Overview
Sodium glucoheptonate is a highly effective chelating agent designed for the dissolution of iron and other metal oxides, as well as for the removal of rust and scale. Its strong complexing ability makes it a valuable additive in various industrial cleaning and textile processes.

Applications

• Industrial cleaning: Dissolves iron oxides and scale deposits in boilers, heat exchangers, and pipelines.

• Rust and scale removal: Used in descaling formulations for metal surfaces.

• Textile industry: Employed in bleaching and dyeing processes to sequester metal ions that may interfere with color quality and fiber strength.

• Water treatment: Helps control metal ion concentrations in industrial water systems.

• Detergents and cleaners: Enhances the performance of cleaning formulations by binding hardness ions and preventing redeposition.

Key Benefits

• Excellent chelation of Fe³⁺ and Ca²⁺ ions.

• Biodegradable and environmentally safer than many synthetic chelators.

• Effective across a broad pH range.

• Stable under normal storage conditions.

Handling and Storage
Store in a cool, dry place away from moisture and direct sunlight. Keep containers tightly sealed to prevent caking. Use appropriate personal protective equipment (gloves, dust mask) when handling.

Packaging
Available in 25 kg bags, 50 kg drums, and custom packaging upon request.

Quality Assurance
Each batch is tested for purity, moisture, pH, chloride, sulfate, and chelating capacity to ensure consistent product quality.
