Chemical Product Description & Applications
Sodium glucoheptonate is a sugar-derived complexing agent used to keep suitable metal ions in solution. Its carboxylate and multiple hydroxyl groups form soluble complexes, reducing interference from hardness and trace metals. This helps maintain cleaning performance and bath stability in industrial aqueous formulations.
The selected product is a liquid industrial grade at nominal 50% concentration, consistent with the commercial solution form. It is distinct from sodium gluconate and from crystalline glucoheptonate grades with separately specified identity. In cleaning and textile processes, the main contribution is sequestration rather than direct detergency. In formulated process fluids, it can also help maintain metal-ion availability without precipitation.
Typical Applications
- Alkaline industrial cleaners: Used to manage hardness and metal-ion interference in equipment, bottle or other suitable hard-surface cleaning formulations.
- Textile wet-processing baths: Used as a sequestrant in compatible scouring, washing or other aqueous processes where trace metals can disrupt performance or appearance.
- Industrial metal-ion formulations: Used in appropriate process solutions to maintain selected metals in soluble complexed form and limit unwanted precipitation.
