Science
Mechanism of Action
It functions by creating a three-dimensional network within the water phase, thickening the solution and stabilizing emulsions by 'trapping' oil droplets. Post-application, it forms a thin, non-occlusive film, contributing to a smooth skin feel and supporting moisture retention or environmental protection.

Key findings
- 01 Effectively provides viscosity and stabilizes oil-in-water systems in typical emulsions.
- 02 Tested in aqueous solution on humans, showing no potential for irritation or sensitization.
- 03 Achieves a dynamic viscosity between 47,000 to 77,000 mPa·s at 25°C in aqueous solutions.

The Formula
Formulation
Stability
The polymer requires neutralization with a base (e.g., Sodium Hydroxide) to achieve optimal viscosity. It is stable under normal conditions but sensitive to high electrolyte concentrations.
Conflicts
- High concentrations of electrolytes/salts
- Cationic surfactants
- Strong acids
- Excessive heat during high-shear mixing
Safety
Safety Profile
The 30% maximum concentration typically refers to its capacity to emulsify oil phases, with actual raw ingredient usage generally below 1%. It is safe, provided it is not polymerized in benzene, which is avoided in modern formulations.
