INCI: Silica Silylate
Silica silylate is a modified form of amorphous silica produced by reacting silica with trimethylsilane. It functions as a mattifying agent, oil absorber, and thickener in cosmetic formulations. The hydrophobic surface modification allows it to absorb sebum and oil while providing a smooth, powdery skin feel.

Is Silica Silylate safe? Key considerations
Can Silica Silylate cause irritation?
Low RiskSilica silylate is generally well tolerated and non-irritating at typical cosmetic concentrations. No EU CosIng Annex II or III restrictions apply. As a solid particle ingredient, inhalation of loose powder forms should be avoided.
Does Silica Silylate increase sun sensitivity?
No RiskSilica silylate does not increase photosensitivity. No sun protection precautions are required.
Is Silica Silylate safe during pregnancy?
SafeSilica silylate is an inert mineral-derived ingredient with no systemic absorption. No reproductive or developmental concerns are noted in available safety data.
How does Silica Silylate work?
Silica silylate is a modified form of amorphous silica produced by reacting silica with trimethylsilane. It functions as a mattifying agent, oil absorber, and thickener in cosmetic formulations. The hydrophobic surface modification allows it to absorb sebum and oil while providing a smooth, powdery skin feel.
Individuals with very dry skin, inhalation-sensitive individuals (avoid loose powder forms) should review the considerations above before use.
