Mostly natural · ISO 16128

Is Oleamidopropyl Betaine natural?

Mostly. Natural oleic acid is condensed with petrochemical dimethylaminopropylamine, then quaternised with petrochemical sodium chloroacetate to form the betaine group.

How we scored it

Oleoyl C18H33O 265 Da (natural) + DMAPA/chloroacetate-derived betaine fragment C7H15N2O2 159 Da (petrochemical); 265/424 = 0.62.
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 reacting vegetable-derived oleic acid with synthetic dimethylaminopropylamine (DMAPA), then reacting the product with synthetic sodium chloroacetate. The fatty portion is natural; the amine and betaine-forming reagents are petrochemical.

In plain English

A mild, foam-boosting and conditioning surfactant used in cleansers and shampoos. It is made by reacting natural oleic acid from vegetable oil with synthetic amine and acid building blocks.
