How we scored it
Fermentation biomass/metabolite complex plus calcium ion; fermentation products are 1.0 and calcium is a natural mineral counter-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
Produced by fermenting Saccharomyces yeast in a calcium-enriched growth medium, yielding a mineral-bound ferment lysate. No petrochemical route exists.
In plain English
A skin-conditioning ingredient made by fermenting yeast in the presence of calcium, which the yeast incorporates into its cell material. It is a natural fermentation product.
CosIng definition: Saccharomyces/Calcium Ferment is the fermentation product of Saccharomyces in the presence of calcium ions
