Is Cetyl Betaine natural?

Mostly. The oleochemical cetyl chain is natural; the dimethylamino and acetate head group come from petrochemical methylating and chloroacetate reagents.

How we scored it

Cetyl chain (oleochemical, natural) C16H33 225.4 Da vs N(CH3)2CH2COO head group (petrochemical, methylation + chloroacetate) 102.1 Da → 225.4/327.5 = 0.69
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

Cetyl Betaine is made from cetyl, a palm- or coconut-derived fatty amine, methylated with petrochemical reagents and quaternized with sodium chloroacetate. Most of the molecule's mass comes from the natural fatty chain.

In plain English

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