How we scored it
Single amino acid, produced by fermentation of plant sugars = 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
Commercially produced by bacterial fermentation of plant-derived sugars, similar to glutamic acid/MSG production. No significant petrochemical route is used.
In plain English
An amino acid used to condition hair and skin and reduce static cling. Usually produced by fermenting plant sugars, as with many cosmetic-grade amino acids.
Structure
(2S)-2,5-diamino-5-oxopentanoic acid
