Description
Magnesium gluconate (CAS 3632-91-5) is the magnesium salt of gluconic acid, commercially known under trade names including Almora and Menesia. It carries no assigned E-number and is distinct from inorganic magnesium salts in its organic acid-based structure, which governs its solubility and bioavailability profile.
In food and nutrition applications, it functions as a magnesium source and pH buffer, moderating acidity in mineral-fortified products without precipitating at physiological pH ranges. In personal care formulations, it acts as a chelator that sequesters interfering metal ions and as a skin conditioner and protectant, stabilising emulsion systems and supporting barrier function.
Magnesium gluconate is available in food-grade and pharmaceutical-grade forms, with quality benchmarks including FCC and Ph.Eur. specifications. It is subject to REACH registration requirements for EU supply. The compound is classified under HS code 29181990 and is typically supplied in powder or crystalline form in standard bulk packaging.
