- Details on study design:
- The fur was removed by shaving the dorsal area of the trunk of 3 rabbits 24 hours prior to use. Only animals with healthy skin were used.
A dose of 500 mg was applied to the test sits (pulverized test substance moistened with water) and then covered with a gauze patch held in place with a semi-occlusive dressing. After 4 hours, the patches were removed and each site was assessed; the severity of the reaction was recorded 60 min, 24, 48, and 72 hours after patch removal.

- 4
- Irritant / corrosive response data:
- No redness or swelling was observed on the skin of any of the 3 rabbits 60 min, 24, 48, and 72 hours after exposure to the test material. Therefore, the primary irritation score was 0.0.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance was classified as not irritating to rabbit's skin on the basis of the scores which were 0.0 out of a possible 4.
- Executive summary:
In a skin irritation test performed according to OECD 404 none of the three rabbits exposed for 4 hours under semi-occulsive conditions to the test substance showed any skin reaction (score 0.0 for erythema and edema). Thus, the test substance is not irritating to the skin of rabbits.

- Amount(s) applied (volume or weight with unit): 100 mg - Duration of treatment / exposure:
- after administering the test item into the conjunctival sac of the right eye of 3 rabbits the lid was then gently held together for about one second in order to prevent loss of the test material

Additional information
In a skin irritation test performed according to OECD 404 none of the three rabbits exposed for 4 hours under semi-occulsive conditions to the test substance showed any skin reaction (score 0.0 for erythema and edema). Thus, the test substance is not irritating to the skin of rabbits.

Justification for classification or non-classification
Based on a study on rabbits following OECD 404 no irritation is warranted for skin irritation.
Based on a study on rabbits following OECD 405 the test substance should be regarded as severely damaging the eye (Eye Damage 1, H319) according to EC 1272/2008.
