Is PEG-150 Laurate natural?

Mostly not. Small lauric-acid ester end-group on a long petrochemical polyethylene-glycol (150 EO) chain that dominates molecular mass.

How we scored it

Given formula/MW match PEG-1 laurate, not PEG-150, per cosing description; recomputed: lauroyl 183 Da (natural) + 150 EO chain ~6625 Da (petrochemical), ester ~6808 Da, 183/6808=0.03.
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 esterifying oleochemical lauric acid with polyethylene glycol built from 150 units of petrochemical ethylene oxide. The long PEG chain supplies almost all the molecule's mass.

In plain English

A cleansing ingredient combining coconut or palm-derived lauric acid with a long synthetic polyethylene glycol chain. Mostly petroleum-based because the PEG chain makes up nearly all its weight.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxododecyl)-.omega.-hydroxy- (150 mol EO average molar ratio)
