Science
Mechanism of Action
It functions as a cross-linked polymer that swells in water, forming a 3D network to increase viscosity and stabilize oil-in-water emulsions. This polymer also forms a skin surface film, reducing TEWL for improved hydration.

Key findings
- 01 Effective in 0.5% - 1.2% concentrations for stable, clear gel textures with good spreadability and non-tacky feel.
- 02 CIR confirmed non-respirable and non-toxic for incidental inhalation up to 3.0%.

The Formula
Formulation
Stability
Pre-neutralized for cold processing, this polymer maintains high transparency in aqueous gels. High electrolyte concentrations can significantly reduce its viscosity.
Conflicts
- Electrolytes (Sodium Chloride, Magnesium Sulfate)
- High concentrations of alpha-hydroxy acids (due to low pH/ionic load)
- Cationic surfactants
Safety
Safety Profile
The CIR Expert Panel found it safe for use, emphasizing the need to keep residual monomers (vinyl formamide, acrylamide) below 5 ppm.
