How we scored it
Filtered extract of a lysed bacterial fermentation; mass is microbial biomass and culture-derived material; fermentation products = 1.0, so no fragment arithmetic is needed.
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: submerged fermentation of Pseudoalteromonas on a nutrient medium, then cell lysis, extraction and filtration. Supplier note: commercial grades are often sold in glycol or glycerin carriers, which would change the as-supplied value.
In plain English
A skin-conditioning ingredient made by growing the marine bacterium Pseudoalteromonas in a fermenter, breaking the cells open, extracting the contents and filtering the liquid. It is a microbial ferment product with an undefined mixed composition.
CosIng definition: Pseudoalteromonas Ferment Lysate Extract Filtrate is a filtrate of the extract of the lysed product obtained through fermentation by the microorganism, Pseudoalteromonas, Pseudoalteromonadaceae.
