Product Description of Glycolic Acid CAS#79-14-1
Glycolic acid is the smallest alpha-hydroxy acid (AHA) and is widely used in skincare formulations to enhance skin appearance and texture. It helps reduce wrinkles, acne scars, and hyperpigmentation. In the textile industry, it functions as a dyeing and tanning agent. It is also applied as a flavoring agent in food processing and as a skincare ingredient in pharmaceutical products. Additionally, it can be incorporated into emulsion polymers, solvents, and ink additives to improve flow properties and provide gloss. Furthermore, glycolic acid serves as an important intermediate in organic synthesis, including redox reactions, esterification, and long-chain polymerization processes.
