Caprylylsilsesquioxane/Silicate Crosspolymer ●
TL;DR. This ingredient is used as a film-former, texture modifier, and soft-focus powder in makeup, sunscreen, and skin-care formulas. It can improve slip, water resistance, oil control, and pigment dispersion.
What does Caprylylsilsesquioxane/Silicate Crosspolymer do in a cosmetic formula?
This ingredient is used as a film-former, texture modifier, and soft-focus powder in makeup, sunscreen, and skin-care formulas. It can improve slip, water resistance, oil control, and pigment dispersion.
Is Caprylylsilsesquioxane/Silicate Crosspolymer clean?
From a clean-beauty perspective, it is usually flagged because it is a synthetic organosilicon polymer with limited biodegradability and frequent clean-retailer restrictions. Skin irritation is generally low, so the main friction is environmental persistence rather than direct tolerance.
Is Caprylylsilsesquioxane/Silicate Crosspolymer sustainable?
This material is made from mineral and petrochemical inputs through synthetic polymer chemistry. It is not readily biodegradable and is expected to persist as an inert particulate polymer after rinse-off or disposal.
Is Caprylylsilsesquioxane/Silicate Crosspolymer COSMOS-approved?
It is not permitted under COSMOS organic or natural standards because this type of synthetic organosilicon polymer falls outside the allowed ingredient set. Its Green Chemistry fit is weak due to non-renewable feedstocks, limited biodegradability, and specialized synthetic processing.
How does Caprylylsilsesquioxane/Silicate Crosspolymer work chemically?
The molecule is a crosslinked inorganic-organic network with silicate units, alkyl substitution, and a rigid resin-like architecture that gives a dry, powdery sensory profile. It is typically used at low single-digit to mid-single-digit percentages, is broadly pH-stable in finished emulsions and anhydrous systems, and is often paired with emollients, pigments, and UV filters to improve spread and film integrity.
