Results and discussion
In vivo
Resultsopen allclose all
- Irritation parameter:
- erythema score
- Basis:
- mean
- Time point:
- 24/48/72 h
- Max. score:
- 4
- Remarks on result:
- not determinable
- Remarks:
- due to strong staining, no erythema score could be derived
- Irritation parameter:
- edema score
- Basis:
- mean
- Time point:
- 24/48/72 h
- Score:
- 0
- Max. score:
- 4
- Remarks on result:
- no indication of irritation
- Irritant / corrosive response data:
- Due to a strong staining of the skin at the treated surface, no erythema score could be determined. However, no edema occured and no erythema was observed after 8 d.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance did not cause any signs of irritation on rabbit skin. Although no erythema score could be determined at 24/48/72 h due to strong staining, no signs of irritation were observed after 8 d.
