BIS-VINYLDIMETHICONE/DIMETHICONE COPOLYMER ●
TL;DR. This ingredient is a texture modifier, film-former, and oil-phase thickener that gives products a soft, velvety feel. It is often used for blurring, slip, and reducing greasy finish in primers, sunscreens, and makeup.
What does BIS-VINYLDIMETHICONE/DIMETHICONE COPOLYMER do in a cosmetic formula?
This ingredient is a texture modifier, film-former, and oil-phase thickener that gives products a soft, velvety feel. It is often used for blurring, slip, and reducing greasy finish in primers, sunscreens, and makeup.
Is BIS-VINYLDIMETHICONE/DIMETHICONE COPOLYMER clean?
From a clean-beauty perspective, it is usually flagged because it is a synthetic, non-biodegradable polymer rather than because of high irritation potential. It is generally well tolerated on skin, but it has friction with standards that limit persistent synthetic polymers.
Is BIS-VINYLDIMETHICONE/DIMETHICONE COPOLYMER sustainable?
This material is synthetic and typically relies on mineral-derived silicon chemistry plus petrochemical inputs. It is not readily biodegradable, so its environmental profile is weaker than plant-derived or readily degradable texture agents.
Is BIS-VINYLDIMETHICONE/DIMETHICONE COPOLYMER COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its Green Chemistry fit is limited because it is persistent, synthetic, and not based on renewable feedstocks.
How does BIS-VINYLDIMETHICONE/DIMETHICONE COPOLYMER work chemically?
The molecule is a crosslinked organosilicon polymer with a flexible silicon-oxygen backbone and organic side groups, which creates an elastic network that swells in compatible oils. It is chemically stable across typical cosmetic pH ranges and is used as a dispersed gel or powder-like elastomer to build viscosity, improve spread, and reduce tack.
