Food Grade Disodium Edta

Basic Product Parameters

This product is disodium EDTA dihydrate with a fixed molecular formula of C10H14N2Na2O8·2H2O and a molecular weight of 372.24. The registered CAS number for industrial identification and traceability is 6381-92-6, supporting standard industrial batch inspection and customs declaration procedures.

Physical & Chemical Properties

The product presents in two stable physical forms: white crystalline particles and white to off-white crystalline powder, with no odor and no taste. It features slight hygroscopicity under conventional ambient storage conditions. In terms of solubility, it delivers high solubility in water and is practically insoluble in ethanol solvent. A 5% aqueous solution of this product maintains a stable pH value ranging from 4.0 to 6.0 at room temperature.

The core technical characteristic lies in its high-intensity complexation performance. The product can stably bind with various heavy metal ions in solutions to form water-soluble, stable complex compounds. This chemical property enables effective removal of free heavy metal ions and eliminates adverse impacts and quality risks caused by heavy metal contamination in production systems.

Industrial Applications

Based on its stable complexation, anti-oxidation and stabilizing properties, the product serves four core functional roles in industrial production. It acts as a standard chelating agent for metal ion control, a preservative for material shelf-life stabilization, an antioxidant to suppress oxidative deterioration of raw materials, and a processing aid to optimize production system stability. It is widely adaptable to conventional industrial production scenarios that require heavy metal ion isolation and product stability maintenance.

Packaging Specification

The product adopts a double-layer sealed packaging structure for quality protection. The inner layer is a food-grade and industrial-grade compatible polyethylene bag for moisture isolation and dust prevention, and the outer layer is a high-strength compound plastic woven bag for mechanical damage resistance. The standard net weight of each finished package is 25kg, complying with general industrial bulk procurement and warehousing specifications.

Storage & Transportation Requirements

Finished products shall be stored in dry, ventilated and flat warehouses with stable ambient temperature and humidity to avoid moisture absorption and product performance changes. During road and logistics transportation, consignments must be kept away from high-temperature sources and humid environments. Manual and mechanical unloading shall be conducted gently to prevent package breakage and material leakage.

For safety and quality control, this product must be stored and transported in isolated batches from all toxic substances to avoid cross-contamination and ensure product purity and application safety.
