How we scored it

Amodimethicone silicone backbone (0.0, this site's convention) ethoxylated with 7 mol PEG (petrochemical ethylene oxide); both fragments petrochemical, so the whole molecule is 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

Manufactured by reacting a silicone (amodimethicone) with ethylene oxide to attach PEG-7 side chains. No natural-origin route exists for either the silicone or the PEG fragment.

In plain English

A conditioning silicone used in hair care to smooth and detangle, modified with a water-loving PEG chain. Entirely a manufactured, petroleum-derived ingredient, not plant-based.
