How we scored it

Dimethicone/siloxane backbone (0.0 by convention) with PEG-9 side chain (petrochemical ethylene oxide); overall 0.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

A silicone copolymer built from a polydimethylsiloxane backbone with a polyethylene glycol side chain, both petrochemical in feedstock. The silicone portion is also scored 0.0 by this site's convention.

In plain English

A silicone-based emulsifier used to blend water and oil and condition skin. Combines a silicone backbone with a synthetic PEG side chain.

CosIng definition: Siloxanes and silicones, dimethyl, 3-(hydropoly(oxy-1,2-ethanediyl)propyl methyl, 2-(trimethylsilyloxydimethylsilyl)ethyl methyl, trimethyl terminated (9 mol EO average molar ratio)
