Is PEG-7 Oleate natural?

Mostly not. Oleic acid from vegetable oil provides the natural acyl fragment; the 7-unit ethylene oxide chain is petrochemical and dominates the molecule's mass.

How we scored it

Supplied formula (326.5) is the 1-EO structure and contradicts the '7 mol EO' description; recomputed: oleoyl 265.46 (natural) / [265.46 + 7x44.05 + 17.01 = 590.84] = 0.45.
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 oleic acid from vegetable oils such as palm or sunflower with about 7 moles of petrochemical ethylene oxide. No natural route exists for the polyoxyethylene chain.

In plain English

An emulsifier and cleansing ingredient made by reacting a plant-oil fatty acid with ethylene oxide, a petroleum-derived building block. It helps oil and water mix in creams and cleansers.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxo-9-octadecenyl)-.omega.-hydroxy-, (Z)- (7 mol EO average molar ratio)
