Description

Calcium Glucoheptonate is a water-soluble, organic calcium salt derived from gluconic acid. This compound serves as a highly bioavailable and stable source of calcium, making it a critical ingredient for applications requiring precise mineral fortification and chelation. It is primarily utilized by manufacturers in the pharmaceutical, food & beverage, and personal care industries for its superior solubility and compatibility.

Application

• Pharmaceutical & Nutraceutical Formulations: Used as a calcium source in tablets, capsules, and liquid supplements due to its excellent bioavailability and neutral taste.
• Food & Beverage Fortification: Acts as a mineral fortifier in dairy products, beverages, baked goods, and nutritional powders, where solubility and clarity are essential.
• Personal Care & Cosmetics: Incorporated into creams, lotions, and oral care products for its skin-conditioning and remineralizing properties.
• Technical & Industrial Applications: Functions as a sequestrant and stabilizer in water treatment and as a component in certain chemical synthesis processes.
• Animal Feed & Nutrition: Employed as a dietary calcium supplement in premixes and feed formulations to support animal bone health and development.

Quality Control

Our Calcium Glucoheptonate is produced under a quality management system and undergoes rigorous analytical testing to ensure it meets stringent specifications for purity, identity, and safety. We can supply material compliant with relevant standards such as FCC (Food Chemicals Codex) and USP-NF (United States Pharmacopeia) where applicable. A comprehensive Certificate of Analysis (COA) is provided with each batch to guarantee traceability and compliance.

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 material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture which may lead to caking or degradation.
