How we scored it

Caprylamide acyl (C8 coconut) C8H15O 127.2 Da + 2 Na 46.0 Da = 173.2 Da natural; aminoethylethanolamine backbone plus two acrylate arms 245.2 Da petrochemical. 173.2/418.4 = 0.41.
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 reacting caprylic acid from coconut oil with aminoethylethanolamine (a petrochemical amine) then modifying with two sodium acrylate arms (also petrochemical). Sodium counter-ions are mineral-derived and natural.

In plain English

A mild, low-irritation cleansing surfactant made from caprylic acid (a coconut-oil fatty acid) combined with lab-made nitrogen and acrylate building blocks. Used in baby shampoos and gentle cleansers to produce foam without stripping skin or hair.
