Is Oleamine Oxide natural?

Mostly. The oleyl chain comes from oleic acid in vegetable oils; the dimethylamine-oxide head group comes from synthetic dimethylamine and hydrogen peroxide.

How we scored it

Oleyl chain C18H35 (251.5 Da, vegetable-oil derived) / total C20H41NO (311.5 Da); dimethylamine-oxide head C2H6NO (60.1 Da) from synthetic dimethylamine is petrochemical. 251.5/311.5=0.81.
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 reacting oleic-acid-derived oleylamine with dimethylamine, then oxidizing with hydrogen peroxide. The fatty chain is vegetable-oil derived; the head group's methyl carbons are petrochemical.

In plain English

A surfactant made from oleic acid, a fatty acid from vegetable oils, combined with a small synthetic dimethylamine-oxide head group. Used in cleansers to boost foam and reduce static.
