(No. 401, 24th February 1987) and E.C. (92/69/E.E.C, B,, 31st July 1992) guidelines. The study was conducted in compliance with the Principles of Good Laboratory Practice Regulations. Methods The test substance was administered by oral route to one group of ten fasted Sprague-Dawley rats (five males and five females). The test substance was administered in its original form, by gavage, at a dose of 2000 mg/kg, taking into consideration that its density was 1.07. Clinical signs, mortality and body weight gain were checked for a period of 14 days following the single administration of the test substance. All animals were subjected to necropsy. Results The general behaviour and body weight gain of the animals were not affected by treatment with the test substance. No death occurred at 2000 mg/kg. No abnormalities were observed at necropsy. Conclusion Undfir^ur^xperimental conditions, the oral LDg of the test substani ^UI^B^aass higher than or equal to 2000 mg/kg in rats. No sign;s of toxicity were observed at this dose. '^H RESUME Cm^H^^^HHIHB ade de Elf Atochem S.A., Paris-la-Defense, France, la toxicite aigue du produit a ete evaluee par voie orale chez Ie Rat confonnement aux lignes directricesdeTc^TOr(No. 401, 24th February 1987) et de la C.E.E.

INTRODUCTION The objective of this study was to evaluate the toxicity of the test substance following a single oral administration in rats. In the assessment of the toxic characteristics of a test substance, determination of acute oral toxicity is an initial step. It provides information on health hazards likely to arise from a short- term exposure by the oral route in Man. The study was conducted in compliance with: . O.E.C.D. guideline No. 401,24th February 1987. . E.C. Directive No. 92/69/E.E.C.. B], 31st July 1992. 2. MATERIALS AND METHODS 2.1. TEST SUBSTANCE 2.1.1 Identification The test substance^UUBJ used in the study was supplied by Elf Atochem S.A. Documentation supplied by the Sponsor identified the test substance as follows: . name: ____^^^^^ . batch number: ~^^^^^-"" i^i^ber^^^UHb . Elf Atochem filing . 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. 2.1.2 Preparation The test substance was administered in its original form. ^ ?9mpaRySamizefiL Daes Wt eoMaTri TeB GBF t/^S^^ft 2.2. TEST SYSTEM 2.2.1 Animals Species, strain: rat, Sprague-Dawley ICO: OFA-SD (IOPS Caw). Reason for this choice: rodent species commonly requested by the international this type of study. Breeder: Iffa Credo, 69210 L'Arbresle, France. Number and sex: one group of ten animals (five males and five females). Age/weight: on the day of treatment, the animals were approximately six weeks mean body weight standard deviation of 175 4 g for the males and 142 regulations for old, and had a 5 g for the females. Acclimatization: at least five days before the beginning of the study. Identification of the animals: the animals were identified individually by earmarks or ear-notches. 2.2.2 Environmental conditions During the acclimatization period and during the main test, the conditions in the animal room were as follows: . temperature: 21 2C . 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 in polycarbonate cages (48 cm x 27 cm x 20 cm). Each cage contained four to seven animals of the same sex during the acclimatization period and five rats of the same sex during the treatment period. Each cage contained dust-free sawdust (SICSA, 94142 Alfortville, France). Bacteriological analysis of the sawdust and detection of possible contaminants (pesticides, heavy metals) are performed periodically. 2.2.3 Food and water All the animals had free access to A04 C pelleted diet (U.A.R., 91360 Villemoisson-sur-Orge, France), except as noted in "2.3.1 Fasting of the animals". .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 of the study were present.

TREATMENT As the test substance was anticipated to be non-toxic at 2000 ing/kg, a limit test was performed by administering 2000 mg/kg of the test substance to one group of ten animals (five males and five females). 2.3.1 Fasting of the animals The animals were fasted for an overnight period of approximately 18 hours before dosing, but had free access to water. Food was given back approximately 4 hours after administration of the test substance. 2.3.2 Administration of the test substance The test substance was administered in its original form, taking into consideration that its density was 1.07. The administration was performed in a single dose by oral route using a stainless steel roundtipped probe (diameter: 18 G.2", Perfektum: Poffer & Sons Inc., New Hyde Park, New York 11040, U.S.A.) fitted to a 1 ml glass syringe (0.01 ml graduations. Record: Carrieri, 75005 Paris, France). The volume administered to each animal was adjusted according to body weight determined on the day of treatment. 2.3.3 Date of treatment and duration of the study The single administration was performed on 5 November 1996 in the morning (day 1) and was followed by a 14-day observation period until 19 November 1996 (day 15). 2.4. CLINICAL EXAMINATIONS The single administration was performed in the morning of day 1; it was followed by a 14-day observation period until day 15. 2.4.1 Clinical signs and mortality The animals were observed frequently during the hours following administration of the test substance, for detection of possible treatment-related clinical signs. Thereafter, observation of the animals was made at least once a day. Type, time of onset and duration of clinical signs were recorded for each animal individually. Time of death was recorded individually, in terms of the number of hours or days after dosing. 2.4.2 Body weight The animals were weighed individually just before administration of the test substance on day 1 and then on days 8 and 15. The body weight gain of the treated animals was compared to a reference curve ofC.l.T. control animals with the same initial body weight. .Company SanFltzed. Does not contain TSCA Cf 11 2.5. NECROPSY On day 15, all animals were killed by CO^ inhalation in excess and a macroscopic examination was performed. After opening the thoracic and abdominal cavities, a macroscopic examination of the main organs (digestive tract, heart, kidneys, liver, lungs, pancreas, spleen and any other organs with obvious abnormalities) was performed. In case of macroscopic lesions, organ samples were taken and preserved in 10% buffered formalin. No microscopic examination was performed. 2.6. DATA EVALUATION Evaluation of the toxicity of the test substance following a single oral administration in rats should include the relationship, if any, between the animals' exposure to the test substance and the incidence and severity of all abnormalities including behavioural and clinical abnormalities, macroscopic lesions, body weight changes, mortality and any other toxic effects. 2.7. ARCHIVES The study documentation and materials, namely: . protocol and possible amendments, . raw data, . correspondence, . final report and possible amendments, are stored in the archives of C.I.T., Miserey, 27005 Evreux, France, for five years after the end of the in viva phase of the study. At .the end of this period, the study documentation will be returned to the Sponsor. company Sar'.^lsec?-' D'^ss no? CWfatrt TSCT ' ^ 12 3. RESULTS 3.1. CLINICAL EXAMINATIONS 3.1.1 Clinical signs (table 1) No clinical signs were observed during the study. 3.1.2 Mortality (table 1) No death occurred during the observation period. 3.1.3 Body weight (treated animals: figure 1, table 2) (historical control animals: figure 2, table 3) The body weight gain of the animals was not influenced by treatment. 3.2. PATHOLOGY (table 4) Macroscopic examination of the main organs of the animals revealed no apparent abnormalities. 4.
