Science
Mechanism of Action
The copolymer contains secondary and tertiary amine groups that become protonated at lower pH, developing a cationic charge. This allows it to anchor to negatively charged keratin surfaces, forming a continuous, protective film that reduces static and improves hydration.

Key findings
- 01 Studies indicate effective use between 0.5% and 5.0% for conditioning and anchoring on keratin surfaces, with 1.0% to 2.0% being optimal for effective precipitation.
- 02 A broad range of 0.001% to 25.0% is cited for general cosmetic compositions to enhance moisture retention and feel while reducing irritation.
