Safety Data Sheet
Getting an SDS for Edetic acid
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Edetic acid issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
04 · Precautionary statements
Edetic acid precautionary statements
CLP Annex VI assigns 6 precautionary statements to Edetic acid. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation
Edetic acid name in 23 EU languages
CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

Edetic acid storage and handling
Edetic acid safe storage
Separated from strong oxidants, metals and food and feedstuffs.

Edetic acid storage conditions
Chelating agents, by their very nature, tend to be corrosive to metals such as copper, zinc, and iron. The alkaline salts corrode aluminum severely, and contact with these salts should be avoided. Stainless steel and most polymers or coatings that are able to withstand dilute alkali are acceptable as construction materials. Solid chelating agents should be stored in a cool, dry place to avoid caking. /Chelating agents/

10 · Questions
Edetic acid — frequently asked questions
What is the CAS number of Edetic acid?
The CAS number of Edetic acid is 60-00-4. Its EC number is 200-449-4.
What is the chemical formula of Edetic acid?
The molecular formula of Edetic acid is C10H16N2O8 and its molecular weight is 292.24 g/mol.
What does a Edetic acid label have to show?
Under CLP Annex VI the label for Edetic acid carries the pictogram Exclamation mark and the signal word is Warning.
Is Edetic acid flammable?
CLP Annex VI assigns Edetic acid no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it. The flash point reported for it is 100 °C (212 °F), above this value (HSDB).
Is Edetic acid a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Edetic acid. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.
What is the melting point of Edetic acid?
The melting point reported for Edetic acid is 245 °C (473 °F) (HSDB).
How should Edetic acid be stored?
Chelating agents, by their very nature, tend to be corrosive to metals such as copper, zinc, and iron. The alkaline salts corrode aluminum severely, and contact with these salts should be avoided. Stainless steel and most polymers or coatings that are able to withstand dilute alkali are acceptable as construction materials. Solid chelating agents should be stored in a cool, dry place to avoid caking. /Chelating agents/ (Hazardous Substances Data Bank (HSDB))
