Applicant's summary and conclusion
- Interpretation of results:
- highly irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: other: Regulation EC n°1272/2008
- Conclusions:
- The test item, Reaction mass of sodium sulfate, sodium amino-12-dodecanoate and sodium dodecanoedioate, (batch No. T710/712) was severely
irritant when administered by ocular route to rabbits. - Executive summary:
The objective of this study was to evaluate the potential of the test item, Reaction mass of sodium sulfate, sodium amino-12-dodecanoate and sodium dodecanoedioate, to induce irritation following a single ocular administration in rabbitsaccording to OECD (No. 405, 24th April 2002) andCommission Regulation (EC) (No. 440/2008, B.5, 30 May 2008)guidelines.
The study was conducted in compliance with the principles of Good Laboratory Practice Regulations.
Methods
The test item, Reaction mass of sodium sulfate, sodium amino-12-dodecanoate and sodium dodecanoedioate, was first administered to a single male New Zealand White rabbit.
Since the test item was irritant on this first animal, it was then evaluated in sequential manneron two other animals.
The quantity of the test item administered was 0.1 mL.
For animal Nos. 514 and 522, a local anaesthetic was used prior to treatment.
The test item was introducedinto the conjunctival sac of the left eye. The right eye, which remained untreated, served as control.
The eyes were not rinsed after administration of the test item.
Ocular reactions were observed approximately 1 hour, 24, 48 and 72 hours after the administration and then daily until the reversibility of the ocular reactions (day 14; one animal) or the end of the observation period (two animals).
Body weight was recorded at the beginning and the end of the observation period. On completion of the observation period, the animals were sacrificed then discarded without macroscopicpost‑mortemexamination.
The mean values of the scores for chemosis, redness of the conjunctiva, iris lesions and corneal opacity were calculated for each animal.
The interpretation of results was carried out according to the classification criteria laid down in Council Directive 67/548/EEC (and subsequent adaptations).
Results
Slight to marked chemosis was noted in all animals from day 1 until day 13, 20 or 22.
Evaluation of redness of the conjunctiva was masked by a black eye discoloration in all animals on day 1 or from day 1 until day 2 or 13. Then slight to severe redness of the conjunctiva was noted until day 6, 12 or 20.
A clear discharge was noted in all animals, from day 2 until 3 or 4.
Evaluation of iris lesion was masked by a black eye discolorationin all animals on day 1 (two animals) or from day 1 until day 4 (one animal). Then, iris lesions were noted until day 5, 6 or 8. The evaluation of corneal opacity was masked by a black eye discoloration on day 1. Then, slight to marked corneal opacity, which covered the whole cornea in two animal during 2 or 4 consecutive days, was noted until day 7, 8 or 12.
Brownish area was noted in all animals from day 2 or 3 until day 6 (one animal) or 22 (two animals). Neovascularisation was observed on days 8 and 9 (one animal) from day 3 until day 6 (one animal) or on day 22 (one animal).
Mean scores calculated over 24, 48 and 72 hours were:
. for chemosis: 2.3, 3.0 and 3.0 for each animal,
. for corneal opacity: 3.0, 2.3 and 3.0 for each animal,
. for redness of the conjunctiva: 3.0 for animal No. 522,
. for the iris lesions: 1.0 for animals No. 514 and 522.
Due to eye discoloration, the mean scores were not calculable in the animals Nos. 524 and 514 for redness of the conjunctiva and in the animal No. 524 for the iris lesions.
Conclusion
The test item, Reaction mass of sodium sulfate, sodium amino-12-dodecanoate and sodium dodecanoedioate, was severely irritant when administered by ocular route to rabbits.
