Materials and methods

Test guideline

Qualifier:

no guideline followed

Principles of method if other than guideline:

To evaluate the eye irritation potential for the test substance, the right eyes of 4 animals were exposed to the test item for 24 hours. Left eye served as control. The eye's animals were examinated 24 hours and 7 days after exposure, and the score of irritation were calculated.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Test substance produced a mild reversible ocular irritation.

Executive summary:

To evaluate the eye irritatiion potential fo the test substance, the right eyes of 4 animals were exposed to the test item for 24 hours. Left eye served as control. The eye's animals were examinated 24 hours and 7 days after exposure, and the score of irritation were calculated. Slight effects were observed on the conjunctivae (redness and chemosis). These effects were reversible within 7 days. However no effect was observed on iritis and cornea. Based on the results, the test substance produced a mild reversible ocular irritation.
