- Executive summary:
In an acute oral toxicity study, Sprague-Dawley rats (10 animals/sex/dose) were given a single oral (gavage) dose of test substance at 5000 mg/kg bw. Animals were then observed for mortality, clinical signs and bodyweights for 2 -weeks and at the end of the study the surviving animals were sacrificed for macroscopic examination.
No mortalities occurred and no signs of systemic toxicity were observed during the 14-day observation period. All animals showed body weight gain during the study period. No abnormalities were noted at necropsy of animals that were killed at the end of the study.
Under the test conditions, the oral LD50 of the test substance is higher than 5000 mg/kg bw therefore it is not classified for acute oral toxicity according to the CLP Regulation EC No. (1272/2008) and to the GHS.

Additional information
Two studies were identified and used in a weight of evidence approach (Newell, 1976a ; Newell, 1976b).
In the first acute oral toxicity study performed similarly to the OECD guideline No. 401, Sprague-Dawley rats (10 animals/sex/dose) were given a single oral (gavage) dose of test substance at 5000 mg/kg bw.
In the second study, ICR/SIM mice (10 animals/sex/dose) were exposed in the same manner.
There were no deaths during both studies.
All male mice had a rough hair coat during the first 4 days post-treatment, but the coat returned to normal thereafter.
All rats and female mice showed no clinical signs.
All animals showed expected gains in bodyweight over the study period.
No gross abnormalities were noted for the animals necropsied at the conclusion of the study.
Oral LD50 > 5000 mg/kg bw
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 and to the GHS as the LD50 is greater than 5000 mg/kg bw (GHS criteria not met).
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.
The criteria for Transient Organ effects (STOT-SE Category 3) according to Annex VI of 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.
Specific target organ toxicity: single exposure (Inhalation):
No data was available.
