Is Lauryl PEG-10 Tris(Trimethylsiloxy)Silylethyl Dimethicone natural?

No. All silicones score 0.0 by this site's convention; the lauryl graft is natural but not credited, and the PEG-10 chain is petrochemical ethylene oxide.

How we scored it

Silicone: 0.0 by this site's convention, including the lauryl graft; PEG-10 part is petrochemical ethylene oxide anyway.
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

Dominant route hydrosilylation grafts lauryl and PEG chains onto a siloxane backbone made from silicon metal and methyl chloride. No natural-origin variant exists.

In plain English

A silicone-based emulsifier that lets water and oil or silicone phases mix, used in makeup and sunscreen. It is a fully synthetic polymer with polyethylene glycol and lauryl side chains.

CosIng definition: Lauryl PEG-10 Tris(Trimethylsiloxy)silylethyl Dimethicone is the silicone compound
