Materials and methods
- Principles of method if other than guideline:
- BASF-Test:
The substance was injected into the peritoneal cavity. Young adult laboratory mice were purchased from breeder. Several groups of 5 mice per sex and dose were treated simultaneously with preparations of the test substance in suitable vehicle. The concentrations of these preparations were used to achieve comparable volumes per kg body weight. Group-wise documentation of clinical signs was performed over the 14 day study period. - GLP compliance:
- no
- Remarks:
- GLP was not compulsory at the time the study was conducted
- Limit test:
- no

Applicant's summary and conclusion
- Conclusions:
- Under the test conditions the LD50 after i.p. application in mice is approx. 120 mg/kg bw for males, approx. 100 mg/kg bw for females and approx. 100 mg/kg bw for males and females.
- Executive summary:
The study meets generally accepted scientific principles.
Groups of 5 mice per sex and dose were treated with preparations of the test substance in water. The substance was injected into the peritoneal cavity at 200, 100 and 68.1 mg/kg bw. The application volume was 10 ml/kg bw. A 14 -day observation period followed the application of the test substance.
At the highest dose tested all animals died within the first day. At 100 mg/kg 1 male and 3 females died one day after application. No mortalities occurred at 68.1 mg/kg. Signs of intoxication at 200 mg/kg were dyspnea, apathy, staggering, paresis of hind limb, trembling, ruffled fur and poor general state (4 - 5 h after application). At 100 mg/kg clinical signs were dyspnea, apathy, ruffled fur and poor general state (4 h - 1 d after application). At 68.1 mg/kg no signs of intoxication were observed. Gross pathologic findings of animals that died were at 100 mg/kg despite congestion individual greyish brown areas in the liver to be seen also on the cut surface. At 200 mg/kg no intraabdominal conglutinations or test substance deposits were found. In sacrificed animals organs were found to be normal.
Conclusions: Under the test conditions the LD50 after i.p. application in mice is approx. 120 mg/kg bw for males, approx. 100 mg/kg bw for females and approx. 100 mg/kg bw for males and females.
