Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- No effects.
- Clinical signs:
- other: No systemic effects.
- Gross pathology:
- No effects.
- Other findings:
- Moderate to severe dermal irritations at the treatment site were observed following removal of the dressings. 24 h after dermal application of the test substance four male and three female animals showed inflammation of the treated skin. One male and two females showed no skin lesions.
48 h after application an induration of the skin lesions occured and 72 h after application a scab formation was noticed. The scab was fallen off 6 days later in male animals and 12 days later in female animals. On day 14 only one female animal showed residual scabs and a slightly scarred skin.
Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008.
