  • Patent number: 9458419
    Abstract: This invention relates to an aqueous polymer composition and to films formed from this aqueous composition. The aqueous composition may be used in a method for removing contaminate material from a substrate. The aqueous polymer composition may comprise: water; and at least one water-soluble film forming polymer. In one embodiment, the aqueous composition may further comprise at least one chelating agent and/or at least one surfactant. The aqueous polymer composition may be applied to a contaminated substrate or to a clean substrate which is subjected to subsequent contamination. The aqueous composition may be dehydrated and/or the polymer may be crosslinked to form a film. When applied to a contaminated substrate, the film may combine with the contaminates. When applied to a clean substrate, the contaminate material may subsequently contact and adhere to the film.

  • Publication number: 20140328776
    Abstract: Compositions, kits and methods of preparing a biocompatible film for cosmetic or medical uses are disclosed. The compositions or kits contain polyvinyl acetal (PVA), siloxane and a solvent. The siloxane can have a hydrophilic group. Once the solvent content is reduced, for instance, by evaporation, the mixture of PVA and siloxane is solidified, forming a film. The compositions and kits, optionally, further include one or more of an antimicrobial agent, a pigment, an anti-inflammatory agent, an anesthetic agent or a hemostatic agent. Such a film can be used, for example, in the form of an antimicrobial sealant, a liquid bandage, body paints, scar camouflage, water-proof sun block, makeup sealer, or antimicrobial wipe or spray.

  • Publication number: 20130287834
    Abstract: Liquid formulations having anti-adherent properties are disclosed herein. The liquid anti-adherent formulation described herein acts to prevent the adherence of menses and/or fecal material to the skin in the labial and perianal regions during and after menstruation or defecation, respectively. The liquid anti-adherent formulation contains a carrier, a polymer selected from a nonionic acrylate co-polymer, cationic acrylate co-polymer, and combinations thereof. Anti-adherent formulation is found to be effective if a menses leave-on percentage as defined within the Menses Leave-On Percentage Test method described herein was less than 6.2% after two insults.

  • Publication number: 20120171267
    Abstract: The present invention relates to compositions having durable antimicrobial activity. The compositions include a carbonate/bicarbonate salt of a quaternary ammonium cation, an organic acid, hydrogen peroxide and a cationic polymer. The cationic polymer includes either a (3-acrylamidopropyl)trimethylammonium chloride monomer or a [2-(acrylolyoxy)ethyl]trimethylammonium chloride monomer. The cationic polymer also includes another monomer selected from a polar, water-soluble monomer, a hydrophobic, silicone-containing monomer or mixtures of both types of monomers in combination with one of the trimethylammonium chloride monomers.
