The Complete Guide to EDTA Manufacturers in India and How They are Revolutionizing the Industry


What is EDTA?

EDTA or ethylenediaminetetraacetic acid is a weak acid used as a chelating agent. Ethylenediaminetetraacetic acid (EDTA) contains an amino carboxylic group with the formula C10H16N2O8.

The chelating agent EDTA is a compound of massive use worldwide with household and industrial applications, being one of the anthropogenic compounds with the ability to sequester various polyvalent cations, used to minimize metal contaminants and facilitate enzymatic reactions that could be inhibited by heavy metal traces. EDTA is the most widely used chelating agent for the removal of toxic heavy metal ions in wastewater treatment.


What is the Process of Manufacturing EDTA?

EDTA is prepared from the compound Ethylenediamine and Monochloroacetic acid. EDTA grabs metallic cations such as lead or calcium from the process and forms a stable compound that is then excreted from the system. If the bond is weak, other chemicals can break this bond to form their own compounds. EDTA is the most widely used chelating agent for the removal of toxic heavy metal ions in wastewater treatment.

EDTA can react with metallic cations, creating a stable rigid compound that can be easily excreted from the application system. Inorganic Contaminants may react with metallic ions, forming their own compounds due to their ability to form a strong covalent bond with those metal compounds.


EDTA Application Areas

Wastewater treatment: EDTA is the most widely used chelating agent for the removal of removing toxic heavy metal ions in wastewater treatment.

Textile industry: Prevents metal ion impurities from modifying colours of dyed products.

Pulp & paper industry: It inhibits the ability of metal ions, especially Manganese from catalysing the disproportionation of hydrogen peroxide in chlorine-free bleaching.

Laundry: Reduces water hardness by dissolving scales of Ca2+, Mg2+, and cations, which are then less likely to interfere with soaps and detergents

‘Scrubbing’: Removes hydrogen sulphide from gas streams. This conversion is achieved by oxidizing the hydrogen sulphide to elemental sulphur, which is non-volatile.

Laboratory: Widely used for scavenging metal ions.

Cosmetics: Used in shampoos, cleaners, and other personal care products as a sequestering agent


EDTA Manufacturers in India





Chemtex Speciality Limited is a pioneering speciality chemicals manufacturer and is one of India’s leading EDTA manufacturers, available in Tetrasodium salt (EDTA 4Na), Disodium EDTA (EDTA 2Na), Trisodium EDTA (EDTA 3Na) and Pure Acid form.

Disodium EDTA (EDTA 2Na) – Disodium salt of EDTA is used as sequestering / chelating agent, that helps in cleaning and descaling from metal surfaces. Also, it finds extensive usage in the removal of iron oxide/hydroxide and calcium carbonate, other organic substances and microbial slimes.

Trisodium EDTA (EDTA 3Na) – It is used as a disinfectant, colour retention agent, anticoagulant for blood collection, preservative, antioxidant, chelating agent in personal care products and flavouring agent for foods. It is used to minimize metal ion contaminants, and to facilitate enzymatic reactions that could be inhibited by heavy metal traces.

Tetrasodium EDTA (EDTA 4Na) – Tetrasodium EDTA is also used as a chelating agent, with the ability to sequester various polyvalent cations, that bind calcium, magnesium and other metal ions, minimizing metal ion contamination and facilitating enzymatic reactions that could be inhibited by heavy metal traces. EDTA Tetrasodium Salt also works as a slime dispersant and is even effective in reducing scale deposits and water hardness.
