How we scored it

Silicone backbone (dimethicone) + PEG-7 ethoxylate chain; this site's convention scores all silicones 0.0 regardless of PEG content.
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

Made from dimethylsiloxane reacted with polyethylene glycol (ethylene oxide); both are petrochemical/mineral-processed industrial feedstocks. No natural-origin route exists commercially.

In plain English

A silicone conditioning ingredient that smooths hair and skin and helps products spread easily. It's made industrially from silicone polymer combined with a small amount of polyethylene glycol; no plant or animal source is involved.
