How we scored it
Filtrate of lysed Leuconostoc cells grown on plant-derived medium; filtration adds no mass. All fragments microbial or plant-derived: 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
Leuconostoc bacteria are cultured on a plant-based nutrient medium, the cells are lysed and the liquid is filtered. There is no alternative route.
In plain English
A clear liquid from Leuconostoc bacteria that are grown, broken open and filtered. It is used to soften and condition skin and comes from microbial fermentation of plant-based nutrients.
CosIng definition: Leuconostoc Ferment Lysate Filtrate is a filtrate of the product obtained after the lysis of the cultured cells of the microorganism Leuconostoc.
