01 · Identification
What Octanoic Acid is
Octanoic Acid is solidifies to leafy crystals when cold with a faint, fruity-acid odor. It boils at 239 °C, melts at 16.5 °C, is miscible with water.
Under the GHS it carries the signal word Danger.

03 · GHS classification
Octanoic Acid hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Octanoic Acid pictograms and signal word
Octanoic Acid hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Skin corrosion/irritation GHS chapter 3.2 | Category 1A or 1B or 1C | H314 | GHS05 |
| Hazardous to the aquatic environment - chronic GHS chapter 4.1 | Category 3 | H412 | — |
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.
Octanoic Acid hazard statements (H-codes)
| Code | Hazard statement |
|---|---|
| H314 | Causes severe skin burns and eye damage. |
| H412 | Harmful to aquatic life with long lasting effects. |
This page lists only the codes assigned to Octanoic Acid. The full reference lives on the hazard statements hub, the precautionary statements hub and the GHS pictograms hub.
Safety Data Sheet
Getting an SDS for Octanoic 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 Octanoic 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
Octanoic Acid precautionary statements
CLP Annex VI assigns 7 precautionary statements to Octanoic 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.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
Octanoic Acid name in 22 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.

22 of the 23 language editions carry this entry; it is absent from Croatian. That is a property of the regulation, not a gap in this table — editions do occasionally differ in which entries they print. 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.

What does a Octanoic Acid label have to show?
Under CLP Annex VI the label for Octanoic Acid carries the pictogram Corrosion and the signal word is Danger.
Is Octanoic Acid flammable?
CLP Annex VI assigns Octanoic 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 130 °C (266 °F), open cup (HSDB).
Is Octanoic Acid a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Octanoic 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 boiling point of Octanoic Acid?
The boiling point reported for Octanoic Acid is 239 °C (462.2 °F) (HSDB).
What is the melting point of Octanoic Acid?
The melting point reported for Octanoic Acid is 16.5 °C (61.7 °F) (HSDB).
How should Octanoic Acid be stored?
