(No. 405, 24th February 1987) and E.C. (92/69/E.E.C., B5, 31st July 1992) guidelines. The study was conducted in compliance with the Principles of Good Laboratory Practice Regulations. Methods The study design was established according to available information on the test substance and the above guidelines. As no irritant effects were anticipated, a single dose of 0.1 ml of the test substance was instilled into the left conjunctival sac of three male New Zealand White rabbits. The right eye served as control. The test substance was used in its original form. The eyes were not rinsed after administration of the test substance. Ocular reactions were observed approximately one hour, 24, 48 and 72 hours after the administration and then daily until reversibility of the ocular reactions. The mean values of the scores recorded for each animal after 24, 48 and 72 hours were calculated. Results Very slight to moderate conjunctival reactions were noted in all animals: very slight to moderate chemosis, very slight to moderate conjunctival redness and clear to whitish purulent discharge were observed from day 1 up to day 4 (one animal) or 6 (two animals). Slight iritis was observed on day 2 in two animals; it persisted for 24 hours in one of them. Very slight corneal opacity was also noted in all animals on day 2; it persisted up to day 4. Reversibility of ocular lesions was noted on day 5-(one animal) or 7. The mean scores calculated for each animal over 24, 48 and 72 hours were 1.3, 2.0 and 2.0 for chemosis, 2.0, 2.3 and 2.3 for redness of the conjunctiva, 0.7, 0.0 and 0.3 for iris lesions and 1.0, 1.0 and 1.0 for corneal opacity. .

INTRODUCTION The objective of this study was to evaluate the potential of the test substanc to induce ocular irritation following a single administration in rabbits. In the assessment of the toxic characteristics of a test substance, determination of the irritant effects on the eyes of mammals is an important initial step. Information derived from this test serves to indicate the possible existence of hazards to Man likely to arise from exposure of the eyes, and associated mucous membranes, to the test substance. This study was conducted in compliance with: . O.E.C.D. guideline No. 405,24th February 1987. . E.C. Directive No. 92/69/E.E.C., B5, 31st July 1992. 2. MATERIALS AND METHODS 2.1. TEST SUBSTANCE 2.1.1 Identification________ ' The test substance m i H ^ f l F u s e d in the study was supplied by Elf Atochem S.A. Documentation supplied by the Sponsor identified the test substance as follows: . name: . - protocol and labelling: ; . batch number: - protocol and labelling: < . Elf Atochem filing number: . description: dark brown liquid . container: one plastic flask . date of receipt: 11 October 1996 . storage conditions: at room temperature and protected from light. Data relating to the characterization of the test substance are documented in a test article description (presented in appendix 1) provided by the Sponsor! At the beginning of the study, the analytical certificate was not available. The pH of the test substance as mentioned in the safety data sheet was 8.5. 2.1.2 Preparation The test substance was used in its original form. ^ , Sa,,,lfeM. D o esn o lw n iaii)T sM cB | 2 2 . TEST SYSTEM 2.2.1 Animals Sex, species, strain: male New Zealand White rabbits. Reason for this choice: species commonly requested by the international regulations for this type of study. Breeder: Elevage Cunicole de Val de Selle, 80160 Prouzel, France. Number of animals and identification: three animals were used, as recommended by the international regulations and taking into account that a good correlation of results can be obtained with either three or six animals (i). The animals were identified individually with a metal tag in the ear. Weight: on the day of treatment, the animals had a mean body weight standard deviation of 2.4 0.2 kg. , Acclimatization: at least five days before the beginning of the study. 2.2.2 Environmental conditions During the acclimatization period and during the main test, the environmental conditions in the animal room were set as follows: . temperature: 183C . relative humidity: 30 to 70% . light/dark cycle: 12 h/12 h . ventilation: approximately 12 cycles/hour of filtered, non-recycled air. The temperature and relative humidity were recorded continuously and records retained The housing conditions (temperature, relative humidity and ventilation) were checked monthly. The animals were housed individually in polystyrene cages (35 cm x 55 cm x 32 cm or . cm x 58 cm x 36.5 cm). Each cage was equipped with a food container and a water bottle. 2.2.3 Food and water All the animals had free access to 112 C pelleted diet (U.A.R., 91360 Villemoisson-sur-Ore, r ranee). Each batch of food was analysed (composition and contaminants) by the supplier ' The diet formula is presented in appendix 2. Drinking water filtered by a F.G. Millipore membrane (0.22 micron) was provided ad libitum Bacteriological and chemical analysis of the water and diet and detection of possible contaminants (pesticides, heavy metals and nitrosamines) are performed periodically Results are archived at C.I.T. ' It was verified that no contaminants in the diet or water at levels-likely to influence the outcome ot the study were present. * (1) Jalsma, D.M.; Leach, C.L.; Hatoum, N.S.; Gibbons, R.D.; Roger, J.C.; Garvin, J.P.: Reducmg the number of rabbits in the Draize eye irritancy test: A statistical analysis 146-15?(198S8)COndUCted Ver 6 yearS' Fundamental and Applied Toxicology.

TREATMENT 2.3.1 Selection of the animals The day before treatment, the eyes of each animal were examined in order to use only animals without any signs of ocular irritation. Animals showing signs of ocular irritation, ocular defects or pre-existing corneal injury were not used. 2.3.2 Study design The study design was established according to available information on the test substance and according to the O.E.C.D. and E.C. guidelines. As no irritant effects were anticipated, the test substance was evaluated in three animals. ' 2.3.3 Administration of the test substance The test substance was used in its original form. A single dose of 0.1 ml of the test substance was instilled into the conjunctival sac of the left eye after gently pulling the lower lid away from the eyeball. The lower and upper eyelids were held together for about one second to avoid any loss of test substance. The right eye, which remained untreated, served as a control. The eyes were not rinsed after administration of the test substance. 2.3.4 Date of treatment Animal number 01 02 03 Date of treatment (day 1) 12 November 1996 12 November 1996 12 November 1996 End of the observation period 16 November 1996 18 November 1996 18 November 1996 2.4. OCULAR EXAMINATIONS The eyes were examined approximately one hour, 24, 48 and 72 hours after administration of the test substance. Following the O.E.C.D. and E.C. guidelines: . when there is no evidence of irritation after 72 hours, the study is ended. . when there is persistent ocular irritation after 72 hours, the observation period is extended to a maximum of 21 days (until day 22) in order to determine the progress of the lesions and their reversibility. . when severe irritant effects are observed, the animals are killed on humane ground. Any change in the animals' behaviour was noted. Com pany Sanitized. Does not contain T S C A C B E 11 2.5.

INTERPRETATION OF RESULTS AND CLASSIFICATION OF SUBSTANCES The results obtained were evaluated in conjunction with the nature and the reversibility of the scores observed, whilst taking into account all the reactions of the treated animals. 2.6.1 Interpretation of the results Criteria for irritation A substance or a preparation is considered irritant for the eyes if, when applied to the eye of the animal, significant severe ocular lesions are caused within 72 hours after exposure and which persist for 24 hours or more after treatment with the test substance. All the scores at each reading time (24, 48 and 72 hours) and for an effect are used by calculating the respective mean values. 2.6.2 Classification of the test substances - Xi symbol, indication of danger "irritant", - phrases indicating the nature of special risks: R 36: "Irritating to eyes" Ocular lesions are significant if the mean score has any of the following values: . opacity of the cornea > 2, but < 3, . lesion of the iris > 1, but < 1.5, . redness of the conjunctivae > 2.5, . oedema of the conjunctivae (chemosis) > 2. Or else, if the test is performed on three animals, if at least two of them show lesions equal to one of the following values: . opacity of the cornea > 2, but < 3, . lesion of the iris > 1, but < 2, - . redness of the conjunctivae > 2.5, . oedema of the conjunctivae (chemosis) > 2. R 41: "Risk of serious damage to eyes" Ocular lesions are severe: if the mean score has any of the following values: . opacity of the cornea >3, . lesion of the iris > 1.5. Or else, if the test is performed on three animals, if at least two of them show lesions equal to one of the following values: ' . opacity of the cornea > 3, . lesion of the iris = 2. p e H p s a y Sanitized.
