Is Dimethicone/Bis-Isobutyl PPG-20 Crosspolymer natural?

No. Silicone crosspolymer backbone (dimethicone crosslinked with PPG-20) is scored 0 by this site's convention; both silicone and PPG portions are petrochemical anyway.

How we scored it

Crosslinked dimethicone/PPG-20 network; site-convention 0.00 for silicones applies to the whole crosspolymer regardless of the propoxylated crosslinker → 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

Produced by crosslinking hydrogen dimethicone with a bis-methallyl-capped PPG-20 chain, both petrochemical polymers. No natural-origin route exists for either the silicone or the propoxylated crosslinker.

In plain English

A silicone-based gel ingredient that gives creams and lotions a smooth, cushiony feel. It's a fully synthetic, crosslinked silicone polymer with no natural content.

CosIng definition: Dimethicone/Bis-Isobutyl PPG-20 Crosspolymer is a crosslinked polymer of Hydrogen Dimethicone crosslinked with bis-methallyl PPG-20
