POLYMETHACRYLIC ACID

Safety grade: A

This is a synthetic polymer—essentially a chain of tiny molecules linked together—that creates a thin, flexible coating. It's commonly used in skincare and cosmetic products to help them feel smooth and hold their shape.

It acts as a binder that forms a protective film on the skin or product surface while also thickening the formula to achieve the desired consistency and texture.
