Is Erucamidopropyl Hydroxysultaine natural?

Mostly. The erucic fatty chain and the sulfonate group are natural; the amidopropyl-dimethylammonium head and the hydroxypropyl linker are petrochemical.

How we scored it

Erucoyl C22H41O 321.6 Da (rapeseed erucic acid, natural) + sulfonate SO3 80.1 Da (mineral) = 401.6 Da natural; DMAPA and hydroxypropyl linker petrochemical; total C30H60N2O5S 560.9 Da → 0.72. Same method as Cocamidopropyl Hydroxysultaine.
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

Erucic acid amidated with DMAPA and reacted with sodium 3-chloro-2-hydroxypropanesulfonate.

In plain English

A mild cleansing and conditioning ingredient made from erucic acid, a natural fatty acid from rapeseed or mustard oil, joined to a lab-made surfactant backbone.
