How we scored it

Dimethicone backbone = 0 (this site's convention); EO/PPG chains (20+20 mol) = 0 (petrochemical). 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 (dimethicone) backbone is modified with petrochemical ethylene oxide and propylene oxide side chains. Both the backbone and the added chains are non-renewable by composition and this site's convention.

In plain English

A silicone-based emulsifier that helps blend water and oil in creams and lotions. It is built from a man-made silicone chain combined with petrochemical ingredients, not from plants or minerals.

CosIng definition: Siloxanes and silicones, dimethyl, 3-hydroxypropyl methyl, ethoxylated, propoxylated (20 mol EO, 20 mol PO average molar ratio)
