Description
Gluconic acid (CAS 526-95-4) is a mild organic acid derived from the oxidation of glucose, commercially available under trade names including Gluconal GA-50 and commonly referred to as maltonic acid or glyconic acid. It carries no E-number designation and is identified under EC 208-401-4.
In water treatment, gluconic acid sequesters calcium, magnesium, and iron ions by forming stable chelate complexes, preventing scale formation in industrial systems. In personal care formulations, it functions as a pH buffer and humectant, conditioning skin by attracting moisture while maintaining formula stability across a broad pH range.
Gluconic acid is supplied as a 50% aqueous solution or as crystalline powder, with grades available to FCC, Ph.Eur., and food-contact standards. The product falls under REACH regulation and is classified under HS code 29181600. Packaging options typically include IBC containers and drums for bulk procurement.
