- Irritant / corrosive response data:
- 1-hour observation: Moderate conjunctival irritation was noted in all treated eyes.
24-hour observation: Minimal conjunctival irritation noted in all treated eyes
48-hour observation: Minimal conjunctival irritation noted in one treated eye; other two eyes appeared normal
72-hour observation: All treated eyes appear normal. - Other effects:
- Immediately following administration of the test material to the conjunctival sac, Initial Pain Reaction (IPR) scores were '2' ('slight initial pain - rabbit blinks and tries to open eye, but reflex closes it') for each animal.
No other effects were reported.
Any other information on results incl. tables
There was no evidence of corneal opacity or iritis in any animal at any time point.
Level 2 conjunctival redness was seen in each treated eye at the 1-hour observation, decreasing to Level 1 conjunctival redness in each treated eye at the 24-hour observation, one treated eye at the 48-hour observation and no treated eyes at the 72-hour observation.
Level 2 conjunctival oedema (chemosis) was seen in one treated eye at the 1-hour observation, decreasing to Level 1 by 24 hours and zero by 48 hours. In the other two treated eyes, Level 1 chemosis was observed at the 1-hour observation, but was absent by the 24-hour observation.
The average conjunctival redness scores and the average conjunctival oedema scores (mean average of the 24, 48 and 72-hour observation scores) were each less than 2 in each animal.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information based on EU CLP Regulation 1272/2008 as amended Criteria used for interpretation of results: EU
- Executive summary:
The test material was evaluated for ocular irritancy in a GLP study conducted according to OECD Test Guideline 405.
0.1 ml (approximately 58 mg) of test material was applied to the conjunctival sac of one eye of a New Zealand white rabbit. After consideration of the ocular responses produced, two additional rabbits were treated. The animals were observed for signs of ocular irritation 1, 24, 48 and 72 hours after treatment and scored according to the Draize scoring system. Examination of the eye was facilitated by the use of the light source from a standard ophthalmoscope.
No corneal or iridial effects were noted. Moderate conjunctival irritation was noted in all three treated eyes one hour after treatment. Minimal conjunctival irritation was noted in all three treated eyes the 24-hour observation and persisted in one treated eye at the 48-hour observation. Two treated eyes appeared normal at the 48-hour observation and the remaining treated eye appeared normal at the 72-hour observation. Overall, the study authors concluded the test material to be a mild ocular irritant, based on a modified Kay and Calendra classification system, but using the CLP Regulation criteria no classification for eye irrritation is required.
