Safety Data Sheet
Getting an SDS for Hexan-1-ol
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 Hexan-1-ol 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
Hexan-1-ol precautionary statements
CLP Annex VI assigns 4 precautionary statements to Hexan-1-ol. 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
Hexan-1-ol 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.

Hexan-1-ol health hazards and exposure limits
Hexan-1-ol hazard summary
May cause first degree burns after short exposure and second degree burns after longer contact; [CHRIS] Undiluted 1-Hexanol is a mild irritant. Application of 0.2 ml to 27-28 volunteers caused no noticeable skin effects. 1-Hexanol caused corneal burns from which patients recovered within 48 hours. Ingestion can lead to symptoms of alcohol intoxication. [CHEMINFO]

Hexan-1-ol reactivity
HEXANOLS are alcohols. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
