How we scored it

Coco acyl (lauroyl proxy) C12H23O 183.3 Da + SO3 80.1 Da + Na 23.0 Da = 286.4 Da natural; aminoethylethanolamine and hydroxypropyl linker petrochemical; total C19H37N2NaO6S 444.6 Da → 0.64.
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

Coconut fatty acid condensed with aminoethylethanolamine and reacted with sodium 3-chloro-2-hydroxypropanesulfonate.

In plain English

A mild, foam-boosting cleansing ingredient made from coconut-derived fatty acid combined with synthetic petrochemical building blocks. Common in gentle shampoos and baby washes.
