Silica Dimethicone Silylate ●
TL;DR. This ingredient is primarily a rheology modifier and suspending agent, used to thicken oils, gels, and anhydrous systems while improving slip and reducing greasiness.
What does Silica Dimethicone Silylate do in a cosmetic formula?
This ingredient is primarily a rheology modifier and suspending agent, used to thicken oils, gels, and anhydrous systems while improving slip and reducing greasiness.
Is Silica Dimethicone Silylate clean?
From a clean-beauty perspective, it has low irritation potential but is often flagged because it is a synthetic, silicone-modified powder. Many silicone-free and natural-certification frameworks do not accept this material, even when it performs well technically.
Is Silica Dimethicone Silylate sustainable?
This material is based on a mineral-derived particle that has been synthetically surface-treated for water repellency. It is inert and not readily biodegradable, so its sustainability profile is weaker than plant-derived or readily biodegradable thickeners.
Is Silica Dimethicone Silylate COSMOS-approved?
It is not permitted under COSMOS organic or natural standards because of its synthetic organosilicon modification. Its fit with Green Chemistry is limited, with nonrenewable sourcing, low biodegradability, and a surface treatment chosen for performance rather than circularity.
How does Silica Dimethicone Silylate work chemically?
The molecule is an inorganic oxide particle with surface groups capped by organosilicon chains, which makes it hydrophobic and able to build viscosity in nonpolar phases. Typical use is often about 0.5–5%, and it is generally stable in anhydrous systems and across normal cosmetic pH ranges when properly dispersed.
