On the matter of glycolic acid
Glycolic acid is quite important in various fields of chemical industry. It is active and has a wide range of uses.

Looking at its physicochemical properties, glycolic acid has unique characteristics. Its shape or crystalline state, its color is white, and its taste is slightly acidic. In water and alcohol solvents, it is easily soluble and fast. Because of its molecular structure, it has hydrophilic groups and can form hydrogen bonds with water molecules, so it is well soluble. And its acidity is moderate, compared with other strong acids, it is mild and additive, and it can be used in many reactions, and its controllability is excellent.

As for the preparation method, it is parallel in many ways. First, it is obtained by catalytic reaction based on formaldehyde and carbon monoxide. The raw materials are easy to obtain in this way, and the process is gradually maturing. However, the reaction conditions are harsh, and specific catalysts and pressure and temperature environments are required to promote the efficient and directional reaction. Second, the fermentation method of sugar raw materials is prepared by biological means, which has the characteristics of green and environmental protection. However, the screening and cultivation of strains are the key, and the fermentation conditions are finely regulated to ensure the yield and purity.

Glycolic acid is widely used in the field of medicine and can be used to make pharmaceuticals. Because of its gentle peeling ability, it helps the skin's keratin renew, and is often used in skin treatment. It has significant effect on acne, pigmentation and other diseases. In daily chemical products, it is also a frequent customer. Adding skin care products can increase skin moisture and luster, exfoliate without hurting the skin, and make the skin delicate and smooth. In the industrial industry, metal cleaning is also used. It can remove rust and unkempt on the surface of the metal, and has weak corrosion to the metal, keep the metal material intact, and prolong the life of the device.

Glycolic acid has a key position in the chemical, pharmaceutical, daily chemical, industrial and other industries. With the progress of science and technology, in-depth research and development, its potential will be more obvious, and it will contribute to the development of various fields.
