Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- Considering the reported data of this irritation study it can be stated that the test item L-Benzyladrianol Base schowed no irritation/
corrosive effects. - Executive summary:
In this irritation study the test item L-Benzyladrianol Base was applied to one side of the closely clipped backs of 3 rabbites
(strain NZW) at a dose of 0.5 g per application site. The untreated other side served as control.
The application side was covered with a semi-occlusive bandage for a 4 hour-contact time.
Observations were recorded and compared to the control sites,1 h, 24 h, 48 h and 72 hours afetre removal of the dressing.
The test item L-Benzyladrianol Base schowed no irritant effects on the intact skin after a contact time of 4 hours.
No other clinicla sings of toxicity were found.
