A white solid crystalline acid, it acts as a strong complexing and chelating agent that reacts with many metallic ions to form soluble chelates.


The sodium salt of is used as an antidote for metal poisoning and as an anticoagulant, and ingredient in a variety of industrial reagents as well as in analysis for retaining alkaline earths and heavy metals in solutions and for dissolving scales.

As a cheating agent, EDTA Tetrasodium is used to sequester and decrease the reactivity of metal ions that may be present in a product OR a molecule which complexes metal ions in aqueous environments.


it is found in moisturizers, skin care and cleansing products, personal cleanliness products, bath soaps, shampoos and conditioners, hair dyes, hair bleaches, etc. In addition, Tetrasodium EDTA works synergistically with your preservative to improve preservative efficacy.




is prepared from the reaction of Sodium Hydroxide with EDTA

• EDTA TetraSodium is used predominantly in agriculture, water treatment, pulp and paper industries and in the manufacture of cleaners and detergents.


• Used in Metalworking industries for surface preparation, metal cleaning, metal plating, and in metalworking fluids.


• In Cleaning Products, it is used for removing hard water scale, soap film, and inorganic scales. EDTA TetraSodium is commonly used in a wide variety of cleaning products and formulations, including hard surface cleaners, laundry detergents, bacterial cleaners, vehicle washes etc.


• In Soaps, it is used to counteract the defoaming action of hardness ions, reducing soap scum and improving lather.


• In Photography, it is used as bleach in photographic film processing.


• In Paper Industry, it is used in the manufacturing of paper to maximize bleaching efficiency during pulping, prevent brightness reversion, and protect bleach potency.


• Used in Scale removal and prevention – to clean calcium and other types of scale from boilers, evaporators, heat exchangers, filter cloths, and glass-lined kettles.


• In Water Treatment, it is used to control water hardness and scale-forming calcium and magnesium ions and to prevent scale formation.


• Used for dissolving and removing Sulphate Deposits from lead acid batteries, it is especially useful in case of Old Batteries extending their life.






• it is irritating to skin

• If eye contact is made with it, there is risk of serious damage to eyes.

• it may cause sensitization by skin contact.




• While handling or using it, avoid contact with skin.
