Mannitol in skin care products play a moisturizing role. Mannitol is a polyol or sugar alcohol, its natural products are widely available in plants, algae, edible fungi and lichens and other organisms. Because of its special physical and chemical properties, mannitol has a wide range of applications in the food, pharmaceutical and chemical industries.

Mannitol is a six-carbon sugar alcohol, can be produced by the catalytic hydrogenation of fructose, low hygroscopicity, often used as a powder sprinkler in the manufacture of gummies to avoid adhesion with the manufacturing equipment, packaging machinery, but also used as a component of the plasticizing system, so that it maintains its soft properties. It is also used as a diluent or filler for sugar tablets and as a chocolate-flavored coating for ice cream and candy.

It has a pleasant flavor, does not fade at high temperatures and is chemically inactive. Its pleasant flavor and texture masks vitamin, mineral and herbal odors. It is a good low-calorie sweetener, anti-sticky agent for gummies and candies, nutritional supplement and tissue improver, and moisturizer.

The properties of mannitol:

Mannitol, also known as mannitol, molecular formula for C6H14O6, relative molecular mass of 182.17, colorless to white acicular or rhomboid columnar crystals or crystalline powder. It is odorless and has a cool sweet taste. The sweetness is about 57%~72% of sucrose.

Every gram produces 8.37J heat, about half of glucose. Hygroscopicity is small, and post-water solution is stable. Stable to dilute acid and alkali. Not oxidized by oxygen in air. Soluble in water (5.6g/100mL,20℃) and glycerol (5.5g/100mL), slightly soluble in ethanol (1.2g/100mL), almost insoluble in most of other common organic solvents.
