Is Bis-PEG-15 Methyl Ether Dimethicone natural?

No. Siloxane is 0.0 by this site's convention and the PEG-15 blocks are polymerised petrochemical ethylene oxide, so no fragment is credited.

How we scored it

Silicone with PEG-15 (ethylene oxide) end blocks: silicone scored 0.0 by this site's convention and ethylene oxide is petrochemical anyway; 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 a methyl-capped allyl polyether (allyl alcohol ethoxylated to about 15 ethylene oxide units) onto a hydride dimethicone. No natural-origin route is commercially significant.

In plain English

A water-dispersible silicone surfactant that helps emulsify and condition hair and skin. It is a dimethicone chain with two polyethylene glycol (PEG-15) ends capped with methyl ethers.

CosIng definition: Bis-Peg-15 Methyl Ether Dimethicone is the methyl ether of a derivative of Dimethicone end-blocked with an average of 15 moles of ethylene oxide
