Abstract
An antiperspirant/deodorant liquid composition comprising a solvent, an antiperspirant and/or deodorant ingredient, a fragrance, and an alkylated polyvinylpyrrolidone, wherein the alkylated polyvinylpyrrolidone is soluble or dispersible in the composition. The alkylated polyvinylpyrrolidone is capable of forming a film when the solvent is allowed to evaporate such that the film limits the release of the fragrance. Fragrance is released when the film is exposed to perspiration. The alkylated polyvinylpyrrolidone overcomes the problem with other film forming polymers that do not form stable films in the presence of an antiperspirant and/or deodorant ingredient.
