How we scored it
Extract of a sugar-fed fungal fermentation: glucose-unit polysaccharide (pullulan or glucan) and culture metabolites are microbially made; medium and extraction 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
Produced by fermenting Aureobasidium pullulans, a yeast-like fungus, on sugar or starch-derived media, then extracting the culture broth; the main product is typically pullulan or glucan polysaccharide. No synthetic route exists.
In plain English
An extract of the liquid left after the yeast-like fungus Aureobasidium pullulans is grown on sugars in a fermentation tank. It is typically rich in glucose-based polysaccharides such as pullulan or glucan, and is used as a film-forming ingredient that leaves a thin film on skin or hair.
CosIng definition: Aureobasidium Pullulans Ferment Extract is the extract of Aureobasidium Pullulans Ferment
