Is Lauryl Dimethicone PEG-15 Crosspolymer natural?

No. The silicone backbone is 0.0 by convention, PEG-15 comes from ethylene oxide, and silicones stay 0.0 whatever their fatty side chains.

How we scored it

Silicone crosspolymer: 0.0 by this site's convention; PEG-15 chains are petrochemical (ethylene oxide) and the lauryl graft is not credited on a silicone.
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

Hydrosilylation crosslinking of a methyl hydrogen siloxane with vinyl-functional PEG-15 and lauryl groups, on a silicone from methylchlorosilanes. No significant natural route exists.

In plain English

A cross-linked silicone elastomer carrying PEG-15 and lauryl side chains. It thickens and gives a silky texture to creams and helps oil and water phases emulsify. It is synthetic; the PEG part comes from petrochemical ethylene oxide.

CosIng definition: Lauryl Dimethicone PEG-15 Crosspolymer is a crosslinked copolymer formed from PEG-15 and Lauryl Dimethicone
