Polyurethane-26
A cosmetic ingredient used as film forming, hair conditioning, skin protecting in skincare, haircare, and personal-care products sold in the European Union.
What is it?
Polyurethane-26 is a complex polymer that is formed by the reaction of Polyperfluoroethoxymethoxy Difluorohydroxyethyl Ether and isophorone diisocyanate (IPDI) to form a prepolymer. The prepolymer is further reacted with 3-diethylamino-1,2-propanediol followed by the capping of any residual isocyanate groups with 2-ethyl-1-hexanol. The resulting polymer is neutralized with acetic acid
