Is Palmitamidopropyl Betaine natural?

Mostly. Palmitic acid chain from palm oil is natural; the propyl-betaine head group derives from petrochemical DMAPA and sodium chloroacetate.

How we scored it

Palmitoyl C16H31O (239.4 Da, natural) / total C23H46N2O3 (398.6 Da); remaining amidopropyl-dimethyl-acetate head (159.2 Da) from DMAPA + chloroacetate is petrochemical. 239.4/398.6=0.60.
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

Made by amidating palm-derived palmitic acid with dimethylaminopropylamine, then reacting with sodium chloroacetate to form the betaine. The fatty chain is oleochemical; the amine and acetate head are synthetic.

In plain English

A foaming and conditioning surfactant made by combining palmitic acid, a fatty acid from palm oil, with a synthetic amine building block. Used in shampoos and cleansers to boost foam and reduce static.
