Description

Sodium Glucoheptonate is the sodium salt of glucoheptonic acid, a versatile and highly effective chelating agent derived from carbohydrate chemistry. Its primary value lies in its powerful yet safe sequestering ability for polyvalent metal ions, particularly calcium, magnesium, and iron, across a wide pH range. This makes it an essential component for formulators and manufacturers in industries such as cleaning, personal care, and construction, where controlling water hardness and preventing scale formation is critical for product performance and process efficiency.

Application

• Industrial & Institutional (I&I) Cleaners: Key chelant in alkaline and acidic detergents, bottle washing compounds, and metal cleaning formulations to prevent soap scum and mineral scale.
• Personal Care Products: Used in shampoos, liquid soaps, and creams as a gentle yet effective sequestrant to improve clarity, stability, and shelf-life.
• Construction Chemicals: Acts as a setting retarder and water reducer in cement and concrete admixtures, improving workability and final strength.
• Textile Processing: Employed in bleaching, dyeing, and finishing baths to complex metal ions that could cause fabric discoloration or catalytic damage.
• Pulp & Paper Industry: Enhances the efficiency of hydrogen peroxide bleaching by stabilizing the peroxide and sequestering metal catalysts.
• Agriculture: Component in micronutrient fertilizers and agrochemical formulations to improve nutrient availability and compatibility.
• Water Treatment: Used in boiler and cooling water systems to control scale and corrosion by binding calcium and magnesium ions.
• Metal Surface Treatment: Chelating agent in electroplating and metal finishing baths to maintain solution stability and deposit quality.

Quality Control

Our Sodium Glucoheptonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and heavy metal content are provided with every shipment to guarantee traceability and consistency for your production processes.

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 when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced flowability.
