Science
Mechanism of Action
The polymer swells significantly in water, creating a robust 3D network that increases viscosity and stabilizes emulsions. It also forms a non-greasy film on the skin, reducing transepidermal water loss and imparting a silky feel.

Key findings
- 01 Concentrations from 0.5% to 5.0% demonstrate concentration-dependent rheological improvement. A 3.0% concentration specifically yields stable emulsion gels with self-gelling properties and high elasticity, suitable for advanced topical formulations.

The Formula
Formulation
Stability
Stable across a wide pH range, this polymer is sensitive to high electrolyte or salt concentrations which can compromise its viscosity and network integrity. It is often supplied as a pre-neutralized liquid dispersion.
Conflicts
- High concentrations of electrolytes/salts (e.g., Sodium Chloride)
- Strong oxidants
- Cationic surfactants or polymers
Safety
Safety Profile
Safety hinges on residual acrylamide monomer levels not exceeding 5 ppm in the final product. EU regulations restrict residual monomer to 0.1 mg/kg for leave-on products and 0.5 mg/kg for others.
