How we scored it
Filtrate of a bacterial fermentation: microbial metabolites and residual nutrient-medium components, all natural-origin fermentation material; no synthetic fragment: 1.00.
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
Alteromonas macleodii is cultured in a fermenter on a nutrient growth medium and the broth is filtered to remove the cells. No alternative route is commercially significant.
In plain English
A liquid left after the marine bacterium Alteromonas macleodii has been grown in a nutrient medium and the cells filtered out. It holds what the bacteria released into the medium and is listed as a humectant, meaning a moisture-attracting ingredient.
CosIng definition: Alteromonas Ferment Filtrate is a filtrate of the product obtained by the fermentation of a growth media by the microorganism, Alteromonas macleodii
