NAGLUSOL^®

General information

NAGLUSOL^® is a 60 % solution of equal parts of gluconic acid and sodium gluconate.

Like its components, NAGLUSOL^® is an excellent chelating agent, non-corrosive, non-toxic and easily biodegradable (98 % after 2 days). In addition, it combines the advantages of sodium gluconate and gluconic acid without their drawbacks.

Being a blend of sodium gluconate and gluconic acid, the principal property of NAGLUSOL^® is obviously its excellent chelating power for calcium, iron, copper, aluminium and other heavy metals, especially in alkaline and concentrated alkaline solutions.

But it has also additional properties that set it apart from its components:

• A high concentration
  NAGLUSOL^® has a concentration that is 1.6 time as high as the concentration of a saturated sodium gluconate solution at room temperature. Thus, it provides less dilution of other additives at incorporation into formulations.
• A low freezing point
  Indeed, gluconic acid is known for its tendency to crystallise at temperatures below +10°C. NAGLUSOL^® remains stable down to -10°C although its concentration is even higher than that of gluconic acid.

Furthermore, NAGLUSOL^® is easy to use because it has a low viscosity in spite of its high concentration, and it allows to economise caustic soda in applications requiring both a gluconic acid and alkali solution.
