Tetrasodium ethylenediaminetetraacetate, serving as the tetrasodium salt form of ethylenediaminetetraacetic acid (EDTA), is a potent chelating agent capable of forming stable, water-soluble complexes with various metal ions (such as calcium, magnesium, iron, and copper). At room temperature, Tetrasodium EDTA presents as a white crystalline powder; it is readily soluble in water but insoluble in alcohols and common organic solvents, and the pH of its 1% aqueous solution is approximately 11.8. Owing to its exceptional chelating properties and high solubility under alkaline conditions, it is widely utilized in fields such as industrial cleaning, textile printing and dyeing, water treatment, pharmaceuticals, and food processing.

In the field of industrial cleaning, Tetrasodium EDTA is the preferred raw material for formulating industrial descalers and heavy-duty cleaners, owing to its strong alkalinity and high chelating capacity; it effectively removes alkaline scale from boilers and heat exchangers.
In the daily chemical industry, it frequently serves as an additive in liquid detergents, chelating calcium and magnesium ions present in water to enhance the detergent’s cleaning efficacy; it also functions as a stabilizer and a preservative booster in cosmetic products.
In the textile dyeing and printing industry, it is utilized as an oxygen bleaching stabilizer to prevent the premature decomposition of hydrogen peroxide—catalyzed by heavy metal ions—during the bleaching process, thereby safeguarding both the whiteness and tensile strength of the fabric.
In the pharmaceutical sector—although the disodium form (EDTA-2Na) is more commonly employed for anticoagulation purposes (such as in blood collection tubes)—the tetrasodium form is frequently used to formulate alkaline cleaning agents or serves as an excipient in certain medications, primarily due to its high solubility.
In the food industry, Tetrasodium EDTA can be utilized as a food processing aid; its primary function is to chelate metal ions, thereby preventing food oxidation, spoilage, discoloration, or turbidity, and effectively extending product shelf life.
