Science
Mechanism of Action
It creates a three-dimensional network in the water phase to trap oil droplets, increasing viscosity in formulations. Upon application, it delivers a soft, 'melting' feel and a protective layer.

Key findings
- 01 A Buehler test on guinea pigs with a related polymer showed no sensitization.
- 02 Ocular and skin irritation assays confirmed minimal to no irritation, supporting its large molecular size prevents skin penetration.
Transparency
Dusting Analysis
This polymer is primarily used for texture and stability enhancement and is not typically associated with 'dusting' in cosmetic formulations.
The Formula
Formulation
Stability
Highly stable under normal conditions but may release ammonia and lose viscosity under strongly alkaline conditions (pH > 9). It is pre-neutralized.
Conflicts
- High concentrations of electrolytes/salts
- Strongly alkaline ingredients
- Strong oxidants
Safety
Safety Profile
The CIR Expert Panel concluded this polymer is safe for current uses, noting its large molecular size prevents skin penetration. Formulators should minimize residual monomers to <5 ppm.
