POLYETHYLENE/ISOPROPYL MALEATE/MA COPOLYOL

Description

Polyethylene/Isopropyl Maleate/MA Copolyol is a synthetic copolymer used in various skincare and cosmetic formulations. This multifunctional ingredient serves primarily as a film-forming agent and emulsion stabilizer. Its unique chemical structure, combining polyethylene, isopropyl maleate, and maleic anhydride (MA) components, allows it to form a flexible, breathable film on the skin's surface.

This copolymer enhances the texture and feel of products, providing a smooth, non-greasy finish. It aids in improving the spreadability of formulations and can help to distribute other active ingredients more evenly across the skin. In sunscreens, it contributes to water resistance and helps maintain SPF efficacy. The ingredient also acts as a binder in pressed powders and can improve the adherence of pigments in color cosmetics.

Polyethylene/Isopropyl Maleate/MA Copolyol is generally well-tolerated by most skin types. It's particularly useful in long-wearing makeup formulations and products designed for oily or combination skin due to its ability to control shine and improve product longevity. While not an active skincare ingredient itself, it plays a crucial role in enhancing the overall performance and sensory attributes of various cosmetic products.
