HS, American Ginseng, Arkin Special, Comfey Leaves, Dong Quai, Echinacea Dry Aq., Glucosamine 99, Goldenseal, Grape Seed, Grape Seed Extr., Green Tea, Green Tea Conc., Green Tea Extr., Green Tea HS, Hydrolite-5, Lavendar MCF 1484, Marron D'Inde MCF 1972, Marron D'Inde (Horse Chestnut), Pineapple B, Sandal Complex, Soluble Wheat Protein, Yucca 70, and Yucca Extr. Powder 50%. More specifically, the botanical compound is capable of inhibiting the adherence of C. albicans to the surface of skin or mucosa by at least about 70%. Suitable botanical compounds include Aloe Ferox HS, Comfey Leaves, Glucosamine 99, Grape Seed, Green Tea, Green Tea Extr., Hydrolite-5, Pineapple B, Sandal Complex, Yucca 70, and Yucca Extr. Powder 50%. The botanical compound capable of inhibiting the adherence of C. albicans may also be selected from the group consisting of Aloe Ferox HS, American Ginseng, Comfey Leaves, Dong Quai, Glucosamine 99, Grape Seed, Green Tea Conc., Hydrolite-5, Lavendar MCF 1484, Marron D'Inde MCF 1972, Marron D'Inde (Horse Chestnut), Pineapple B, Sandal Complex, and Soluble Wheat Protein.

In another specific embodiment, the botanical compound is capable of inhibiting the adherence of P. mirabilis to the surface of skin or mucosa by at least about 50%. Suitable botanical compounds include Aloe Ferox HS, Cromoist HYA, Echinacea Dry Aq., Gingko Biloba, Grape Seed Extr., Green Tea, Green Tea Extr., Green Tea HS, Hydrolactin 2500, Hydrolite-5, Hydrosoy 2000 SF, Marron D'Inde (Horse Chestnut), Marron D'Inde MCF 1972, NSLE Lipomicron, Pineapple B, Sandal Complex, Witchhazel GW, Yucca 70, and Yucca Exr. Powder 50%. More specifically, the botanical compound is capable of inhibiting the adherence of P. mirabilis to the surface of skin or mucosa by at least about 70%. Suitable botanical compounds include Aloe Ferox HS, Echinacea Dry Aq., Gingko Biloba, Grape Seed Extr., Green Tea, Green Tea Extr., Hydrolactin 2500, Hydrolite-5, Marron D'Inde (Horse Chestnut), NSLE Lipomicron, Pineapple B, Sandal Complex, Witchhazel GW, Yucca 70, and Yucca Extr. Powder 50%. Even more specifically, the botanical compound capable of inhibiting the adherence of P. mirabilis is selected from the group consisting of Aloe Ferox HS, Hydrolactin 2500, Hydrolite-5, Marron D'Inde (Horse Chestnut), Pineapple B, Sandal Complex, and Witchhazel GW.

In another specific embodiment, the botanical compound is capable of inhibiting the adherence of Pseudomonas aeruginosa to the surface of skin or mucosa by at least about 50%. Suitable botanical compounds include Ceramide Complex, Echinacea Dry Aq., Grape Seed Extr., Green Tea, Green Tea Extr., Hydrolite-5, Nab Willowbark Extr., NSLE Lipomicron, Pineapple B, Sandal Complex, Soluble Wheat Protein, Yucca 70, and Yucca Extr. Powder 50%. More specifically, the botanical compound capable of inhibiting the adherence of Pseudomonas aeruginosa is selected from the group consisting of Ceramide Complex, Hydrolite-5, NSLE Lipomicron, Pineapple B, Sandal Complex, and Soluble Wheat Protein.

Since, as previously discussed, S. epidermidis can become an opportunistic pathogen, especially when exposed to breaks in the skin barrier, it would be advantageous to inhibit the adherence of S. epidermidis to the surface of skin, or to inhibit the growth of S. epidermidis on or around the skin surface when treating wounds. Thus, it would be particularly beneficial to introduce into or onto a wipe used for wound care or other wound management products a botanical compound that inhibits the adherence of Staphlococcus epidermidis to the surface of skin and/or inhibits the growth of S. epidermidis on or around the skin surface.

The products of the present invention may thus incorporate a botanical compound that inhibits the adherence of S. epidermidis to the surface of skin. In one embodiment, the botanical compound is capable of inhibiting the adherence of Staphlococcus epidermidis to the surface of skin by at least about 50%. Suitable botanical compounds include Aloe Ferox HS, Arkin Special, Comfey Leaves, Cromoist HYA, Devil's Claw, Echinacea Dry Aq., Gingko Biloba, Goldenseal, Gotu Kola PG 5:1, Grape Seed Extr., Green Tea, Hydrosoy 2000 SF, Marron D'Inde (Horse Chestnut), Marron D'Inde MCF 1972, Pineapple B, Soluble Wheat Protein, St. John's Wort W/S, White Mistle Toe, and Yucca 70. More specifically, the botanical compound that is capable of inhibiting the adherence of Staphlococcus epidermidis is selected from the group consisting of Aloe Ferox HS, Comfey Leaves, Cromoist HYA, Devil's Claw, Gotu Kola PG 5:1, Hydrosoy 2000 SF, Marron D'Inde (Horse Chestnut), Marron D'Inde MCF 1972, Pineapple B, and Soluble Wheat Protein.

In another embodiment, the botanical compound is capable of inhibiting the growth of Staphlococcus epidermidis on or around the skin surface. Suitable botanical compounds include compounds that have an IC50 value of about 5% or less for S. epidermidis, including Aloe, Ferox HS, Goldenseal, Grape Seed Extr., Green Tea, and Pineapple B. More specifically, the botanical compound that is capable of inhibiting the growth of Staphlococcus epidermidis is selected from the group consisting of Aloe Ferox HS and Pineapple B.

As previously discussed, it may be beneficial to inhibit the growth of other problem flora on or around the skin surface. The products of the present invention may thus incorporate a botanical compound that inhibits the growth of C. albicans, P. mirabilis, or P. aeruginosa on or around the skin surface. Thus, in one specific embodiment, the botanical compound is capable of inhibiting the growth of Candida albicans on or around the skin surface. Suitable botanical compounds include compounds that have an IC50 value of about 5% or less for C. albicans, and include Echinacea Dry Aq., Glucosamine 99, Goldenseal, Grape Seed Extr., Green Tea, Green Tea Conc., and Green Tea Extr. More specifically, the botanical compound that is capable of inhibiting the growth of Candida albicans is selected from the group consisting of of Glucosamine 99 and Green Tea Conc.

The wipe comprises a fibrous wipe substrate, a liquid formulation, and a botanical compound capable of increasing the adherence of Lactobacillus acidophilus to the surface of skin or mucosa by at least about 50%, wherein the liquid formulation is selected from the group consisting of a solution, a suspension, and an emulsion.

In addition to wipes and absorbent articles, the present invention is also directed to a method for selectively controlling the balance of flora on the skin. The method includes contacting a fibrous wipe substrate or absorbent substrate with the skin surface. The substrate includes a botanical compound for selectively controlling the growth and/or adherence of flora to the skin, wherein the compound promotes the adherence of at least one healthy flora to the surface of skin or mucosa, inhibits the growth of at least one problem flora on or around the skin surface, or inhibits the adherence of at least one problem flora to the surface of skin or mucosa, or any combination thereof. Additionally, a suitable method includes contacting a fibrous wipe substrate or absorbent substrate with the skin surface, wherein the substrate includes two or more botanical compounds for selectively controlling the growth and/or attachment of flora to the skin, wherein each compound promotes the adherence of at least one healthy flora to the surface of skin or mucosa, inhibits the growth of at least one problem flora on or around skin surface, or inhibits the adherence of at least one problem flora to the surface of skin or mucosa, or any combination thereof.

A more specific method involves promoting the adherence of Lactobacillus acidophilus to the surface of skin or mucosa. This method includes contacting a fibrous wipe substrate or absorbent substrate with the surface of skin or mucosa, wherein the substrate includes a botanical compound that is capable of increasing the adherence of Lactobacillus acidophilus to the surface of skin or mucosa by at least about 50%.

When present on a dry substrate, the botanical compound that selectively controls the balance of flora on skin is present in an amount of from about 0.01% (by weight of the treated substrate or product) to about 50% (by weight of the treated substrate or product), preferably from about 0.01% (by weight of the treated substrate or product) to about 10% (by weight of the treated substrate or product). When present as part of the liquid formulation used in combination with a wet wipe or absorbent article, the botanical compound is present in an amount of from about 0.01% (by total weight of the liquid formulation) to about 50% (by total weight of the liquid formulation), more preferably from about 0.01% (by total weight of the liquid formulation) to about 10% (by total weight of the liquid formulation).

Liquid formulations comprising botanical compounds, described herein, suitable for use in combination with a wipe or absorbent substrate can be solutions, suspensions, or emulsions. Many of the botanical compounds are substantially water-soluble or can be easily solubilized in water using techniques known to one skilled in the art to provide solutions comprising the botanical compound. Some botanical compounds described herein which are not substantially water-soluble or easily solubilized can be suspended or emulsified utilizing techniques known to one skilled in the art. Suitable emulsions include oil-in-water emulsions which can be prepared using suitable emulsifiers having an HLB greater than about 7 or can be water-in-oil emulsions prepared using suitable emulsifiers having an HLB of less than about 7. In order to sufficiently protect the water-soluble and/or hydrophilic compounds from premature oxidation during processing and/or product shelf storage, water-in-oil emulsions are typically particularly useful. The emulsified layer around the water phase can prevent oxygen from entering the water phase.

Alternatively or additionally, the botanical compounds can be encapsulated to prevent premature oxidation during process and product storage. Many encapsulation techniques known in the art can be utilized including those which provide sustained release, triggered release, targeted release or a combination of these release mechanisms. Other release mechanisms known in the art and suitable for use in accordance with the present invention include friction/pressure release, pH related release, water release, water evaporation release, and the like. Encapsulated botanical compounds can be delivered from both wet and dry wipe products. Suitable microencapsulation materials suitable for use in combination with the botanical compounds described herein include those available from Salvona, LLC (Dayton, N.J.).

Additionally, liposomes and/or nanosomes can be utilized to deliver and protect the botanical compounds described herein from premature oxidation in both a wet and a dry wipe product. As used herein, the terms liposomes and nanosomes are meant to include closed vesicles with walls composed of lipid-bilayer membranes to protect and deliver the core compound material.

Another method for delivering botanical compounds from a wet or dry wipe product or absorbent article and protecting these components from premature oxidation includes utilizing polymeric entrapment systems such as microspheres, microsponges, and polytraps such as those available from Advance Polymer Systems (Redwood City, Calif.). The botanical compound can be entrapped or adsorbed into the interstitial spaces of a polymer matrix thereby protecting the botanical compound from degredation and/or premature oxidation.

Particularly useful for delivering the botanical compound from dry substrates are semi-solid or solid formulations which transfer to the skin during use by the consumer. These formulations can be hydrophobic or hydrophilic in nature. The hydrophobic formulations are semi-solid or solid in nature at room temperature with a melting point greater than about 35° C. and contain from about 5 to about 95 weight percent of an emollient, from about 5 to about 95 weight percent of a solidifying agent such as an alpha olefin polymer, polyethylene, oxidized polyethylene, fatty alcohol, wax, or solid esters with a melting point of 35° C. or greater, from about 1 to about 50 weight percent of a viscosity enhancer such as silica, ethylene vinyl acetate copolymers, or an organo-clay and from about 0.1 to about 15 weight percent of an antioxidant agent.

The hydrophilic formulations are semi-solid or solid at room temperature with a melting point greater than about 35° C. and contain from about 30 to about 90 weight percent of a hydrophilic solvent/emollient such as water, propylene glycol, butylene glycol, low molecular weight (less than about 720) polyethylene glycols, dipropylene glycol glycerin, silicone glycols, methyl propanediol, or pentylene glycol, from about 10 to about 50 weight percent high molecular weight (greater than about 750) polyethylene glycol, from about 5 to about 40 weight percent of a fatty alcohol having from about 14 to about 30 carbons in the chain, optionally from about 1 to about 15 weight percent of a viscosity enhancer such as clays, glyceryl polyacrylates, or glyceryl polymethacrylates and from about 0.1 to about 15 weight percent of an antioxidant agent.

The dry wipe formulations can also be readily emulsifiable solid formulations with a melting point greater than about 35° C. and contain from about 5 to about 95 weight percent of a hydrophobic or hydrophilic emollient as set forth above, from about 5 to about 95 weight percent of a suitable solidifying agent as set forth above, from about 5 to about 25 weight percent of a suitable emulsifier and from about 1 to about 15 weight percent of an antioxidant agent. The suitable emulsifier can be anionic, cationic, amphoteric, zwitterionic, or nonioinic and combinations thereof.

In order to enhance consumer appeal, additional ingredients can be added to the above-described formulations. Suitable additional ingredients include, for example, anti-acne actives, antifoaming agents, antimicrobial actives, antifungal actives, antiseptic actives, antioxidants which prevent oxidation during processing and storage by preferentially oxidizing, astringents, colorants, deodorants, film formers, fragrances, moisturizers, skin protectants, sunscreen actives, and solvents.

The present invention is illustrated by the following examples which are merely for the purpose of illustration and are not to be regarded as limiting the scope of the invention or manner in which it may be practiced.

EXAMPLES

Various botanical compounds were tested to determine whether the botanical compound inhibited or enhanced bacterial or yeast attachment to the skin. Tests were also performed to determine if any of these botanical compounds exhibited antimicrobial activity. The botanical compounds and the combined results of these tests are set forth in Tables 1 and 2. Descriptions of the protocols for performing these tests are set forth in the following examples.

Example 1 Bacteria Kill Assay

The ability of various botanical compounds to inhibit the growth of P. mirabilis, P. aeruginosa, and S. epidermidis, was tested. This protocol can also be applied to test the ability of botanical compounds to inhibit the growth of other bacteria, in addition to those tested herein.

To begin, a 10% solution of each botanical in trypticase soy broth (TSB) was prepared by adding either 1 ml or 1 g of botanical to 9 or 10 ml TSB, respectively. Two-fold dilutions of the botanical solutions were performed in a 96 well plate. The dilutions were performed as follows:

    • 10%: 100 ul of the 10% stock is added to the well
    • 5%: 50 ul from the 10% well plus 50 ul TSB
    • 2.5%: 50 ul from the 5% well plus 50 ul TSB
    • 1.25%: 50 ul from the 2.5% well plus 50 ul TSB
    • 0.625%: 50 ul from the 1.25% well plus 50 ul TSB
    • 0.3125%: 50 ul from the 0.625% well plus 50 ul TSB

The final volume in each well was 50 ul after discarding 50 ul from the 0.3125% dilution. All experiments were done in triplicate.

P. mirabilis (ATCC #29906), P. aeruginosa (ATCC #27853), or S. epidermidis (ATCC #12228) were cultured overnight. The overnight culture was diluted with TSB to a concentration of about 1×106 cells/ml. 50 μl of this diluted bacterial culture was added to each well containing the diluted botanical solutions, to form sample solutions comprising diluted bacterial cultures at the concentrations described above and the diluted botanical solution. 50 μl of this diluted bacterial culture was also added to 50 μl TSB and used as a negative control. The optical density (650 nm) of the control and the samples was determined using a spectrophotometer. Both the control and the sample were then incubated for 16 to 18 hours at 37° C., with agitation at about 400 rpm. The wells were again inserted into the spectrophotometer, and further shaken. The optical density (650 nm) of the control and the sample was read again. The percentage of bacterial growth in the sample relative to the control was determined by the following equation:
[(OD650 sample @18 hours—OD650 sample @0 hours)/(OD650 bacteria only @18 hours—OD650 bacteria only @0 hours)]*100

The results for the three wells comprising each dilution step were averaged. The results were plotted, and an IC50 value for each botanical compound was determined.

The results are given in Table 2, which shows the effect of various botanical compounds on the growth of C. albicans, P. aeruginosa, P. mirablis, and S. epidermidis relative to a negative control (compounds not tested are marked with a dash). The lower the IC50 value, the more potent a growth inhibitor the botanical compound was. An IC50 value of greater than 10% indicates that no growth inhibition was observed. Botanical compounds with an IC50 value of 10% or less showed some ability to inhibit growth. However, for purposes of the present invention, botanical compounds that have an IC50 value of about 5% or less are considered growth inhibitors.

Example 2 Yeast Kill Assay

The ability of various botanical compounds to inhibit the growth of C. albicans was tested. The protocol described herein can also be applied to test the ability of botanical compounds to inhibit the growth of other yeast, in addition to C. albicans.

To begin, a 10% solution of each botanical in TSB was prepared by adding either 1 ml or 1 g of botanical to 9 or 10 ml TSB, respectively. Dilutions were performed, as described in Example 1.

C. albicans (ATCC #10231) was cultured overnight. The overnight culture was diluted with TSB to a concentration of about 1×106 cells/ml. 50 μl of this diluted yeast culture was added to each well containing the diluted botanical solutions, to form sample solutions comprising diluted yeast cultures at the concentrations described above and the diluted botanical solution. 50 μl of this diluted yeast culture was also added to 50 μl TSB and used as a negative control. The optical density (650 nm) of the control and the samples was determined using a spectrophotometer. Both the control and the sample were then incubated for 16 to 18 hours at 37° C., with agitation at about 400 rpm. The wells were again inserted into the spectrophotometer, and further shaken. The optical density (650 nm) of the control and the sample was read again. The percentage of yeast growth in the sample relative to the control was determined by the following equation:
[(OD650 sample @18 hours—OD650 sample @0 hours)/(OD650 yeast only @18 hours—OD650 yeast only @0 hours)]*100

The results for the three wells comprising each dilution step were averaged. The results were plotted, and an IC50 value for each botanical compound was determined. The results are given in Table 2, as described in Example 1.

Example 3 Adhesion Assay for P. mirabilis, S. epidermidis, and P. aeruginosa

Each of the botanical compounds listed in Table 1 was screened to measure the effect of the compound on the adhesion of P. mirabilis, S. epidermidis, or P. aeruginosa to the skin. The protocol described herein can also be applied to test the effect of botanical compounds on the adhesion of other bacteria to the skin.

Two days prior to the screen, a bacterial culture of either P. mirabilis (ATCC #29906), S. epidermidis (ATCC #12228), or P. aeruginosa (ATCC #27853) was prepared. One frozen bead of bacteria was added to 10 ml of TSB, and grown overnight at 37° C. with agitation at 100 rpm. A synthetic skin substrate (VITRO-SKIN® substrate) was placed in a hydration chamber overnight.

One day prior to the screen, discs of the synthetic skin, sized to fit the wells of a 96 well plate, were cut out in a controlled humidity room using a #2 tool. The discs were placed in the wells of the plate, and the plate was stored in a humidity chamber. A TSB culture was prepared by inoculating TSB with the overnight culture, previously described, at a ratio of 1:1000 (overnight culture:TSB). The TSB culture was then grown overnight at 37° C. with agitation at 100 rpm. A 10% solution of each botanical in TSB was prepared by adding either 100 μl of botanical to 900 μl TSB, or if the botanical was a solid, using 100 mg of botanical and a sufficient amount of TSB to bring the total volume to 1 ml. 10% Tween® 20 stock in TSB was prepared as a positive control by adding 100 μl of Tween® 20 to the appropriate amount of TSB, to give a 10% solution.

The next day, the optical density (650 nm) of the TSB culture was read. It was assumed that 1 OD was equal to 1×108 cells/ml. The culture was centrifuged at 5,000×g for 10 minutes to pellet the bacteria. The bacteria were resuspended in a sufficient amount of TSB, so that the final concentration of bacteria was 1×106 cells/ml. 50 μl of either the 10% botanical stock or the control solution was added to wells containing the synthetic skin substrate. 50 μl of the bacteria in TSB was then added to each of these wells, and the cells were allowed to adhere to the synthetic skin for three hours at room temperature, shaking slowly. After three hours, the solutions were removed from the wells, and the synthetic skin was washed three times with a solution of 250 μl of phosphate buffered saline (PBS) plus 0.05% Tween® 20. The skin was transferred to a white plate, and 200 μl of 10% AlamarBlue® dye in TSB was added to each well. The plate was incubated at 37° C. AlamarBlue® levels were read (emission levels read at 590 nm) in an Ascent plate reader (excitation level of 544 nm) at 1 and 2 hours. When not being read, the plate was incubated at 37° C. with a lid.

Results are given in Table 1, which gives the percent adherence to the skin of P. mirabilis, S. epidermidis, P. aeruginosa, L. acidophilus, and C. albicans for the various botanical compound samples, relative to the control. The percentage is based on the number of cells that adhered to the skin for the botanical samples as compared to the number of cells that adhered to the skin in the control, as determined by the AlamarBlue® levels. A percentage greater than 100% indicated that more cells adhered with the botanical sample than with the control; a percentage less than 100% indicated that fewer cells adhered with the botanical sample than with the control. For purposes of the present invention, if the percentage is 150% or greater, the botanical compound is considered to be an adherence promoter for the particular organism; if the percentage is 50% or lower, the botanical compound is considered to be an anti-adherent for the particular organism.

Some of the compounds in Table 2 that are listed as growth inhibitors for certain organisms have a percent adherence of less than 50% for that organism. In this situation, no conclusion can be drawn as to the anti-adherent properties of the botanical compound, as it is unclear whether the low percent adherence is due to anti-adherent properties of the botanical compound, or to the compound's growth inhibiting properties.

Example 4 Adhesion Assay for Lactobacillus acidophilus

Each of the compounds listed in Table 1 was screened to measure the effect of the compound on the adhesion of Lactobacillus acidophilus to the skin.

Two days prior to the screen, a bacterial culture of Lactobacillus acidophilus was prepared. One frozen bead of Lactobacillus acidophilus (ATCC #:314) was added to 10 mL of Lactobacilli broth, and the culture was incubated overnight at 37° C. A synthetic skin substrate (VITRO-SKIN® substrate) was placed in a hydration chamber overnight.

One day prior to the screen, discs of the synthetic skin, sized to fit the wells of a 96 well plate, were cut out using a #2 tool. The discs were placed in the wells of the plate, and the plate was stored in a humidity chamber. A Lactobacilli broth culture was prepared by inoculating Lactobacilli broth with the overnight culture, previously described, at a ratio of 1:1000 (overnight culture: Lactobacilli broth). The Lactobacilli broth culture was grown overnight at 37° C. A 10% solution of each botanical in TSB was prepared by adding either 1 ml of botanical to 9 ml TSB, or if the botanical was a solid, using 1 g of botanical and a sufficient amount of TSB to bring the total volume to 10 ml. 10% Tween® 20 stock in TSB was prepared as a positive control, by adding 1 mL Tween® 20 to 9 ml of TSB.

The next day, the optical density (650 nm) of the Lactobacilli broth culture was read. 1 OD is approximately, 1×109 cells/ml. The culture was centrifuged at 5,000×g for 10 minutes to pellet the bacteria. The bacteria were resuspended in a sufficient amount of TSB, so that the final concentration of bacteria was 1×106 cells/ml. 50 μl of either the 10% botanical stock or the control solution was added to wells containing the synthetic skin substrate. 50 μl of the bacteria in Lactobacilli broth was then added to each of these wells, and the cells were allowed to adhere to the synthetic skin for three hours at either 33° C. or 37° C. After three hours, the solutions were removed from the wells, and the synthetic skin was washed in the wells three times with a solution of 250 μl of PBS plus 0.05% Tween® 20. The skin was transferred to a white plate, and 200 μl of 10% AlamarBlue® dye in TSB was added to each well. The plate was incubated at 37° C. AlamarBlue® levels were read (emission levels read at 590 nm) in an Ascent plate reader (excitation level of 544 nm) at 2 and 3 hours. When not being read, the plate was incubated at 37° C. with a lid.

Results are given in Table 1, which is described in Example 3.

Example 5 Adhesion Assay for Candida albicans

Each of the compounds listed in Table 1 was screened to measure the effect of the compound on the adhesion of C. albicans to the skin. The protocol described herein can also be applied to test the effect of botanical compounds on the adhesion of other yeast to the skin.

Two days prior to the screen, a culture of C. albicans was prepared. One frozen bead of C. albicans (ATCC #10231) was added to 10 ml Saboraud's dextrose broth (“SDB”), and grown overnight at 37° C. with agitation at 150 rpm. A synthetic skin substrate (VITRO-SKIN® substrate) was placed in a hydration chamber overnight.

One day prior to the screen, discs of the synthetic skin, sized to fit the wells of a 96 well plate, were cut out in a controlled humidity room using a #2 tool. The discs were placed in the wells of the plate, and the plate was stored in a humidity chamber. A SDB culture was prepared by inoculating SDB with the overnight culture, previously described, at a ratio of 1:1000 (overnight culture:SDB). The SDB culture was then grown overnight at 37° C. with agitation at 150 rpm. A 10% solution of each botanical in TSB was prepared by adding either 1 ml of botanical to 9 ml TSB, or if the botanical was a solid, using 1 g of botanical and a sufficient amount of TSB to bring the total volume to 10 ml. 10% Tween® 20 stock in TSB was prepared as a positive control, by adding 1 mL of Tween® 20 to 9 ml of TSB.

The next day, the optical density (650 nm) of the SDB culture was read. It was assumed that 1 OD equals 1×108 cells/ml. The culture was centrifuged at 5,000×g for 10 minutes to pellet the yeast. The yeast were resuspended in a sufficient amount of TSB, so that the final concentration of yeast was 1×106 cells/ml. 50 μl of either the 10% botanical stock or the control solution was added to the wells containing the synthetic skin substrate. 50 μl of the yeast in TSB was then added to each of these wells, and the cells were allowed to adhere to the synthetic skin for three hours at 33° C., shaking slowly. After three hours, the solutions were removed from the wells, and the syntehtic skin was washed in the wells three times with a solution of 250 μl of PBS plus 0.05% Tween® 20. The skin was transferred to a white plate, and 200 μl of 10% AlamarBlue® dye in TSB was added to each well. The plate was incubated at 37° C. AlamarBlue® levels were read (emission levels read at 590 nm) in an Ascent plate reader (excitation level of 544 nm) at 2 and 3 hours.
