SCORING SYSTEM:
TOOL USED TO ASSESS SCORE: hand-slit lamp / biomicroscope / fluorescein
Using a Mini-Maglite® flashlight equipped with a high intensity bulb, the treated eye of each rabbit was examined for irritation of the cornea, iris and conjunctiva at 1, 24, 48 and 72 hours postdose and on day 7. Sodium fluorescein dye procedures were used at the 24, 48 and 72 hour observation interval, and again on day 7 in the initial animal, and at the 24 hour observation period in the two additional animals. The eye was examined with the aid of an ultraviolet light source. Ocular reactions were graded according to the numerical Draize technique.
Body weights were recorded pretest.
The general health of the animals was monitored at each observation time. All animals were humanely sacrificed using CO2 following study termination.

- Ocular findings (Table 1)
There was no corneal opacity noted at any observation period although fluorescein stain retention was noted in one eye. Iritis was noted in one eye at 24 hours and cleared by 48 hours. Conjunctival irritation, noted in 3/3 eyes, cleared by day 7.
Mean scores, following grading at 24, 48, and 72 h:
Corneal opacity: No animal has corneal opacity. The mean score (following grading at 24, 48, and 72 h) = (0+0+0)/3 = 0.
Iritis: 1 animal has Iritis at 24h and cleared by 48h. The mean score (following grading at 24, 48, and 72 h) = (1+0+0)/3=0.33. The score is <1.
Conjunctival redness: 3 animals have conjunctival redness. The mean score score (following grading at 24, 48, and 72 h) for animal 1 is (1+1+1)/3 = 1. Similar for animals 2 and 3. All scores are < 2.
Conjunctival chemosis: 3 animals have conjunctival chemosis. The mean score (following grading at 24, 48, and 72 h) for animal 1 is (2+2+2)/3 = 2. The mean score for animal 2 is (2+1+1)/3 = 1.67. The mean score for animal 3 is (2+1+1)/3 = 1.67. 1/3 score is 2. 2/3 scores are <2. - Other effects:
- Systemic Observations (Table 1)
There were no abnormal physical signs noted during the observation period.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- N-(4-(methoxybenzyl))-N,N-dimethylanilinium hexafluoroantimonate is an ocular irritant but not corrosive.
- Executive summary:
There was no corneal opacity noted at any observation period although fluorescein stain retention was noted in one eye. Iritis was noted in one eye at 24 hours and cleared by 48 hours. Conjunctival irritation, noted in 3/3 eyes, cleared by day 7. There were no abnormal physical signs noted during the observation period.
Based on GHS/CLP, substances that produce in at least 2 of 3 tested animals a positive response of: corneal opacity ≥ 1; and/or iritis ≥ 1; and/ or conjunctival edema ≥ 2; and/or conjunctival chemosis ≥ 2, calculated as the mean scores, following grading at 24, 48, and 72 h and which fully reverses within 21 day shall be classified in Category 2. In only one animal, one of the above responses was observed and thus the substance does not meet the classification criteria.
N-(4-(methoxybenzyl))-N,N-dimethylanilinium hexafluoroantirronate is an ocular irritant but not corrosive. However, it does not meet the GHS/CLP criteria for classification.
