Is PEG-20 Laurate natural?

Mostly not. The fatty lauroyl chain is coconut/palm-kernel derived; the 20-unit ethylene oxide chain is petrochemical and dominates the mass.

How we scored it

Lauroyl (C12H23O, 183 Da, coconut-derived) esterified to PEG-20 (20 EO, ~899 Da, petrochemical) minus H2O: 183/1081 ≈ 0.17.
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 ethoxylating lauric acid (from coconut or palm kernel oil) with 20 moles of petrochemical ethylene oxide. No major alternative route.

In plain English

A mild cleansing and emulsifying ingredient made by reacting coconut-derived lauric acid with a long chain of ethylene oxide. Most of its weight comes from the petroleum-based portion.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxododecyl)-.omega.-hydroxy- (20 mol EO average molar ratio)
