About
A hybrid silica material that acts as an absorbent and oil-control agent in cosmetic formulations, improving skin texture and longevity of makeup.
Caprylylsilsesquioxyzeolite is a hybrid inorganic-organic material produced by reacting triethoxycaprylylsilane with surface silanol groups on zeolite mineral substrates. It combines the oil-absorbing properties of zeolite with the surface-modifying effects of organosilanes, creating a material suitable for sebum absorption and matte-finish cosmetics. Limited specific toxicological data exists for this ingredient in cosmetic contexts, though the individual components (zeolite and organosilanes) have established safety profiles. It is not specifically restricted under EU Regulation 1223/2009, though standard inert filler and absorbent safety assessments apply.
