Abstract
Moisturizing compositions for application to human skin which contain oxyethylene functional organosilanes. When used in skin care applications, these compounds exhibit humectant properties. The oxyethylene functional organosilane is a compound having the formula RSiR'.sub.3 in which R is the radical --O(CH.sub.2 CH.sub.2 O).sub.x R"; R' is an R group or an alkyl radical having one to six carbon atoms; R" is a radical such as hydrogen; an alkyl group of one to six carbon atoms; and an aryl group; and x is an integer having a value of six to thirty.
Claims21
A method of moisturizing skin comprising applying to the skin a skin conditioning composition which comprises 0.1 to 20.0 percent by weight based on the total weight of the skin conditioning composition of a skin conditioning agent which is an oxyethylene functional organosilane compound having the formula RSiR'.sub.3 in which R is the radical --O(CH.sub.2 CH.sub.2 O).sub.x R";
