Applications

1. Metal Ion Sequestrant For Water Treatment: In water treatment and industrial process water it locks up iron, manganese, copper and hardness ions, controlling scale and deposit formation and keeping metal ions from interfering with downstream chemistry.

2. Metal Ion Control In Textile And Paper: In textile and paper processing it binds trace metals that would otherwise catalyse oxidation or discolouration, protecting whiteness and shade consistency in bleached and dyed goods.

3. Chelated Micronutrients For Agriculture: It is a component of manganese and zinc fertiliser formulations, and iron chelated with DTPA is supplied as a micronutrient iron source, for example in aquatic plant fertilisers at about 10 to 11 percent iron.

4. Chelating Agent For Cosmetics And Personal Care: In cosmetic and personal care formulations it binds trace metal ions that would otherwise catalyse the breakdown of oils, actives and fragrance, helping stabilise colour, odour and shelf life.

5. Chelant For Cleaning And Analytical Work: In cleaning and industrial formulations it deactivates hardness and transition metal ions that cut cleaning performance, and in the laboratory it is used as an analytical reagent for metal ion control.
