Pyrithione Zinc hazard class and category

GHS hazard classes Pyrithione Zinc falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 3 H301 GHS06
Acute toxicity - inhalation GHS chapter 3.1 Category 1 or 2 H330 GHS06
Serious eye damage/eye irritation GHS chapter 3.3 Category 1 H318 GHS05
Specific target organ toxicity - repeated exposure GHS chapter 3.9 Category 1 H372 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 Pyrithione Zinc

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 Pyrithione Zinc 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

Pyrithione Zinc precautionary statements

CLP Annex VI assigns 14 precautionary statements to Pyrithione Zinc. 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

Pyrithione Zinc 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.

What does a Pyrithione Zinc label have to show?

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

Is Pyrithione Zinc flammable?

CLP Annex VI assigns Pyrithione Zinc 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 Pyrithione Zinc a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Pyrithione Zinc. 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.

The melting point reported for Pyrithione Zinc is 240 °C (464 °F), decomposes (HSDB).

How should Pyrithione Zinc 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.
