EDTA Tetrasodium Salt Uses:
In industry, EDTA is mainly used to sequester metal ions in aqueous solution. In the textile industry, it prevents metal ion impurities from modifying colors of dyed products.
In a similar manner, EDTA is added to some food as a preservative or stabilizer to prevent catalytic oxidative decoloration, which is catalyzed by metal ions. The reduction of water hardness in laundry applications and the dissolution of scale in boilers both rely on EDTA and related complexants to bind Ca2 , Mg2 , as well as other metal ions.
In shampoos, cleaners and other personal care products EDTA salts are used as a sequestering agent to improve their stability in air. EDTA tetrasodium salt is predominatly used in agriculture, water treatment, pulp and paper industries and also used in the manufacture of cleaners and detergents.
In Cleaning products EDTA is employed to remove hard water scale, soap film, and inorganic scales. It is commonly used in a wide variety of cleaning products and formulations, including hard surface cleaners, laundry detergents, bacteridal cleaners, vehicle washes etc.
EDTA is used in soaps ,many hair products, creams and lotions. In the textile industry, EDTA tetrasodium is emploted tp prevent metal ion impurities from changing colours of dyed products. For chlorine-free bleaching it inhibits the ability of metal ions, especially Mn2 , from catalysing the Hydrogen Peroxide.
In the manufacturing of paper to maximize bleaching efficiency during pulping, prevent brightness reversion, and protect bleach potency. In Scale removal and prevention - to clean calcium and other types of scale from boilers, evaporators, heat exchangers, filter cloths, and glass-lined kettles.
