Materials and methods
- Principles of method if other than guideline:
- The LD50 was determined by a method closely akin to the one-day cuff method of Draize et al. (1944) using groups of 4 male albino New Zealand rabbits. The fur was removed by clipping and the dose was retained beneath an impervious plastic film (i.e. occlusive). The animals were immobilized/exposed for 24 hours. Afterwards, the film was removed and the animals were observed for 14 days.
- GLP compliance:
- no
- Test type:
- standard acute method
- Limit test:
- no
