Abstract
Abstract This invention relates to a surfactant with less toxicity and irritation against the human body and a production process thereof. The surfactant is produced by the acylation of the side chain amino radicals of collagen or gelatine with an aliphatic acid having 2 to 26 carbon atoms; it is used as an emulsifier and an antiseptic for cosmetics.
