POLYURETHANE-45

Description

Polyurethane-45 is a synthetic polymer widely used in cosmetic and skincare formulations. This versatile ingredient functions primarily as a film-forming agent, providing a protective barrier on the skin's surface. Its unique chemical structure allows it to create a flexible, breathable film that helps to lock in moisture and protect against environmental stressors.

In skincare products, Polyurethane-45 is valued for its ability to improve texture and enhance the overall feel of formulations. It contributes to smoother application and helps products adhere better to the skin, potentially increasing their longevity and effectiveness. This polymer is particularly useful in long-wearing makeup products, such as foundations and mascaras, where it helps to prevent smudging and transfer.

Polyurethane-45 is generally well-tolerated by most skin types and is considered safe for use in cosmetic applications. It is non-comedogenic, meaning it does not clog pores, making it suitable for use in products designed for acne-prone skin. Additionally, this ingredient can enhance the water resistance of sunscreens and other protective formulations, contributing to more effective sun protection and longer-lasting wear in humid or aquatic environments.
