How we scored it
Fermentation-derived cellulose; this site's method cellulose/fermentation convention = 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
Produced by fermenting the bacterium Gluconacetobacter xylinus on a sugar-based medium, which secretes cellulose nanofibers. A biotechnological process with no petrochemical route.
In plain English
A natural cellulose fiber network produced by fermenting bacteria on sugar. It's used to thicken formulas and form a protective film on skin.
CosIng definition: Microbial Cellulose is the Cellulose produced by Gluconacetobacter xylinus through fermentation.
