Applications of Tetrasodium EDTA
- Cleaning products
- Personal care products
Removes calcium oxalate, calcium sulfate, calcium carbonate, barium sulfate, and other type scales from process equipment. Used in radioactive decontamination processes.
I & I Cleaners:
Dissolves scale, prevents scale formation, improves detergency of surfactants. Prevents turbidity in concentrated liquid cleaners and shampoos. Minimizes effects of polyvalent metal ions on emulsions, lubricants and polishes.
Removal of oxide films from metal articles; alkaline derusting; antistreak agents for pickling baths; alkaline degreasing.
Controls metal ions in scouring, boil-off, bleaching, dyeing, stripping, and finishing operations. Protects fluorescent whitening agents from metal catalyzed oxidation and degradation. Protects dyes from color change.
Improves efficiency of hydro bleach; reduces metal catalyzed brightness reversion. Used in descaling process equipment. Protects dyes from precipitation with metals.
Prevention of calcium and magnesium soap formation; improve detergency of soaps and detergents. Stabilizes perborate and percarbonate bleaches.
Enhanced Oil Recovery:
Boiler steam flooding; added to preflush or caustic flush plug to prevent magnesium and calcium silicate precipitates; ties up hardness ions that may cause precipitation of expensive surfactants during micellar flooding.
