Is Oleamidopropyl Hydroxysultaine natural?

Mostly. Oleic acid, typically from vegetable oil, supplies the fatty amide; the sultaine head is built from petrochemical DMAPA and a propanesultone reagent.

How we scored it

Oleoyl (natural, oleic acid) C18H33O 265 Da; amidopropyl-dimethyl-hydroxypropanesulfonate backbone (DMAPA+propanesultone, petrochemical) 239 Da -> 265/504.8=0.53.
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 from vegetable oils (e.g. canola, olive) is amidated with petrochemical DMAPA then reacted with a propanesultone or epichlorohydrin/sulfite reagent to install the sulfonate. The zwitterionic sulfonate is treated here as part of the synthetic backbone, not a separable mineral fragment.

In plain English

A mild, skin-conditioning surfactant used in gentle cleansers. It is made from oleic acid, a natural fatty acid, combined with petrochemical amine and sulfonate groups.
