Product Application of Glycolic Acid CAS#79-14-1
Glycolic acid acts as an essential chemical feedstock, applied in the manufacture of ethylene glycol, menthyl glycolate and quinine glycolate.
It is also utilized to synthesize tanning agents, hair colorants, leather and fiber dyes, adhesives, metal chelators, petroleum demulsifiers, electroplating additives, aluminum etching solutions, cross-linking agents for cellulosic fabrics, as well as electropolishing agents for stainless steel.
Furthermore, glycolic acid functions as a cleaning and sanitizing agent for food-processing plants and livestock breeding sites, a boiler antiscaling additive, a surface treatment agent for copper and other metals, and an ingredient in skin-care cosmetic formulations.
