- 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 7 days later, after considering the degree of skin irritation observed in the first animal.
TREATMENT
Approximately 24 hours before treatment, the dorsal fur was clipped with electric clippers, exposing an area of approximately 150 square centimeters (10x15 cm²). To facilitate scoring, treated skin areas were re-clipped at least 3 hours before the observations. Each animal was treated by dermal application of 0.5g of the test substance. The test substance was moistened with 1 mL of the vehicle and applied to the skin of one flank, using a metalline patch of 2x3 cm. The patch was mounted on Micropore tape, which was wrapped around the abdomen and secured with Coban elastic bandage. Four hours after the application, the dressing was removed and the skin cleaned of residual test substance using tap water, watery ethanol (50% v/v) (water; Milli-U, Millipore Corporation, Milli-U, Millipore Corporation, Bedford, USA; acetone, Labscan, Dublin, Ireland). For one animal the skin was also cleaned on day 2 with watery acetone (50% v/v) (tap water; acetone, Labscan, Dublin, Ireland). The treated skins were still stained by the test substance, but erythema could be assessed from 48 hours after application of the test substance onwards. After the final observation, the animals were sacrificed by intra-venous injection of pentobarbital (Euthesate®; Sanofi Sante B.V., Maassluis, The Netherlands).
OBSERVATIONS
Mortality/Viability: Twice daily; Toxicity: At least once daily; Body Weight: Day of treatment (prior to application) and at termination; Irritation: The skin reactions were assessed at approximately 1, 24,48 and 72 hours after the removal of the dressings and test substance. The irritation scores and a description of all other (local) effects were recorded. Adjacent areas of the untreated skin of each animal served as controls. - Irritation parameter:

- Details on study design:
- 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 7 days later, after considering the degree of eye irritation observed in the first animal.
TREATMENT:
Animals were treated by instillation of, on average, 34.4 mg (range 33.6 - 35.2 mg) of the test substance (a volume of approximately 0.1 mL), as the maximum required amount in the conjunctival sac of one of the eyes after gentiy pulling the lower lid away from the eyeball. The lids were then gentiy 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 one animal was rinsed with approx 50 mL tepid tap water, using a velocity of flow that did not affect the eye, to remove residual test substance. For reference control the other eye was also rinsed. After the final observation, the animals were sacrificed by intra-venous injection of pentobarbital (Euthesate; Sanofi Sante B.V., Maassluis, The Netheriands).
OBSERVATIONS:
Mortality/Viability: Twice daily; Toxicity: At least once daily; Body Weight: Day of treatment (prior to instillation) and at termination.

- Irritant / corrosive response data:
- Instillation of approximately 34 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 consisted of redness, chemosis and discharge. The irritation had completely resolved within 48 hours in two animals, and 72 hours in one 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. The observed mean values (24 - 72 h) of individual animals were 0.3, 0.3, 1.0 for redness and 0 in each case for chemosis, iritis and cornea opacity.
- Other effects:
- Colouration / Remnants: Remnants of the test substance were present in the eye on day 1 in two animals, and on days 1 and 2 in one animal. Red staining of the fur on the head and paws, caused by the test substance, was noted during the observation period.
Toxicity / Mortality: No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. - Interpretation of results:

Additional information
Skin irritation:
In a GLP-compliant primary skin irritation/corrosion study, performed according to OECD guideline 404, the test substance was tested on the skin of Albino New Zealand rabbits (Notox 2006). Three rabbits were exposed to 0.5g applied onto the clipped skin for 4 hours using a semi-occlusive dressing. Skin reactions were assessed 1, 24, 48 and 72 hours after exposure. No skin irritation was caused by 4 hours exposure. The observed mean values (24 - 72 h or 48 - 72 h) of individual animals for edema and erythema were 0 without exception. Orange staining of the treated skin by the test substance was observed throughout the observation period. This hampered the skin irritation assessment on day 1 and 2 only. Based on these results the test substance did not induce significant or irreversible damage to the rabbit skin and is considered not to be a skin irritant.
Eye irritation:
In a GLP-compliant acute eye irritation/corrosion study, tested according to OECD guideline 405, single samples of approximately 34 mg of test substance (a volume of approximately 0.1 mL) were instilled into one eye of each of three Albino New Zealand White rabbits (Notox 2006). Observations were made 1, 24, 48 and 72 hours after instillation. Instillation of the test substance 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 72 hours in one animal. The observed mean values (24 - 72 h) of individual animals were 0.3, 0.3,1.0 for redness and 0 in each case for chemosis, iritis and cornea opacity. Remnants of the test substance were present in the eye on day 1 in two animals, and on days 1 and 2 in one animal. Red staining of the fur on the head and paws, caused by the test substance, was noted during the observation period. Based on these results the test substance did not induce significant or irreversible damage to the rabbit eyes and is considered not to be an eye irritant.
Justification for classification or non-classification
