Abstract
Abstract Amino alkyl silicones modified by reaction with epoxide groups, thereby alkylating the amines. The alkylated amines show decreased reactivity toward aldehydes which may be present in consumr products. The modified amino alkyl silicones may be used in dentifrices and other consumer products.
