Applicant's summary and conclusion

Interpretation of results:
highly irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Based on the highly irritating eye effects observed the test substance has to be classified with "Risk of serious damage to eyes" in accordance with Directive 67/548/EEC (DSD).
Executive summary:

Eye injury in rabbits is recorded in a 10-grade ordinal series and is based upon the degree of corneal necrosis that results from instillation of various volumes and concentrations of chemical, as detailed by Carpenter and Smyth. Grade 1 in the Table indicates at most a very small area of necrosis resulting from 0.5 ml of undiluted chemical in the eye. Grade 5 indicates a so-called severe burn from 0.005 ml, and Grade 10 indicates a severe burn from 0.5 ml of a 1% solution in water or propylene glycol.
