How we scored it

Siloxane/silicone (C24-28-alkyl methyl) — silicone family, 0.0 by this site's convention regardless of the alkyl 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 C24-28 alpha-olefins onto a methylhydrogen siloxane derived from silicon metal and methyl chloride. No natural route exists.

In plain English

A silicone emollient that smooths and conditions skin and gives products a silky after-feel. It's made by combining a long fatty chain with a silicone fluid refined from processed silica, not from plants.
