- Number of animals or in vitro replicates:
- 3 males
- Details on 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, 66.9 mg (range 66.5 - 67.3 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 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.
After the final observation, the animals were sacrificed by intra-venous injection of Euthasol® 20%. - Irritation parameter:

Additional information
Skin irritation/corrosion
Two studies are available:
1) A skin irritation study was conducted according to OECD 404 using rabbits (Beerens - Heijnen, 2010). 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, 2010). 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 eye irritation study was conducted according to OECD 405 using rabbits (Beerens - Heijnen, 2010). Key study.
This study showed that the test substance is not irritating.
2) An eye irritation study was conducted according to OECD 437 using an isolated bovine (Verspeek-Rip, 2010). Supporting study.
In the interest of animal welfare and to minimize any testing likely to produce severe responses in animals, an in vitro Bovine Corneal Opacity and Permeability (BCOP) study was performed. This study showed that the test substance is not severe irritant or corrosive. 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 study was conducted according to OECD 404 under GLP.
Justification for selection of eye irritation endpoint:
This study was conducted according to OECD 405 under GLP.
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 (actual value within 72 hours).
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 1) and for conjunctival oedema were < 1 (actual value 0.3).
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.
