1. The Centres for Disease Control and Prevention (CDC), which investigated Abubakar‘s death, has said he was given a synthetic amino acid called Disodium EDTA instead of Calcium Disodium EDTA.

2. The form of EDTA used in the trial is supplied by AkzoNobel, a Dutch company, Lamas said.

3. Chelation (pronounced kee–LAY–shun) involves intravenous doses of a drug, in this case disodium EDTA, that proponents claim will bind to calcium built up in artery walls and help flush it from the body.

4. Your bubble bath is likely to contain potentially irritating detergents like sodium laureth sulphate and cocami–dopropyl betaine (the latter is also a penetration enhancer, allowing other chemicals to be more easily absorbed); preservatives such as tetrasodium EDTA, a potential irritant; and methylchloroisothiazolinone (both potential mutagens — substances that speed up gene mutation). If it contains cocamide EDTA (or similar compounds ending with DEA, TEA or MEA) along with formaldehyde–forming substances such as bronopol, DMDM hydantoin, diazo–lidinyl urea, imidazolidinyl urea and quaternium–15, it is likely to contain cancer–causing nitrosamines.
