Science
Mechanism of Action
The ingredient functions through its plate-type crystal architecture which undergoes 'cleavage' and disintegration upon skin contact, significantly reducing friction and providing a smooth, lubricated finish. Additionally, it exerts selective antimicrobial pressure by destabilizing the cellular membranes of P. acnes without disrupting the broader skin microbiome.
Research
Clinical Evidence

Key findings
- 01 Demonstrated selective bactericidal activity against Propionibacterium acnes at concentrations as low as 100 ppm.
- 02 Established as a high-fluidity lubricant in foundation matrices at concentrations reaching 11%.
- 03 Structural analysis confirmed superior lubricity on synthetic skin models via lamellar powder disintegration.
Transparency
Dusting Analysis
Because it shows biological activity against acne-causing bacteria at very low concentrations (100 ppm), it is rarely 'dusted' in the traditional sense; however, in texture-focused formulas, levels below 1% may fail to provide the characteristic lubricity.
The Formula
Formulation
Stability
Possesses low water solubility (0.23 g/L), often behaving as a functional dispersed powder. Highly stable in solid bar formats and anhydrous powder dispersions.
Synergies
- Mineral pigments
- Non-ionic surfactants
- Anionic cleansing agents
Conflicts
- Cationic polymers
- Cationic surfactants
- Strongly acidic environments (pH < 5.0)
Safety
Safety Profile
Validated by the CIR Expert Panel for leave-on use in foundations up to 11%. Formulations should maintain a skin-neutral pH to ensure non-irritating profiles.
