Science
Mechanism of Action
It operates via associative thickening, forming a structured network through hydrophobic and hydrophilic interactions within the formula. This effectively increases viscosity and enhances overall formula stability.

The Formula
Formulation
Stability
As an anionic polymer, neutralization with a base (e.g., Sodium Hydroxide) is typically required to activate maximum viscosity. It maintains stability across a wide pH range post-neutralization.
Conflicts
- Cationic surfactants
- High electrolyte/salt concentrations
- Polyvalent cations (e.g., Calcium, Magnesium)
Safety
Safety Profile
Though not CIR-reviewed individually, its large molecular weight, typical of acrylate polymers, prevents skin penetration, suggesting general safety. It is listed in EU CosIng without concentration limits.
