Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
In an acute eye irritation study in 3 rabbits, conducted in accordance with OECD 405 (2002), EU Method B.5 (2008), EPA OPPTS 870.2400 (1998) and according to GLP principles, irritant effects were observed which were fully reversible within 24 hours. Based on the results of this study, the substance does not need to be classified for eye irritation.
Executive summary:

An acute eye irritation study was conducted in 3 rabbits in accordance with OECD 405 (2002), EU Method B.5 (2008), EPA OPPTS 870.2400 (1998) and according to GLP principles. In none of the animals, any effects on the cornea and iris were observed. Conjunctival redness (score: 1) was observed in all animals after 1 hour. In two animals chemosis (score: 1) was observed after 1 hour. All ocular effects fully reversed within 24 hours. Based on the results of this study, the substance does not need to be classified for eye irritation.
