ACRYLIC ACID/METHACRYLAMIDOPROPYLTRIMONIUM CHLORIDE COPOLYMER.

Valuable / HAIR CONDITIONING

ACRYLIC ACID/METHACRYLAMIDOPROPYLTRIMONIUM CHLORIDE COPOLYMER is a cationic polymer engineered to enhance the sensorial and functional properties of cosmetic formulations. It forms a smooth, uniform film on skin and hair, providing significant conditioning and moisture-retaining benefits.

Summary

Hair Conditioning Film-forming Conditioning Moisture Retention Thickening Agent

Science

Mechanism of Action

As a positively charged cationic polymer, ACRYLIC ACID/METHACRYLAMIDOPROPYLTRIMONIUM CHLORIDE COPOLYMER electrostatically binds to the negatively charged surface of skin and hair. This interaction creates a protective and smooth film, delivering conditioning, improving softness, aiding in moisture retention, and contributing to the thickening of the overall formula.
