Polyurethanes are polymers or copolymers based on diisocyanates and dialcohols (diols). Polyurethanes contain the urethane group -NH-CO-O-. Linear polyurethanes are obtained from aliphatic glycols and aliphatic diisocyanates. Crosslinked insoluble polyurethanes are obtained from substances with more than 2 hydroxyl groups.

Polyurethane-1 is used in cosmetics. They act as binders (ensures the cohesion of powdery and powdery products) and as film formers (forms a film on skin, hair or nails when applied).
