How we scored it

Na+ (mineral ion, natural) + aspartate C4H6NO4 (fermentation amino acid) = 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 reacting sodium hydroxide or carbonate with fermentation-derived L-aspartic acid. No significant alternative route exists.

In plain English

A sodium salt of the amino acid aspartic acid, used as a humectant and conditioning agent. The sodium is mineral and the aspartic acid comes from fermentation.
