Application of tetrasodium ethylenediaminetetraacetic acid dihydrate
tetrasodium ethylenediaminetraacetic acid dihydrate has important applications in many fields.

In industrial production, it is an excellent chelating agent. It can closely combine with metal ions to form a stable complex. In the electroplating industry, it can effectively control the concentration of metal ions in the plating solution, ensure uniform and dense coating, and improve the quality and anti-corrosion performance of the coating. In the printing and dyeing industry, it can chelate metal ions in water to prevent them from reacting with dyes, avoid uneven dyeing, and help dye brightly colored and uniform fabrics.

In the field of water treatment, tetrasodium ethylenediaminetraacetic acid dihydrate has a significant effect. It can remove calcium, magnesium, iron and other metal ions in water, prevent the formation of scale, and reduce the hardness of water. For industrial circulating water systems, it can effectively inhibit the accumulation of scale in pipes and equipment, ensure the smooth operation of the system, and prolong the service life of the equipment. In drinking water treatment, it can also remove harmful metal ions in water, improve water quality, and ensure the safety of drinking water for the public.

It is also indispensable in the manufacture of daily chemical products. In detergent formulations, it can chelate metal ions in water, enhance the detergent's decontamination ability, and make clothes cleaner after washing. In skin care products, it can stabilize the metal ions in the formula, prevent their catalytic oxidation reaction, prolong the shelf life of the product, and ensure the safety and stability of product use.

In the food industry, tetrasodium ethylenediaminetetraacetate dihydrate can be used as a food additive. In canned food, it can chelate metal ions, inhibit the oxidation catalysis of metal ions on food, delay food deterioration, and prolong shelf life. In beverage production, it can prevent precipitation and discoloration caused by metal ions, and maintain the clarity and color of beverages.
