Constituent 1
Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Sex:
- male
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Weight at study initiation: 2.5 - 3.5 kg
Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- not specified
- Details on dermal exposure:
- The fur of the male albino New Zealand rabbits was removed from the entire trunk by clipping, and the dose is retained beneath an impervious plastic film.
The animals were immobilized during the 24-hours contact period, after which the film is removed and the rabbits are caged for the subsequent 14-Day observation period. - Duration of exposure:
- 24 h
- Doses:
- no data
- No. of animals per sex per dose:
- 4 males
- Control animals:
- not specified
- Details on study design:
- - Duration of observation period following administration: 14 days
- Statistics:
- Based upon mortalities during a 14-day observation period, the most probable LD50 value and its fiducial range are estimated by the method of Thompson* using the tables of Weil**.
