Science
Mechanism of Action
Forms a flexible, water-resistant polymer film on the skin surface that provides structural support to formulations while delivering a smooth, velvet-like tactile experience. The polymer chains create a breathable barrier that helps distribute active ingredients evenly and prevents product migration, particularly enhancing the performance of UV filters in sun protection products.

Dusting Analysis
Functional polymer used at specific concentrations for texture and stability purposes rather than marketing appeal
The Formula
Formulation
Stability
Requires pH neutralization with bases like Tromethamine or NaOH to achieve optimal viscosity and performance. Highly sensitive to electrolyte levels which can cause polymer chain collapse and viscosity loss.
Synergies
- UV filters
- Neutralizing agents (Tromethamine, NaOH)
Conflicts
- High electrolyte concentrations
- Cationic surfactants
- Highly acidic ingredients (pH < 4.5)
Safety
Safety Profile
CIR Expert Panel approval contingent on non-benzene polymerization and residual monomer levels below 0.5 ppm. Excellent safety profile with extensive regulatory acceptance.
