Abstract
The present invention relates to an amino acid-modified organopolysiloxane emulsion obtainable by reacting (a) a carboxy-unprotected amino acid, and (b) organopolysiloxane having an epoxy group in the molecule in an aqueous medium in the presence of a surfactant, is incorporated in a cosmetic product. The present invention also relates to the simple and highly efficient production of emulsions of amino acid-modified polysiloxane, as well as the use of the emulsions as beautifying components.
