How we scored it

Cetyl dimethicone, silicone, 0, copolymerised with 10 ethylene oxide + 1 propylene oxide units, petrochemical, 0; both fragments 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

Manufactured by reacting cetyl dimethicone with ethylene oxide and propylene oxide. No natural-origin route exists for either the silicone or the alkoxylate portion.

In plain English

A silicone-based emulsifier that helps blend oil and water phases in creams and cleansers. Made entirely from synthetic silicone and petrochemical building blocks.

CosIng definition: Cetyl PEG/PPG-10/1 Dimethicone is the copolymer of Cetyl Dimethicone and an alkoxylated derivative of Dimethicone containing an average of 10 moles of ethylene oxide and 1 mole of propylene oxide
