How we scored it

Isoleucine C6H13NO2, a proteinogenic amino acid; amino acids are fermentation/hydrolysate products, fully natural-origin. 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 bacterial fermentation of plant-derived sugars, the same route used for food-grade amino acids; also recoverable from hydrolysed protein. No petrochemical route is used.

In plain English

An amino acid that conditions hair and skin. Like other amino acids used in cosmetics, it's typically made by fermenting plant sugars with bacteria.
