Is Oleamidopropylamine Oxide natural?

Mostly. Fatty chain is vegetable-oil oleic acid (natural); the dimethylaminopropyl head group is a petrochemical synthetic amine (DMAPA).

How we scored it

Oleic acid (vegetable oil) acyl C18H33O 265.5 Da natural + amidopropyl-dimethylamine-oxide C5H12N2O 117.2 Da (DMAPA, petrochemical, plus oxidation O) = 382.6 Da. 265.5/382.6 = 0.69.
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 from vegetable oil with DMAPA (dimethylaminopropylamine), a petrochemical amine, then oxidising the nitrogen. No significant alternative route exists.

In plain English

A mild foaming and conditioning surfactant made from oleic acid, a fatty acid from vegetable oils, combined with a lab-made amine, then oxidised. Used in shampoos and cleansers.
