How we scored it

Silicone polymer (dimethyl/alkylmethyl siloxane); this site's convention scores all silicones 0.0 regardless of Si-O mineral origin.
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 silicone fluid reacted with a long C20-24 alkyl chain via petrochemical hydrosilylation. No natural-origin alternative route exists commercially.

In plain English

A silicone-based conditioning and thickening ingredient with a long fatty side-chain. It behaves like a silky silicone on skin and hair, not like a plant oil.
