- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- not determinable due to absence of adverse toxic effects
- Mortality:
- - No mortality was observed at 2000 mg/kg bw.
- Clinical signs:
- other: - A very slight piloerection was observed during the first 30 minutes. No other signs were observed until the end of the observation period.
- Gross pathology:
- - No abnormalities were noted at necropsy.
- Other findings:
- None
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the substance is not classified according to the Regulation EC No. 1272/2008 (CLP) as the oral LD50 is higher than 2000 mg/kg bw and no significant adverse effects were observed.
- Executive summary:
In an acute oral toxicity study (limit test) performed according to OECD Guideline No. 423 and in compliance with GLP, female Sprague-Dawley strain rats were administered a single oral dose of test material by gavage. Following a first study using three animals at a dose level of 2000 mg/kg bw, additional 3 animals were administered a single oral dose of test item at 2000 mg/kg bw. 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 was observed. A very slight piloerection was observed during the first 30 minutes. No other signs were observed until the end of the observation period. All animals showed expected gains in body weight over the 14 day study period. No abnormalities were noted at necropsy.
Rat Oral LD50 (females) > 2000 mg/kg bw
Under the test conditions, the substance is not classified according to the Regulation EC No. 1272/2008 (CLP) and to the GHS as the oral LD50 is higher than 2000 mg/kg bw and no significant adverse effects were observed.
This study is considered as acceptable and satisfies the requirement for acute oral toxicity endpoint.

Additional information
Acute toxicity: oral
A key study was identified on the substance (EVIC, 2010, rel.1). In this acute oral toxicity study (limit test) performed according to OECD Guideline No. 423 and incompliance with GLP, female Sprague-Dawley strain rats were administered a single oral dose of test material by gavage.Following a first study using three animals at a dose level of 2000 mg/kg bw, additional 3 animals wereadministered a single oral dose of test item at 2000 mg/kg bw. Animals were then observedfor mortality, clinical signs and bodyweights for 14 days and at the end of the study the surviving animalswere sacrificed for macroscopic examination.
No mortality was observed. A very slight piloerection was observed during the first 30 minutes. No other signs were observed until the end of the observation period. All animals showed expected gains in body weight over the 14 day study period. No abnormalities were noted at necropsy.

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 (CLP) and to the GHS as the oral LD50 is higher than 2000 mg/kg bw and no adverse effects were observed.
Acute toxicity via Dermal route:
No data was available. Not required for substances at the REACH Annex VII tonnage level.
Acute toxicity (Inhalation):
No data was available. Not required for substances at the REACH Annex VII tonnage level.
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.
The criteria for Transient Organ effects (STOT-SE Category 3) according to the Regulation (EC) No. 1272/2008 are not met since narcotic effects were not observed in the acute oral toxicity study.
Specific target organ toxicity: single exposure (Dermal):
No data was available. Not required for substances at the REACH Annex VII tonnage level.
Specific target organ toxicity: single exposure (Inhalation):
No data was available. Not required for substances at the REACH Annex VII tonnage level.
