Description

Potassium D-Gluconate is the potassium salt of D-gluconic acid, a highly bioavailable and well-tolerated organic compound. This material serves as a superior source of potassium in applications where high solubility, neutral pH, and excellent biocompatibility are critical. It is essential for manufacturers in the pharmaceutical, food & beverage, and personal care industries seeking a high-purity, functional mineral supplement. Its favorable safety profile and stability make it a preferred choice for formulating advanced nutritional and therapeutic products.

Application

• Pharmaceutical Formulations: Used as a potassium supplement in oral rehydration salts, effervescent tablets, and liquid multivitamin/mineral preparations.
• Food & Beverage Fortification: Acts as a mineral nutrient and pH buffer in sports drinks, infant formula, dietary supplements, and functional foods.
• Personal Care & Cosmetics: Functions as a skin-conditioning agent and humectant in lotions, creams, and other dermatological preparations.
• Animal Nutrition: Incorporated into feed premixes and veterinary products as a source of essential potassium for livestock and pets.
• Biotechnology & Cell Culture: Serves as a component of buffer systems and nutrient media in microbiological and cell culture applications.
• Industrial Applications: Utilized in metal surface treatment solutions and as a setting retarder and plasticizer in certain concrete admixtures.

Quality Control

Our Potassium D-Gluconate is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and composition. We can supply material compliant with relevant standards such as USP, FCC, and Ph. Eur. upon request. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking.
