- Doses
Justification of the dose:
Starting dose was selected on the basis of the information provided by the Sponsor.
The LD50 value was expected to be above 2000 mg/kg bw. A limit test was performed at 2000 mg/kg bw dose.
Three female animals were treated with a dose level of 2000 mg/kg bw of Gelb Sulfato in the first step. - No. of animals per sex per dose:
- 6 animals all female, 3 animals/group
- Control animals:
- yes
- Details on study design:
- A single oral administration - followed by a fourteen-day observation period – was performed by gavage. On the day before each treatment the animals were fasted. The food but not water was withheld during an overnight period. Animals were weighed just before the treatment. The test item was administered by oral gavage in the morning hours. The food was given back 3 hours after the treatment. A constant treatment volume of 10 ml/kg body weight was applied.
Clinical Observations
Careful clinical observation was made 15 and 30 minutes, 1 h, 2 h, 3 h, 4 h, 6 h after the treatment and once each day for 14 days thereafter.
Individual observations were performed on the skin, fur, eyes, mucous membranes, respiratory, circulatory, autonomic and central nervous system, somatomotor activity and behaviour pattern as well. Particular attention was directed to the observation of tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma.
Body Weight Measurement
The body weight was recorded on day 0 (shortly before the treatment), then on days 7 and 14 with precision of 1g.
NECROPSY
Gross necropsy was performed in each experimental animal terminally. Animals were sacrificed by exsanguination under pentobarbital anaesthesia. After the examination of the external appearance the cranial, thoracic and the abdominal cavities were opened, the organs and the tissues were observed.
Abnormalities were recorded on post mortem data sheets. - Statistics:
- No data
Results and discussion
- Preliminary study:
- Three female animals were treated with a dose level of 2000 mg/kg bw of Gelb Sulfato in the first step. All animals survived; so three further animals were dosed at 2000 mg/kg bw dose level next day, as the second step. No mortality occurred in either steps, therefore the test was finished meeting the stopping criteria of guidelines (OECD 423, Directive 2004/73/EC B.1.tris, OPPTS 870.1100).

- Gross pathology:
- No macroscopic alterations related to the toxic effect of Gelb Sulfato were found at necropsy. Hydrometra (1/3, Group 1) is a common necropsy findings in experimental rats related to the sexual cycle of animals. The pinprick-sized haemorrhages (1/3 in Group 2) observed in the lungs were due to the exsanguination.
- Other findings:
- None

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral LD50 value of the test item Gelb Sulfato proved to be greater than 2000 mg/kg body weight in female CRL:(WI) BR rats.
- Executive summary:
An acute oral toxicity study was performed to assess the acute toxicity of test item Gelb Sulfato in rats. The results of the study allowed the test item to be ranked according to the classification systems, currently in use.
The acute toxic class method according to OECD 423 and Directive 2004/73/EC B.1. tris was performed with Gelb Sulfato. The study was performed in accordance with the Principles of Good Laboratory Practice (GLP) and reported with a GLP certificate.
Two groups of three female CRL:(WI) BR Wistar rats were treated by single oral gavage with Gelb Sulfato at dose levels of 2000 mg/kg bw in two independent experiments (Treatment group 1 and Treatment group 2). A concentration of 200 mg/ml prepared with distilled water corresponding to a treatment volume of 10 ml/kg bw was used at both steps.
Clinical observations were performed for all animals 15 and 30 minutes, 1, 2, 3, 4 and 6 hours after dosing and daily for 14 days thereafter. Food was made available again 3 hours after the treatment. Body weight was measured weekly. Gross necropsy was performed on all animals at termination of examination (day 14).
Results
Mortality:No mortality occurred after a single oral administration of Gelb Sulfato at 2000 mg/kg bw dose level in female CRL:(WI) BR rats.

Clinical symptoms:Slight activity decrease, hunched back and piloerection were noted for one animal (1/6) two hours after the treatment. There were no test item effect on the physical condition and behaviour of the remaining animals. Yellow coloured urine and faces were noted on the day of the treatment and on the next day.
Body weight and body weight gain:The mean body weight and the body weight gain of animals were in the normal range during the two weeks observation period, similar to the expected values in untreated animals of the same age and strain.
Necropsy
No macroscopic alterations related to the toxic effect of Gelb Sulfato were found
Conclusion:
The acute oral LD50value of the test item Gelb Sulfato was greater than 2000 mg/kg body weight in female CRL:(WI) BR rats.
Gelb Sulfato does not meet the requirements of EU labelling regulations.
