Is disodium EDTA a chelating agent?
Edetate disodium (EDTA) is a chelating agent that is utilized for its metal-binding properties. It is best known as a treatment for calcific band keratopathy and has been used to neutralize corneal injuries due to calcium hydroxide, also known more commonly as lime burns.
How does EDTA work as a chelate?
EDTA is a versatile chelating agent. It can form four or six bonds with a metal ion, and it forms chelates with both transition-metal ions and main-group ions. The EDTA binds to them, sequestering them and preventing their interference.
Is disodium EDTA bad for you?
Calcium disodium EDTA is found in food, cosmetic and industrial products and used to treat metal toxicity. The ADI is 1.1 mg per pound (2.5 mg per kg) of body weight per day — much higher than what is typically consumed. At these levels, it’s considered safe without serious side effects.
What is EDTA used for?

What is EDTA used for in soap?
EDTA is widely used in colour cosmetics, soaps, shampoos and toiletries to prevent changes in colour, texture and fragrance. EDTA is a chelating agent formed of four carboxylic acid groups attached to two nitrogen atoms, which means that EDTA latches onto minerals and keeps them in place.
How is EDTA made?
EDTA is a chemical created from the combination of formaldehyde , sodium cyanide, and ethylene diamine. This chemical is added to many sodas, processed foods including sandwich spreads, salad dressings, sauces and numerous canned or pickled foods.
What is ethylenediaminetetraacetic acid?
EDTA, or ethylenediaminetetraacetic acid, is a popular chelating agent that’s used in food, as a medication in chelation therapy and in many household products. A chelating agent is a (usually organic) molecule that can form many bonds to a single metal ion.
