Abstract:
An improved anhydrous denture adhesive is prepared to contain a mixture of a cationic polymeric material and an anionic protein material as the adhesive ingredient. The mixture may be formulated as a powder or anhydrous paste, which, when applied to dentures and exposed to moisture, develops superior adhesive properties. Suitable cationic materials include at least one of the following: copolymers of substituted or unsubstituted acrylamide with vinyl quaternary ammonium salts; copolymers of substituted or unsubstituted acrylamide with vinyl and alkyl substituted vinyl pyridinium salts; and an 0-lower alkyltrimethylammonium chloride-substituted-anhydroglucose polymer. As the anionic component there may be used at least one protein material, such as soybean meal, sunflower seed meal or peanut meal.

Abstract:
Water-wettable anhydrous products, such as the powders and creams used in cosmetic and drug products, are admixed with 20% to 60% by weight, based on the weight of the total formulation, of a powdered polyethylene or powdered polypropylene polymer, to improve wettability characteristics. Denture adhesive powders prepared from an anionic/cationic adhesive combination, together with the powdered polyethylene or polypropylene polymer display particularly improved properties. The polyethylene or polypropylene polymer may also be admixed with other anhydrous products including dentifrices, vaginal powder sprays, and the like. Low molecular weight polyethylene powder, with an average molecular weight of from 1,000 to 3,500, is suitable for use in products of the invention. For the polypropylene, a molecular weight of from 120,000 to 350,000 is specified. The powdered polymers have a particle size of less than 422 microns.
