Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Sample 507-43 gave a negative result for eye irritation, according to the definition given in the Code of Federal Regulations of the U.S.A.
- Executive summary:
The procedure employed was that prescribed by The Consumer Product Safety Commission of the U.S.A. in The Code of Federal Regulations, Title 16, Section 1500.42, a transcript of which is attached as an Appendix to the full study report.
For the test, 79 mg of sample 507-43 was instilled into one eye of each six animals, while the untreated eye was used as concurrent control.
The numerical scores awarded to the ocular reactions elicited by 507-43 are given in Table 1: none of the animals gave a positive reaction and only mild conjunctival reactions were observed in all six animals.
Sample 507-43 gave a negative test for eye irritation, according to the definition given in the Code of Federal Regulations of the U.S.A.
