How we scored it

2×oleoyl(531) natural; hexaethylene glycol backbone(282-2H=280) petrochemical; supplied formula matched n=1 not 6, recalculated; 531/811=0.65.
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

Diester of oleic acid (from vegetable oil) with hexaethylene glycol made from petrochemical ethylene oxide. No alternative route for the glycol portion.

In plain English

An emulsifier made from oleic acid, a natural fatty acid from vegetable oils, joined to a short synthetic petrochemical glycol chain.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxo-9-octadecenyl)-.omega.-[(1-oxo-9-octadecenyl)oxy]-, (Z,Z)- (6 mol EO average molar ratio)
