Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Cracked Distillate is not irritating to the rabbit eye.
Executive summary:

The eye irritant potential of Cracked distillate (CAS 68477-40-7) was investigated in 3 albino rabbits. Slight or moderate redness and chemosis was seen in all three rabbits which recovered within 72 hours.

It can be concluded that Cracked distillate (CAS 68477-40-7) is not irritating to the rabbit eye and no classification is warranted under Dir 67/548/EEC or under GHS/CLP.
