- Executive summary:
Test Guidance
In a study similar to US EPA OPP 81-4, ground test chemical (0.1 g) was placed into the conjunctival sac of one eye of each of 6 New Zealand White rabbits. The untreated eye acted as a control. The eyes were not washed after instillation. Treated eyes were examined at 1, 2, 3, 4 and 7 days after treatment.
Results
Slight conjunctival effects (redness and chemosis) were noted in all 6 animals. Effects were reversible by the 4 -day observation except for redness in one animal which persisted to the 7-day observation. Effects which had reversed at the 4 -day observation reoccurred at the 7 -day observation (2/5 animals (redness) and 3/5 animals (chemosis). This was considered to be due to the presence of the test material throughout the full 7 -day period in comparison to the current OECD guideline which requires washing of the eye at the 1 hour exposure observation if the material has not been removed by physiological mechanisms.
Conclusion
The test material is not an irritant to the eye of rabbits. The test material is not classified in accordance with Regulation (EC) No. 1272/2008
