- Irritant / corrosive response data:
- Initial test:
Redness of conjunctivae, secreta and chemosis were observed in 1 - 24 hours after administration. Corneal opacity and iris change were not observed.
Control site was no eye irritation.
Confirmatory test:
Redness of conjunctivae, chemosis and secreta were observed sporadically in 1 to 72 hours after administration. Comeal opacity and iris change were not observed.
Control site was no eye irritation. - Other effects:
- Clinical Signs:
During the study periods, no treatment-related dead and clinical signs were found.
Body Weights:
No test substance-related body weight changes were detected.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- As the evaluation of the eye reactions, in the initial test redness of conjunctivae, chemosis and secreta were observed in 1 - 24 hours after administration. Comeal opacity and iris change were not observed.
In the confirmatory test redness of conjunctivae, chemosis and secreta was observed sporadically in 1 - 72 hours after administration. Comeal opacity and iris change were not observed.
No eye irritation was found from control site, (initial test, confirmatory test). In case of confirmatory test, ocular irritation index of Comeal opacity and iris were 0. The ocular irritation index of redness of conjunctivae and chemosis were 0.33, 0.44 respectively. The result of control site was zero.
Based on the results of this study , eye irritation / corrosion ofthe test substance Copper cyanide(Copper(I) cyanide) in New Zealand White Rabbits was verified non-irritation / non¬corrosion substance.
