Is Cetyl Behenyl Dimethicone natural?

No. Silicones score 0.0 by this site's convention, so the siloxane chain and the cetyl and behenyl side groups are all counted as non-natural.

How we scored it

Alkyl-modified silicone: this site's convention scores all silicones 0.0 whatever the fatty grafts (cetyl C16, behenyl C22); 0 / total = 0.0.
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 long-chain alpha-olefins (C16 and C22) onto a methylhydrogen siloxane built from silicon metal and methyl chloride. No natural-origin route is commercially significant.

In plain English

A waxy silicone that conditions skin and adds a soft, smooth feel to creams and sticks. It is a dimethicone chain carrying cetyl and behenyl (16- and 22-carbon) fatty groups.
