Is Sodium Lauroamphopropionate natural?

Mostly not. Lauric acid chain from coconut oil is natural; the hydroxyethyl-aminopropionate backbone derives from synthetic aminoethylethanolamine and acrylate-type feedstocks.

How we scored it

Lauroyl C12H23O (183.3 Da, coconut-derived) / total C19H37N2NaO4 (380.5 Da); hydroxyethyl-aminopropionate/sodium backbone (197.2 Da) from synthetic amine + acrylate-type reagents is petrochemical. 183.3/380.5=0.48.
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 condensing coconut-derived lauric acid with an aminoethylethanolamine-type amine, then reacting with an acrylate or chloroacetate building block and neutralizing with sodium hydroxide. Only the fatty chain is oleochemical.

In plain English

An amphoteric surfactant made from coconut-derived lauric acid joined to a synthetic ethanolamine/acrylate-type building block, then neutralized with sodium. Used in shampoos and cleansers for foam and conditioning.
