Is Isostearamidopropyl Betaine natural?

Mostly. Isostearic acid derives from natural vegetable-oil fatty acids; the DMAPA amine and acetate cap are petrochemical.

How we scored it

Isostearoyl fragment (natural, from oleic-acid isomerisation) 267 Da / total 427 Da = 0.63; DMAPA backbone + acetate cap petrochemical.
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

Made by amidating isostearic acid (from isomerised natural fatty acids) with DMAPA, then quaternising with chloroacetic acid. No significant alternative route.

In plain English

A mild surfactant made from isostearic acid, a branched fatty acid from vegetable oil, joined to a lab-made amine building block. Used in cleansers to boost foam and condition skin and hair.
