- Area of exposure: 2.5 x 2.5 cm
- Type of wrap if used: substance applied on surgical gauze patch, covered with semi-occlusive dressing, wrapped around the abdomen and anchored with tape.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): yes, with lukewarm tap water
- Time after start of exposure: 4 h, at the end of exposure time
OBSERVATION TIME POINTS
1, 24, 48 and 72 h after removal of the test substance
SCORING SYSTEM:
- Method of calculation: The skin reactionwas assessed according to the numerical scoring system listed in the EEC Commission Directive 92/69/EEc, July 31, 1992.
The primary irritation score was calculated by totalling the individual cummulative scores at 24, 48 and 72 h and then dividing by the number of data points.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item did not reveal any irritation potential on the skin of rabbits, tested in this study according to OECD test guideline no. 404 and GLP conditions.
- Executive summary:
The skin irritating potential of the test item was assessed according to OECD TG 404. Three rabbits (1 male and 2 females) were exposed to 0.5 mg test item under semi-occlusive conditions for 4 hours. Yellow staining produced by the colour of the test item on the treated skin was observed in all animals at the 1-hour reading and persisted up to the 48- or 72-hour reading. The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0.
