Science
Mechanism of Action
Upon application, the polymer dries to form a continuous, cohesive film. In skincare, it offers a temporary tightening sensation and reduces formula tackiness, while in hair care, it provides hold and gloss by coating the hair shaft.

The Formula
Formulation
Stability
This anionic aqueous solution, neutralized by AMP, is miscible with both water and ethanol. It maintains stability in high-humidity environments.
Conflicts
- Cationic surfactants (due to its anionic nature)
- Strong acids (may cause precipitation)
- Nitrosating agents (due to secondary amine concerns)
Safety
Safety Profile
The CIR Expert Panel concluded it is safe when non-irritating and residual acrylamide monomer is below 5 ppm. EU Annex III restricts its use due to potential nitrosamine formation.
