- Irritant / corrosive response data:
- Instillation of approximately 98 mg of the test substance 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 72 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:
- Remnants of the test substance were present in the eye of two animals on Day 1.
- Interpretation of results:
- slightly irritating

Additional information
Skin irritation/corrosion
Two studies are available:
1) A primary 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 acute eye irritation study was conducted according to OECD 405 using rabbits (Beerens - Heijnen, 2010). 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, 2010). 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:
Study run to a method comparable with current guidelines and to GLP
Justification for selection of eye irritation endpoint:
Study run to a method comparable with current guidelines and to GLP
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 (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 0.89) and for conjunctival oedema were < 1 (actual value 0.67).
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.
