- 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 one week later, after considering the degree of eye irritation observed in the first animal.
Preemptive pain management
One hour prior to instillation of the test substance, buprenorphine 0.01 mg/kg was administered by subcutaneous injection in order to provide a therapeutic level of systemic analgesia.
Five minutes prior to instillation of the test substance, two drops of the topical anesthetic alcaine 0.5% were applied to both eyes.
Treatment
Immediately after the 1 hour observation, the treated eyes of two animals (806 and 808) were rinsed with approx. 50 mL tepid tap water, using a velocity of flow which did not affect the eye, to remove any visible residual test substance. For reference control the other eye was also rinsed.
Immediately 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.
Immediately after fluorescein examination on Day 2, in order to provide a continued level of systemic analgesia, buprenorphine 0.01 mg/kg and meloxicam 0.5 mg/kg were administered by subcutaneous injection.
After the final observation, the animals were sacrificed by intra-venous injection of Euthasol® 20%.
Observations
- Mortality/Viability: Twice daily.
- Toxicity: At least once daily.
- Body Weight: Day of treatment (prior to instillation) and after the final observation.
- Irritation: The eyes of each animal were examined approximately 1, 24, 48 and 72 hours after instillation of the test substance. The irritation scores and a description of all other (local) effects were recorded.

- Irritant / corrosive response data:
- Instillation of approximately 58 mg of test substance (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 one animal and in 72 hours in the other two animals.
No iridial irritation or corneal opacity were observed, and treatment of the eyes with 2% fluorescein 24 hours after test substance instillation revealed no corneal epithelial damage.
There was no evidence of ocular corrosion.
Remnants of the test substance were present in the eye on Day 1. - Other effects:

Additional information
Skin irritation/corrosion
Two studies are available:
1) An acute dermal irritation study was conducted according to OECD 404 using rabbits (Latour, 2014). Key study.
This study showed that the test substance is not irritating.
2) An in vitro skin corrosion study was conducted according to OECD 431 using a human skin model (Buskens, 2014). Supporting study.
In the interest of animal welfare and to minimize any testing likely to produce severe responses in animals, a human skin model test was performed. This study showed that the test substance is not corrosive. Based on this, in vivo skin irritation study in rabbit was performed to establish the possible skin irritating properties of the test substance.
Eye irritation
Two studies are available:
1) An acute eye irritation study was conducted according to OECD 405 using rabbits (Latour, 2014). Key study.
This study showed that the test substance is slightly irritating.
2) An in vitro BCOP study was conducted according to OECD 437 using bovine cornea (Verspeek-Rip, 2014). Supporting study.
In the interest of animal welfare and to minimize any testing likely to produce severe responses in animals, an in vitro BCOP test was performed. This study showed that the test substance is not irritating. Based on this, in vivo eye irritation study in rabbit was performed to establish the possible eye irritating properties of the test substance.
Justification for selection of skin irritation / corrosion endpoint:
This in-vivo study was conducted according to OECD 404 using rabbits.
Justification for selection of eye irritation endpoint:
This in-vivo study was conducted according to OECD 405 using rabbits.
Effects on eye irritation: slightly irritating
Justification for classification or non-classification
Skin irritation/corrosion: Mean scores at 24, 48 & 72 hours for erythema were < 2.3 (actual value 0) for oedema were < 2.3 (actual value 0). In addition all reactions were fully reversible within the observation period.
Serious eye damage/eye irritation: Mean scores at 24, 48 & 72 hours for corneal opacity were < 1 (actual value 0), for iritis were < 1 (actual value 0), for conjunctival redness were < 2 (actual value 0.56) and for conjunctival oedema were < 1 (actual value 0).
Therefore in accordance with Regulation (EC) No. 1272/2008 Tables 3.2.2 & 3.3.2 the substance is not classified for the skin corrosion/irritation and serious eye damage/eye irritation endpoint.
