- Irritant / corrosive response data:
- No skin irritation was observed throughout the study.
- Other effects:
- - no mortality was observed.
- no clinical signs were observed during the observation period.
- behaviour was calm and alert. It did not differ from rabbits, which were not involved in the study.
- rabbits gained body weight throughout the observation period, except for one male rabbits which lost weight on observation day 1. Afterwards, the male rabbit also gained throught the observation period.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance is not irritating to the skin.
According to Regulation (EC) No 1272/2008 and subsequent adaptations, the substance does not require classification as skin irritant.
