03 · GHS classification
C.I. Disperse Yellow 3 hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
C.I. Disperse Yellow 3 pictograms and signal word
C.I. Disperse Yellow 3 hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Skin sensitisation GHS chapter 3.4 | Category 1 or 1A or 1B | H317 | GHS07 |
| Carcinogenicity GHS chapter 3.6 | Category 2 | H351 | GHS08 |
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.
C.I. Disperse Yellow 3 hazard statements (H-codes)
| Code | Hazard statement |
|---|---|
| H351 | Suspected of causing cancer <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
| H317 | May cause an allergic skin reaction. |

Safety Data Sheet
Getting an SDS for C.I. Disperse Yellow 3
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 C.I. Disperse Yellow 3 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
C.I. Disperse Yellow 3 precautionary statements
CLP Annex VI assigns 7 precautionary statements to C.I. Disperse Yellow 3. 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
C.I. Disperse Yellow 3 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.

C.I. Disperse Yellow 3 carcinogenicity classification
Under the conditions of this bioassay, C.I. Disperse Yellow 3 was considered to be carcinogenic for male F344 rats, causing an increased incidence of neoplastic nodules of the liver; this dye was not carcinogenic for female F344 rats. In addition, the stomach tumors found in the male rats may have been induced by the administration of the test chemical. C.I. Disperse Yellow 3 was carcinogenic for female B6C3F1 mice, as evidenced by the increased incidence of hepatocellular adenomas; C.I. Disperse Yellow 3 was not carcinogenic for male B6C3F1 mice. Also, the increased incidence of malignant lymphoma in female mice may have been associated with the administration of C.I. Disperse Yellow 3.

Evaluation: There is limited evidence for the carcinogenicity of Disperse Yellow 3 in experimental animals. No data were available from studies in humans on the carcinogenicity of Disperse Yellow 3. Overall evaluation: Disperse Yellow 3 is not classifiable as to its carcinogenicity to humans (Group 3).

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

09 · Handling and storage
C.I. Disperse Yellow 3 storage and handling
C.I. Disperse Yellow 3 reactivity
C.I. DISPERSE YELLOW 3 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. This chemical is incompatible with strong oxidizing agents and strong acids (NTP, 1992).
