Applicant's summary and conclusion

Interpretation of results:
other: Not classified
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
Even though the test material showed signs of causing irriattion to the eye in New Zealand White Rabbits, however the results were not significant enough to classify the syubstance as an irritant according to the Globally Harmonised system (GHS) or the Dangerous Substances Directive (DSD).
Executive summary:

The test material was not clasisifed for eye irrritation according to the Globally Harmonised System (GHS) or the Dangerous Substances Directive (DSD).
