- OBSERVATIONS
-Irritation: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.
-Viability / Mortality/ Toxicity: twice daily.
-Body Weight: once, on day of treatment (prior to instiUation).
-Staining of the treated eye was described and recorded at each observation. In case standard lighting was considered Inadequate for observing minor effects, eye examinations were performed using a pocket flash light. In cases of equivoca! results when comparing the treated and untreated eyes, the illustrated guide from the Consumer Product Safety Commission, Washington, D.C. 20207 was used for additional control purposes.

- Irritant / corrosive response data:
- -Irritation: slight dulling of normal lustre was also noted on day 1 in all animals, but had disappeared after 24 hours. Treatment of the eyes with 2% fluorescein revealed no corneal epithelial damage in any of the animals, and confirmed the absence of corneal injury after 24 hours. The irritation consisted of redness (maximum grades 1 -2) and chemosis (maximum grade 2) of the conjunctivae and lacrimation. However, conjunctival redness could not be scored on day 1 and was difficult to score at the following observations, due to black discolouration by the test substance. A small amount of discharge was also noted in animals #1 and #2 during the study.
-Corrosion: there was no evidence of ocular corrosion.
-Colouration: black staining of the conjunctival tissues and of the fur on the head and paws of the animals was noted throughout the observation period. - Interpretation of results:
- other: Classified for serious eye damage (Category 1) according to the CLP Regulation (EC 1272/2008)
- Conclusions:
- The test substance produced irreversible effects on the rabbit eye.
- Executive summary:
The eye irritation test was performed to the rabbit eye according to OECD Guidelines 405 (1987) and the method B.5 of EEC-Directive 92/69 EEC. The substance was found to cause in all animals slight dulling of normal lustre at 1 hour, disappeared after 24 hours. Treatment of the eyes with 2% fluorescein revealed no corneal epithelial damage in any of the animals, and confirmed the absence of corneal injury after 24 hours. Mean values at 24, 48 and 72 hours for iris and corneal opacity were 0 in all animals. The substance affected the conjunctivae: redness scores (mean values at 24, 48 and 72 hours ) were 0.67 for animal #1 and 1.33 for animals #2 and #3 and chemosis scores (mean values at 24, 48 and 72 hours ) were 1 for all animals. These effects on conjunctival redness and chemosis were reversible within 72 hours (animal #1) and 7 days (animals #2 and #3). However, conjunctival redness could not be scored on day of treatment and was difficult to score at all the following observations, due to black discolouration caused by the test substance. A black staining of the conjunctival tissues of all animals was noted throughout all the observation period and the reversibility could not be verified.

Additional information
SKIN IRRITATION
The skin irritation test was performed to rabbit skin according to the OECD Guideline 404 (1981) and the method B.4 of EEC-Directive 92/69 EEC. The test substance was found to be not irritant when applied to intact rabbit skin: local signs (mean values 24/48/72 hours) consisted of grade 0 erythema and grade 0 oedema. The test substance caused blue staining of the treated skin only on day of the application. No corrosive effects were noted on the treated skin of any animal at any measuring interval.
EYE IRRITATION
The eye irritation test was performed to the rabbit eye according to OECD Guidelines 405 (1987) and method B.5 of EEC-Directive 92/69 EEC. A slight dulling of normal lustre was observed in all animals at 1 hour, but it disappeared after 24 hours. Mean values 24/48/72 h for iris and corneal opacity were 0 in all animals. The substance affected the conjunctivae: redness scores (mean values 24/48/72 h) were 0.67 for animal #1 and 1.33 for animals #2 and #3; chemosis scores (mean values 24/48/72 h) were 1 for all animals. These effects on conjunctival redness and chemosis were considered reversible within 72 hours (animal #1) and 7 days (animals #2 and #3). However, conjunctival redness could not be scored on day of treatment and was difficult to score at all the following observations, due to black discolouration caused by the test substance. A black staining of the conjunctival tissues of all animals was noted throughout all the observation period and the reversibility could not be verified within the 7 day-period of the study.
Justification for classification or non-classification
In the CLP Regulation (EC 1272/2008), skin irritation is defined as "the production of reversible damage to the skin following the application of a test substance for up to 4 hours." A single irritant category (Category 2) is defined and, using the results of animal testing, the classification criteria are presented in Annex I: 3.2.2.7.1, Table 3.2.2.
Based on the results of Acute Dermal Irritation/Corrosion study conducted on the test substance, no classification for skin irritation is warranted under the CLP Regulation (EC 1272/2008).
Moreover the CLP Regulation (EC 1272/2008), defines Serious eye damage as “the production of tissue damage in the eye, or serious physical decay of vision, following application of a test substance to the anterior surface of the eye, which is not fully reversible within 21 days of application”. A substance that has the potential to seriously damage the eyes is classified in Category 1 (irreversible effects on the eye). On the basis of the results of animal testing, the classification criteria are presented in Annex I: 3.3.2.6.1., Table 3.3.1.
Based on the results of Acute Eye Irritation/Corrosion study conducted, the substance was found to cause a black staining of the conjunctival tissues of all animals throughout all the observation period and the reversibility could not be verified. Therefore, the test substance should be classified in Category 1 due to irreversible effects on the eye, according to the CLP Regulation (EC 1272/2008).
