How we scored it

Behenoyl C22H43O (323.6 Da, from behenic acid) natural; DMAPA + chloroacetate betaine portion (159.2 Da) petrochemical -> 323.6/482.8=0.67.
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

The fatty portion is made by amidating behenic acid, a C22 oleochemical fatty acid from vegetable oil, with synthetic dimethylaminopropylamine, then quaternising with sodium chloroacetate. Only the fatty chain is natural-origin.

In plain English

A mild, foam-boosting cleansing surfactant derived partly from a long-chain vegetable fatty acid. The rest of the molecule, including the part that carries its electrical charge, is made from synthetic building blocks.
