How we scored it
Cell lysate extract from bacterial fermentation: cell components and metabolites are all biologically derived, so 1.0. Medium salts, pH adjusters and extraction solvents leave no counted mass.
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
Bacillus is grown by submerged fermentation on sugar and nitrogen feedstocks, then the cells are lysed and the extract filtered. No synthetic route exists; the exact strain and medium vary by supplier.
In plain English
An extract made from Bacillus bacteria grown by fermentation, then broken open (lysed) and extracted. It is used as a skin-conditioning ingredient. It comes from a microbial culture grown on a nutrient medium, not from a synthetic process.
CosIng definition: Bacillus Ferment Lysate Extract is the extract of the lysed cells obtained through fermentation by Bacillus.
