Test system

- Amount / concentration applied:
- 0.1 g of test substance (undiluted)
- Duration of treatment / exposure:
- single apllication to the conjunctival sac of the left eyelid
- Observation period (in vivo):
- 21 days
- Number of animals or in vitro replicates:
- 1 male and 2 females
- Details on study design:
- TREATMENT:
The eyes of the animals were examined for intactness once, one day prior to test substance administration.Only those animals with no signs of ocular injury or irritation were used on the test.At treatment, 0.1 g of the test article (undiluted) was placed in the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of the test substance. The right eye remained untreated and served as the reference control.
SCORING SYSTEM:

Swel 1 i ng wi th 1 i ds about hal f cl osed ...............................................................................................................3
Swelling with lids more than half closed ...................................................................................................................4
The maximum scores are:

- Irritant / corrosive response data:
- Reddening and swelling of the conjunctivae was evident in all animals, as was watery discharge. Hyperemia of the scleral blood vessels was noted in two animals. Reddening and swelling of the conjunctivae persisted in one animal until the end of observation, whereas reddening of the conjunctivae was noted ina second animal. Blue or light blue staining of the treated eyes by the test article was observed.No corrosion was observed at any of the measuring intervals.
- Other effects:
- The body weight of the animals was within the normal range of variability.
Applicant's summary and conclusion
- Interpretation of results:
- other: Irreversible effects on the eye (Category 1) according to the CLP Regulation
- Conclusions:
- The test substance produced irreversible effects on the eye.
- Executive summary:
The eye irritation test was performed to rabbit eye according to the OECD Guyideline 405.
The substance was found to cause irritation: in particular, the mean values at 24, 48 and 72 hours for not rinsed eyes were 0 for corneal opacity and iris in all animals, equal or higher than 2 for both conjunctival redness and chemosis, in two of three animals tested. In addition, the irritation symptoms were not fully reversible after 21 days of observation. Blue or light blue staining of the treated eyes by the test article was observed.
Therefore, the test substance can be classified in Category 1 due to irreversible effects on the eye, according to the CLP Regulation (EC n. 1272/2008).
