Test animals

Species:
rat
Strain:
Wistar
Sex:
male/female

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
corn oil
Details on oral exposure:
The vehicle was chosen after a non-GLP solubility trial which was performed before the study initiation date. Since the test item was not soluble in water, solubility trials were performed in PEG 300 and corn oil. The test item was not soluble in PEG 300, but corn oil was found to be a suitable vehicle.
This formulation trial is excluded from the statement of compliance.
Doses:
2000 mg/kg bw
No. of animals per sex per dose:

Control animals:
no
Details on study design:
Per step three females were used. For confirmation of the highest tolerated dose a group of three males was used due to
possibility of different responses in both sexes.
Statistics:
No statistical analysis was used.

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information EU DSD and Regulation (EC) No 1272/2008 Criteria used for interpretation of results: EU
Conclusions:
The median lethal dose of SAT 080004 after single oral administration to rats of both sexes, observed over a period of 14 days, is:
LD50 (rat): greater than 2000 mg/kg body weight.

Based upon the results of this study the following classifications are proposed:

• According to the Commission Directive 2001/59/EC of 06 August 2001 (Official Journal of the European Communities Nr. L 225/1, August 21,
2001), SAT 080004 does not have to be classified and labelled with respect to acute oral toxicity in the rat.

• According to the Regulation (EC) No 1272/2008 of the European Parliament and of the Council of 16 December 2008, SAT 080004 does not have to be classified and labelled with respect to acute oral toxicity in the rat.

• According to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), Second revised Edition, 2007, SAT 080004
should be classified asCategory 5.
Executive summary:

Two groups, each of three female or three male RccHan:WIST (SPF) rats, were treated with SAT 080004 by oral gavage administration at a dosage of 2000 mg/kg body weight. The test item was formulated in corn oil at a concentration of 0.2 g/mL and administered at a dosing volume of 10 mL/kg.

The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recorded. All animals were examined for clinical signs within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2-15. Mortality/viability was recorded within the first 30 minutes and approximately 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2-15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically.

All animals survived until the end of the observation period.

No clinical signs were observed during the course of the study in all three female animals. Slightly ruffled fur was observed in two males following the treatment on day 1 only.

The body weight of the animals was within the range commonly recorded for this strain and age.

No macroscopic findings were recorded at necropsy.

The median lethal dose of SAT 080004 after single oral administration to rats of both sexes, observed over a period of 14 days, is:

LD50 (rat): greater than 2000 mg/kg body weight
