Sequestering Performance and Key Benefits
Dissolvine NA is a versatile sequestering agent, forming stable, water-soluble chelates with polyvalent metal ions across a wide pH range. Theoretical sequestering values (mg metal per g of product) include:
- Calcium: 90 mg/g (pH 5-14)
- Copper: 145 mg/g (pH 2-14)
- Ferric iron: 125 mg/g (pH 1-10)
- Magnesium: 55 mg/g (pH 6-11)
- Manganese: 125 mg/g (pH 3-13)
- Zinc: 150 mg/g (pH 2-13)
It is inherently biodegradable, with rapid biodegradation obtainable under slightly alkaline conditions, and a COD of approximately 560 mg/g according to the manufacturer’s data.
Typical Applications of Dissolvine NA
Per the manufacturer’s product data leaflet, it is used in numerous industries for control of hardness and heavy metal ions:
- Cleaning industry: hardness controller
- Detergents & soaps: stabilizer
- Disinfectant: potentiator
- Metal treatment: metal remover
- Oil field: scale dissolver
- Polymer processing: stabilizer
- Pulp & paper industry: bleach stabilizer
- Textile industry: bleach & dye stabilizer
These applications span our auxiliary agent category, where broad-pH-range chelation supports consistent process performance across detergent, metal treatment, and industrial formulations.
