Safety Data Sheet

Getting an SDS for 5,5-dimethyl-perhydro-pyri…

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 5,5-dimethyl-perhydro… 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

5,5-dimethyl-perhydro-pyrimidi… precautionary statements

CLP Annex VI assigns 15 precautionary statements to 5,5-dimethyl-perhydro-pyri…. 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

5,5-dimethyl-perhydro-pyrimidi… 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.

Cancer Classification: Group C Possible Human Carcinogen

The /EPA Pesticides/ Cancer Peer Review Committee determined that hydramethylnon should be classified as a Group C carcinogen, a possible human carcinogen, and recommended that, for the purpose of risk characterization, the Reference Dose approach should be used for quantification of human risk.

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 does a 5,5-dimethyl-perhydro-pyrimidi… label have to show?

Under CLP Annex VI the label for 5,5-dimethyl-perhydro-pyrimidi… carries the pictograms Health hazard, Exclamation mark and Environment and the signal word is Danger.

Is 5,5-dimethyl-perhydro-pyrimidi… flammable?

CLP Annex VI assigns 5,5-dimethyl-perhydro-pyrimidi… 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 104.44 °C (220 °F), above this value (HSDB).

Is 5,5-dimethyl-perhydro-pyrimidi… a carcinogen?
