Geraniol hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Geraniol pictograms and signal word
Geraniol hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Skin sensitisation GHS chapter 3.4 | Category 1 or 1A or 1B | H317 | GHS07 |
Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.
Geraniol hazard statements (H-codes)
| Code | Hazard statement |

Safety Data Sheet
Getting an SDS for Geraniol
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 Geraniol 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
Geraniol precautionary statements
CLP Annex VI assigns 5 precautionary statements to Geraniol. 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
Geraniol 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.

Geraniol incompatible materials
Incompatible materials Strong oxidizing agents, acid chlorides, acid anhydrides
Source: Hazardous Substances Data Bank (HSDB)
Geraniol reactivity
An unsaturated aliphatic hydrocarbon and an alcohol. 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.

What does a Geraniol label have to show?
Under CLP Annex VI the label for Geraniol carries the pictogram Exclamation mark and the signal word is Warning.
Is Geraniol flammable?
CLP Annex VI assigns Geraniol 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 108 °C (226.4 °F) (HSDB).
Is Geraniol a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Geraniol. 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 Geraniol?
The boiling point reported for Geraniol is 230 °C (446 °F) (HSDB).
What is the melting point of Geraniol?
The melting point reported for Geraniol is -15 °C (5 °F) (HSDB).
How should Geraniol be stored?
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Storage class (TRGS 510): Combustible liquids. (Hazardous Substances Data Bank (HSDB))
