Safety Data Sheet
Getting an SDS for Pyridaben
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 Pyridaben 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
Pyridaben precautionary statements
CLP Annex VI assigns 10 precautionary statements to Pyridaben. 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
Pyridaben 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.

All 23 language editions of Annex VI carry this entry. 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.

Pyridaben health hazards and exposure limits
Pyridaben hazard summary
An eye irritant; No developmental toxicity below doses that were maternally toxic; NOAEL = 50 mg/kg/day for systemic toxicity in rats with decreased food intake and weight loss; [HSDB] Toxic by ingestion or inhalation; Very toxic to aquatic organisms; [European Commission]

Pyridaben carcinogenicity classification
Cancer Classification: Group E Evidence of Non-carcinogenicity for Humans
Source: Hazardous Substances Data Bank (HSDB)
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.

What is the CAS number of Pyridaben?
The CAS number of Pyridaben is 96489-71-3. Its EC number is 405-700-3.
What does a Pyridaben label have to show?
Under CLP Annex VI the label for Pyridaben carries the pictograms Skull and crossbones and Environment and the signal word is Danger.
Is Pyridaben flammable?
CLP Annex VI assigns Pyridaben 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.
Is Pyridaben a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Pyridaben. 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 melting point of Pyridaben?
The melting point reported for Pyridaben is 111.5 °C (232.7 °F), range, midpoint shown (HSDB).
How should Pyridaben be stored?
Store in a cool, dry place. Do not contaminate water, food, or feed with storage or disposal. /BASF Pyridaben Manf Use Prod/ (Hazardous Substances Data Bank (HSDB))
