PHTHALIC ANHYDRIDE/ADIPIC ACID/CASTOR OIL/NEOPENTYL GLYCOL/PEG-3/TRIMETHYLOLPROPANE COPOLYMER

Description

Phthalic Anhydride/Adipic Acid/Castor Oil/Neopentyl Glycol/PEG-3/Trimethylolpropane Copolymer is a complex synthetic polymer used in various cosmetic and skincare formulations. This multifaceted ingredient functions primarily as a film-forming agent and viscosity controller, contributing to the texture and stability of products.

The copolymer's unique structure, combining both hydrophobic and hydrophilic components, allows it to form a flexible, breathable film on the skin's surface. This film helps to lock in moisture, improve product adherence, and provide a smooth, non-greasy finish. Its film-forming properties make it particularly useful in long-wearing makeup formulations and sunscreens.

As a viscosity controller, it helps stabilize emulsions and suspensions, ensuring consistent product texture and performance over time. The ingredient is generally considered safe for topical use and is compatible with a wide range of other cosmetic ingredients.

In skincare, this copolymer can enhance the spreadability of formulations and contribute to a silky feel upon application. It's often used in products designed to provide a matte finish or oil control benefits. While not actively addressing specific skin concerns, its functional properties support the overall efficacy and sensory experience of various skincare and cosmetic products.
