How we scored it

Lauric acid (coconut/palm, natural) amide of glutamic acid (fermentation amino acid, natural) with sodium (mineral, natural) = 1.0
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

Schotten–Baumann acylation of glutamate by lauroyl chloride. Each curved arrow moves one electron pair, and the film ends on the score above.

Where it comes from

Made by combining lauric acid from coconut or palm kernel oil with glutamic acid, an amino acid produced by fermentation, then neutralising with sodium.

In plain English

A mild cleansing and conditioning ingredient made from coconut or palm fatty acid combined with a fermented amino acid. It is used in gentle shampoos to reduce static and add softness.
