Is PEG/PPG-19/19 Dimethicone natural?

No. Silicone backbone is zero by convention; ethoxylate and propoxylate chains are petrochemical; nothing natural remains in the molecule.

How we scored it

Dimethicone backbone (silicone, 0) + 19 mol ethylene oxide (0) + 19 mol propylene oxide (0). No natural fragment: 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

Made by reacting a hydroxypropyl dimethicone with petrochemical ethylene oxide and propylene oxide. No natural-origin route is used commercially for this silicone copolymer.

In plain English

A silicone-based emulsifier used in skin and hair products to blend water and oil phases. It is produced entirely from synthetic silicone and petrochemical feedstocks.

CosIng definition: Siloxanes and silicones, dimethyl, 3-hydroxypropyl methyl, ethoxylated, propoxylated (19 mol EO, 19 mol PO average molar ratio)
