Product Description

EDTA Disodium, also known as Disodium EDTA or EDTA-2Na, is a chelating agent widely used to bind metal ions and control their effects in industrial processes, food formulations, and pharmaceutical applications. By forming stable complexes with metal ions such as calcium, magnesium, iron, and copper, it helps improve formulation stability, reduce metal-related interference, and support consistent product performance.

KhonorChem offers EDTA Disodium in three grades: Industrial Grade, Food Grade, and Pharmaceutical Grade, catering to different application requirements and quality standards.

Applications

Industrial Grade EDTA Disodium

Industrial Grade EDTA Disodium is widely used in processes where metal ion control is important.

• Water Treatment: Helps bind metal ions and control metal-related interference in water treatment processes.

• Industrial Cleaning: Supports the control of metal deposits in selected cleaning formulations.

• Textile Processing: Helps control metal ions that may affect dyeing, bleaching, and other wet-processing operations.

• Detergents and Cleaning Products: Functions as a chelating agent in suitable industrial cleaning formulations.

• Chemical Manufacturing: Used in industrial formulations and processes requiring metal ion sequestration.

Food Grade EDTA Disodium

Food Grade EDTA Disodium is intended for food applications where its use is authorized by applicable regulations.

• Food Stabilization: Helps control metal-catalyzed reactions in permitted applications.

• Processed Foods: May be used in specific food categories to support stability and quality retention.

• Sauces and Dressings: Can function as a chelating agent where permitted by local regulations.

• Beverages and Other Formulations: May be suitable for selected applications depending on the applicable food additive requirements.

Permitted uses and maximum use levels vary by country and food category. Food-grade status does not automatically authorize use in every food product or market.

Pharmaceutical Grade EDTA Disodium

Pharmaceutical Grade EDTA Disodium is intended for pharmaceutical-related applications requiring defined quality specifications and suitable documentation.

• Pharmaceutical Formulations: May be used as a chelating agent in selected formulations.

• Formulation Stability: Helps control trace metal ions that may affect the stability of certain ingredients.

• Selected Liquid Preparations: May be incorporated into specific formulations when supported by formulation requirements and applicable standards.

• Research and Development: Can be evaluated during pharmaceutical formulation development according to the required quality standard.

The suitability of pharmaceutical-grade EDTA Disodium depends on the specific formulation, intended use, and applicable pharmacopeial or regulatory requirements. USP, EP, or other pharmacopeial compliance should be confirmed through supporting documentation.

Advantages

• Effective Chelation: Binds various metal ions and helps control their effects in industrial processes and formulations.

• Three Grade Options: Industrial, food, and pharmaceutical grades are available for different application requirements.

• Broad Application Potential: Suitable for evaluation in water treatment, industrial cleaning, textile processing, permitted food applications, and selected pharmaceutical formulations.

• Grade-Specific Documentation: Product specifications and supporting documents can be provided according to the selected grade and availability.

• Flexible Application Support: Customers can select the appropriate grade based on technical requirements, intended use, and destination market.

Packaging & Storage

Packaging: Common packaging options include 25 kg bags, subject to product grade and supplier availability. Other packaging options may be available upon request.

Storage Conditions:

• Store in a cool, dry, and well-ventilated area.

• Keep the packaging tightly sealed when not in use.

• Protect the product from moisture and contamination.

• Follow the handling and storage precautions specified in the product SDS/MSDS.

Shelf Life: Refer to the product label or supplier documentation for the shelf life of the specific grade supplied.

Regulatory Status

The regulatory status of EDTA Disodium depends on the product grade, chemical form, manufacturing source, intended application, and destination market.

Industrial Grade is intended for suitable industrial applications. Food Grade should meet the relevant food-grade requirements and comply with applicable food additive regulations for the intended market. Pharmaceutical Grade should meet the quality standards required for its intended pharmaceutical application.

Certifications, registrations, and compliance statements depend on the specific product and supporting documentation. Please confirm the required standard and destination market when requesting a quotation.
