D-mannitol, Mannitol Powder, a kind of sugar alcohol, is also known as d-mannitol.D- melitol;Manna melitol;D-mannitol;Acid;Piperan mannose sugar, etc.A colorless or white crystalline powder similar to sucrose that tastes slightly sweet.In medicine, food, feed, life science research have a role.

Mannitol Powder is widely found in many land and sea plants, such as olive and persimmon trees.Also abundant in some algae and fungi, it is chemically reduced by d-mannose and d-fructose and clinically used to reduce intracranial pressure and acute renal failure.
It's a very important essential drug on the who's list of important medicines.It is often used in plants to reduce osmotic
pressure.

Mannitol powder, D-Mannitol is a chemical substance with the molecular formula C6H14O6. Colorless to white needle-like or orthorhombic columnar crystals or crystalline powder. Odorless, with a cool sweetness. The sweetness is about 57% to 72% of sucrose. Produces 8.37J calories per gram, which is about half of glucose. Contains a small amount of Sorbitol. The relative density is 1.49. Optical rotation [α] D20º-0.40º (10% aqueous solution). Hygroscopicity is minimal. Aqueous solutions are stable. Stable to dilute acid and dilute alkali. Not oxidized by oxygen in the air. Soluble in water (5.6g/100ml, 20ºC) and glycerol (5.5g/100ml). Slightly soluble in ethanol (1.2g/100ml). Soluble in hot ethanol. Almost insoluble in most other common organic solvents. The pH of a 20% aqueous solution is 5.5 to 6.5.
