How we scored it
Myristic acid (natural, C14 fatty acid) amide-bonded to glutamic acid (fermentation amino acid); sodium mineral counter-ion. All fragments 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.
Where it comes from
Made by condensing myristic acid (from coconut or palm kernel oil) with L-glutamic acid (produced by fermentation), then neutralising with sodium. Used as a mild amino-acid-based cleansing surfactant.
In plain English
A gentle cleansing ingredient made from coconut or palm fatty acid combined with the amino acid glutamic acid. Both building blocks are natural, made from plant oil and fermentation.
Structure
