Silica Caprylyl Silylate ●
TL;DR. It is a hydrophobic oil-absorbing powder used to thicken, mattify, improve slip, and help suspend pigments or actives in anhydrous and emulsion formulas.
What does Silica Caprylyl Silylate do in a cosmetic formula?
It is a hydrophobic oil-absorbing powder used to thicken, mattify, improve slip, and help suspend pigments or actives in anhydrous and emulsion formulas.
Is Silica Caprylyl Silylate clean?
It is generally low-irritation on skin, with the main clean-standard caveat being airborne exposure in loose or sprayable fine-powder formats. Its synthetic surface treatment creates more natural-standard friction than simple mineral powders.
Is Silica Caprylyl Silylate sustainable?
It is made from an abundant mineral substrate that is chemically modified with synthetic C8 silane chemistry, so sourcing is generally not tied to agricultural land-use pressure. It is inert and not expected to bioaccumulate, but the mineral particle portion does not biodegrade like organic ingredients do.
Is Silica Caprylyl Silylate COSMOS-approved?
It is not a straightforward fit for COSMOS-organic or COSMOS-natural because it is a chemically surface-treated mineral rather than a simple permitted mineral powder. Green Chemistry alignment is mixed: abundant mineral base and low reactivity, but synthetic organosilicon processing and limited biodegradability.
How does Silica Caprylyl Silylate work chemically?
The material is an amorphous high-surface-area mineral particle whose surface hydroxyl groups are capped with C8 alkyl-silyl groups, which makes it strongly water-repelling and oil-compatible. It is typically used at low single-digit levels for texture and oil control, is broadly pH-stable, and performs best when well dispersed to prevent clumping.
