03 · GHS classification

Cyfluthrin hazard classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

Cyfluthrin hazard class and category

GHS hazard classes Cyfluthrin falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 1 or 2 H300 GHS06
Acute toxicity - inhalation GHS chapter 3.1 Category 1 or 2 H330 GHS06
Reproductive toxicity GHS chapter 3.7 Category Lactation H362
Specific target organ toxicity - single exposure GHS chapter 3.8 Category 1 H370 GHS08
Hazardous to the aquatic environment - acute GHS chapter 4.1 Category 1 H400 GHS09
Hazardous to the aquatic environment - chronic GHS chapter 4.1 Category 1 H410 GHS09

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 Cyfluthrin

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 Cyfluthrin 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

Cyfluthrin precautionary statements

CLP Annex VI assigns 12 precautionary statements to Cyfluthrin. 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.

05 · Names in the regulation

Cyfluthrin 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.

Cyfluthrin health hazards and exposure limits

Cyfluthrin hazard summary

A skin, eye, and mucous membrane irritant; In human experiments, the threshold for upper respiratory tract irritation was 0.1 mg/m3; Common symptoms after overexposure in the workplace are stinging sensations of the skin and mucous membranes that begin 1-2 hours after contact and last for 1-2 days; Such symptoms are thought to be due to local action on sensitive nerves; [HSDB] Toxic by inhalation and ingestion; [eChemPortal: ESIS] A skin and eye irritant; [MSDSonline]

Cyfluthrin carcinogenicity classification

Cancer Classification: Not Likely to be Carcinogenic to 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.

Cyfluthrin storage conditions

PESTICIDE STORAGE: Store in a cool, dry place and away from open flame and extreme heat. Store in such a manner as to prevent cross contamination with other pesticides, fertilizers, food, and feed. Store in original container and out of the reach of children, preferably in locked storage area. Handle and open container in a manner as to prevent spillage. If container is leaking, invert container to prevent leakage. If the container is leaking or material spilled for any reason or cause, carefully dam up spilled material to prevent runoff. Refer to Precautionary Statements on /product/ label for hazards associated with the handling of this material. Do not walk through spilled material. ... /Baythroid XL/

11 · Questions

Cyfluthrin — frequently asked questions

What is the CAS number of Cyfluthrin?

The CAS number of Cyfluthrin is 68359-37-5. Its EC number is 269-855-7.

What is the chemical formula of Cyfluthrin?

The molecular formula of Cyfluthrin is C22H18Cl2FNO3 and its molecular weight is 434.3 g/mol.

What does a Cyfluthrin label have to show?

Under CLP Annex VI the label for Cyfluthrin carries the pictograms Skull and crossbones, Health hazard and Environment and the signal word is Danger.

Is Cyfluthrin flammable?

CLP Annex VI assigns Cyfluthrin 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 Cyfluthrin a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Cyfluthrin. 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 Cyfluthrin?

The melting point reported for Cyfluthrin is 60 °C (140 °F) (HSDB).

How should Cyfluthrin be stored?

PESTICIDE STORAGE: Store in a cool, dry place and away from open flame and extreme heat. Store in such a manner as to prevent cross contamination with other pesticides, fertilizers, food, and feed. Store in original container and out of the reach of children, preferably in locked storage area. Handle and open container in a manner as to prevent spillage.
