  • Use of finely divided dye-containing polymers PD as color-imparting constituent in cosmetic compositions
    Patent number: 6541032
    Abstract: The present invention describes the use of finely divided dye-containing polymers PD in the form of an aqueous polymer dispersion or a polymer powder obtainable therefrom, the polymer matrix of which comprises at least one organic dye D in homogeneously dispersed form, as color-imparting constituent in cosmetic compositions. The present invention also describes cosmetic compositions which comprise a color-containing polymer in an amount of from 0.1 to 50% by weight, based on the total weight of the cosmetic composition, and additives customary for cosmetic compositions.

  • Aqueous cosmetic compounds
    Patent number: 6335005
    Abstract: The use of an emulsion polymer in aqueous cosmetic compositions, wherein the emulsion polymer is obtainable by emulsion polymerization of a monomer mixture A comprising from 50 to 100% by weight, based on the monomer mixture, of C1-C18 alkyl (meth)acrylates, vinyl esters, vinylaromatic compounds or mixtures thereof in the presence of a polymer B which has been built up from b1) from 5 to 50% by weight of monomers having at least one ionic group or one group which can be converted into an ionic group, b2) from 0 to 95% by weight of C1-C18 alkyl (meth)acrylates, vinyl esters, vinylaromatic compounds or mixtures thereof, and b3) from 0 to 50% by weight of further monomers, the glass transition temperature of the polymer built up from monomer mixture A being less than or equal to that of the polymer B.
