Modified soy proteins in skin tightening compositions

摘要

A method of bringing about a tightening effect of skin (preferably human skin) comprising applying to the skin a composition comprising an effective amount of a modified soy protein is described. The soy proteins of the instant invention include soy proteins modified by treatment with a reducing agent and subsequently reacted with a carboxylic acid anhydride; soy proteins modified by treatment with a reducing agent, reacted with a carboxylic acid anhydride and subsequently oxidized; soy proteins modified by reaction with a hydroxy alkyl acrylate; soy proteins modified with ionic monomers such as epoxide, acrylate, and chlorohydrin; and soy proteins modified by reaction with an alkyl acrylimidoglycolate.
