Glycolic acid (hydroacetic acid or hydroxyacetic acid); chemical formula C₂H₄O₃ (also written as HOCH₂CO₂H), is the smallest α-hydroxy acid (AHA). This colorless, odorless, and hygroscopic crystalline solid is highly soluble in water. It is used in various skin-care products. Glycolic acid is found in some sugar-crops. A glycolate or glycollate is a salt or ester of glycolic acid.
