Polyurethane-46
Used in cosmetic products as hair conditioning. Polyurethane-46 is a complex urethane-based polymer. Initially, a pre-polymer is made by the reaction of isophorone diisocyanate (IPDI) with three different polyols. The polyols are poly(1,4-butanediol)-30, methoxy PEG-20 terminated with a 2,2 dimethyol butoxy group, and Methyl Diethanolamine .
