POLYURETHANE-44

Description

Polyurethane-44 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 various applications. In skincare, Polyurethane-44 functions primarily as a flexible film former, creating a thin, protective layer on the skin or hair surface.

The compound's molecular structure allows it to form a breathable barrier that helps lock in moisture while still permitting oxygen exchange. This characteristic makes it particularly useful in long-wearing makeup products, sunscreens, and hair styling formulas. Polyurethane-44 enhances the adherence of active ingredients to the skin, potentially improving their efficacy and longevity.

Its water-resistant properties contribute to the creation of sweat-proof and transfer-resistant cosmetics, making it a valuable ingredient in products designed for extended wear or use in challenging environmental conditions. Additionally, Polyurethane-44 can improve the texture and spreadability of formulations, contributing to a smooth, even application. While generally considered safe for topical use, as with any synthetic ingredient, patch testing is recommended for individuals with sensitive skin or a history of allergic reactions.
