Science
Mechanism of Action
This ingredient functions as a porous microsponge, effectively absorbing excess oil and sebum from the skin's surface to minimize shine and help prevent clogged pores. Its hydrophobic nature, achieved through surface modification, allows it to stabilize oil-based products, thicken oils and polyols, and impart a luxurious, lightweight texture. It also aids in the uniform dispersion of other cosmetic ingredients.

The Formula
Formulation
Stability
Silica Caprylyl Silylate is a hydrophobic derivative of fumed silica, coated with polycaprylylsilsesquioxane, rendering it water-repellent. This modification enhances its stability in oil-based formulations and makes it insoluble in water and most organic solvents.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel considers Silica Silylate, a closely related compound, safe for cosmetic use when formulated to avoid respiratory irritation. Reported use concentrations for this class of ingredients typically range from 0.2% to 25%. The European Commission's SCCS notes that if more than 50% of particles are below 100 nanometers, it may require 'nanomaterial' labeling, though a definitive safety decision on nano-form Synthetic Amorphous Silica was not made in 2015 due to insufficient evidence.
