Science
Mechanism of Action
Functions as microscopic ball-bearing spheres that reduce friction during application while improving product spreadability. The porous structure effectively scatters light to create optical blurring effects and absorbs excess sebum for mattification, while providing gentle physical exfoliation when used in cleansing products.

Dusting Analysis
Rarely appears in trace amounts due to its specific functional role as a sensory modifier and the relatively high concentrations needed for effectiveness
The Formula
Formulation
Stability
Hydrophobically modified polymer stable in both oil-in-water and water-in-oil emulsions. Must be incorporated below 60°C during cooling phase to preserve microsphere integrity and prevent thermal degradation.
Synergies
- Silicone powders
- Mica particles
- Zinc oxide
Conflicts
- Strong oxidizing agents
- Formulations above pH 9.0
Safety
Safety Profile
Considered safe due to biocompatibility and the fact that component monomers are natural human metabolites. Complies with EU REACH microplastic regulations as readily biodegradable material.
