It has an unpleasant odor, is a highly corrosive acid, easily deliquescent, and can form a paste when exposed to air. Slightly soluble in ethanol, ether, and benzene, can dissolve freely in water, and the aqueous solution is stable and does not deteriorate in air.

Acetic acid is an important raw material for fine chemicals, widely used in pharmaceuticals (mainly for broad-spectrum antibiotics such as amoxicillin, antihypertensive drug atenolol, cosmetic additives such as allantoin, high value-added aromatic aldehydes, p-hydroxybenzoic acid, etc.), water stabilizers, fragrances (ethylvanillin), pesticide intermediates, etc

application
1. Sodium tripolyphosphate can be used for the preparation of Vc phosphate, which not only has the effect of vitamin C, but also overcomes the disadvantage of vitamin C being easily oxidized by light, heat, and metal ions.
2. It can be used for the preparation of cross-linked starch. In industry, sodium tripolyphosphate is used as a cross-linking agent to prepare cross-linked starch, which has the characteristics of high efficiency, environmental protection, high conversion rate, and low cost. It is suitable for different product processing needs and has excellent product performance.
3. Sodium tripolyphosphate is an excellent inorganic surfactant due to its unique molecular structure.
4. Has strong chelating ability. It can form soluble complexes with metal cations such as calcium, magnesium, and iron dissolved in water, maintain inertness, and turn water into soft water, making it a water softener.
5. It has strong solubility and can dissolve many insoluble compound suspensions (including pigments); Make the dirt in the solution finely dispersed and not precipitate on the textile fibers. For solid particles, it can facilitate the generation of latex like liquid, promote particle dispersion, and maintain stability. When used together with detergents, it can accelerate particle dispersion speed and enhance washing effect; When used for viscous liquids, it can increase the fluidity of the liquid.
6. Sodium tripolyphosphate can be used as a buffering agent for hydrogen peroxide bleaching. As a component of detergent, it can maintain the pH of the detergent solution within the most suitable range. If used as a detergent for light metals, it can prevent the harm of alkali.
7. It is also the raw material for producing high-end toothpaste, and its function is equivalent to that of an abrasive. Medical research has shown that sodium tripolyphosphate also has the function of preventing and eliminating dental caries, and sodium tripolyphosphate is the most effective among all phosphates.

Moisturizing: Glucosamine promotes the synthesis of aquaporins, maintains osmotic balance, and brings the necessary moisture to skin cells. Aquaporins (AQPs) are membrane proteins that can selectively introduce or export moisture into and out of cells. AQP3 or AQP5 are mainly present in the epidermis of the skin. For example, AQP3 is used for transporting water and glycerol;
