How we scored it

Potassium salt of citric acid; citric acid (fermentation) and potassium (mineral) are both 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

Made by neutralising fermentation-derived citric acid with a potassium mineral base (e.g. potassium hydroxide or carbonate). No petrochemical route is used.

In plain English

A mineral salt used to stabilise a formula's acidity and bind trace metals. Made by neutralising citric acid, a fermentation product, with a potassium mineral base.
