- Mortality:
- No mortality was observed.
- Clinical signs:
- other: No clinical signs related to test material were observed.
- Gross pathology:
- No abnormalities were noted at necropsy.
- Other findings:
- None
- Interpretation of results:
- not classified
- Remarks:

- Conclusions:
- Rat Oral LD50 Combined > 5000 mg/kg bw
- Executive summary:
In an acute oral toxicity study (limit test) performed similarly to OECD guideline 401, groups of rats (5/sex) were administered a single oral dose of test material at 5000 mg/kg bw by gavage. Animals were then observed for mortality, clinical signs and bodyweights for 14 days and at the end of the study the surviving animals were sacrificed for macroscopic examination.
No mortality or clinical signs were observed. All animals showed expected gains in bodyweight over the 14 day study period. No abnormalities were noted at necropsy.
Oral LD50 Combined > 5000 mg/kg bw
Under the test conditions, the test material is not classified according to the annex VI of the Regulation EC No. 1272/2008 (CLP).

Additional information
Acute toxicity: oral
A key study was identified on the registered substance (Biosearch, 1979) The study was non-GLP, but followed or was similar to OECD Test guideline No 401. In this study (limit test), groups of rats (5/sex) were administered a single oral dose of test material at 5000 mg/kg bw by gavage. Animals were observed for mortality, clinical signs and bodyweights for 14 days and at the end of the study the surviving animals were sacrificed for macroscopic examination.
No mortality or clinical signs were observed. All animals showed expected gains in bodyweight over the 14 day study period. No abnormalities were noted at necropsy.
Oral LD50 (rats) > 5000 mg/kg bw.
Justification for selection of acute toxicity – oral endpoint
Only one reliable study available
Justification for classification or non-classification
Harmonized classification:
The substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.
Self classification:
Acute toxicity via Oral route:
Based on the available data, the substance is not classified according to the Regulation (EC) No. 1272/2008 as the LD50 is greater than 5000 mg/kg bw
Acute toxicity via Dermal route:
No data was available.
Acute toxicity (Inhalation):
No data was available.
Specific target organ toxicity: single exposure (Oral):
The classification criteria according to the Annex VI of the Regulation (EC) No. 1272/2008 as specific target organ toxicant (STOT) – single exposure, oral are not met since no reversible or irreversible adverse health effects were observed immediately or delayed after exposure and no effects were observed at the guidance value (oral) for a Category 1 classification (C ≤ 300 mg/kg bw) and at the guidance value (oral) for a Category 2 classification (2000 mg/kg bw ≥ C > 300 mg/kg bw). No classification is required.
Specific target organ toxicity: single exposure (Dermal):
No data was available.
Specific target organ toxicity: single exposure (Inhalation):
No data was available.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
