How we scored it
Yeast fermentation filtrate extract: microbial metabolites (n=1) plus chromium ions (mineral, n=1); media and solvents ignored. 100% / 100% = 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
Dominant route is culturing Saccharomyces yeast in a medium containing chromium ions, then extracting and filtering the broth. No commercially significant non-biological route exists.
In plain English
A liquid made by growing yeast (Saccharomyces) in the presence of chromium ions, then extracting and filtering the culture. It is used in skin-care products to condition the skin. It comes from yeast fermentation plus a mineral source of chromium.
CosIng definition: Saccharomyces/Chromium Ferment Extract Filtrate is a filtrate of an extract of the product obtained through fermentation by the microorganism, Saccharomyces in the presence of chromium ions.
