Is PEG-2 Oleamine natural?

Mostly. Ethoxylated fatty amine. The vegetable-oil oleyl alkyl chain is natural; the amine nitrogen comes from synthetic ammonia and the 2 ethylene-oxide units are petrochemical, as on the site's plain fatty-amine entries.

How we scored it

Oleyl chain C18H35 251.5 Da (natural) ; nitrogen 14.0 Da (synthetic ammonia, petrochemical as for the parent fatty amine) + 2×EO 88.1 Da + 2 terminal H (petrochemical ethylene oxide); total 355.6 Da → 251.5/355.6 = 0.71.
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

Vegetable-oil oleyl fatty amine (fatty nitrile hydrogenated with ammonia-derived nitrogen) reacted with about 2 mol of ethylene oxide.

In plain English

An emulsifier made from a fatty substance, typically derived from vegetable oil, combined with a small amount of a petroleum-derived chemical. Most of its weight comes from the plant-derived part.
