Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- According to U.S. EPA § 163.81-4, Federal Register, Vol. 43, No. 163 (1978), TK 12871 was found to cause a minimal irritation when applied to the rabbit eye mucosa. Therefore, TK 12871 was not met a category based on GHS criteria.
- Executive summary:
This test using the procedures outlined in the CIBA-GEIGY Study Plan for 810282 and U.S. EPA § 163.81-4, Federal Register, Vol. 43, No. 163 (1978). The test material in an amount of 0.1 ml was inserted into the conjunctival sac of the left eye of the rabbits and the lids were gently closed for a few seconds. The right eye was not treated and served as an untreated control. In 3 of the 6 rabbits approximately 30 seconds after treatment the treated eye was flushed with 10 ml of physiological saline. The eye irritation was appraised with a slit-lamp on day 1, 2, 3, 4 and 7 and was scored for each individual rabbit. TK 12871 was found to cause a minimal irritation (primary irritation index 0.7) when applied to the rabbit eye mucosa. When the application site was rinsed, the irritation was found to be minimal (primary irritation index 0.9).
