How we scored it

Dimethicone (silicone) backbone with EO/PO side chains. This site's convention: all silicones = 0.0 regardless of ethoxylation/propoxylation.
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

Manufactured by reacting silicone (dimethicone) with ethylene oxide and propylene oxide. Treated as entirely synthetic by this site's convention.

In plain English

A silicone (dimethicone) modified with ethylene oxide and propylene oxide, both petroleum-derived. Used to prevent caking and help blend oil and water.

CosIng definition: Siloxanes and silicones, dimethyl, 3-hydroxypropyl methyl, ethoxylated, propoxylated (15 mol EO, 5 mol PO average molar ratio)
