Polyurethane-71
Used in cosmetic products as binding and film forming. Polyurethane-71 is a complex polymer that is formed by a multi-step synthesis. First, a polyester diol made by condensing Hexanediol, Adipic Acid, and isophthalic acid is reacted with isophorone diisocyanate and dimethylolpropionic acid. The resulting pre-polymer is neutralized with Triethylamine. The neutralized polymer is dispersed in water with Isopropanolamine and ethylene diamine.
