Tremella Fuciformis Polysaccharide isanewtypeofMoisturizing Agentextracted from tremella, it has good antioxidation and moisturizing properties. It is a kind ofwatersolublepolymer, theaveragemolecularweightisoveronemillionDa,and the molecular structure backbone is Mannan made up by alpha(1-3)- glycosidic bond composition, and the branched chain by glucuronic acid, xylose and fucose etc., the active part is common structural part of alpha(1-3)- mannan.
It's a kind of whiteoroff-white powder, which is easily absorbed and water soluble. And it is easily dispersed in glycerin and propylene glycol while being insoluble in organic solvents such as ethanol and acetone.
