Irritant / corrosive response data:
No skin findings were noted in all animals.
Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Considering the described cutaneous reactions as well as the average score for irritation, the test substance does not give indication of an irritant property to the skin under the test conditions chosen.
Executive summary:

The potential of the test substance to cause acute dermal irritation or corrosion was assessed by a single topical application of 0.5 g of the test substance to the intact skin of 3 White New Zealand rabbits for 4 hours under semiocclusive dressing. After removal of the patch the application area was washed off. The cutaneous reactions were assessed approximately 1, 24, 48 and 72 hours after

removal of the patch. No skin findings were noted in all animals; thus the study was terminated after 72 hours. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for erythema and for edema. Considering the described cutaneous reactions as well as the average score for irritation, the test substance does not give indication of an irritant property to the skin under the test conditions chosen.

Executive summary:

The potential of the test substance to cause damage to the conjunctiva, iris or cornea was assessed in 3 White New Zealand rabbits. The animals were subjected to a double ocular application of 0.1 ml bulk volume (about 9 mg) of the test substance, corresponding to an amount of 18 mg administered. About 24 hours after application the eye was rinsed with tap water. The ocular reactions were assessed approximately 1, 24, 48 and 72 hours after application. Moderate erythema, slight swelling of the eye lids and slight discharge was 0 observed in all animals 1 hour after application. The conjunctival reactions were reversible in all animals within 72 hours after application at latest. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity, for iris and for chemosis and 0.4 for conjunctival redness. Considering the described ocular reactions as well as the average score for irritation, the test substance does not give indication of an irritant property to the eye under the test conditions chosen.

Additional information

Skin

A GLP-compliant skin irritation test was performed with three New Zealand White rabbits according to OECD 404 (Notox, 1999). A 4-hour semiocclusive exposure to approximately 0.5 g of the test material moistened with water produced no effects during the observation period of 3 days on the treated sites of the animals. No skin findings were noted in all animals; thus the study was terminated after 72 hours. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for erythema and for edema. In conclusion, considering the described cutaneous reactions as well as the average score for irritation, the test substance does not give indication of an irritant property to the skin under the test conditions chosen.

Eye

A GLP-compliant eye irritation test was performed with three New Zealand White rabbits according to OECD 405 (BASF, 2000).

The animals were subjected to a double ocular application of 0.1 ml bulk volume (about 9 mg) of the test substance, corresponding to an amount of 18 mg administered. About 24 hours after application the eye was rinsed with tap water. The ocular reactions were assessed approximately 1, 24, 48 and 72 hours after application. Moderate erythema, slight swelling of the eye lids and slight discharge was 0 observed in all animals 1 hour after application. The conjunctival reactions were reversible in all animals within 72 hours after application at latest. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity, for iris and for chemosis and 0.4 for conjunctival redness. In conclusion, considering the described ocular reactions as well as the average score for irritation, the test substance does not give indication of an irritant property to the eye under the test conditions chosen.
