How we scored it

Silicone family (Siloxanes and Silicones, C26-28 alkyl methyl, dimethyl) — this site's convention scores all dimethicones 0.0 regardless of the fatty alkyl pendant chain.
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 by hydrosilylation of a C26-28 fatty alkyl group onto a dimethicone (polydimethylsiloxane) backbone derived from silicon metal and methyl chloride. No alternative natural route exists commercially.

In plain English

A silicone conditioning ingredient that coats hair and skin to make them feel smooth and silky. It's made by attaching a long fatty chain to a liquid silicone backbone; the silicone part comes from processed silica, not plants.
