Glycolic acid is the smallest α-hydroxy acid (AHA). This colorless, odorless, and hygroscopic crystalline solid is highly soluble in water. A water solution form is also available. Glycolic acid is slightly stronger than acetic acid due to the electron-withdrawing power of the terminal hydroxyl group. The carboxylate group can coordinate to metal ions forming coordination complexes. Of particular note are the complexes with Pb2+ and Cu2+ which are significantly stronger than complexes with other carboxylic acids.
This indicates that the hydroxyl group is involved in complex formation, possibly with the loss of its proton.
Under proper storage conditions, the shelf life is 36 months
