Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer
Description
Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer is a synthetic film-forming agent widely used in cosmetic and skincare formulations. This complex polymer is created through the polymerization of adipic acid, neopentyl glycol, and trimellitic anhydride. Its primary function is to provide a protective barrier on the skin or hair, enhancing product longevity and performance.
The copolymer exhibits excellent adhesion properties, allowing it to form a flexible, breathable film that helps lock in moisture and active ingredients. This characteristic makes it particularly valuable in long-wearing makeup products, sunscreens, and hair styling formulations. The film it creates is resistant to water and sebum, contributing to improved product durability and wear time.
In skincare applications, this copolymer can help stabilize emulsions and suspend particles, leading to better product consistency and texture. It also contributes to a smooth, non-tacky feel upon application. The ingredient is generally considered safe for use in cosmetics and is non-comedogenic, making it suitable for a wide range of skin types.
While effective, formulators should consider potential interactions with other ingredients and conduct stability tests to ensure optimal performance in final products.
