Product Description EDTA-2NA and EDTA-4NA are white crystal powders with two crystals of water,easy to lose crystal water when dried and easy to soluble in water,but hard to soluble in organic solvents like alcohol or ethyl ether.The pH value of 5%(25 °C ) aqueous solution is 4.0~6.0.EDTA-2Na is used in detergent, liquid soap, shampoo, agricultural chemicals,fixer solutions for the development of color film, water cleaner, PH modifier.Test itemsStandard indicatorsTest resultsAssay %99.0 Min99.2 Chloride (Cl)%0.01 Max0.003 Sulfate(SO4)Content%0.05 Max0.01 Iron (Fe )%0.001 Max0.0001 Lead(Pb)%0.001 MaxNot FoundPH(50g/L,25oC) solution4.0-5.04.36 mgcaco3/g Chelating value265 Min266 AppearanceWhite crystalline powderWhite crystalline powderConclusionsQUALIFIEDQUALIFIEDApplications of EDTA-2Na and EDTA-4NaEDTA-2Na (Disodium EDTA) and EDTA-4Na (Tetrasodium EDTA) are widely used chelating agents known for their ability to bind metal ions. Their strong complexing capabilities make them valuable across a variety of industries:1. Water TreatmentEDTA-2Na and EDTA-4Na are used to remove hardness ions such as calcium and magnesium from water, improving the effectiveness of detergents and preventing scale formation.2. Cosmetics and Personal CareThese compounds are added to formulations such as shampoos, creams, and lotions to stabilize products by binding metal ions that could otherwise cause degradation, discoloration, or reduce shelf life.3. Food IndustryUsed as preservatives and stabilizers, especially to maintain color and prevent rancidity by binding trace metal catalysts. Regulatory limits apply depending on the region.4 AgricultureEDTA-2Na and EDTA-4Na serve as chelating agents for micronutrients such as iron, zinc, and manganese, improving nutrient availability and absorption in plants.5. Cleaning ProductsThey enhance the performance of industrial and household cleaners by softening water and improving the removal of dirt, scale, and rust.6. Laboratory and Analytical ChemistryUsed to titrate metal ions in complexometric titrations and as a stabilizer in various buffer solutions.Zibo Sangfei Chemical Co., LTD., located in the national chemical industry - Zibo city.
