Science
Mechanism of Action
It functions as a porous, spherical micro-sponge, physically absorbing sebum into its polymer network. Simultaneously, it forms a breathable, flexible film on the skin, enhancing the distribution of pigments and UV filters for a soft-focus, matte aesthetic.

Key findings
- 01 Clinical usage between 0.1% and 14% demonstrates effective oil-absorption and film-forming properties, contributing to a matte finish and improved product longevity.
- 02 Formulations containing 1.0% of similar methacrylate crosspolymers were found to be non-irritating in ocular and dermal clinical safety tests.

The Formula
Formulation
Stability
The crosspolymer structure is highly stable against heat and shear, offering viscosity-building properties. It performs best in near-neutral pH ranges (5.0-8.0), though it exhibits relative pH independence compared to non-crosslinked acrylates.
Conflicts
- High concentrations of electrolytes may impact suspension stability in aqueous systems
- Strongly acidic environments (pH < 4.0) can lead to aggregation or loss of texture
Safety
Safety Profile
The CIR Expert Panel concluded this ingredient is safe when formulated to be non-irritating. Modern cosmetic-grade polymers ensure residual monomers, such as glycidyl methacrylate, are maintained at trace levels (typically <100 ppm).
