EDTA is sometimes prescribed by doctors to clean toxic metals, such as lead, from the blood. Doctors have used the molecule for decades to treat heavy metal poisoning. In those cases it is given through an IV. EDTA is also an ingredient in some prescription cancer-fighting medicines.

What does EDTA do in a reaction?
The EDTA molecule seizes the metal ion as if with a claw, and keeps it from reacting normally with other substances. Chelating agents play an important roll in many products, such as food, soda, shampoo, and cleaners. All of these products contain unwanted metal ions which affect color, odor, and appearance.
Is EDTA harmful to humans?
EDTA can cause abdominal cramps, nausea, vomiting, diarrhea, headache, low blood pressure, skin problems, and fever. It is UNSAFE to use more than 3 grams of EDTA per day, or to take it longer than 5 to 7 days. Too much can cause kidney damage, dangerously low calcium levels, and death.
Is EDTA a salt?
An organic sodium salt that is the anhydrous form of the disodium salt of ethylenediaminetetraacetic acid (EDTA).
Is EDTA an acid or base?
EDTA is a Weak Acid. EDTA, ethylenediaminetetraacetic acid, has four groups of carboxyls and two groups of amines that can serve as donors of electron pairs, or Lewis bases.
What is EDTA in titration?
EDTA Complexometric Titration EDTA called as ethylenediaminetetraacetic acid is a complexometric indicator consisting of 2 amino groups and four carboxyl groups called as Lewis bases. Edta is a hexadentate ligand because of its competence to denote six pair of lonely electrons due to the formation of covalent bonds.
Why is EDTA used in buffers?
EDTA (ethylenediaminetetraacetic acid) is a chelating agent that binds divalent metal ions such as calcium and magnesium. EDTA can be used to prevent degradation of DNA and RNA and to inactivate nucleases that require metal ions. EDTA can also be used to inactivate metal ion-requiring enzymes.
Can EDTA cause organ damage?
In addition, some people may have an allergic reaction to EDTA. Other serious side effects that have been reported include low blood sugar, diminished calcium levels, headache, nausea, dangerously low blood pressure, kidney failure, organ damage, irregular heartbeat, seizures, or even death.
Is EDTA natural?
Is EDTA natural? As mentioned before, disodium EDTA is a synthetic ingredient and not naturally occurring.
What foods have EDTA in them?
- Salad dressings, sauces and spreads.
- Mayonnaise.
- Pickled vegetables, such as cabbage and cucumbers.
- Canned beans and legumes.
- Canned carbonated soft drinks.
- Distilled alcoholic beverages.
- Canned crab, clam and shrimp.
What is another name for EDTA?
It is used in medicine to prevent blood samples from clotting and to remove calcium and lead from the body. It is also used to keep bacteria from forming a biofilm (thin layer stuck to a surface). It is a type of chelating agent. Also called edetic acid and etheylenediaminetetraacetic acid.
Does EDTA dissolve in water?
EDTA salts are more soluble in water as the pH increases: the more EDTA there is in the salt form, the higher the pH of a water solution, and therefore, the higher the room temperature solubility. This can be achieved by a gradual addition of concentrated sodium hydroxide solution to the EDTA solution.
What is the pH of EDTA?
EDTA (0.5 M), pH 8.0.
What is EDTA made of?
Today, EDTA is mainly synthesised from ethylenediamine (1,2-diaminoethane), formaldehyde, and sodium cyanide.
Is EDTA a weak or strong acid?
EDTA is a Weak Acid.
What metals can EDTA bind to?
EDTA is an amino acid widely used to sequester di- and trivalent metal ions (Ca2+ and Mg2+ for example). EDTA binds to metals via four carboxylate and two amine groups. EDTA forms especially strong complexes with Mn(II), Cu(II), Fe(III), Pb (II) and Co(III).
Why is EDTA used to determine the hardness of water?
The hardness of water is estimated by simple titration of ethylene diamine tetraacetate (EDTA) solution. EDTA forms stable complexes with the metal ions present in the hard water since stability constants of calcium and magnesium complexes of EDTA are different, even the selective estimation of these ions is possible.
Does EDTA buffer pH?
EDTA Buffer pH 8.0 | Medicago.
How do you remove EDTA from a solution?
For a number of subsequent applications EDTA needs to be exhaustively removed. Most purification methods rely in extensive dialysis and/or gel filtration in order to exchange or remove protein buffer components, including metal chelators.
Why pH is controlled in EDTA titrations?
‘ pH control is very crucial for complexometric titrations because all reactions of EDTA and metal ions rely on pH and for the complete dissociation reaction to occur, the solution must be basic in nature with a pH range of 8 to 10.
How long does EDTA stay in the body?
Lead poisoning and heavy metal toxicity Injected intravenously and once in the bloodstream, EDTA traps lead and other metals, forming a compound that the body can eliminate in the urine. The process generally takes 1 to 3 hours.
Is EDTA carcinogenic?
The typical concentration of use of EDTA is less than 2%, with the other salts in current use at even lower concentrations. The lowest dose reported to cause a toxic effect in animals was 750 mg/kg/day. These chelating agents are cytotoxic and weakly genotoxic, but not carcinogenic.
Does EDTA cause hair loss?
Does EDTA cause hair loss? EDTA is not one of the ingredients in shampoo that causes hair loss.
Is EDTA toxic to cells?
Results: When solely applied, EDTA does not exhibit any cell toxicity nor does it add any toxicity to oxaliplatin.
Is EDTA harmful to skin?
Facts: EDTA is safe for use in cosmetics, and for decades the data is well-reported. At the concentration level as it is used in our products, EDTA is a well-tolerated ingredient and allergic cases are very rare.
