Question 1

What does Dimethiconol/Propylsilsesquioxane/Silicate Crosspolymer do in a cosmetic formula?

Accepted Answer

This ingredient is a synthetic film-former and texture modifier used to improve slip, adhesion, water resistance, and soft-focus payoff in makeup, sunscreen, and hair products.

Question 2

Is Dimethiconol/Propylsilsesquioxane/Silicate Crosspolymer clean?

Accepted Answer

From a clean-beauty perspective, it is usually flagged because it is a persistent synthetic polymer rather than because of high irritation potential. It is generally well tolerated on skin, but many stricter clean standards restrict or exclude this class of materials.

Question 3

Is Dimethiconol/Propylsilsesquioxane/Silicate Crosspolymer sustainable?

Accepted Answer

This material is made through synthetic silicon-based chemistry, with organic groups typically derived from petrochemical feedstocks. It is not readily biodegradable and can persist in wastewater sludge or sediment after use.

Question 4

Is Dimethiconol/Propylsilsesquioxane/Silicate Crosspolymer COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards as a conventional synthetic silicon-based polymer. Its persistence and non-renewable feedstock profile make it a poor fit with Green Chemistry priorities such as biodegradability and renewable sourcing.

Question 5

How does Dimethiconol/Propylsilsesquioxane/Silicate Crosspolymer work chemically?

Accepted Answer

The molecule is a crosslinked silicon-oxygen polymer network with organic side groups, giving it high molecular weight, low water solubility, and strong film integrity. It is typically supplied as a dispersion or gel in carriers, remains stable across normal cosmetic pH ranges, and is mainly chosen for sensory finish, film strength, and water-resistance support.
