How we scored it
Palmitic acid (256.4, oleochemical) + glutamic acid (147.1, fermentation) − H2O (18, condensation) = 385.5, matches MW; both 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 amide-coupling palm/coconut-derived palmitic acid with L-glutamic acid from fermentation. Assumes oleochemical fatty-acid supply typical for cosmetic grade.
In plain English
A conditioning ingredient made from palm-oil fatty acid joined to the amino acid glutamic acid. Used in skincare to help condition skin. Built from plant oil and a fermentation-derived amino acid.
Structure
(2S)-2-(hexadecanoylamino)pentanedioic acid
