Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
2,4,6-Trimethylbenzoyl… pictograms and signal word
2,4,6-Trimethylbenzoyl… 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.

Safety Data Sheet
Getting an SDS for 2,4,6-Trimethylbenzoyl…
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 2,4,6-Trimethylbenzoyl… 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
2,4,6-Trimethylbenzoyl… precautionary statements
CLP Annex VI assigns 5 precautionary statements to 2,4,6-Trimethylbenzoyl…. 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
2,4,6-Trimethylbenzoyl… 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.
