- Interpretation of results:
- study cannot be used for classification
- Conclusions:
- Under the test conditions, the test substance induced slight to moderate skin irritation in rabbits.
- Executive summary:
In an acute dermal toxicity study (limit test), two rabbits were given a single dermal application of the test material at a dose level of 5000 mg/kg bw. Animals were observed for mortality and clinical signs for 14 days.
No mortality occurred during the study. No clinical signs were observed. Moderate redness was observed in two animals, slight edema in one rabbit and moderate edema in another.
Under the test conditions, the test substance induced slight to moderate skin irritation in rabbits.
This study was conducted according to a non-standard method and adequate scoring of skin effects was not provided, therefore it was not possible to take a decision on the classification based solely on this study.
Acute dermal LD50 of test material was higher than 5000 mg/kg bw

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the dermal LD50 for test substance is higher than 5000 mg/kg bw in rabbits. Therefore, the substance is not classified according to the annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
- Executive summary:
In an acute dermal toxicity study (limit test), two rabbits were given a single dermal application of the test material at a dose level of 5000 mg/kg bw. Animals were observed for mortality and clinical signs for 14 days.
No mortality occurred during the study. No clinical signs were observed. Moderate redness was observed in two animals, slight edema in one rabbit and moderate edema in another. In this study, the dermal LD50 of Tabac absolute was higher than 5000 mg/kg bw in rabbits.
Under the test conditions, the dermal LD50 for test substance is higher than 5000 mg/kg bw in rabbits. Therefore, the test substance is not classified
according to the annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
