Is Isostearamidopropylamine Oxide natural?

Mostly. The fatty acyl chain is natural; the dimethylaminopropylamine head and its N-oxide are petrochemical.

INCI nameIsostearamidopropylamine Oxide
FormulaC21H44N2O2 · 356.6 Da
FunctionCleansing · Foam Boosting Surfactant
FeedstockIsostearoyl acid amidated with DMAPA and oxidised with…

How we scored it

Isostearoyl C18H35O 267.5 Da (oleochemical, natural) + amidopropyl-dimethylamine-oxide head C5H13N2O 117.2 Da (DMAPA, petrochemical); total C23H48N2O2 384.6 Da → 0.70. Same method as Oleamidopropylamine Oxide.
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

Isostearoyl acid amidated with DMAPA and oxidised with hydrogen peroxide.

In plain English

A mild foam-boosting cleansing ingredient made from isostearic acid (a branched vegetable-derived fatty acid) combined with a synthetic petrochemical amine building block. Used in shampoos and cleansers.
