POLYACRYLIC ACID

Safety grade: A

Polyacrylic acid is a synthetic polymer (a chain of molecules linked together) that acts like a thickener and stabilizer in cosmetic products. It helps keep ingredients mixed together and creates a smooth, spreadable texture.

This ingredient thickens products, helps oil and water stay blended together, creates a protective layer on skin or hair, and controls how thick or thin a cosmetic product feels.
