Is Disodium Isostearamido MIPA-Sulfosuccinate natural?

Mostly. Sulfosuccinate half-ester: the fatty hydrophobe is oleochemical and both sodium counter-ions and the sulfonate group are mineral-derived, so all count as natural; the four-carbon succinate backbone comes from petrochemical maleic anhydride, and the ethoxylate/alkanolamide linker is petrochemical too. Same convention as Disodium Lauryl Sulfosuccinate.

How we scored it

Isostearoyl C18H35O 267.5 Da (natural) + SO3Na 103.0 Da + Na 23.0 Da (mineral, natural) = 393.5 Da; MIPA linker C3H7NO 73.1 Da + succinate backbone C4H3O3 99.1 Da (maleic anhydride) = 172.2 Da petrochemical; total 565.7 Da → 393.5/565.7 = 0.70.
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

Fatty alcohol or fatty-acid alkanolamide from coconut, palm, tallow or vegetable oil reacted with maleic anhydride, then sulfonated with sodium bisulfite.

In plain English

A conditioning surfactant made from a branched fatty acid related to oleic acid, joined to a synthetic amine and acid backbone. Used in mild shampoos and body washes to boost foam and softness.

CosIng definition: Butanedioic acid, sulfo-, 1-ester with N-(2-hydroxypropyl)isooctadecanamide, disodium salt
