Is Cetearyl Dimethicone natural?

No. A silicone (Si-O backbone) ingredient; this site's convention rates all silicones 0.0 despite the fatty cetearyl modification.

How we scored it

A dimethicone (silicone) modified with cetearyl fatty groups; this site's convention scores all silicones 0.0 regardless of organic side-groups. 0/MW = 0.00.
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 petrochemically from dimethylsiloxane, then modified with cetearyl (fatty alcohol) side-groups. No natural-origin route exists for the silicone backbone.

In plain English

A silicone-based emollient modified with fatty groups to feel richer on skin. Despite the fatty part, it's still fundamentally a silicone made from petrochemical feedstock.
