Question 1

What does Vinyldimethyl/ Trimethylsiloxysilicate/ Dimethicone Crosspolymer do in a cosmetic formula?

Accepted Answer

It acts as an elastomeric texture modifier and film-former, giving slip, soft-focus blurring, water resistance, and a flexible, powdery feel in creams, primers, and color cosmetics.

Question 2

Is Vinyldimethyl/ Trimethylsiloxysilicate/ Dimethicone Crosspolymer clean?

Accepted Answer

Clean frameworks often flag this material because it is a synthetic, non-biodegradable film-former rather than a skin-biology active, and some retailers restrict related materials. Skin irritation is typically low, but the main scrutiny is persistence and residual cyclic impurities from manufacturing.

Question 3

Is Vinyldimethyl/ Trimethylsiloxysilicate/ Dimethicone Crosspolymer sustainable?

Accepted Answer

It is made from mineral-derived silicon chemistry and petrochemical methyl or vinyl inputs, so it is not renewable. It is expected to be poorly biodegradable and may persist in waterways and sediment, although its high molecular weight limits skin penetration.

Question 4

Is Vinyldimethyl/ Trimethylsiloxysilicate/ Dimethicone Crosspolymer COSMOS-approved?

Accepted Answer

It is not permitted in COSMOS-natural or COSMOS-organic formulas because the standard does not allow this type of synthetic organosilicon polymer. Its Green Chemistry fit is weak, with nonrenewable feedstocks, limited biodegradability, and energy-intensive synthesis outweighing its low use-level performance benefits.

Question 5

How does Vinyldimethyl/ Trimethylsiloxysilicate/ Dimethicone Crosspolymer work chemically?

Accepted Answer

This material is a crosslinked network with Si-O backbones and methyl or vinyl substitution, supplied as a swellable elastomer or dispersed powder depending on the carrier. It is generally used around 0.5 to 10% for sensory modification and film formation, is broadly pH-stable in anhydrous and emulsion systems, and requires good dispersion or pre-swelling for uniform feel.
