Additional information
Acute oral toxicity in rat:
The acute oral toxicity of the test article in 5 male rats and 5 female rats was tested according to OECD guideline 401 (RCC 1990). A single dose of 2000 mg/kg body weight was administered through gavage. The rats were observed for a total period of 15 days. No mortality and abnormal clinical signs occurred and normal body weight gain was found in this study. At autopsy, no macroscopic organ changes were observed. LD50 rat oral = > 2000 mg/kg
Acute dermal toxicity in rat:
A single dose of 2000 mg/kg body weight, was administered to the backs of 5 male and 5 female rats according to OECD guideline 402 (RCC 1990). The test article was applied evenly over an area of 10% and covered with a semi-occlusive dressing. The rats were exposed to the test article for 24 hours. The rats were then observed for a further 15 days. Local effects were scales and discoloration (blue skin). No mortality and no systemic symptoms were observed. LD50 rat dermal = > 2000 mg/kg
Acute inhalation toxicity:
No study available
Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available experimental test data is reliable and suitable for the purpose of classification under Directive 67/548/EEC. Based on the data, classification for acute toxicity is not warranted under Directive 67/548/EEC.
Classification, Labeling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for the purpose of classification under Regulation (EC) No.1272/2008. Based on the data, classification for acute toxicity is not warranted under Regulation (EC) No.1272/2008.
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.
