Materials and methods
- Principles of method if other than guideline:
- Penetration o f rabbits skin is estimated by a technique closely akinto the one-day cuff method of Draize and associates, using groups of 4 male albino New Zealand rabbits weighing 2.5 to 3.5 kg . the fur was removed from the entire trunk by clipping and the dose is retainded beneath an imperious plastic film. The animals were immobilized during tge 24-hour contact period, after which the film was removed and the rabbits are caged for subsequent 14 day observation period
- GLP compliance:
- no
- Test type:
- other: acute dermal toxicity study
