Disodium Edetate (EDTA Disodium Salt)     
High-Purity Chelating Agent for Multisector Industrial Applications   

Disodium Edetate , systematically named disodium 2,2',2'',2'''-(ethane-1,2-diyldinitrilo)tetraacetate dihydrate, is a white crystalline powder or granules with excellent water solubility (>100 g/L at 25°C). This dihydrate form exhibits stability under ambient conditions, non-hygroscopic properties, and weak acidity in aqueous solutions (pH 4-6 for 1% solution). Compliant with USP, EP, and FCC standards, it is a versatile chelator with low toxicity and broad regulatory acceptance.  

 Key Industrial Applications :   
1.   Food Industry  :  
   - Approved preservative (E385) for color retention in canned foods, beverages, and dairy products.  
   - Antioxidant stabilizer to prevent lipid oxidation in oils and sauces.  
2.   Pharmaceuticals  :  
   - Anticoagulant in blood collection tubes (EDTA dipotassium compatibility).  
   - Active ingredient in heavy metal detoxification drugs.  
3.   Cosmetics  :
