Abstract
Abstract The invention is directed to a cosmetic product comprising a powder/oil dispersion having high levels of cosmetic powder. More particularly, it is directed to an antiperspirant where at least part of the powder content is an astringent, such as aluminum chlorhydrate. By using one or more cationic or nonionic surfactants in an oily vehicle, a highly concentrated, stable dispersion having relatively low viscosity and creamy consistency, with a dry, non-oily feel is obtained.
