How we scored it
Fermentation product (microbial biomass and metabolites from sugar and protein media) is natural origin, n = 1. CosIng names Bacillus; the INCI name implies Bifidobacterium; value is unchanged. 1.0 / 1.0 = 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
Dominant route is batch fermentation of a bacterial culture on a sugar, milk or protein-based medium, followed by extraction and filtration of the broth. Organism and medium vary by supplier, but every common route gives a microbial fermentation product.
In plain English
A liquid filtered from an extract of a fermented bacterial culture, listed for oral-care use. The bacteria are grown on a nutrient broth, the culture is extracted, and solids are filtered out. It is a microbial fermentation product rather than a synthetic chemical.
CosIng definition: Bifida Ferment Extract Filtrate is a filtrate of an extract of the product obtained through fermentation by the microorganism Bacillus.
