Is Lauramidopropyl Hydroxysultaine natural?

Mostly not. Lauric acid supplies the natural acyl group; the DMAPA amine and hydroxysultaine linkage are petrochemical.

How we scored it

Lauroyl (dodecanoyl) C12H23O natural fatty fragment = 183.3 Da; DMAPA-derived propyl-dimethylammonium + hydroxypropanesulfonate (epichlorohydrin/bisulfite) petrochemical = 239.3 Da → 183.3/422.6 = 0.43.
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 lauric acid (coconut-derived) with dimethylaminopropylamine (DMAPA), then reacting with a propanesultone-type agent to form the hydroxysultaine. The fatty acid is natural; the amine and sultaine chemistry are petrochemical.

In plain English

A mild amphoteric surfactant used in shampoos and cleansers, made by combining lauric acid from coconut or palm oil with a petrochemical amine and sulfonate group. Part plant-derived, part synthetic.
