How we scored it

Oleyl chain (oleochemical, natural) C18H35 251.5 Da vs N(CH3)2CH2COO head group (petrochemical) 102.1 Da → 251.5/353.6 = 0.71
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

Oleyl Betaine is made from oleyl, a vegetable-oil-derived fatty amine, methylated and quaternized with sodium chloroacetate, both petrochemical steps. Most of the molecule's mass comes from the natural oleyl chain.

In plain English

A mild cleansing and conditioning ingredient made mostly from a vegetable-oil-derived fatty chain, combined with a small synthetic head group.
