Trimethylsiloxysilicate/Dimethiconol Crosspolymer ●
TL;DR. This ingredient is primarily a film-former and texture modifier, used to improve wear, water resistance, transfer resistance, and slip in makeup, sunscreen, and hair styling formulas.
What does Trimethylsiloxysilicate/Dimethiconol Crosspolymer do in a cosmetic formula?
This ingredient is primarily a film-former and texture modifier, used to improve wear, water resistance, transfer resistance, and slip in makeup, sunscreen, and hair styling formulas.
Is Trimethylsiloxysilicate/Dimethiconol Crosspolymer clean?
It is generally low-irritation on skin, but it has clean-standard friction because it is a synthetic, non-biodegradable silicon-based polymer. Many stricter clean frameworks flag this material for persistence rather than direct skin tolerance concerns.
Is Trimethylsiloxysilicate/Dimethiconol Crosspolymer sustainable?
This material is made from non-renewable mineral and petrochemical feedstocks through energy-intensive processing. It is not readily biodegradable, and its high molecular weight lowers mobility but does not remove persistence concerns.
Is Trimethylsiloxysilicate/Dimethiconol Crosspolymer COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its Green Chemistry fit is weak because it is synthetic, non-renewable, and persistent, even though it is typically inert in finished formulas.
How does Trimethylsiloxysilicate/Dimethiconol Crosspolymer work chemically?
The molecule is a crosslinked silicon-oxygen polymer network that forms flexible, glossy, water-repellent films as carrier fluids evaporate or spread. It is water-insoluble, broadly pH-stable in typical cosmetic ranges, and commonly used at low single-digit to around 10% active levels depending on the desired film strength and feel.
