POLYURETHANE-75

Description

Polyurethane-75 is a synthetic polymer widely used in cosmetic and skincare formulations for its film-forming and water-resistant properties. This ingredient belongs to the broader family of polyurethanes, which are known for their versatility and durability. In skincare applications, Polyurethane-75 primarily functions as a film former, creating a thin, flexible layer on the skin or hair surface.

The polymer's structure allows it to form a breathable barrier that helps lock in moisture while providing protection against environmental stressors. This characteristic makes it particularly valuable in long-wearing makeup products, sunscreens, and hair styling formulations. Polyurethane-75 exhibits excellent adhesion to the skin and hair, contributing to the longevity and transfer-resistance of products containing it.

Additionally, Polyurethane-75 demonstrates compatibility with a wide range of cosmetic ingredients, enhancing the overall stability and performance of formulations. Its water-resistant properties make it an ideal component in products designed for extended wear or exposure to water. While generally considered safe for topical use, as with any synthetic ingredient, some individuals may experience sensitivity, necessitating patch testing before widespread application.
