- Irritant / corrosive response data:
- Examination of the eyes revealed very slight conjunctival redness in six out of six rabbits one hour after dosing. Three of the six rabbits had very slight conjunctival chemosis and five out of six had very slight irritation of the iris one hour after dosing. Irritation of the iris was resolved in all animals by 24 hours post-instillation, and chemosis was resolved in all animals by 48 hours after dosing. Conjunctival redness was resolved in all animals by seven days post dosing, and the test was terminated on test day seven as per guidelines.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Conjunctival redness: Very slight (resolved by 7 days)
Conjunctival chemosis: Very slight (resolved by 48 hours)
Iris: Very slight (resolved by 24 hours) - Executive summary:
The test substance was assessed for the potential to cause ocular irritation after instillation of a 0.1 g aliquot into the conjunctival sac of the right eye of six New Zealand White rabbits. The study was conducted according to OECD guideline 405 and US EPA guideline 81-4.
Examination of the eyes revealed very slight conjunctival redness in six out of six rabbits one hour after dosing. Three of the six rabbits had very slight conjunctival chemosis and five out of six had very slight irritation of the iris one hour after dosing. Irritation of the iris was resolved in all animals by 24 hours post-instillation, and chemosis was resolved in all animals by 48 hours after dosing. Conjunctival redness was resolved in all animals by seven days post dosing, and the test was terminated on test day seven as per guidelines.
