How we scored it

Mg2+ 24.3 Da (mineral ion, natural) + 2x lactate C3H5O3 178.1 Da (fermentation) = 202.4/202.4 = 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 lactic acid with a magnesium base. No significant alternative route exists.

In plain English

A magnesium salt of lactic acid, used to buffer pH and condition skin. The magnesium is mineral and the lactic acid comes from fermentation of plant sugars.
