Is Disodium Stearyl Sulfosuccinamate natural?

Mostly. The stearyl chain, the sulfonate and both sodium ions are natural; the amine nitrogen and the succinamate backbone are petrochemical. Same conventions as Stearamine and the sulfosuccinates.

How we scored it

C22H41NNa2O6S 493.6 Da: stearyl C18H37 253.5 Da (oleochemical) + SO3 80.1 Da + 2 Na 46.0 Da (mineral) = 379.5 Da natural; the amide NH (synthetic ammonia via stearylamine) and the C4 succinamate backbone (maleic anhydride) are petrochemical → 0.77.
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

Stearylamine reacted with maleic anhydride, then sulfonated with sodium bisulfite.

In plain English

A mild cleansing and foam-boosting surfactant made from a plant/animal-derived fatty (stearyl) amine linked to a sulfosuccinate group, sold as a sodium salt.
