REMOVAL OF TEST SUBSTANCE
- Washing (if done): tepid tap water
- Time after start of exposure: 24 h - Duration of exposure:
- 24 h
- Doses:
- 200 mg/kg and 2000 mg/kg
- No. of animals per sex per dose:
- 2
- Control animals:
- not specified
- Details on study design:
- The hair was removed from the back of each rabbit with an electric clipper. The skin of one male and one female rabbit in each group was abraded with a scalpel blade.
The test material was applied only once, following which the site of application was occluded and wrapped with a gauze bandage. 24 hours later the bandages were removed and the backs washed with tepid tap water.
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: at the beginning of the study, 7 days and 14 days after compound application
- Necropsy of survivors performed: no - Statistics:
- none
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD0
- Effect level:
- >= 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- None
- Clinical signs:
- other: None
- Gross pathology:
- None
- Other findings:
- At 24 hours following application, erythema (moderate to marked) and edema (slight to moderate) was observed in all rabbits. Additionally blanching was observed. Desquamation was noted during the 14 day observation period. Each of the rabbits showed gains in body weight during the observation period.
Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The dermal LD50 is > 2000 mg/kg. Thus, the test item is not considered a toxic substance by the dermal route of administration.
- Executive summary:
In an acute dermal toxicity study groups of male and female New Zealand white rabbits (2 male and 2 females) were dermal exposed in a limit test to Lupersol 223(Bis-(2 -ethylhexyl)) peroxycarbonate for 24 hours at doses of 200 and 2000 mg/kg bw. Animals then were observed for 14 days. At 24 hours following application, erythema (moderate to marked) and edema (slight to moderate) was observed in all rabbits. Additionally blanching was observed. Desquamation was noted during the 14 day observation period. Each of the rabbits showed gains in body weight during the observation period.
The dermal LD0 is 2000 mg/kg bw. Lupersol 223 (Bis-(2 -ethylhexyl)peroxycarbonate) is not toxic by the dermal route.
