STEARYL METHACRYLATE/PERFLUOROOCTYLETHYL METHACRYLATE COPOLYMER

Description

STEARYL METHACRYLATE/PERFLUOROOCTYLETHYL METHACRYLATE COPOLYMER is a synthetic polymer used in skincare and cosmetic formulations. This ingredient combines the properties of two distinct methacrylate monomers: stearyl methacrylate and perfluorooctylethyl methacrylate. The resulting copolymer offers unique characteristics that make it valuable in various beauty products.

The copolymer functions primarily as a film-forming agent and texture enhancer. It creates a smooth, non-greasy barrier on the skin's surface, which helps to improve product application and longevity. The perfluorinated component contributes water and oil repellency, enhancing the formulation's resistance to environmental factors and sebum.

In skincare, this copolymer is often utilized in foundations, sunscreens, and long-wear cosmetics due to its ability to improve product adherence and durability. It can also contribute to a matte finish, making it particularly useful in formulations designed for oily or combination skin types.

While generally considered safe for cosmetic use, it's important to note that perfluorinated compounds have raised some environmental concerns. Formulators should consider the concentration and overall impact when incorporating this ingredient into their products.
