POLYURETHANE-70

Description

Polyurethane-70 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 form a flexible, breathable film that helps to lock in moisture and protect against environmental stressors.

In skincare products, Polyurethane-70 enhances the texture and feel of formulations, contributing to a smooth, non-sticky finish. It is particularly effective in long-wear makeup products, such as foundations and mascaras, where it improves adherence and water resistance. The polymer also aids in the even distribution of active ingredients across the skin's surface, potentially improving their efficacy.

Polyurethane-70 is generally well-tolerated by most skin types and is considered safe for use in cosmetic applications. Its molecular weight is typically too large to penetrate the skin, minimizing the risk of irritation or systemic absorption. This ingredient is often found in combination with other film-formers and emollients to create multi-functional skincare and makeup products that offer both protective and aesthetic benefits.
