A combination of polyion complex particles and non-polymeric acids having two or more acid dissociation constants

摘要

The present invention relates to a method for preparing an aqueous dispersion comprising (a) at least one particle comprising at least one cationic polymer, at least one anionic polymer, and at least one non-polymerizable acid or salt thereof having at least two pKa values; And (b) at least one physiologically acceptable volatile medium. The composition according to the invention is stable and can have a variety of cosmetic functions. For example, the composition according to the present invention may be used for the absorption or adsorption of odor, the appearance change of the keratin substrate such as the skin, the change of tactile properties of the keratin substrate, and / or the cosmetic effect Can be provided.
