ENVIRONMENTAL CONDITIONS
- Temperature (°C):22 ±3
- Humidity (%):45-70
- Air changes (per hr):10-15 air changes per hour
- Photoperiod (hrs dark / hrs light): 12 hours light and 12 hours dark.
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- other: The test substance was moistened with bidistilled water
- Controls:
- not specified
- Amount / concentration applied:
- 500 mg
- Duration of treatment / exposure:
- 4 h
- Observation period:
- 1, 24, 48 and 72 hours
- Number of animals:
- 3
- Details on study design:
- TEST SITE
- Area of exposure: 100 cm² (10 cm x 10 cm).
- Type of wrap if used:The dressing was wrapped around the abdomen and anchored with tape.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): The duration of treatment was 4 hours. Then the dressing was removed and the skin was flushed with lukewarm tap water to clean the application site so that any reactions (erythema) were clearly visible at that time.
SCORING SYSTEM: The skin reaction was assessed according to the numerical scoring system listed in the EEC Commission Directive 92/69/EEC, July 31, 1992 at approximately 1, 24, 48 and 72 hours after the removal of the dressing, gauze patch and test item.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Conclusions:
- Based upon the referred classification criteria (EEC Commission Directive 93/21/EEC of April 27, 1993), FAT 60'253/A is considered to be "not irritating" to rabbit skin.
- Executive summary:
The primary skin irritation potential of FAT 60253/A was investigated by topical semiocclusive application of 0.5 g to 6 cm² intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours after removal of the dressing. The scores of each animal at the following reading times (24, 48, 72 hours) were used in calculating the respective mean values for each type of lesion. The test article did not elicit any skin reactions at the application site at any of the observation times (all scores 0). The mean values from 24 to 72 hour were therefore 0 for erythema and 0 for oedema. The test item caused no staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any measuring interval. Based upon the referred classification criteria (EEC Commission Directive 93/21/EEC of April 27, 1993), FAT 60'253/A is considered to be "not irritating" to rabbit skin.
