Polyurethane-15
What Polyurethane-15 is & what it does
Polyurethane-15 is a synthetic film-forming polymer made by reacting polyols with isocyanates. In skincare and sunscreen formulas it forms a flexible, water-resistant film on the skin, which is why it is often used to help products feel long-lasting and resist rub-off. A notable property is that this film can improve the water resistance of sunscreen and the wear of color cosmetics.
