Abstract: Personal care products comprising supersaturated solutions and core compositions comprising activation means are disclosed. In one embodiment, a core composition comprising the activation means is surrounded by an encapsulation layer. The core composition comprising the activation means may be introduced into wet wipes such that, upon rupture and contact between the supersaturated solution and the activation means, the wet wipe solution is warmed resulting in a warm sensation on a user's skin. Any number of other active ingredients, such as biocides, can also be incorporated into the personal care product.

Abstract: Reactive chemistries for warming personal care products are disclosed. In one embodiment, one reactant of the chemistry is encapsulated in a microencapsulated composition. Upon rupture, the microencapsulated composition releases the reactant and the reactant can contact a second reactant in the reactive chemistry, located in either an aqueous solution or a second microencapsulated composition, generating heat. The reactants of the reactive chemistries may be introduced into wet wipes such that, upon activation, the wet wipe solution is warmed resulting in a warm sensation on a user's skin.

Abstract: A fluid storage material including particles, such as superabsorbent particles and/or microencapsulated fragrance agents, cleansing agents, or skin rejuvenation agents, secured to one another and/or secured to a substrate. The fluid storage material can be made by dispersing particles in a crosslinkable binder solution, applying the combined particles and binder solution to a surface such as a substrate or a release surface, inducing crosslinking of the binder, and removing the solvent from the surface such as, for example, by drying the solvent. The fluid storage material is particularly suitable for use in personal care products.

Abstract: A process for making an absorbent material involves flash-drying a superabsorbent polymer precursor composition. The process may be used to make a superabsorbent-fiber material without the necessity of mixing conventional superabsorbent solid particles with pulp fluff is provided. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the absorbent material. One or more streams of superabsorbent polymer precursor composition are provided, to which a plurality of individual fibers may be added. The resulting in-situ polymerized superabsorbent-fiber material is then flash-dried and can subsequently be formed into a superabsorbent-fiber composite. The flash-drying is relatively inexpensive and requires little drying time compared to conventional drying methods.

Abstract: Airlaid paper wiping products are disclosed having improved wipe dry characteristics in conjunction with softness properties. The wiping products are formed from an airlaid nonwoven web containing pulp fibers. The pulp fibers, in one embodiment, may include low coarseness softwood fibers, such as low coarseness softwood fibers. A bonding material may be applied to one or both sides of the nonwoven web. The wiping product can be used as a paper towel, industrial wiper, and the like.

Abstract: Methods are disclosed for producing absorbent articles comprising molded airlaid webs and other molded fibrous webs. The molded webs can offer improved body fit and/or improved fluid handling. Molded airlaid webs, for example, can be formed having a central longitudinal hump and flexure zones longitudinally removed from the central hump to provide good contact with the body and improved fit when the article is squeezed from the sides. Molding can be achieved when a binder material is activated by an energy source and the web is held against a molding substrate. Energy sources can include microwaves, heated air, heated metal surfaces, ultraviolet radiation, ultrasonic energy, and the like.

Abstract: An absorbent binder composition including a monoethylenically unsaturated polymer, such as carboxylic acid, sulphonic acid, or phosphoric acid, or salts thereof, and an acrylate or methacrylate ester that contains an alkoxysilane functionality, or a monomer capable of co-polymerization with a compound containing a trialkoxy silane functional group and subsequent reaction with water to form a silanol group. The absorbent binder composition is particularly suitable for use in manufacturing absorbent articles. A method of making the absorbent binder composition includes preparing a monomer solution, adding the monomer solution to an initiator solution, and activating a polymerization initiator within the initiator solution.

Abstract: This invention relates to a containment tissue of an absorbent article such as a diaper, treated to have regions with hydrophobic properties to maximize the strength of the containment tissue when wet. The result is less superabsorbent material contacting the user and therefore less skin irritation. Additional benefits of this invention include enhanced leakage protection and reduced skin wetting, which also reduces skin irritation. A hydrophobic agent such as a sizing agent or adhesive is used to create zones of water resiliency on the containment tissue in various regions, patterns, and/or configurations. The treatments of the containment tissue are applied by known application methods such as gravure printing, spraying, or ink jet printing. Liquid insults easily wick through untreated containment tissue but stop at the boundaries of treated regions. This provides a method of leakage control when wicking is halted before the liquid reaches the edges of the absorbent article.

Abstract: This invention relates to an improvement in a disposable absorbent article such as a sanitary napkin, etc. having a liquid permeable cover sheet or cover sheet, optionally a distribution or transfer layer, an absorbent core and a liquid-impermeable backsheet. The improvement in the disposable absorbent article resides in an improved bond for generally continuous contact between the cover sheet and the transfer layer or absorbent core. Adhesion is effected by applying an adhesive binder to the top sheet with a print roller.

Abstract: A low density compression resistant cellulosic-based nonwoven fabric having good absorbency and et tensile strength is formed from cellulosic-based fibers which are treated for use in an air laid process, with an aqueous dispersion of a self-crosslinkable polymeric binder and a chemical stiffening agent for the cellulose fibers and then dried at temperatures that result in intrafiber crosslinking and interfiber binding. The cellulosic-based nonwoven fabrics, thus formed, are useful in personal care products such as diapers and feminine care products.
