Safety Data Sheet

Getting an SDS for (2R,6aS,12aS)-1,2,6,6a,12…

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 (2R,6aS,12aS)-1,2,6,6a… 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

(2R,6aS,12aS)-1,2,6,6a,12,12a… precautionary statements

CLP Annex VI assigns 16 precautionary statements to (2R,6aS,12aS)-1,2,6,6a,12…. 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.

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.

(2R,6aS,12aS)-1,2,6,6a,12,12a… hazard summary

Formulations for home use are classified as slightly toxic. The emulsified concentrate is classified as highly toxic. Only certified applicators can use rotenone on cranberries and for fish control. [EXTOXNET] Skin and respiratory irritation has been reported after occupational exposure. [EPA Pesticides] Poisoning by ingestion in humans may result in convulsions and coma. [ACGIH] Liver and kidney injury may occur after ingestion. [ICSC] Rotenone is used in an experimental animal model of Parkinson's syndrome, but the large doses used are not likely to be relevant to occupational exposure levels. [Reference #2] Decomposes within days when exposed to light and air; No evidence to support a causal relationship between rotenone and Parkinson's disease; In a fatal poisoning case, the estimated oral dose was 50 mg/kg, and the symptoms were coma and respiratory arrest within 8.5 hours of ingestion; [Krieger, p. 135-41]

(2R,6aS,12aS)-1,2,6,6a,12,12a… carcinogenicity classification

Under the conditions of these 2-year feed studies, there was equivocal evidence of carcinogenic activity of rotenone for male F344/N rats, as indicated by an increased incidence of parathyroid gland adenomas (uncommon tumors). There was no evidence of carcinogenic activity in female F344/N rats fed diets containing 38 or 75 ppm rotenone. There was no evidence of carcinogenic activity for male or female B6C3F1 mice fed diets containing 600 or 1,200 ppm rotenone for 2 years. The decreased incidence of liver neoplasms in male mice may have been related to the administration of rotenone.

Cancer Classification: Group E Evidence of Non-carcinogenicity for Humans

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.
