How we scored it
Stearic acid (natural, oleochemical) + glutamic acid (natural, fermentation) joined by amide bond, condensation water not counted; Na counterion natural. Whole molecule = 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 vegetable-derived stearic acid with fermentation-derived glutamic acid, then neutralising with sodium. All building blocks are natural-origin.
In plain English
A mild, plant-derived cleansing and conditioning ingredient used in cleansers and skin or hair products. It is made by combining stearic acid from vegetable fat with the amino acid glutamic acid, then neutralising with sodium.
Structure
sodium (4S)-5-hydroxy-4-(octadecanoylamino)-5-oxopentanoate
