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.
