Relative humidity during testing: 30-70%. Upper limit incidentally up to 100%, because of meteorological circumstances and/or wet cleaning of the animal room.
Ventilation: ca 10 air changes/hour
Diet/water: standard laboratory diet ad libitum. Each batch of this diet is analysed by the supplier (SDS Special Diets services, Whitham, England) for the nutrients and contaminants and the results are kept available in the archives. Tap water (N.V. Hydron MiddenNederland) ad libitum. Results of routine physical, chemical and microbiological examination of drinking water as conducted by the supplier are kept available in the archives. The results of diet and water analyses were considered acceptable for this study. - Route of administration:
- oral: gavage
- Vehicle:
- water
- Details on oral exposure:
- The animals were dosed with a 10 ml/kg body weight of a 200 mg/ml aqueous suspension of the test substance in order to obtain the 2000 mg/kg dose level.
- Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 6 animals
- Control animals:
- no
- Details on study design:
- The study was started with treatment of three females with a dose level of 2000 mg/kg body weight. Since none of the animals died during the following hours, the test was continued with the same dosing of another three females. The animals were dosed with a 10 ml/kg body weight of a 200 mg/ml aqueous suspension of the test substance in order to obtain the 2000 mg/kg dose level. The exact amount of the test substance to be dosed was calculated for each animal individually and administered by means of a syringe, equipped with an oral gavage. Prior to dosing, the animals had fasted overnight.
Approximately 4 hours after dosing, they had access to food again. The animals were observed for mortality up to 14 days after treatment.
Observation and measurements
Clinical signs: All visible reactions to treatment were recorded, including type, severity, onset and duration. Observations were made within 1 hour and within 4 hours after dosing, and subsequently in surviving animals at least once daily throughout an observation period of 14 days.
Body weights: The body weight of each animal was recorded immediately before dosing on day 0, and of the surviving animals on days 3, 7 and 14 of the study.
Termination of the study: At the end of the observation period, on day 14 of the study, all surviving animals were killed with carbon dioxide and examined for external changes. Next, the abdomen and the thorax of each animal was opened and examined for gross pathological changes. - Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality was observed during the 14-day study period.
- Clinical signs:
- other: No clinical signs was observed during the 14-day study period.
- Gross pathology:
- Examination at necropsy of the animals did not reveal distinct treatment-related gross alterations.
- Other findings:
- No further findings investigated in this study.
- Interpretation of results:
- not classified
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- Since all animals survived the 2000 mg/kg dose level, the oral LD50 of T-1063FM is considered to be higher than 2000 mg/kg body weight.

- Details on dermal exposure:
- At the end of the acclimatization period, the hair was removed from the back and flanks of the animals using electric clippers in a way as to avoid abrasions. The next day, the test material was applied to the clipped area of 5 male and 5 female rats by weight in one dose level of 2000 mg of the test substance per kg body weight. For this purpose, the animals were dosed with a 4 ml/kg body weight of a 500 mg/ml aqueous suspension of the test substance in order to obtain the 2000 mg/kg dose level. The weight variation of the animals did not exceed plus or minus 20% of the mean body weight at the start of the study. The amount of the test material was calculated for each animal individually and distributed in a thin layer over an area of intact skin, measuring at least 4 x 5 cm. For each animal, the exposure area was at least 20 cm2, i.e. at least 10% of the total body surface of the animals. The exposed area was covered by a gauze, which was fixed to the application site by means of adhesive tape and the entire trunk of the rat was wrapped with a tape to maintain the test patch in position and to retard evaporation of volatile substances. During the exposure period the animals were housed individually. After an exposure period of circa 24 hours the materials and residues of the material applied were removed with water. The animals were observed for mortality up to 14 days after treatment.
- Duration of exposure:

Dermal reactions: The skin reactions were evaluated by the method of Draize et al. (J. Pharmacol. Exp. Ther. 82 (1944) 377-390). Skin readings were made on day 1 after substance removal, and in surviving animals on days 3, 7, and 14 of the study.
Termination of the study: At the end of the observation period, on day 14 of the study, all surviving animals were killed with carbon dioxide and examined for external changes. Next, the abdomen and the thorax of each animal was opened and examined for gross pathological changes. - Sex:

Additional information
Justification for classification or non-classification
In both, the acute oral and the acute dermal toxicity studies, all animals survived the limit dose of 2000 mg/kg b.w. Therefore, classification of T-1063 FM for acute oral or dermal toxicity is not required according to REGULATION (EC) 1272/2008. Also classification for acute inhalation toxicity is not required based on the arguments as provided in the waiver of the respective study.
