Safety Data Sheet

Getting an SDS for Piperonyl Butoxide

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 Piperonyl Butoxide 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

Piperonyl Butoxide precautionary statements

CLP Annex VI assigns 9 precautionary statements to Piperonyl Butoxide. 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

Piperonyl Butoxide 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.

Piperonyl Butoxide carcinogenicity classification

IARC classification Group 3 — Not classifiable as to its carcinogenicity to humans
IARC monographs Volume 30: (1983) Miscellaneous Pesticides

Studied by the US National Toxicology Program: TR-120: Bioassay of Piperonyl Butoxide for Possible Carcinogenicity (CASRN 51-03-6) (1979 )

PBO is classified as a Group C-possible human carcinogen with no cancer quantification required for PBO risk assessments.

Source: Hazardous Substances Data Bank (HSDB)

No data are available in humans. Inadequate evidence of carcinogenicity in animals. OVERALL EVALUATION: Group 3: The agent is not classifiable as to its carcinogenicity 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.

11 · Questions

Piperonyl Butoxide — frequently asked questions

What is the CAS number of Piperonyl Butoxide?

The CAS number of Piperonyl Butoxide is 51-03-6. Its EC number is 200-076-7.

What is the chemical formula of Piperonyl Butoxide?

The molecular formula of Piperonyl Butoxide is C19H30O5 and its molecular weight is 338.4 g/mol.

What does a Piperonyl Butoxide label have to show?

Under CLP Annex VI the label for Piperonyl Butoxide carries the pictograms Exclamation mark and Environment and the signal word is Warning.

Is Piperonyl Butoxide flammable?

CLP Annex VI assigns Piperonyl Butoxide 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. The flash point reported for it is 171.11 °C (340 °F) (HSDB).

Is Piperonyl Butoxide a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Piperonyl Butoxide. 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 boiling point of Piperonyl Butoxide?

The boiling point reported for Piperonyl Butoxide is 180 °C (356 °F), at 1 mmHg (reduced pressure), Technical (HSDB).

How should Piperonyl Butoxide be stored?

Safe Storage of Pesticides. Always store pesticides in their original containers, complete with labels that list ingredients, directions for use, and first aid steps in case of accidental poisoning. Never store pesticides in cabinets with or near food, animal feed, or medical supplies. Do not store pesticides in places where flooding is possible or in places where they might spill or leak into wells, drains, ground water, or surface water. (Hazardous Substances Data Bank (HSDB))
