Is PEG-12 Dimethicone/PPG-20 Crosspolymer natural?

No. The silicone backbone is 0.0 by this site's convention and the polyether chains come from petrochemical ethylene oxide and propylene oxide, so no fragment is natural origin.

How we scored it

Dimethicone backbone 0.0 by this site's convention; PEG-12 chains and bis-allyl PPG-20 crosslinker are ethylene oxide and propylene oxide units, n = 0; no natural fragment, so 0 / total = 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

Hydrogen dimethicone is grafted with allyl-PEG-12 and crosslinked with bis-allyl PPG-20 by platinum-catalysed hydrosilylation. No natural-origin route exists.

In plain English

A crosslinked silicone elastomer carrying polyether (PEG and PPG) chains that let it mix with water-based ingredients. It gives a smooth, silky feel and can help stabilise emulsions. It is made entirely by synthetic chemistry.

CosIng definition: PEG-12 Dimethicone/PPG-20 Crosspolymer is a crosslinked polymer of Hydrogen Dimethicone crosslinked with Bis-allyl PPG-20.
