Description of key information
Skin Irritation
The primary skin irritation potential of the test item was investigated according to OECD test guideline no 404. The test item (0.5 g) was applied to the intact skin of three New Zealand White rabbits under semi-occlusive conditions for four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours after removal of the test item. A red discoloration was noted on the treated area. No skin reactions, neither erythema nor edema, were observed at any time point (score 0). No signs of systemic toxicity were observed.
Ocular Irritation
The primary eye irritation potential of the test item was investigated according to OECD guideline no 405. The test item (0.1 g) was applied to the intact eye of three New Zealand White rabbits for 1 h. Reddening of the conjunctivae was noted in all three animals 1 h after the tratment and persisted up to 48 h in two animals. Slight swelling was noted in one and slight occular discharge was noted in two animals in the 1 h reading.
The individual mean scores calculated across the three scoring times (24, 48, 72 h) were for corneal opacity 0.0 (three animals), for iris 0.0 (three animals), for conjunctivae redding 0.0, 0.7 and 0.7 and for chemosis 0.0 (three animals).
No abnormal findings were observed in the treated eye of any animal 72 h after treatment.
There was no indication of systemic toxicity.
