- Irritant / corrosive response data:
- Injection of the conjunctival blood vessels or a crimson-red conjunctival appearance with or without very-slight discharge was evident in all animals one hour after instillation. Conjunctival injection or a crimson-red conjunctival appearance was apparent in two animals during the next three days. One animal was overtly normal 24 hours after instillation, the remaining two were overtly normal after one week.
- Other effects:
- - Lesions and clinical observations: There was no sign of toxicity or ill health in any rabbit during the observation period.
- Ophthalmoscopic findings: not determined
- Histopathological findings: not determined
- Effects of rinsing or washing: not applicable
- Other observations: Instillation of the test substance gave rise to practically no or a slight initial pain response.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Installation into the eyes of rabbits caused mild, transient conjunctival irritation which resolved within the post observation period. The substance is therefore not considered to be irritating to eyes.
- Executive summary:
A GLP-compliant Acute eye irritation/corrosion study according to OECD TG 405 was performed to assess the eye irritation potential of the test substance to the rabbit. Three rabbits were each administered a single ocular dose of a volume of 0.1 ml of the test substance weighing approximately 70 mg and observed for eight days after instillation. Injection of the conjunctival blood vessels or a crimson-red conjunctival appearance with or without very-slight discharge was evident in all animals one hour after instillation. Conjunctival injection or a crimson-red conjunctival appearance was apparent in two animals during the next three days. One animal was overtly normal 24 hours after instillation, the remaining two were overtly normal after one week. Instillation of the test substance gave rise to practically no or a slight initial pain response. As only mild, transient conjunctival irritation which resolved within the post observation period was observed, the substance is not considered to be irritating to eyes.
