How we scored it
Fermentation gum from natural sorbitol substrate; fermentation-gum 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 microbial fermentation of sorbitol to yield this deacetylated branched polysaccharide gum. A biotechnological process with no petrochemical route.
In plain English
A film-forming gum made by fermenting natural sugar alcohol with microorganisms, used to condition skin. It uses a similar biotech process to other biosaccharide gums.
CosIng definition: Biosaccharide Gum-4 is a fermentation gum derived from sorbitol. It is a deacetylated branched polymer consisting of L-fucose, 2-D-glucose and glucuronic acid repetitive units
