SCORING SYSTEM:
Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment, according to the numerical evaluation from Draize J H (1977, "Dermal and Eye Toxicity Tests" In: Principles and Procedures for Evaluating the Toxicity of Household Substances, National Academy of Sciences, Washington DC p.48 to 49.
TOOL USED TO ASSESS SCORE:
Examination of the eye was facilitated by the use of the light source from a standard ophthalmoscope.

- Irritant / corrosive response data:
- Dulling of the normal lustre of the cornea was noted in the treated eye one hour after treatment. Scattered or diffuse corneal opacity was noted at the treated eye at the 24-hour observation with translucent corneal opacity at the 48, 72-hour, 7 and 14-day observations. Scattered or diffuse corneal opacity was noted in the treated eye at the 21-day observation.
Iridial inflammation was noted in the treated eye one hour after treatment and at the 24, 48, 72-hour and 7-day observations.
Moderate conjunctival irritation was noted in the treated eye one hour after treatment and at the 24, 48, 72-hour, 7 and 14-day observations.
Vascularisation, with a generalised ingrowth of vessels for approximately 3 to 4 mm, was noted in the treated eye at the 7, 14 and 21-day observations with ectropion also noted in the treated eye at the 14-day observation.
The reactions noted at the 21-day observation were considered to be irreversible.
The test material produced irreversible effects and was considered to be CORROSIVE to the rabbit eye.
The test material was also considered to be irritant according to EU labelling regulations Commission Directive 93/21/EEC. It is reasonable to assume that the symbol "Xi", the indication of danger "Irritant" and the highest risk phrase R 41 "RISK OF SERIOUS DAMAGE TO EYES" are therefore required. - Other effects:

Interpretation of Results
The numerical values corresponding to each animal, tissue and observation time were recorded. The data relating to the conjunctivae were designated by the letters A (redness), B (chemosis) and C (discharge), those relating to the iris designated by the letter D and those relating to the cornea by the letters E (degree of opacity) and F (area of cornea involved). For each tissue the score was calculated as follows:
Score for
conjunctivae = (A + B + C) x 2
Score for iris = D x 5
Score for cornea = (E x F) x 5
Using the numerical data obtained a modified version of the system ( Modified Kay and Calandra Interpretation of Eye Irritation Test was used to classify the ocular irritancy potential of the test material. This was achieved by adding together the scores for the cornea, iris and conjunctivae for each time point for each rabbit. The group means of the total scores for each observation were calculated. The highest of these group means (the maximum group mean score) together with the persistence of the reactions enabled classification of the eye irritancy potential of the test material.
If evidence of irreversible ocular damage is noted, the test material will be classified as corrosive to the eye.
Applicant's summary and conclusion
- Interpretation of results:
- corrosive
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test material produced irreversible effects and was considered to be CORROSIVE to the rabbit eye.
- Executive summary:
Introduction. The study was performed to assess the irritancy potential of the test material to the eye of the New Zealand White rabbit. The method was designed to meet the requirements of the following:
-OECD Guidelines for the Testing of Chemicals No. 405 "Acute Eye Irritation/Corrosion" (adopted 24 February 1987)
-Commission Directive 92/69/EEC Method B5 Acute Toxicity (Eye Irritation)
Result. A single application of the test material to the non-irrigated eye of one rabbit produced irreversible effects. Reactions noted included translucent corneal opacity, iridial inflammation, moderate conjunctival irritation, dulling of the normal lustre of the cornea, ectropion and vascularisation with a generalised ingrowth of vessels for approximately 3 to 4 mm.
Conclusion. The test material produced irreversible effects and was considered to be corrosive to the rabbit eye.
The test material was also considered to be irritant according to EU labelling regulations Commission Directive 93/21/EEC. It is reasonable to assume that the symbol "Xi", the indication of danger "Irritant" and the highest risk phrase R 41 "RISK OF SERIOUS DAMAGE TO EYES" are therefore required. Under the GHS it is classified under the health hazard category "Eye Damge 1" with a hazard statement H318: Causes serious eye damage.
