Abstract
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.
