Description
Potassium gluconate (CAS 299-27-4, EC 206-074-2) is the potassium salt of gluconic acid, supplied as a crystalline powder under synonyms including potassium D-gluconate and monopotassium D-gluconate. It carries no E-number designation and is classified under HS code 29181600.
In food and nutrition, it serves as a potassium fortification agent and pH buffer, releasing potassium ions in aqueous systems while moderating acidity. In personal care formulations, it functions as a chelator that binds calcium and magnesium ions to improve preservative efficacy, and as a skin conditioner that supports the moisture-retention capacity of the stratum corneum.
Potassium gluconate is available in food-grade and pharmaceutical-grade forms, with compliance to FCC, Ph.Eur., and USP monographs depending on grade. It falls under REACH registration requirements for EU supply. Standard packaging includes 25 kg bags or fiber drums, with bulk options available on request.
