- Individual edema scores for animal #1 were 2, 4, 3 and 3 for t=4, 24, 48 and 72 hours respectively. Individual edema scores for animal #2, #3, #4, #5 and #6 were 2, 3, 3 and 3 for t=4, 24, 48 and 72 hours respectively.
- All adverse effects were fully reversible within 7 days. - Other effects:
- - A defatting effect was observed: skin sloughed off in ten to fourteen days. There was no in depth injury.
Applicant's summary and conclusion
- Interpretation of results:
- other: Skin irritant Category 2
- Remarks:
- according to Regulation (EC) No 1272/2008 and its amendments.
- Conclusions:
- The substance was tested in a skin irritation study. Based on the results, the substance is considered to be a skin irritant.
- Executive summary:
The substance was tested in a skin irritation study, equivalent to OECD TG 404. Six rabbits were exposed to the substance for 24 hours (instead of the normal 4h). Individual erythema scores for each animal were 4, 3 and 3 for t= 24, 48 and 72 hours respectively. Individual edema scores for animal #1 were 4, 3 and 3 for t=24, 48 and 72 hours respectively, and individual edema scores for animal #2, #3, #4, #5 and #6 were 3, 3 and 3 for t=24, 48 and 72 hours respectively. This resulted in a mean erythema score of 3.3 in all animals and a mean edema score of 3.3 and 3 for animal #1 and animals #2, #3, #4, #5 and #6 respectively (average of scores at 24, 48 and 72 hours). These effects had fully reversed within 7 days. A defatting effect was observed: skin sloughed off in ten to fourteen days, and no in depth injuries were observed. Based on these results, the substance is considered to be a skin irritant.
