Result Qualified
(1) EDTA-2Na can be used in detergents, liquid soaps, shampoos, agriculture. Chemical spray, color photosensitive material processing bleaching fixer, water purifying agent, pH adjuster, cation gel, etc. 

(2) In the redox initiation system for styrene-butadiene rubber polymerization,  EDTA-2Na is used as a component of the active agent to mainly complex ferrous ions and control the polymerization rate. This product is low in toxicity, and the oral LD50 of rats is 2000 mg/kg. Used as a chelating agent for metal ions. 

(3) Test calcium, magnesium, etc.  EDTA-2Na is used in the pharmaceutical industry, color development, smelting of rare metals, etc. EDTA-2Na is an important complexing agent and metal masking agent.

(4) EDTA-2Na is used as an aminocarboxy complexing agent for the determination of calcium, magnesium and other metals.  EDTA-2Na is also used as a metal masking agent, color developer.  EDTA-2Na is used in the pharmaceutical industry and the smelting of rare metals.
(5) EDTA-2Na is also used as a cosmetic anti-oxidation synergist.  EDTA-2Na is a metal ion chelating agent and has the same effect as EDTA, but it has a wider application range. Cosmetic raw materials contain trace amounts of metal ions and can be used in the production, storage and transportation of metal containers.
