Polyurethane-8 is a synthetic plastic-like polymer that forms a flexible, protective coating on skin or hair. It's a common ingredient used to create water-resistant formulas that stay in place longer.

This ingredient helps cosmetic products adhere to skin or hair, form a flexible film layer, and adds flexibility to prevent cracking, while also helping the product resist water and maintain its texture.
