Is Disodium Caproamphodiacetate natural?

Mostly not. Capric acid from coconut or palm kernel oil and sodium are natural; the aminoethylethanolamine backbone and two chloroacetate-derived carboxymethyl arms are petrochemical.

How we scored it

Decanoyl C10H19O 155.3 + 2 Na 46.0 = 201.2 natural; amine backbone and two carboxymethyl arms 217.2 petrochemical; 201.2 / 418.4 = 0.48.
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

Capric acid (oleochemical) is condensed with aminoethylethanolamine (from ethylene oxide and ethylenediamine) and carboxymethylated twice with sodium chloroacetate. No bio-based amine backbone is commercial.

In plain English

An amphoteric surfactant used in cleansers and shampoos for foaming and conditioning. Its C10 fatty part comes from coconut or palm kernel oil; the amine backbone is petrochemical.
