Applicant's summary and conclusion
- Conclusions:
- Based on the results of this study, the test item requires classification with R38 according to Dangerous Substance Directive (67/548/EEC).
- Executive summary:
The primary skin irritation potential of the test article was investigated by topical semi-occlusive application of 0.5 ml 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, as well as 7, 10 and 14 days after removal of the dressing. The mean score was calculated across 3 scoring times (24, 48 and 72 hours after patch removal) for each animal for erythema/eschar grades and for oedema grades, separately. The mean erythema/eschar score of the the three animals was 2.00, 2.00 and 2.00, respectively and the mean oedema score was 2.00, 0.33 and 1.67, respectively. Very slight to well-defined erythema was observed in two animals from 1 hour to 10 days after treatment and in the other animal from 1 hour to 7 days after treatment. Swelling was also noted at the test site of all animals during the observation period. Very slight to slight swelling was present in two animals from the 1 - to 72-hour reading and in the other animal at both the 1 - and 24-hour readings. Scaling was evident at the test site of all animals on day 7 and persisted in two animals up to termination on day 14. 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.
