TEST SUBSTANCE PREPARATION
The powdery test substance was moistened with distilled water, immediately before application.

TEST SITE
Approximately 24 hours before treatment, the dorsal fur was shaved with electric clippers, exposing an area of approximately 150 square centimeters (10x15 cm). Whenever considered necessary the skin areas concerned were re-clipped at least 3 hours before the observations, to facilitate scoring

The test substance was applied to the skin of one flank, using a patch of 2x3 cm. A similar patch (but without test substance and water) was applied to the contralateral flank, to act as a procedural control. Both patches were mounted on Micropore tape, which was wrapped around the abdomen and secured with Coban elastic bandage.

REMOVAL OF TEST SUBSTANCE
Four hours after the application, the dressing was removed and the remaining test substance removed using a tissue moistened with tap-water and subsequently a dry tissue.

OBSERVATIONS (kort allemaal!)
- Mortality/Viability: Twice daily.
- Toxicity: At least once daily.
- Body Weight: Day of treatment (prior to application)
- Necropsy: Not performed.
- Irritation: The skin reactions were assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressings and test substance. The irritation scores and a description of all other (local) effects were recorded.

TREATMENT
On test day 1, the test substance was instilled in the conjunctival sac of one eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of the test substance.
