BUTYL ESTER OF ETHYLENE/MA COPOLYMER
Description
Butyl Ester of Ethylene/MA Copolymer is a synthetic polymer derived from the esterification of ethylene/maleic anhydride copolymer with butyl alcohol. This versatile ingredient serves multiple functions in skincare and cosmetic formulations, primarily as a film-forming agent and viscosity controller.
The copolymer creates a thin, flexible film on the skin's surface, which helps to improve the texture and feel of products while providing a protective barrier. This film-forming property is particularly beneficial in long-wearing makeup formulations and sunscreens, enhancing their durability and water resistance.
As a viscosity controller, it helps stabilize emulsions and suspensions, ensuring consistent product texture and preventing separation of ingredients. This characteristic is crucial for maintaining the integrity and shelf-life of various skincare products.
The Butyl Ester of Ethylene/MA Copolymer is generally well-tolerated by most skin types and is considered safe for use in cosmetics. Its low potential for skin irritation makes it suitable for inclusion in a wide range of formulations, from lightweight serums to rich creams. However, as with any ingredient, individual sensitivities may vary, and patch testing is recommended for those with particularly sensitive skin.
