How we scored it
Lysate of Lactobacillus cells from fermentation: proteins, peptides, lipids, nucleic acids and cell-wall polysaccharides, 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, with the cells then broken open (lysed) and the liquid filtered. The growth medium varies by supplier and is not given by the INCI.
In plain English
Lactobacillus cells, the lactic acid bacteria also found in yoghurt, grown by fermentation and then broken open. The resulting liquid is listed in skincare products for an antimicrobial function and is made from the bacteria and their growth medium.
CosIng definition: Lactobacillus Lysate is the lysate of Lactobacillus obtained through fermentation.
