Dissolvine NA2 is a high-purity sequestering agent based on ethylenediaminetetraacetic acid (EDTA), disodium salt, dihydrate, supplied by Nouryon under the Dissolvine brand. For industrial buyers sourcing a chelating agent that forms stable, water-soluble complexes with polyvalent metal ions across a wide pH range, Dissolvine NA2 offers documented purity, solubility, and sequestering performance confirmed on the manufacturer’s published product data sheet. This guide summarizes the verified specifications, applications, and sourcing considerations buyers need before placing an order.
What Is Dissolvine NA2?
Dissolvine NA2 is the chemical name Ethylenediaminetetraacetic acid, disodium salt, with CAS number 6381-92-6 (dihydrate form), a molecular weight of 372.2, and molecular formula EDTA-Na2H2.2H2O. It belongs to the chelate chemical family and is a sequestering agent of high purity that forms stable, water-soluble chelates with polyvalent metal ions over a wide pH range, according to the manufacturer’s technical documentation.

Physical Characteristics
| Property | Value |
|---|---|
| Bulk density, tapped | ~800-1000 kg/m³ |
| Bulk density, untapped/poured | ~500-700 kg/m³ |

Sequestering Values (Approximate, Theoretical)
| Metal Ion | pH Range | Sequestering Value |
|---|---|---|
| Calcium | 5-14 | 105 mg metal/g |
| Copper | 2-14 | 170 mg metal/g |
| Ferric | 1-10 | 150 mg metal/g |
| Magnesium | 6-11 | 65 mg metal/g |
| Manganese | 3-13 | 145 mg metal/g |
| Zinc | 2-13 | 175 mg metal/g |
These sequestering values give formulators a reference point when estimating dosage for a given hardness or metal-ion load, though actual performance in a specific formulation should always be confirmed with bench trials, since real system pH, competing ions, and other formulation components can affect sequestering efficiency.
