CORNEA
Opacity: degree of density (area most dense taken for reading)
No ulceration or opacity 0
Scattered or diffuse areas of opacity (other than slight dulling of normal luster), details of iris clearly visible 1
Easily discernible translucent area, details of iris slightly obscured 2
Nacreous area, no details of iris visible, size of pupil barely discernible 3
Opaque cornea, iris not discernible through the opacity 4
IRIS
Normal 0
Markedly deepened rugae, congestion, swelling, moderate circumcorneal hyperemia, or injection, any of these or combination of any thereof, iris still reacting to light (sluggish reaction is positive) 1
No reaction to light, hemorrhage, gross destruction (any or all of these) 2
CONJUNCTIVAE
Redness (refers to most severe reading of palpebral and bulbar conjunctivae when compared with control eye)
Blood vessels normal 0
Some blood vessels definitely hyperemic (injected) 1
Diffuse, crimson color, individual vessels not easily discernible 2
Diffuse beefy red 3
CHEMOSIS: lids and/or nictitating membranes

- No clinical signs of systemic toxicity were observed and no mortality occurred. Red residues were observed at 1 h in all animals. No discoloration of the cornea and conjunctivae was observed.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- After dermal application of 0.5 g of the substance to rabbits for 4 h according to OECD 404 (1981) no erythema or edema were observed. Therefore, the test item is considered to be not irritating to rabbit skin.
- Executive summary:
In an eye irritation/corrosion GLP-compliant study according to guideline OECD 405, threee New Zealand White rabbits (15 -16 weeks old, approx. 2.5 kg) were exposed by applying 0.1 g of undiluted test article to the left eye of each animal. Eyes wre not rinsed and irritation was evaluated at 1, 24, 48 and 72h.
Since no effects were observed at 24, 48 and 72 hours after treatment, the substance was not irritating to the rabbit eye.
