How we scored it
Extract of lysed Lactobacillus cells: proteins, peptides, lipids, nucleic acids, cell-wall polysaccharides and metabolites, all microbial n=1. Medium and lysis reagents leave no mass. 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 Lactobacillus grown by fermentation on a sugar-and-nitrogen medium, then lysed and extracted. The INCI does not name the medium, so retained non-natural medium components cannot be fully excluded.
In plain English
An extract of Lactobacillus bacterial cells, the lactic acid bacteria also used in yoghurt, that have been grown in culture and then broken open (lysed). It is listed in skincare products for a skin-protecting function and is made from the bacterial cells.
CosIng definition: Lactobacillus Ferment Lysate Extract is the extract of the lysed cells of Lactobacillus grown in culture.
