Results and discussion
- Preliminary study:
- One female rat the test substance was given in a 2000 mg/kg bw dose. Slight signs of toxicity were observed in this rat.
One, 3 and 6 hours after the application of the test article a pinched abdomen and piloerection were seen in this animal. On days 1 and 2 piloerection only was observed. From day 3 until the end of the observation period no abnormalities were seen. The post mortem inspection revealed no abnormalities.
On the basis of the results from the sighting study the main study was carried out with one group consisting of five male and five female rats given a dose of 2000 mg/kg bw.
Effect levels
- Sex:
- male/female
- Dose descriptor:
- discriminating dose
- Effect level:
- 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: One, 3 and 6 hours after the application of the test article a pinched abdomen and piloerection were seen in all animals. On day 1 only piloerection was observed in all animals. From day 2 until the end of the observation period no abnormalities were seen
- Gross pathology:
- No macroscopic pathologic abnormalities were noted in the animals (5 males and 5 females) examined on the last day of observation.
Applicant's summary and conclusion
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.
