Trisodium EDTA (Trisodium Ethylenediaminetetraacetate) is a highly effective chelating agent that binds metal ions to prevent unwanted reactions in industrial processes. This white crystalline powder offers exceptional water solubility and maintains a pH of 10-12 in 1% solution, making it ideal for applications requiring metal ion control and scale prevention.
Key Applications
Water Treatment: Controls metal ions that cause scale buildup and equipment corrosion in industrial water systems
Cleaning Products: Enhances cleaning efficiency by sequestering calcium and magnesium ions that interfere with detergent performance
Textile Processing: Prevents metal-catalyzed degradation of fabrics and dyes during manufacturing processes
Industrial Equipment: Removes mineral scale deposits from boilers, cooling towers, and heat exchangers
Safety & Handling
Trisodium EDTA is non-flammable with no flash point concerns. Standard personal protective equipment including safety glasses, gloves, and dust masks should be worn when handling the powder to prevent inhalation or skin contact. Ensure adequate ventilation in work areas to minimize dust exposure. The alkaline nature of solutions requires careful handling to avoid skin and eye irritation.
Storage & Shelf Life
Store in tightly sealed containers in a cool, dry location away from moisture and incompatible materials. Avoid storage near strong acids which can react with the alkaline compound. When properly stored, Trisodium EDTA maintains its effectiveness for extended periods. Keep containers elevated and protected from flooding to prevent contamination.

Trisodium EDTA (C10H13N2Na3O8) is the trisodium salt of ethylenediaminetetraacetic acid and acts as a chelating agent. It is used in industrial applications and laboratories for metal ion sequestration, scale control, corrosion inhibition, cleaning, and analytical titrations.
How should trisodium EDTA be stored and what is its typical shelf life?
Store trisodium EDTA in a cool, dry, well-ventilated area in tightly closed original containers away from moisture and strong oxidizers. Under recommended storage conditions the solid typically retains specification for 1–3 years; check the supplier COA for exact shelf-life information.
What safety precautions and personal protective equipment (PPE) are recommended when handling trisodium EDTA?
Use chemical-resistant gloves, eye protection, and protective clothing to avoid skin and eye contact, and handle in a well-ventilated area or with local exhaust. In case of contact, flush with water and seek medical attention as indicated; always refer to the product SDS for complete first-aid and hazard information.
How do different concentrations of trisodium EDTA affect its performance?
Concentration affects chelation capacity, ionic strength and pH of solutions: higher concentrations increase metal-binding capacity but may change formulation properties and compatibility. Suppliers offer the salt as solid (powder) and as prepared aqueous solutions at various wt%—select concentration based on required chelation strength and process conditions.
What documentation is available for trisodium EDTA?
Common documents include Safety Data Sheets (SDS), Certificates of Analysis (COA), Technical Data Sheets (TDS) and product specifications; regulatory compliance documents (e.g., REACH, TSCA statements) may be available on request. Ask your supplier for the most current documentation for the specific lot and grade.
How is trisodium EDTA shipped and what packaging options are typical?
Trisodium EDTA is typically shipped as a solid powder or as aqueous solution in fiber drums, polyethylene drums, multi-wall paper bags with liners, or bulk totes, depending on quantity and grade. Shipping classification follows local transport regulations—consult the SDS and carrier for any special handling or restrictions.
Is trisodium EDTA compatible with common materials of construction?
It is generally compatible with most plastics (HDPE, PP) and stainless steels for short- to medium-term contact, but because it chelates metal ions it can mobilize or accelerate corrosion in soft metals (copper, brass, galvanized steel) and should be avoided in long-term storage in metal containers. Also avoid contact with strong oxidizers and consult compatibility charts for specific systems.
What are the key technical specifications for trisodium EDTA?
Typical specifications include formula C10H13N2Na3O8, molecular weight ≈ 358.2 g/mol, appearance as a white crystalline powder, high water solubility and typical assay/purity ≥98–99% for reagent/technical grades. Exact specs (assay, moisture, heavy metals) vary by supplier and grade—refer to the product COA.
Which industries and applications commonly use trisodium EDTA?
Common industries include water treatment, metal finishing, detergents and cleaners, textiles, pulp and paper, and laboratories for analytical chelation and buffer preparation. It is used wherever controlled sequestration of divalent and multivalent metal ions is required in industrial or research processes.
How can I purchase trisodium EDTA and what availability should I expect?
Trisodium EDTA is available from chemical distributors and manufacturers in lab, technical and bulk grades and in various pack sizes; lead times and minimum order quantities depend on supplier and region. For purchasing, request the product grade, COA, SDS and pricing from your preferred supplier and confirm availability and delivery timelines.
