ADIPIC ACID/NEOPENTYL GLYCOL/TRIMELLITIC ANHYDRIDE COPOLYMER

Description

Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer is a synthetic polymer widely used in cosmetic and skincare formulations. This ingredient functions primarily as a film-forming agent and viscosity controller, providing texture and stability to various products. The copolymer is composed of three key components: adipic acid, neopentyl glycol, and trimellitic anhydride, which combine to create a versatile compound with multiple benefits.

In skincare applications, this copolymer forms a protective barrier on the skin's surface, helping to lock in moisture and prevent transepidermal water loss. It also contributes to the smooth application and even distribution of active ingredients in formulations. The film-forming properties of this ingredient make it particularly useful in long-wearing makeup products, such as foundations and mascaras, where it enhances product adherence and longevity.

The copolymer is generally considered safe for use in cosmetics and is compatible with a wide range of other ingredients. It is non-comedogenic, meaning it does not clog pores, making it suitable for various skin types. While it primarily serves functional purposes in formulations, it indirectly contributes to skin health by improving product performance and stability.
