Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- none
- Clinical signs:
- No systemic clinical signs were observed during clinical examination. No local skin effects were observed in the animals. Only on study day 1, blue test item residues were noted on the application area.
- Body weight:
- The mean body weight of the animals increased within the normal range throughout the study period with three exceptions in the female group. These females showed a stagnation of body weight within the first week, but body weights were within the normal range during the second week. Due to the fact that stagnation of body weight is commonly known for females dermally applied, this stagnation is considered to be unspecific.
- Gross pathology:
- No macroscopic pathologic abnormalities were noted in the animals (5 males and 5 females) examined on the last day of observation.
