How we scored it
C13H21NNa2O5 317.3: octanoyl 127.2 (coconut) + glutamyl core 144.1 (fermentation) + Na2 46.0 (mineral); all natural: 317.3/317.3 = 1.00.
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
Oleochemical caprylic acid (as its acid chloride) is reacted with fermentation-derived glutamic acid and neutralised with sodium hydroxide. No significant petrochemical route is known.
In plain English
A plant-derived cleansing agent that helps foam and also acts as a deodorant ingredient. It joins caprylic acid from coconut or palm kernel oil to glutamic acid from fermentation, as its sodium salt.
