TOOL USED TO ASSESS SCORE:
lmmediately after the 24-hour observation, a solution of 2% fluorescein in water (adjusted to pH 7.0) was instilled into both eyes of each animal to quantitatively determine corneal epithelial
damage. Any bright green stained area, indicating epithelial damage, was estimated as a percentage of the total corneal area.
OBSERVATIONS:
- Mortality/Viability: twice daily
- Toxicity: at least once daily
- Body Weight: day of treatment (prior to application) and at termination

- Irritant / corrosive response data:
- Instillation of approximately 42 mg of the test substance (a volume of approximately 0.1 mL) into one eye of each of three rabbits resulted in irritation of the conjunctivae, which was seen as
redness, chemosis and discharge. The irritation had completely resolved within 48 hours in one animal and in 72 hours in the other animals.
No iridial irritation or corneal opacity was observed, and treatment of the eyes with 2% fluorescein, 24 hours after test substance instillation revealed no corneal epithelial damage in any of the animals.
There was no evidence of ocular corrosion.
No staining of (peri) ocular tissues by the test substance was observed.
Remnants of the test substance were present in the eyes of all animals on day 1. - Other effects:
- - Lesions and clinical observations: no symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance is not irritating to the eyes.
According to Regulation (EC) No 1272/2008 and subsequent adaptations, the substance does not require classification as eye irritant.
