Toxicological data

1, Acute toxicity: Oral administration to women TDLo: 1700mg/kg/D; Rat oral LD50: 15900mg/kg;p>1. Raw materials that can be used to produce vitamin C. Vitamin C can be produced from sorbitol through fermentation and chemical synthesis. It can also be used as a raw material for industrial surfactants to produce surfactants such as Span and Tween. Sorbitol has moisturizing properties and can replace glycerol in the production of toothpaste, cigarettes and cosmetics. Using sorbitol and propylene oxide as raw materials, polyurethane rigid foam with certain flame retardant properties can be produced. In the food industry, it can be used as a sweetener, humectant, chelating agent and tissue improver. In the pharmaceutical industry, the sorbitan ester produced by nitration of sorbitol is a drug for the treatment of coronary heart disease. Food additives, cosmetic raw materials, organic synthetic raw materials, moisturizers, solvents, etc.

2.Nutritive sweeteners, wetting agents, chelating agents and stabilizers. It is a special sweetener with moisturizing function. It is not converted into glucose in the human body and is not controlled by insulin, so it is suitable for people with diabetes. It can be used in pastries with a maximum usage of 5.0g/kg; in surimi and its products, the maximum usage is 0.5g/kg. It can also be used as a defoaming agent for sugar production, brewing and soy products. It can be used in appropriate amounts according to production needs. It can also be used to moisturize raisins, thicken and preserve the flavor of wine and refreshing drinks, as well as candies and chewing gum.

3.Synthetic resins and plastics, separation and analysis of low boiling point oxygen-containing compounds, etc. It is also used as gas chromatography stationary liquid, thickener, hardener, pesticide, etc.

4. Used as gas chromatography stationary liquid for low-boiling oxygen-containing compounds, amine compounds, nitrogen or oxygen heterocycles Separation analysis of compounds. Also used in organic synthesis.

5.Used as a moisturizing agent for toothpaste, cosmetics and tobacco. It is a substitute for glycerin, with milder moisturizing properties and better taste. Can be used with other moisturizers to achieve synergistic effects. It is also used in the pharmaceutical industry as a raw material for the manufacture of vitamin C.

6.Diuretic and dehydrating agent. It is used to treat cerebral edema and increased intracranial pressure, treat increased intraocular pressure in glaucoma, and is also used to treat edema and oliguria with normal heart and kidney function.
