Administration / exposure

Type of coverage:
occlusive
Vehicle:
water
Details on dermal exposure:
The method of Noakes and Sanderson was used. Groups of rats of each sex, aged 12-13 weeks, were used at each dose level. The test material was placed onto the shorn dorsa-lumbar skin and bandaged into contact with the skin using an impermeable dressing of aluminium foil and waterproof plaster.
Duration of exposure:
24 hours
Doses:
1000 mg/kg
No. of animals per sex per dose:
4 male, 4 female
