Abstract: The invention relates to the use of an emulsion polymer in aqueous cosmetic compounds. The emulsion polymer is obtained by emulsion polymerization of a monomer mixture (A) containing 50-100 wt.%, in relation to the monomer mixture, C1-C18 alkyl(meth)acrylates, vinylesters, vinyl aromatics or their mixtures, in the presence of a polymer (B). Said polymer (B) is composed of b1) 5-50 wt.% monomers with at least one ionic group, or group that can be converted to an ionic group, b2) 0-95 wt.% C1-C18 alkyl(meth)acrylates, vinylesters, vinyl aromatics or their mixtures, and b3) 0-50 wt.% other monomers. The glass transition temperature of the polymers obtained from monomer mixture (A) is lower than or equal to the glass transition temperature of polymer (B).

Abstract: The invention concerns the electrochemical preparation of dicarboxylic acids by subjecting an aqueous solution containing essentially the alkali-metal salt of a dicarboxylic acid of the general formula (I): HOOC-(CH2)n-COOH, in which n may be an integer from 1 to 8, or mixtures of such dicarboxylic acids, to an electrochemical treatment.
