How we scored it
Filtrate extract of a bacterial fermentation: all atoms from microbial metabolism of a sugar or plant-juice medium; fermentation-product rule gives 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 fermentation of Gluconacetobacter xylinus on a sugar-based medium, followed by filtration and extraction. Any preservative or carrier added in the finished product is not part of the ingredient.
In plain English
A moisturising, skin-softening ingredient taken from the liquid left after the bacterium Gluconacetobacter xylinus ferments a sugar-based medium. It contains the dissolved by-products of that fermentation.
CosIng definition: Gluconacetobacter Xylinus Ferment Filtrate Extract is the extract of a filtrate of the product obtained through the fermentation by Gluconacetobacter xylinus.
