Is Cocamidopropyl Hydroxysultaine natural?

Mostly. Coconut acid and the sulfonate group are natural; the DMAPA-derived linker and hydroxypropylene tail are petrochemical.

How we scored it

Lauroyl 183.3 Da + SO3 80.1 Da = 263.4 Da (natural) vs DMAPA-propyl-N(CH3)2 plus hydroxypropylene tail carbons ~159.3 Da (petrochemical). 263.4/422.6=0.62.
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.

How it’s made

Chlorohydroxypropanesulfonate closes to an epoxide; the amidoamine opens it (SN2). Each curved arrow moves one electron pair, and the film ends on the score above.

Where it comes from

Amphoteric surfactant made from coconut fatty acid and dimethylaminopropylamine (DMAPA), further reacted with a sultone-type reagent to add the sulfonate group. The sulfonate itself counts as mineral-natural even though its carbon backbone is petrochemical.

In plain English

A mild, amphoteric surfactant made from coconut fatty acid joined to a synthetic amine linker and a sulfonate group. It boosts foam and gentleness in cleansers and shampoos.
