Is Ricinoleamidopropyl Betaine natural?

Mostly. Ricinoleic acid from castor oil is natural; the dimethylaminopropylamine and chloroacetate that form the betaine head group are petrochemical.

How we scored it

Ricinoleoyl (castor oil) 281.5 Da natural; DMAPA (petrochemical amine) 101.2 Da + chloroacetate-derived carboxymethyl (petrochemical) 58 Da = 159.2 Da; 281.5/440.7 = 0.64
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 castor oil fatty acid with petrochemical dimethylaminopropylamine, then quaternising with chloroacetic acid to form the betaine. No natural route exists for the amine or the carboxymethyl group.

In plain English

A mild, conditioning surfactant used in gentle shampoos and body washes. It's made from castor oil fatty acid combined with petroleum-derived building blocks to form a betaine cleanser.

CosIng definition: 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-castor-oil acyl derivs., hydroxides, inner salts
