摘要:
Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. In some embodiments, the fibers comprise a viscosity modifier and/or an anionic surfactant. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.

Nitric oxide releasing compositions, which comprise nanoparticles having an exterior surface comprising solid amorphous silica, the exterior surface having nitrosothiol-containing groups attached thereto, the nanoparticles being dispersible in an aqueous system, devices including the compositions, and methods of making and using the compositions and devices are disclosed.
摘要:
Polypropylene fibers and devices that include a fatty acid monoglyceride added to the polypropylene as a melt additive are described. A hydrophilic enhancer material can be advantageously added to the polypropylene as a melt additive to enhance the hydrophilicity of the fibers and devices. An antimicrobial enhancer material can be added to the fibers to enhance the antimicrobial activity.

摘要:
A method of moisturizing while decolonizing mammalian tissue, the method comprising applying a multi-valent cationic antiseptic composition to the tissue, and applying a moisturizer composition to at least a portion of the same tissue; wherein the mammalian tissue is oral tissue of a subject; wherein the multi-valent cationic antiseptic is other than a metal ion; and wherein the applied compositions essentially exclude any component which causes a precipitate when combined with a multi-valent cationic antiseptic contained in the multi-valent cationic antiseptic composition when tested according to Test Method F, and/or wherein the moisturizer composition is such that a log reduction in the number of viable bacterial cells of at least 2 is provided when 106 cfu of Pseudomonas auerginosa are combined with a mixture 1.1 g of the moisturizer composition and 1.5 g of the multi-valent cationic antiseptic composition containing 0.12 weight percent of the multi-valent cationic antiseptic according to Test Method B; an oral care kit comprising a composition comprising the multi-valent cationic antiseptic and the moisturizer composition; and a method of moisturizing oral tissue of a patient requiring intubation using the moisturizer composition and an endotracheal tube coated or impregnated with a cationic antiseptic are provided.
摘要:
A hydroalcoholic lotion is disclosed which comprises (a) a lower alcohol and water in a weight ratio of about 35:65 to 100:0, and (b) between at least 0.5% and 8% by weight thickener system comprised of at least one emulsifier present in at least 0.05% by weight wherein the composition in a polymer free state has a viscosity of at least 4,000 centipoise at 23 degrees C. and wherein the emulsifier is comprised of at least one hydrophobic group and at least one hydrophilic group. The hydroalcoholic composition is useful as a hand preparation such as a lotion or as a presurgical scrub replacement.
摘要:
An iodine/iodide-containing hot melt coatable adhesive is provided. This adhesive is prepared by mixing iodine and an iodide salt, individually or in combination, with solubilizing liquids. The iodine and iodide salt are combined with a pre-adhesive composition in a hot melt mixer, with an iodine/iodide complexing agent being present in the mixture. The mixture is mixed at a temperature from about 130° C. to about 200° C. and sufficiently to form an iodine/iodide-containing hot melt coatable adhesive. Alternatively, the iodide may be generated in situ. The adhesive so prepared may be packaged for coating on a substrate at a later time, or may be immediately coated to form an adhesive composite. Adhesive composites, particularly surgical incise drapes, are provided incorporating this hot melt coatable adhesive.
摘要:
Methods of delaying the onset of an infection or preventing an infection caused by a microbial organism in an internal cavity of a subject are provided. Methods of killing or inactivating microorganisms in at least a portion of the urethra of a subject are provided.
摘要:
Polymeric fibers and methods of making the polymeric fibers are described. The polymeric fibers are crosslinked hydrogels or dried hydrogels that are prepared from a precursor composition that contains polymerizable material having an average number of ethylenically unsaturated groups per monomer molecule greater than 1.0. The polymeric fibers can contain an optional active agent.
