Safety Data Sheet
Getting an SDS for 2-(propyloxy)ethanol
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 2-(propyloxy)ethanol 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
2-(propyloxy)ethanol precautionary statements
CLP Annex VI assigns 9 precautionary statements to 2-(propyloxy)ethanol. 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
2-(propyloxy)ethanol 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.

2-(propyloxy)ethanol reactivity
Ethers, such as ETHYLENE GLYCOL PROPYL ETHER can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.

Is 2-(propyloxy)ethanol a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for 2-(propyloxy)ethanol. 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 boiling point of 2-(propyloxy)ethanol?
The boiling point reported for 2-(propyloxy)ethanol is 149.44 °C (301 °F), at 760 mmHg (CAMEO).
What is the melting point of 2-(propyloxy)ethanol?
The melting point reported for 2-(propyloxy)ethanol is -90 °C (-130 °F) (ICSC).
