How we scored it

Tripeptide of glutamate, cysteine and glycine; amino acids are fermentation/hydrolysate products. 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

Produced industrially by yeast fermentation, or extracted from yeast. As a peptide of natural amino acids, no petrochemical mass is introduced during assembly.

In plain English

A small protein-like molecule (tripeptide) used as an antioxidant and brightening ingredient. Produced mainly by fermenting yeast. Made entirely of natural amino acid building blocks.
