Is PEG-14 Oleate natural?

Mostly not. Polyethylene glycol ester of oleic acid. The fatty-acid chain is natural; the 14-unit ethylene-oxide chain is petrochemical.

How we scored it

PEG-14 Oleate: oleoyl fragment C18H33O 265.5 Da (natural) of oleic acid 282.5 Da + 14 EO 616.7 Da = 899.2 Da → 0.30. The ester oxygen and chain-end hydrogen are counted with the PEG chain, as for PEG-8 Laurate and PEG-8 Oleate.
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

Oleic acid esterified or ethoxylated with about 14 mol of ethylene oxide.

In plain English

An emulsifying ingredient made from plant oleic acid reacted with about 14 units of ethylene oxide. The data record's formula field looks mismatched and should be checked.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxo-9-octadecenyl)-.omega.-hydroxy-, (Z)- (14 mol EO average molar ratio)
