On glycolic acid
Glycolic acid, in the field of chemical industry, has a special status. It is widely used and involves a wide range of fields, which is quite complicated.

Wide application
In the daily chemical industry, glycolic acid is often found in skin care products. Because of its unique properties, it can effectively improve skin quality. It can gently exfoliate the exfoliation, causing the old cells on the surface of the skin to fall off, promoting the replacement of new cells, making the skin radiant, delicate and smooth. In the field of beauty and skin care, many skin rejuvenation products contain glycolic acid ingredients, which help people pursue beautiful skin.

In industrial production, glycolic acid also has important uses. In terms of metal cleaning, it can react with dirt and oxides on metal surfaces, effectively clean metals, and is relatively less corrosive to metals, maintaining metal properties and ensuring the normal operation of industrial equipment.

Significant benefits
From a skin care perspective, glycolic acid can not only improve the appearance of the skin, but also has better mildness than other strong acid strippers. For people with sensitive skin, using products containing glycolic acid at a reasonable concentration can also achieve skin beauty effects and reduce the risk of discomfort such as allergies.

In industrial cleaning, glycolic acid can reduce environmental pollution due to its excellent cleaning ability and relatively environmentally friendly characteristics. Its biodegradability is good, and it can be gradually decomposed in the natural environment after use, which is in line with the current concept of green production.

Production method
Production of glycolic acid, there are various methods. One is the formaldehyde cyanoalcohol method, which uses formaldehyde and hydrocyanic acid as raw materials to generate glycolic acid through a series of reactions. Although this method is easy to obtain raw materials, hydrocyanic acid is highly toxic, and the production process needs strict safety control.

Another common method is the hydrolysis method of chloroacetic acid, which uses chloroacetic acid as the starting material to obtain glycolic acid through hydrolysis reaction. The process of this method is relatively mature, but the production process produces certain wastewater, which needs to be properly treated to meet environmental protection requirements.

Nowadays, with the development of science and technology, new production processes continue to emerge, aiming to improve the production efficiency of glycolic acid, reduce costs, and enhance the safety and environmental protection of the production process.
