How we scored it

Siloxane/silicone (C26-28 alkyl methyl, trimethylsilyl-terminated) — silicone family, 0.0 by this site's convention.
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

Produced by hydrosilylation of a C26-28 alpha-olefin onto a trimethylsilyl-terminated methylhydrogen siloxane, itself made from silicon metal and methyl chloride. No natural-origin route exists.

In plain English

A silicone conditioning agent that forms a smooth, silky film on hair and skin. It's made by combining a long fatty chain with a silicone fluid refined from processed silica; it doesn't come from plants.
