Science
Mechanism of Action
This ingredient leverages its networked polymer structure to create a stable, protective barrier on the skin's surface. It also effectively thickens water-based systems and stabilizes emulsions by trapping oil droplets.

Key findings
- 01 Human repeated insult patch tests (HRIPT) on 47 subjects demonstrated no signs of irritation or sensitization for acrylates-based copolymers.
- 02 Ocular irritation tests for similar acrylates/vinyl-based crosspolymers showed minimal to no irritation, with resolution within 72 hours if any occurred.

Formulation
Stability
Highly stable across a wide temperature range and resistant to shear forces. It typically requires neutralization (e.g., with TEA or NaOH) to reach maximum viscosity and clarity.
Conflicts
- High electrolyte concentrations
- Strong cationic surfactants
- Extreme acidic conditions (pH < 4.0 may cause precipitation or loss of viscosity)
Safety
Safety Profile
The CIR Expert Panel concluded it is safe when formulated to be non-irritating and not polymerized in benzene. Residual monomer levels are typically restricted below 100 ppm.
