Additional information
Acute oral toxicity
In a standard acute oral toxicity study performed similarly to OECD TG 401, groups (5 rats/dose/sex) of overnight fasted Tif Raif rats were administered the test substance (no data on purity) via gavage. The test substance was administered at doses of 4640, 7750 and 10000 mg/kg bw in polyethylene glycol. Animals were subsequently observed for a period of 14 day in which time clinical signs of toxicity and cases of mortality were noted. Death occurred only in the mid dose level with 1 out of 10 animals found dead. No mortality occurred at the low and high dose groups. Hence the LD50 is higher than 10,000 mg/kg bw. Clinical signs of toxicity - seen in animals of all doses - set in 2 hours post application and lasted 8 days. These included; dyspnoea, exophthalmus, curved position and ruffled hair (1976).
Acute dermal toxicity
In a limit test performed pursuant to the protocols of the OECD Test Guideline 402, the test article (low purity) was applied in a semi-occlusive fashion for 24 hours to the shaved skin of 5 (8 -11 weeks old) Hanlbm: WIST rats/sex at a dose level of 2,000 mg/kg bw. Animals were then observed for 14 days. No mortality was registered in the study. Neither clinical signs of systemic toxicity nor local irritation effects at the application site were observed during the 14 day observation period. Necropsy revealed no gross abnormalities. As no deaths occurred in the study, the LD 50 of the test article in rats is higher than 2,000 mg/kg bw (1997).
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for the purpose of classification. Based on the criteria laid down in Regulation (EC) No.1272/2008, classification for acute toxicity is not warranted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
