POLYURETHANE-57

Description

Polyurethane-57 is a synthetic polymer widely utilized in cosmetic and skincare formulations for its film-forming and water-resistant properties. This ingredient belongs to the family of polyurethanes, known for their versatility and durability in various applications. In skincare products, Polyurethane-57 functions primarily as a film former, creating a thin, flexible layer on the skin or hair surface.

The polymer's structure allows it to form a protective barrier that enhances the longevity of cosmetic products, particularly in water-resistant formulations such as sunscreens, long-wearing makeup, and hair styling products. Polyurethane-57 contributes to improved product adherence to the skin and hair, enabling extended wear time and resistance to water, sweat, and sebum.

Additionally, Polyurethane-57 can enhance the texture and feel of skincare and cosmetic products, providing a smooth, non-tacky finish. Its film-forming capabilities also aid in the even distribution of active ingredients and pigments across the skin surface. While generally considered safe for topical use, as with any synthetic polymer, some individuals may experience sensitivity. It's important to note that Polyurethane-57 is not absorbed by the skin and remains on the surface, acting as a temporary protective coating.
