TRIMETHYLPENTANEDIOL/ISOPHTHALIC ACID/TRIMELLITIC ANHYDRIDE COPOLYMER

Description

Trimethylpentanediol/Isophthalic Acid/Trimellitic Anhydride Copolymer is a synthetic polymer used in various skincare and cosmetic formulations. This complex compound serves primarily as a film-forming agent and viscosity controller. Its molecular structure allows it to create a thin, flexible film on the skin's surface, which can help improve the texture and feel of products while providing a smooth, even application.

In skincare formulations, this copolymer enhances the stability and longevity of other active ingredients by creating a protective barrier. It's particularly useful in water-resistant and long-wearing products such as sunscreens, foundations, and moisturizers. The film-forming properties also contribute to improved skin hydration by reducing transepidermal water loss.

The copolymer is generally considered safe for topical use and is compatible with a wide range of other cosmetic ingredients. It's non-comedogenic, making it suitable for use in products designed for acne-prone skin. While it doesn't have direct skin-benefiting properties like antioxidants or humectants, its role in formulation is crucial for product performance and efficacy. The polymer's ability to enhance product texture and wear time makes it a valuable ingredient in modern skincare and cosmetic formulations.
