  • Patent number: 6462252
    Abstract: Absorbent articles such as diapers, incontinence protectors, sanitary napkins, wound dressings and similar articles which are applied in contact with skin, and methods which make it possible to use an article for an extended period of time without the appearance of unwanted side-effects such as, for instance, growth of undesirable microorganisms. The absorbent body in the absorbent article comprises a pH-controlling substance in the form of a partially neutralized super-absorbent material in such a manner that the pH in the absorbent article after wetting is in the interval 3.5-4.9. Growth of undesirable strains of microorganisms is prevented and unwanted side-effects resulting from use of the article are reduced.

  • Patent number: 5885263
    Abstract: Compositions which greatly diminish, or eliminate, unpleasant smells associated with the use of underwear and diapers are described. These compositions are composed of superabsorbent polymers of the polyacrylic type and of certain boron derivatives, in particular sodium tetraborate. The sanitary articles which incorporate these compositions do not develop unpleasant smells, ammoniacal or otherwise.

  • Patent number: 5856248
    Abstract: Cellulose fibers and products comprising such fibers treated to absorb body secretions and to substantially decrease microbial growth, said fibers being chemically treated with a water soluble salt of a transition metal and an alkali and after this with a solution of a bisbiguanide compound, forming a bond between the fibers, the transition metal and the bisbiguanide. Preferred are water-soluble cupric salts as a suitable hydroxide. A preferred bisbiguanide is chlorhexidine. The products can be yarns, knitted, woven, non-woven fabrics, paper gauze and especially bandages, wound dressings, pads, diapers, sanitary napkins, tampons, bed sheets, pants, garments, towels, socks, shoe linings and underwear. Preferably between 0.1 to 3.0 weight per cent copper calculated on the cellulose is bonded to the cellulose.

  • Patent number: 5783502
    Abstract: Reagents and methods are disclosed for modifying a fabric substrate in order to inactivate viruses, and particularly lipid-enveloped viruses, upon contact. Such substrates can be modified by photochemically immobilizing hydrophilic polymers containing both quaternary ammonium groups and hydrocarbon chains, resulting in a localized surfactancy capable of disrupting lipid-enveloped viruses upon contact with the substrate. Substrates of the invention can be fabricated into the form of articles for medical and related use.

  • Patent number: 5753252
    Abstract: Absorbent products, especially catemenial tampons, for absorbing body fluids, such as menstrual fluid, blood and wound exudates, comprise an amount of a compound effective to inhibit the production of Enterotoxin A, Enterotoxin B and/or Enterotoxin C by Staphylococcus aureus bacteria when the products are brought into contact with the bacteria. The compositions of this invention are also useful to inhibit production of Streptococcal pyrogenic exotoxins A, B and C, as well as hemolysins produced by Groups A, B, F and G streptococci in solution as well as being expected to be effective to inhibit such toxin and hemolysin production when used in conjunction with absorbent products. The compound is selected from the group consisting of monoesters of a polyhydric aliphatic alcohol and a C.sub.8 -C.sub.18 fatty acid; diesters of a polyhydric aliphatic alcohol and a C.sub.8 -C.sub.18 fatty acid; and mixtures thereof.

  • Patent number: 5733272
    Abstract: The present invention comprises compositions and articles such as catamenials, diapers, pantiliners, adult incontinence garments, and underarm shields which minimize odor caused by body fluids and which provide a pleasant scent signal to indicate that the odor is being removed. This scent signal, provided by cyclodextrin/perfume inclusion complexes and/or matrix perfume microcapsules, assures the wearer that the product is working.
