Applicant's summary and conclusion

- GHS criteria not met
- Conclusions:
- substance not toxic after dermal application
- Executive summary:
The study was performed as a limit test according to OECD guideline 402. Wistar rats (5 males and 5 females) were randomly selected for the study. The group was exposed to a single dermal dose of 2000 mg/kg b.w. for 24 hours followed by an observation period of 14 days. During the study clinical signs of reaction to the treatment were recorded daily. Body weight was recorded once a week. After the two-week observation period the animals were killed and subjected to a gross necropsy examination. All animals survived the application and did not reveal any signs of toxicity. The animals gained the expected body weight. No skin reactions at the application site were observed. No macroscopic findings were observed at necropsy. These results indicate that the test substance has no significant toxic effect in the rat following dermal administration of a single dose at a level of 2000 mg/kg.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
