Science
Mechanism of Action
Upon application, the polymer dries to form a continuous, flexible, and clear film. This film creates a moisture barrier and provides structural hold by binding to keratinous surfaces, supporting long-wear cosmetic applications.

The Formula
Formulation
Stability
Highly stable once the film is formed, particularly under high humidity and temperature. It is soluble in alcohol and water/alcohol mixtures, with stability optimized by neutralization with AMPD.
Conflicts
- Strong oxidizing agents
- Nitrosating agents (due to risk of nitrosamine formation)
- Strongly acidic environments
Safety
Safety Profile
Safety is contingent on limiting residual acrylamide monomer to below 2 ppm and ensuring non-irritating formulations. It is restricted in the EU under Annex III due to potential nitrosamine formation in the presence of nitrosating agents.
