Question 1

What does Dimethicone/Vinyl Diphenyl Dimethicone/Silsesquioxane Crosspolymer do in a cosmetic formula?

Accepted Answer

This ingredient is used as a sensory modifier and blurring agent, adding slip, cushion, soft-focus effects, and a powdery finish to skin care, makeup, and hair products. It also helps thicken anhydrous formulas and improve product spread.

Question 2

Is Dimethicone/Vinyl Diphenyl Dimethicone/Silsesquioxane Crosspolymer clean?

Accepted Answer

From a clean-beauty perspective, this material has friction because it is a non-biodegradable synthetic polymer rather than because of common irritation concerns. It is generally well tolerated on skin, but clean standards may restrict it due to persistence and residual-monomer scrutiny.

Question 3

Is Dimethicone/Vinyl Diphenyl Dimethicone/Silsesquioxane Crosspolymer sustainable?

Accepted Answer

This ingredient is synthetic and typically derived from mineral and petrochemical feedstocks. It is not readily biodegradable and can persist after rinse-off use, which weakens its environmental profile.

Question 4

Is Dimethicone/Vinyl Diphenyl Dimethicone/Silsesquioxane Crosspolymer COSMOS-approved?

Accepted Answer

This ingredient is not permitted under COSMOS-natural or COSMOS-organic standards. It has weak Green Chemistry alignment because it relies on synthetic polymer chemistry, limited biodegradability, and non-renewable feedstocks, despite being chemically stable and useful at low levels.

Question 5

How does Dimethicone/Vinyl Diphenyl Dimethicone/Silsesquioxane Crosspolymer work chemically?

Accepted Answer

This material is a crosslinked, high-molecular-weight silicon-oxygen polymer network designed to swell or disperse in compatible oils while creating an elastomeric feel. It is typically used at low single-digit percentages, is stable across normal cosmetic pH ranges, and is mainly a physical texture modifier rather than a reactive ingredient.
