High-Density Chitosan Chemical name: β-(1→4)-2-Amido-2-deoxy-D-glucosamine hydrochloride Molecular formula: (C6H11NO4)N This product is non-toxic, odorless, off-white or slight yellow powder, and soluble in acid, insoluble in water and base or normal organic solutions. Dissolved in 185°C. Applications: The gastric soluble time for normal chitosan products is nearly two hours with low density, which will require to take several pills (5 ~ 6 grain) of capsules to have good health care function. High density chitosan has 2 ~ 3 times higher density than the ordinary ones, which means the capacity for oil absorption is 3 times of ordinary chitosan under the same volume, and 1 pill of the capsule will be just fine for each time. The gastric soluble time of high density chitosan is short, which can be quickly dissolved in acid conditions. When passing through the gut in the alkaline conditions after adsorption of fat and cholesterol, the floe won’t be absorbed but cleaned out of the body, so as to reduce weight and blood fat to maintain health.
