POLYURETHANE-78

Description

Polyurethane-78 is a synthetic polymer widely used in cosmetic and skincare formulations for its unique film-forming properties. This versatile ingredient belongs to the family of polyurethanes, known for their durability and flexibility. In skincare applications, Polyurethane-78 creates a breathable, non-occlusive barrier on the skin's surface, helping to lock in moisture and protect against environmental stressors.

The molecule's structure allows it to form a smooth, continuous film that adheres well to the skin without feeling heavy or greasy. This characteristic makes it particularly suitable for long-wearing makeup products, sunscreens, and protective skincare formulations. Polyurethane-78 also exhibits good compatibility with a wide range of cosmetic ingredients, enhancing the overall stability and texture of products.

In addition to its protective qualities, Polyurethane-78 can improve the spreadability of formulations, contributing to a more even application of skincare and cosmetic products. Its water-resistant properties make it valuable in swimwear-proof and long-lasting makeup items. 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 to cosmetic products.
