- STUDY DESIGN
The study was performed in a stepwise manner and was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner three weeks later, after considering the degree of eye irritation observed in the first animal.
TREATMENT
Animals were treated by instillation of, on average, 51.8 mg (range 51.6 – 52.2 mg) of the test substance (a volume of approximately 0.1 mL), in the conjunctival sac of one of the eyes 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 other eye remained untreated and served as the reference control.
Immediately after the 24-hour observation, a solution of 2% fluorescein (Merck, Darmstadt, Germany) 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.
Immediately after fluorescein examination on Day 2, the treated eye of the two other animals (an no. 253 and 260) was rinsed with approx 50 mL tepid tap water, using a velocity of flow which did not affect the eye, to remove residual test substance. For reference control the other eye was also rinsed.
REMOVAL OF TEST SUBSTANCE
-Washing (if done): yes, of the last two animals at 24 hours
OBSERVATIONS
- Mortality/Viability: Twice daily.
- Toxicity: At least once daily.
- Body Weight: Day of treatment (prior to instillation) and after the final observation.
- Necropsy: No necropsy was performed according to protocol.
- Irritation:
The eyes of each animal were examined approximately 1, 24, 48 and 72 hours and 7 days after instillation of the test
substance.
The irritation scores and a description of all other (local) effects were recorded.The irritation was assessed according to the
numerical scoring system as presented in OECD 405.

- Irritant / corrosive response data:
- Instillation of approximately 52 mg of HK 128 (a volume of approximately 0.1 mL) into one eye of each of three rabbits resulted in irritation of the conjunctivae, which consisted of redness, chemosis and discharge. The irritation had completely resolved within 48 hours in two animals and within 7 days in the other animal.
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. - Other effects:
- No staining of (peri) ocular tissues by the test substance was observed. Remnants of the test substance were present in the eye and/or on the outside of the eyelids on Day 1 and/or 2.
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:
- Based on these results, HK 128 does not have to be classified and has no obligatory labelling requirement for eye irritation according to the:
- Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011),
- Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures.
