Safety Data Sheet

Getting an SDS for Propargite

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 Propargite 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

Propargite precautionary statements

CLP Annex VI assigns 17 precautionary statements to Propargite. 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

Propargite 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.

Propargite health hazards and exposure limits

Propargite hazard summary

Outbreaks of irritant contact dermatitis in farmworkers have been reported. [Kanerva, p. 787] Slowly reacts with water forming sulfur dioxide and alcohols; A skin, eye (may be severe), and mucous membrane irritant; [CAMEO] Reports of dermatitis and eye irritation in agricultural employees; [HSDB] Corrosive to rabbit skin and eyes; A skin sensitizer in guinea pigs; Classified as a probable human carcinogen based on fatal intestinal tumors in experimental animals; [Reference #1] A skin and severe eye irritant; Toxic by inhalation; [Aldrich MSDS]

Propargite carcinogenicity classification

Cancer Classification: Group B2 Probable Human Carcinogen

Source: Hazardous Substances Data Bank (HSDB)

Propargite is classified as a B2 chemical carcinogen based on the appearance of intestinal tumors in test animals. The cancer concern was based on a 2-year cancer bioassay conducted on Sprague Dawley ("SD") rats. In that study, propargite caused fatal tumors of the intestine in both male and female rats. In other studies on mice and Wistar rats, propargite did not exhibit carcinogenicity or mutagenicity.

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.

09 · Handling and storage

Propargite storage and handling

Propargite reactivity

PROPARGITE is a sulfite ester. As an ester, it will hydrolyze to form sulfur dioxide and alcohols; reaction is more rapid under basic conditions. It may react exothermically with acids to generate alcohols. Heat will be generated by interaction with basic or caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides.
