Science
Mechanism of Action
It forms a cohesive, non-sticky polymeric film, acting as a physical shield against environmental pollutants. This polymeric network also modifies rheology, stabilizing emulsions and supporting active delivery.

Key findings
- 01 Formulations with 2.0% effectively reduced particulate matter adhesion, protecting the skin barrier from pollution.
- 02 In vivo testing showed 5.0% created a uniform, flexible film, supporting active delivery and structural integrity in peel-off masks.

The Formula
Formulation
Stability
Supplied as a low-viscosity emulsion, it requires neutralization (e.g., AMP or NaOH) to achieve desired thickening and clarity. It is stable in the presence of various electrolytes.
Conflicts
- High concentrations of strong electrolytes (can reduce viscosity)
- Very low pH environments (below 5.0 causes precipitation)
- Strong cationic surfactants (may cause complexation)
Safety
Safety Profile
The 2022 CIR Expert Panel deemed it safe, provided residual acrylamide monomer is controlled below 5 ppm in final formulations.
