Glycolic Acid, or hydroxyacetic acid, is a white crystalline solid that is easily solubilized in water to form a clear, odorless solution. Structurally, it is similar to acetic acid but with a hydroxylated methyl group, making it the smallest alpha-hydroxy acid (AHA). The term “lab grade” implies intermediate purity only; this product is not subject to the rigorous standards set for analytical or food grade reagents.
