PHTHALIC ANHYDRIDE/BENZOIC ACID/TRIMETHYLOLPROPANE COPOLYMER

Description

Phthalic Anhydride/Benzoic Acid/Trimethylolpropane Copolymer is a synthetic polymer used in cosmetic and skincare formulations. This ingredient functions primarily as a film-forming agent and viscosity controller, contributing to the texture and stability of various products.

The copolymer is created through the condensation of phthalic anhydride, benzoic acid, and trimethylolpropane. Its structure allows it to form a flexible, breathable film on the skin's surface, which can help improve the longevity of makeup and provide a smooth, even application. In skincare products, it aids in creating a protective barrier that can help retain moisture and protect against environmental stressors.

This ingredient is particularly useful in formulations such as foundations, primers, and long-wearing cosmetics due to its ability to enhance product adhesion to the skin. It also contributes to the water-resistance of sunscreens and other protective formulations. The copolymer is generally considered safe for use in cosmetics, with low risk of skin irritation or sensitization.

When incorporated into skincare products, Phthalic Anhydride/Benzoic Acid/Trimethylolpropane Copolymer can improve the overall feel and performance, offering benefits in terms of product stability, application, and wear time.
