Ethylenediaminetetra-acetic acid (EDTA) is used in several industrial applications attributing to its high ability to bind to most of metal cations. EDTA is produced as several salts, e.g. ethylenediaminetetra-acetic acid disodium salt (EDTAS).
EDTA and its salts are used as chelating agents in cosmetic formulations. EDTAS is a preservative, sequestrant, and stabilizer in foods. EDTA is added to ascorbic acid-disodium benzoate containing soft drinks to mitigate the formation of benzene. EDTA and its salts are used as a component in the production of food-contact paper and paperboard.

EDTA 2Na (Ethylenediaminetetraacetic Acid Disodium Salt ) has a wide range of applications in many fields. The following are its main areas of application:
1. Food additives: In the food industry, EDTA 2Na is used as a food additive to improve the stability and shelf life of food. It can form stable complexes with metal ions (e.g. iron, calcium, magnesium, etc.) in food, thus preventing oxidative deterioration caused by metal ions. According to China's food safety standard (GB 2760-2014), EDTA 2Na can be used in foods such as jams, vegetable purees or sauces, preserved fruits, pickled vegetables, canned vegetables, canned nuts and seeds, canned miscellaneous grains, as well as compound seasonings and beverages, etc., with a clear maximum usage limit.
2. Cosmetic industry: EDTA 2Na is used as a stabiliser in cosmetics to help maintain the quality and stability of cosmetics. It can complex the metal ions in cosmetics to improve their stability and preservative properties. It also acts as a humectant and antioxidant, providing long-lasting moisturising and antioxidant protection for the skin.
3. Pharmaceutical industry: EDTA 2Na is also used in the pharmaceutical industry, such as in the treatment of liver and kidney diseases, as well as in the treatment of lead poisoning and heavy metal poisoning. It is also used as a complexing agent in the preparation of drugs and drug intermediates to ensure the purity and quality of the drugs.
4. Industrial production: EDTA 2Na has various applications in industrial production, such as as the textile industry as a dye orientating agent, as well as for paper, leather, metallurgy and other industrial fields. In addition, EDTA 2Na is used as an active agent in the reduction initiation system for the polymerisation of styrene-butadiene rubber, mainly for complexing ferrous ions and controlling the speed of the polymerisation reaction.
Overall, EDTA 2Na has important applications in many fields due to its strong complexing ability with metal ions.
Ethylenediaminetetraacetic acid disodium salt is widely used in textile industry. Usually applied to dissolve limescale. It is applied in textile industry, pulp and paper industry and also in chelation therapy. In cosmetics, it acts as a sequestering agent. It acts as a corrosion inhibitor to carbon steel in the industries. It also acts as a food additive.
Ethylenediaminetetraacetic acid disodium salt dihydrate has been in seed germination trials of plant species and in protein extraction from Moss, Physcomitrella paten. It has also been used in lysis and vacuole buffer for the isolation of vacuoles from Petunia petals. Chelator of divalent cations. Inhibits enzymes, such as metalloproteases, that require divalent cations for activity.
Ethylenediaminetetraacetic acid disodium salt dehydrate is designated as Molecular Biology grade and is suitable for molecular biology applications. It has been analyzed for the presence of nucleases and protease.
