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
