How we scored it
Fermentation biomass/metabolite complex plus mineral silicon; fermentation products are 1.0 and silicon (from silica) is natural-origin mineral.
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 silicon-enriched medium, yielding a mineral-bound ferment lysate. No petrochemical route exists.
In plain English
A skin-conditioning ingredient made by fermenting yeast with silicon, which becomes incorporated into the yeast's cell material. It is a natural fermentation product.
CosIng definition: Saccharomyces/Silicon Ferment is the product obtained by the fermentation of Saccharomyces in the presence of silicon
