ABSTRACT:
Emulsified compositions comprising an elastin hydrolyzate having a molecular weight not lower than 200,000 (preferably in the range from 1,000,000 to 2,000,000) maintain a stable emulsion state without having to use any other surfactants, and cause sufficient retention of water and moisture on the human skin without having to use any other humectants when employed as cosmetics or external preparations for the skin.
