- Chelating agents are used to solubilize hard water salts so that they stay in solution.
- Chelating agents are used in alkaline cleaners.
- Chelating agents do not decompose or lose their effectiveness at high temperatures.
- A major disadvantage of chelating agents is that they impair the ability of other chemicals to remove emulsified oil and dissolved metals from the solution. This can create a waste disposal problem.
- Chelating agents are produced in both powder and liquid form.
- The most common chelating agents are ethylene diamine tetracetic acid (EDTA) and nitrilo triacetate (NTA).
