Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- not determinable due to absence of adverse toxic effects
- Mortality:
- No deaths occurred during the whole study
- Clinical signs:
- other: No symptoms were observed after administration of 2,000 mg/kg bw. The skin of the animals showed substance related discolorations (reddish). From Day 8 until the end of the study no symptoms were observed.
- Gross pathology:
- The animals killed at the end of the observation period showed no macroscopically visible changes.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the test substance was determined to have the median lethal dermal dose value (LD50) of greater than 2000 mg/kg bw.
- Executive summary:
An acute dermal toxicity for the test subsatnce was conducted according to OECD guideline 402, EU method B.3 and EPA OPPTS 870.1200 and in compliance with GLP.
After administration of 2000 mg/kg bw dermally, the animals were observed for 14 d for clinical signs, mortality and body weight change. No clinical signs and mortality occurred. The skin of the animals showed substance related discolorations (reddish) from Day 2 up to Day 7 of the study. Two female animals showed loss of body weight during the first week of the study, which returned to normal until the end of the study. One female animal showed a loss of body weight at the end of the study. In the other animals development of body weight was not impaired. Development of body weight in male animals was not impaired. All animals were sacrificed at the end of the observation period. They showed no macroscopically visible changes.
Under the test conditions, the test substance was determined to have the median lethal dermal dose value (LD50) of greater than 2000 mg/kg bw.
