Abstract: This invention relates to a nonwoven material comprising an adhesive comprising polyhydroxyalkanoate (PHA). This invention also relates to an absorbent article comprising such nonwoven material. This invention also relates to a composition comprising PHA and a surfactant. This invention relates to a method for preparing the nonwoven material.
Abstract: Skin wetness is minimized on overnight usage of a disposable absorbent article containing an acquisition and distribution member consisting essentially of C.sub.2 -C.sub.9 polycarboxylic acid crosslinked cellulosic fibers prepared in the presence of surfactant.
Abstract: A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 5 to about 15% by weight, and tissue paper treated with such lotion compositions are disclosed. The lotion composition comprises plastic or fluid emollient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, an immobilizing agent such as a fatty alcohol or fatty acid to immobilize the emoilient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided.

Abstract: A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 0.1 to about 15% by weight, and tissue paper treated with such lotion compositions are disclosed. The lotion composition comprises a liquid polyol polyester emollient and an immobilizing agent to immobilize the liquid polyol polyester emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided.

Abstract: Fibrous cellulose materials useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a vegetable oil based quaternary ammonium chemical softening compound. Examples of preferred vegetable oil based quaternary ammonium chemical softening compounds include diester di(oleyl)dimethyl ammonium chloride (DEDODMAC) (i.e., di(octadec-z-9-eneoyloxyethyl)dimethyl ammonium chloride) derived from canola oil and/or high oleic safflower oil. Variables that need to be adjusted to maximize the fluidity of vegetable oil based acyl groups include the cis/trans isomer ratio or the Iodine Value (IV) of the fatty acyl groups. The tissue softness is further enhanced by controlling the purity of the fatty acyl groups and the di-substituted versus mono-substituted long chain hydrocarbyl substituent ratio in the quaternary ammonium compounds.
Abstract: Disclosed is a fiber comprising, chemically bonded together, (a) a conventional cellulosic fiber, such as a Kraft fiber or a chemithermomechanical pulp fiber; (b) poly(acrylate-co-itaconate) copolymer, such as the acid form of a poly(acrylate-co-itaconate) copolymer comprising 90-95 mole % acrylate and 5-10 mole % itaconate having weight average molecular weight of about 600,000-900,000; and (c) a polyol, such as polyethylene glycol; also disclosed are methods for making such fibers, especially evaporatively depositing an intimate mixture of the copolymer and polyol on the fiber followed by thermally crosslinking at specific temperatures for limited periods; absorbent paper which can be made by wet-laying the fiber, especially in admixture with conventional fiber; and derivative paper structures, such as multi-ply disposable absorbent towels.

Abstract: A method for generating new bone growth in a mammal comprising administrating to the mammal a safe and effective amount of a Vitamin D compound in combination with a safe and effective amount of osteoinductive extract or at least one BMP.
Abstract: Tissue paper webs useful in the manufacture of soft, absorbent sanitary products such as bath tissue, facial tissue, and napkins are provided. The composite average coarseness of the tissue papers is between about 11 mg/100 m and about 18 mg/100 m. The tissue paper comprise closed cell wall, chemically softened cellulose fibers further comprising coarse cellulose fibers such as those derived from CTMP or recycled sources. The cellulose fibers have enhanced lubricity such that they possess a depressed coefficient of friction (DCOF, in percentage points) related to the composite average coarseness, C, in mg/100 m, by the equation:DCOF>4.27*C-44.23.

Abstract: A diaper containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition reduces the adherence of BM to the skin of the wearer, thereby improving the ease of BM clean up. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the diaper topsheet, and optionally a hydrophilic surfactant to improve wettability of the coated topsheet. Because the emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

Because the polysiloxane emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.
Abstract: Soft creped tissue paper products comprising papermaking fibers and a crepe facilitating composition are disclosed. The crepe facilitating composition comprises a bonding inhibitor, a cationic starch and a carboxymethyl cellulose. Preferably, the bonding inhibitor is a quaternary ammonium compound. The use of a bonding inhibitor, a cationic starch and a carboxymethyl cellulose results in a creped tissue paper that is both strong and soft. A creped papermaking process comprising the addition of the crepe facilitating composition is also disclosed. The crepe facilitating composition offers the potential to improve production capacity.
