Description of key information
The test substance was not irritating to the skin of rabbits (OECD TG 404) and only slightly irritating to the eye of rabbits (OECD TG 405; only 2/3 animals showed score 1 for conjunctivae (redness) after 24 h, fully reversed after 48 h; all other scores zero).

- Duration of treatment / exposure:
- 4 hours
- Observation period:
- Until changes had completely subsided, however for not more than 14 days after application.
- Number of animals:
- 3
- Details on study design:
- Due to a possible irritant potential of the test substance, in the first step only one animal was used and three test patches were applied successively to this animal, as described above. The first patch was removed after three minutes. As no serious skin reactions were observed, the second patch was applied and removed after one hour. At this stage the observations indicated that with respect to animal welfare the exposure can be allowed to extend to four hours, therefore the third patch was applied and removed after four hours and the responses were graded one hour later. The test was completed using two additional animals, exposed for four hours.
TEST SITE
On the day before the test, the fur was shorn on the right and left side from the dorso-lateral area of the trunk of each rabbits. 0.5 mL of the pure liquid test substance was applied to the skin of the animal under a gauze patch. The patch was placed on the dorso-lateral areas of the trunk of each animal and was held in place with non-irritant tape for the duration of the exposure period. Thus, access by the animal to the patch and resultant ingestion of the test substance was prevented.
- Area of exposure: approximately 2.5 cm x 2.5 cm
REMOVAL OF TEST SUBSTANCE
- Washing (if done): The exposed skin area was carefully washed with water without altering the existing response, or the integrity of the epidermis.
- Time after start of exposure: after 4 hours

- 0.1 ml of the pure liquid test substance was placed into the conjunctival sac of one eye of the first animal after having gently pulled the lower lid away from the eyeball. The lids were gently held together for about one second in order to prevent loss of the test compound.
Because of the fact that one hour after treatment a severe irritation was not observed, a further two rabbits were treated as described.
