- TEST SITE
An area of at least 36 cm² was shaved on both flanks of the animals approximately 24 hours before treatment. A gauze patch (approx. 12-16 cm²) bearing 0.5 g of the test item was applied to the right flank of each animal. A control gauze patch was applied to the contralateral flank. The patches were loosely covered with an aluminum foil (approx. 36 cm²) and held in place for 4 hours by an adhesive tape, followed by removal of the gauze patches.
SCORING SYSTEM:
The skin reaction was assessed according to the OECD scoring system at 1, 24, 48 and 72 hours intervals (after the removal of the gauze patches).

The body weight gain of all rabbits was similar. No acute clinical symptoms were observed in the animals during the test period, and no mortality occurred.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Executive summary:
In a primary dermal irritation study three New Zealand White rabbits were dermally exposed to 0.5 g test item (as described in section 1.2). Test sites were covered with a semi-occlusive dressing for 4 hours. Animals were then observed for 3 days and the irritation was scored at 1, 24, 48, and 72 hour(s). In this study, no signs of dermal irritation were observed. Thus, the test item was not irritating to the rabbit skin under the conditions of this study.
