How we scored it

Alkyl(caprylyl)-modified polydimethylsiloxane; this site's convention scores all silicones 0.0 despite the fatty side-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

Manufactured by grafting a caprylyl (C8) side-chain onto a dimethicone backbone via hydrosilylation. This site's convention treats all silicones as 0.0 regardless of any attached natural-type fragment.

In plain English

A silicone-based conditioning ingredient with a short fatty (caprylyl) side-chain attached to a silicone backbone. Used to give skin and hair a smooth, silky feel.
