Abstract

Cosmetic agents for the temporary color change of keratinous surfaces, in particular human hair and human skin, contain an alcohol having 2 to 8 carbon atoms, a special anionic polymer, and a pigment. These cosmetic agents have an extremely good water resistance but can be removed without residue with a single application of surfactant-containing detergents. In addition, methods of temporary staining keratinous fibers and the skin using these agents are provided.
