Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Not irritant
- Executive summary:
Method:
The eye irritation was determined in an irritation test on rabbits according to the "Hazardous Substances Regulations" under the U.S.A. Federal Hazardous Substances Labelling Act Sect. 191.12 (February 1965), similar to OECD guideline 405.
Observation:
A slight to mild conjunctival reaction was seen in all treated eyes from 1 hour after application of the compound. The washed eyes were slightly less severe and returned to normal by day 6.
Result:
Not irritant.
