Science
Mechanism of Action
Upon application, the copolymer particles coalesce as volatile carriers evaporate, creating a thin, water-resistant film. This film provides structural integrity to products, improves pigment adhesion, and physically smooths the skin.

Formulation
Stability
Typically supplied as an aqueous dispersion, it is stable across its pH range, with optimal film formation at pH 6.0-7.5. Avoid prolonged exposure to temperatures above 45°C.
Conflicts
- High concentrations of electrolytes/salts (risk of emulsion instability)
- Cationic surfactants (may cause polymer precipitation)
Safety
Safety Profile
While not CIR-reviewed as a complex copolymer, its constituent monomers are well-characterized. Sensitization risk from HEMA is significantly reduced in its polymerized form; generally considered safe for use.
