Is Disodium Ricinoleamido MEA-Sulfosuccinate natural?

Mostly. Ricinoleic acid from castor oil is amidated to ethanolamine, then half-esterified with petrochemical maleic anhydride and sulfonated; sulfonate and sodium ions count as natural minerals.

How we scored it

Ricinoleoyl (castor oil, natural) C18H33O2 281 Da + SO3+2Na (mineral, natural) 126 Da = 407 Da; MEA-ethylene + succinate backbone (petrochemical) 158 Da -> 407/565.6=0.72.
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

Castor oil-derived ricinoleic acid is amidated with ethanolamine (from petrochemical ethylene oxide/ammonia), then reacted with maleic anhydride and sodium bisulfite to form the sulfosuccinate. The fatty chain is natural; the ethanolamine and succinate backbone are petrochemical.

In plain English

A mild, foam-boosting surfactant used in gentle cleansers. It combines ricinoleic acid from castor oil with petrochemical ethanolamine and a sulfosuccinate group.
