Details on study design:
Hair was clipped on the dorsal area of the trunk one day before the application of the test substance. An electric hair clipper with a 1 mm cutterhead was used. The test site was median on the dorsal thoracal region.
A cellulose patch with 0.5 g of the test substance (actual concentrations: 496, 504 and 498 mg), spread over an area of approximately 6 cm2 and soaked with 1.5 ml distilled water, was applied to the test site and held in place by fixing marginally with non irritating tape. The application site was covered by a dressing. Access by the animal to the application site was prevented by a plastic collar.
The duration of exposure was 4 hours.
At the end of the exposure period the dressing, the tape with the patch and the collar were removed. Residual test substance was wiped off using wet cellulose tissue.

Acclimatization: 5 to 12 days.
Vehicle:
unchanged (no vehicle)
Controls:
not required
Amount / concentration applied:
0.1 mL equivalent.
Duration of treatment / exposure:
Test substance instillation
The approximate equivalent of 0.1 mL of the test substance was administered per animal into the conjunctival sacs of the right eyes by gently pulling the lower lids away from the eyeballs for instillation. The eyes were held closed for about one second to prevent a loss of test substance. The weighed amounts of the individual doses were 68, 68 and 66 mg.
The left eyes remained untreated and served as a control.

Observation period (in vivo):
Eye examinations
Both eyes of the animals were examined within 24 hours before the instillation and approximately I, 24, 48 and 72 hours p.a.. The whole eyes, especially the corneae, the irises and the conjunctivae were examined, using an otoscope lamp.
Number of animals or in vitro replicates:
3
Details on study design:
The test substance was dosed first to one animal. As no evidence for a serious damage to the eye of this animal was found until 72 h p.a. (no corrosive effect), the test substance was administered to the other two animals too.

The animals were observed for other than local changes at all observation times too.
