- Irritant / corrosive response data:
- Slight erythema and edema reactions (score 1) were observed one hour after removing the bandages in one animals. All other readings at 24, 48 and 72h timepoints in all animals were zero.
- Other effects:
- A slight loss of weight was observed in one animal at the end of the observation period on day 3.
Applicant's summary and conclusion
- Interpretation of results:
- other: EU GHS criteria not met
- Conclusions:
- Under the experimental conditions employed the test item induced slight erythema and edema reactions when applied to the clipped albino rabbit skin. The reactions were observed only one hour after removing the bandages. Because the mean values of the recordings 24 to 72 hours after application are scored zero, the test item is considered to be not irritating to the skin.
