Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: other: CLP (Reg. 1272/2008/EC) and Directive 67/548/EEC

Conclusions:

Under these experimental conditions, the tested substance Genamin SH 301 is not classified according to CLP (Reg. n° 1272/2008/EC) and directive 67/548/EEC.

Executive summary:

The objective of this study was to evaluate the toxicity of Genamin SH 301 following a single oral administration in rats according to the OECD guideline 401 and to the EU Method B.1. The study was conducted in compliance with the principles of Good Laboratory Practice regulations.

Genamin SH 301 was prepared in sesame oil and was administered by gavage under a dosage-volume of 10 ml/kg bw to 2 groups of 5 male and 5 female rats.

Based on a preliminary study indicating no deaths in 1 male and 1 female rats at 2000 mg/kg bw, the main experiment was performed at the limit dose level of 2000 mg/kg bw.

Clinical signs, mortality and body weight were checked for a period of 14 days following the single administration of the test item. All animals were subjected to necropsy.

At the dose-level of 2000 mg/kg, no mortality, no clinical signs and no effects on body weight gain were observed. There were no apparent abnormalities at necropsy.

Under these experimental conditions, the oral LD0 of Genamin SH 301 was equal or higher than 2000 mg/kg bw in rats.
