Mostly natural · ISO 16128

Is Myristamidopropyl Betaine natural?

Mostly. The fatty myristoyl chain comes from natural myristic acid, but the DMAPA and chloroacetate-derived betaine head group are petrochemical, as in cocamidopropyl betaine.

How we scored it

Myristoyl fragment C14H27O 211Da natural (myristic acid); DMAPA+chloroacetate betaine fragment 160Da petrochemical -> 211/371 = 0.57.
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

Myristic acid (coconut/palm-kernel derived) is amidated with petrochemical DMAPA, then reacted with sodium chloroacetate to form the betaine. Used as a mild co-surfactant.

In plain English

A mild, foam-boosting surfactant used in cleansers and shampoos. Its fatty part comes from coconut or palm-kernel oil, while the charged head group is built from petrochemical building blocks.
