Question 1

What does Dimethicone/Peg-10/15 Crosspolymer do in a cosmetic formula?

Accepted Answer

This ingredient is a crosslinked organosiloxane used as a texture modifier, thickener, oil-phase gel former, and sensory enhancer. It helps give formulas slip, cushion, and a soft-focus finish, especially in emulsions and anhydrous products.

Question 2

Is Dimethicone/Peg-10/15 Crosspolymer clean?

Accepted Answer

Clean-beauty frameworks often flag it because it is a synthetic, non-biodegradable organosiloxane polymer, and some retailer standards restrict this broader material class. Skin tolerance is generally good, so the main friction is environmental persistence and standards alignment rather than irritation.

Question 3

Is Dimethicone/Peg-10/15 Crosspolymer sustainable?

Accepted Answer

This material is synthetic and generally tied to mineral and petrochemical processing rather than renewable feedstocks. It is not readily biodegradable, and rinse-off use has higher environmental-release relevance than leave-on use.

Question 4

Is Dimethicone/Peg-10/15 Crosspolymer COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards because synthetic organosiloxane polymers sit outside the allowed ingredient framework. Its Green Chemistry fit is weak due to non-renewable inputs, limited biodegradability, and persistence concerns.

Question 5

How does Dimethicone/Peg-10/15 Crosspolymer work chemically?

Accepted Answer

The molecule is a three-dimensional crosslinked polysiloxane network with polyether-modified segments, which lets it swell in oils while improving compatibility in emulsion systems. It is commonly used around 0.5% to 10% as supplied, is broadly stable across cosmetic pH ranges, and usually needs adequate shear for smooth dispersion.
