Science
Mechanism of Action
Upon application, it forms a thin 'mesh' barrier on the skin's surface, stabilizing emulsions and scattering light for a soft-focus effect. This film also locks in moisture, enhances water resistance in sunscreens, and facilitates controlled active ingredient release.

Key findings
- 01 Clinical studies demonstrate efficient delivery of both oil and water-soluble actives at 0.5-5.0%, concurrently improving sensory profiles like 'soft focus' and 'matte'.
- 02 Human Repeated Insult Patch Tests (HRIPT) on related copolymers at up to 25% showed no evidence of dermal irritation or sensitization in leave-on formulations.

Formulation
Stability
The polymer is pH-responsive, typically remaining collapsed below pH 5.5 and elongating with increased viscosity and stability as pH rises. It is commonly supplied as an aqueous emulsion.
Conflicts
- High concentrations of electrolytes (salts) can collapse the polymer structure.
- Very low pH environments (<4.0) may cause precipitation.
Safety
Safety Profile
The CIR Expert Panel concluded this ingredient is safe in current cosmetic practices, provided formulations are non-irritating and residual monomers are strictly controlled below sensitization thresholds.
