Description

D-Gluconic Acid is a multifunctional organic acid valued for its excellent chelating, mild acidic, and sequestering properties. This versatility makes it a critical intermediate and additive across diverse industrial and consumer-facing sectors. Key industries that rely on this compound include food & beverage, pharmaceuticals, personal care, and industrial cleaning. Its ability to form stable complexes with metal ions under alkaline conditions is a primary driver for its widespread commercial use.

Application

• Food & Beverage Additive: Used as an acidity regulator, sequestrant, and leavening agent in baked goods, beverages, and dairy products.
• Pharmaceutical Intermediate: Serves as a key starting material in the synthesis of calcium and iron gluconate supplements and other therapeutic agents.
• Industrial Cleaning & Derusting: An effective, biodegradable component in alkaline derusting and cleaning formulations for metals, prized for its non-corrosive nature.
• Personal Care & Cosmetics: Functions as a pH adjuster, chelating agent, and skin conditioning agent in creams, lotions, and oral care products.
• Concrete Admixture: Acts as a setting retarder in concrete, allowing for better workability and placement in warm climates or large pours.
• Textile & Paper Processing: Utilized as a chelant in peroxide bleaching baths for textiles and pulp to improve brightness and protect fibers.
• Water Treatment: Helps control scale formation in water systems by sequestering calcium and magnesium ions.
• Agricultural Applications: Used in certain fertilizer and pesticide formulations to improve nutrient availability and stability.

Quality Control

Our D-Gluconic Acid is manufactured under a strict quality management system. We offer grades suitable for food (FCC), pharmaceutical, and technical applications, with specifications tailored to meet the rigorous demands of each sector. Every batch is accompanied by a comprehensive Certificate of Analysis (COA) to ensure traceability and compliance with agreed specifications, including purity, identity, and impurity profiles.

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); ensure the original container is securely sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
