Products Description of Glycolic Acid CAS#79-14-1
Glycolic acid is an important chemical product and a key intermediate in organic synthesis. It is widely applied in industries such as organic synthesis, cleaning, electroplating, textiles, leather processing, and sterilization. In recent years, research has shown that polymers derived from glycolic acid are biodegradable, helping to overcome the poor degradability of traditional plastics and enabling broad use in fields such as medicine, packaging, and many other applications.

Product Application of Glycolic Acid CAS#79-14-1
Glycolic acid is a key chemical raw material and is used in the production of ethylene glycol, menthyl glycolate, and quinine glycolate.
It is also employed in the preparation of tanning agents, hair dyes, leather and fiber dyes, adhesives, metal chelating agents, petroleum demulsifiers, electroplating agents, aluminum etching solutions, cellulose fabric cross-linking agents, and stainless steel electropolishing agents.
Additionally, glycolic acid serves as a cleaner and disinfectant in food processing facilities and livestock environments, functions as a boiler anti-scaling agent, acts as a surface treatment agent for copper and other metals, and is used in the formulation of skincare cosmetics.
