-Necropsy of survivors performed: yes
All animals surviving to the end of the observation period were sacrificed by oxygen/carbon dioxide asphyxiation and subjected to necropsy.

At periodic intervals on the day of dosing (day 1) and once daily thereafter for 14 days. All signs of reaction to treatment were recorded with particular attention paid to changes in the skin (treated skin), fur, eyes and mucous membranes, as well as to behaviour pattern, tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma.

- Mortality:
- No animals died during the study period.
- Clinical signs:
- Lethargy was noted in three animals during treatment on day 1. Throughout the study, the treated skin area of all the animals was discoloured
yellow/brown by the test substance. One male showed erythema on days 2 and 3 and 1 male showed crusts on days 4 and 5. - Body weight:
- Lower than expected body weight gain was shown by the animals over the first week of the study. However, all showed improved body weight gain over the second week of the study.
- Gross pathology:
- Macroscopic post mortem examination of the animals at termination did not reveal any abnormalities.
Applicant's summary and conclusion
- Interpretation of results:
- other: not classifed according to the CLP (EC 1272/2008)
- Conclusions:
- The dermal LD-50 value in rats of either sex was established to exceed 2000 mg/kg body weight.
- Executive summary:
The purpose of this study was to assess the toxicity of the test article when administered to rats as a single dermal dose.
The study was carried out in accordance with OECD Guideline No. 402, "Acute Dermal Toxicity" and EEC Directive 84/449/EEC, Part B.3, "Acute Toxicity - Dermal".
The substance was dermally applied to five rats of each sex at 2000 mg/kg body weight. Macroscopic examination was performed at the end of the experimental period.
No animals died during the study.
Lethargy was noted in three animals on the day of treatment (day 1) only. Lower than expected body weight gain was shown by the animals over the first week of the study. However, all showed improved body weight gain over the second week of the study.
The treated skin area of all the animals showed yellow/brown discolouration by the test substance throughout the study. One male showed erythema on days 2 and 3 and 1 male showed crusts on days 4 and 5. Macroscopic post mortem examination of the animals at termination did not reveal any abnormalities.
The dermal LD-50 value in rats of either sex was established to exceed 2000 mg/kg body weight.
According to the EEC criteria for classification and labelling requirements for dangerous substances (EEC Directive 83/467/EEC; Annex VI of the EEC Directive 67/548/EEC), the substance cannot be classified and has no obligatory labelling requirement.
