Safety Data Sheet
Getting an SDS for Ethoxyquin
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 Ethoxyquin 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
Ethoxyquin precautionary statements
CLP Annex VI assigns 4 precautionary statements to Ethoxyquin. 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
Ethoxyquin 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.

What does a Ethoxyquin label have to show?
Under CLP Annex VI the label for Ethoxyquin carries the pictogram Exclamation mark and the signal word is Warning.
Is Ethoxyquin flammable?
CLP Annex VI assigns Ethoxyquin 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 107.22 °C (225 °F) (CAMEO).
Is Ethoxyquin a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Ethoxyquin. 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.

The boiling point reported for Ethoxyquin is 124 °C (255.2 °F), range, midpoint shown, at 2 mmHg (reduced pressure) (HSDB).
What is the melting point of Ethoxyquin?
