How we scored it
Fermentation biomass/metabolite complex plus manganese ion; fermentation products are 1.0 and manganese is a natural mineral ion.
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 fermenting Saccharomyces yeast in a manganese-enriched medium, producing a mineral-bound ferment lysate. No synthetic alternative exists.
In plain English
A skin-conditioning ingredient made by fermenting yeast with manganese, which becomes bound into the yeast's cell material. It is a natural fermentation product.
CosIng definition: Saccharomyces/Manganese Ferment is the product obtained by the fermentation of Saccharomyces in the presence of manganese ions
