Safety Data Sheet

Getting an SDS for Deltamethrin

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 Deltamethrin 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

Deltamethrin precautionary statements

CLP Annex VI assigns 10 precautionary statements to Deltamethrin. 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.

Disposal

05 · Names in the regulation

Deltamethrin 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.

Deltamethrin carcinogenicity classification

IARC classification Group 3 — Not classifiable as to its carcinogenicity to humans
IARC monographs Volume 53: (1991) Occupational Exposures in Insecticide Application, and Some Pesticides

Cancer Classification: Not Likely to be Carcinogenic to Humans

Source: Hazardous Substances Data Bank (HSDB)

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

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.

11 · Questions

Deltamethrin — frequently asked questions

What is the CAS number of Deltamethrin?

The CAS number of Deltamethrin is 52918-63-5. Its EC number is 258-256-6.

What is the chemical formula of Deltamethrin?

The molecular formula of Deltamethrin is C22H19Br2NO3 and its molecular weight is 505.2 g/mol.

What does a Deltamethrin label have to show?

Under CLP Annex VI the label for Deltamethrin carries the pictograms Skull and crossbones and Environment and the signal word is Danger.

Is Deltamethrin flammable?

CLP Annex VI assigns Deltamethrin 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 Deltamethrin a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Deltamethrin. 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. IARC places it in Group 3: not classifiable as to its carcinogenicity to humans.

What is the melting point of Deltamethrin?

The melting point reported for Deltamethrin is 90 °C (194 °F) (HSDB).

How should Deltamethrin be stored?

Pyrethrins with piperonyl butoxide topical preparations should be stored in well-closed containers at a temperature less than 40 °C, preferably between 15-30 °C. /Pyrethrins/ (Hazardous Substances Data Bank (HSDB))
