Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test substsance caused slight, reversible irritation (iris score = 0, cornea, chemosis and redness scores <1), which does not require classification.
Executive summary:

The substance was tested undiluted in an acute eye irritation with rabbits test according to OECD Guideline 405. The test substsance caused slight, reversible irritation (iris score = 0, cornea, chemosis and redness scores <1), which does not require classification.
