Product Details

Glycolic acid is the smallest alpha-hydroxy acid (AHA). It is mainly supplemented to various skin-care products to improve the skin’s appearance and texture. It can also reduce wrinkles, acne scarring, and hyperpigmentation. In textile industry, it can be used as a dyeing and tanning agent. It can also be used as a flavoring agent in food processing, and as a skin care agent in the pharmaceutical industry. It can also be added into emulsion polymers, solvents and ink additives to improve flow properties and impart gloss. Moreover, it is a useful intermediate for organic synthesis including oxidative-reduction, esterification and long chain polymerization.
