A proteinous emulsifier is obtained by reacting an amino acid ester with a hydrophilic protein in the presence of endopeptidase to bind the amino group of the amino acid ester to the carboxyl terminal of a hydrophilic protein decomposition product through an amide bond. This emulsifier has a typical surfactant structure wherein the hydrophobic amino acid ester moiety is bound to the end of the hydrophilic protein moiety. It slightly stimulates skin and shows a strong emulsifying effect and a good moisture retention, thus being extremely suitable as emulsifier for various cosmetic preparations such as creams, milky lotions, etc.
