- Executive summary:
In an acute oral toxicity study (limit test) performed according to OECD Guideline 423 and in compliance with GLP, 3 female Sprague Dawley rats were given a single oral (gavage) dose of test item at 2000 mg/kg bw and then 6 female Sprague Dawley rats were given a single oral (gavage) dose of test item at 300 mg/kg bw. Animals were then observed for mortality, clinical signs and bodyweights for 14 days and were all sacrificed for macroscopic examination.
It was noted the death of two rats treated at 2000 mg/kg b.w. (2/3). The mortalities were preceded by decrease in spontaneous activity (2/2) and piloerection (1/2). Rigor mortis was noted before the necropsy (2/2). Decrease in body weight was noted in the two animals on the day of the death compared to day 0 (between -11% and -15%) The macroscopic examination revealed a thinning of the forestomach and of the corpus (2/2) associated with black and red spots on the forestomach and on the corpus (2/2). In the surviving animal treated at 2000 mg/kg b.w. (1/3), a decrease in spontaneous activity, bradypnea, total ptosis, and piloerection were noted during the first days of the test. The animal recovered a normal behaviour at 48 hours post-dose. An absence in body weight gain was noted on day 2 compared to day 0. Then, the body weight evolution remained normal. The macroscopic examination of this animal at the end of the study did not reveal treatment related changes.
No mortality occurred in animals treated at 300 mg/kg. A decrease in spontaneous activity (3/6), and piloerection (2/6) were noted during the first hours of the test. The animals recovered a normal behaviour at 4 hours post-dose. The body weight evolution remained normal during the study.The macroscopic examination of the animals at the end of the study did not reveal treatment related changes.
Under the test conditions, the oral LD50 for test item is higher than 300 mg/kg and lower than 2000 mg/kg bw and the LD50 cut-off may be considered as 1000 mg/kg bw in female rats. Therefore, it must be classified in Category 4 (H302: Harmful if swallowed) according to the CLP Regulation (EC) No. 1272/2008 and Globally Harmonized System (GHS).
This study is considered as acceptable and satisfies the requirement for acute oral toxicity endpoint.

Dryness was noted on day 3 in all females and was totally reversible between days 5 and 8. All animals showed gains in body weight over the observation period. No abnormalities were noted at necropsy.
Dermal LD50 Combined > 2000 mg/kg bw
Under the test conditions, the test material is not classified according to the annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.

Additional information
Acute toxicity: oral
A key study was identified (Phycher, 2013, rel. 1). In this acute oral toxic class method study performed according to the OECD guideline No. 423 and in compliance with GLP, three female Sprague Dawley rats received a single oral (gavage) dose of the test substance at a dose level of 2000 mg/kg bw and then 6 female Sprague Dawley rats were given a single oral (gavage) dose of test item at 300 mg/kg bw. Animals were then observed for mortality, clinical signs and bodyweights for 14 days and were all sacrificed for macroscopic examination.
It was noted the death of two rats treated at 2000 mg/kg b.w. (2/3). The mortalities were preceded by decrease in spontaneous activity (2/2) and piloerection (1/2). Rigor mortis was noted before the necropsy (2/2). Decrease in body weight was noted in the two animals on the day of the death compared to day 0 (between -11% and -15%) The macroscopic examination revealed a thinning of the forestomach and of the corpus (2/2) associated with black and red spots on the forestomach and on the corpus (2/2). In the surviving animal treated at 2000 mg/kg b.w. (1/3), a decrease in spontaneous activity, bradypnea, total ptosis, and piloerection were noted during the first days of the test. The animal recovered a normal behaviour at 48 hours post-dose. An absence in body weight gain was noted on day 2 compared to day 0. Then, the body weight evolution remained normal. The macroscopic examination of this animal at the end of the study did not reveal treatment related changes.
No mortality occurred in animals treated at 300 mg/kg. A decrease in spontaneous activity (3/6), and piloerection (2/6) were noted during the first hours of the test. The animals recovered a normal behaviour at 4 hours post-dose. The body weight evolution remained normal during the study.The macroscopic examination of the animals at the end of the study did not reveal treatment related changes.
Oral LD50 > 300 mg/kg bw - < 2000 mg/kg bw and the LD50 cut-off may be considered as 1000 mg/kg bw.
Acute toxicity: dermal
A key study was identified (Phycher, 2013, rel.1). In this acute dermal toxicity study (limit test) performed according to OECD Guideline No. 402 and in compliance with GLP, a group of SD rats (5/sex) was given a single dermal application of the undiluted test material to intact skin of the back and flank area at a dose level of 2000 mg/kg bw. Test sites were covered with a semi-occlusive dressing for 24 h. 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. Skin irritation was assessed and scored according to the Draize scale at 24 h after removal of the dressings and then daily for 14 days.
No mortality or systemic toxicity was observed. Cutaneous reactions (erythema) were noted from 24 hours post-dose in all animals and were totally reversible on day 2 in males and on day 8 in females. Dryness was noted on day 3 in all females and was totally reversible between days 5 and 8. All animals showed gains in body weight over the observation period. No abnormalities were noted at necropsy.
Dermal LD50 Combined > 2000 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 (CLP).
Self classification:
Acute toxicity (Oral):
Based on the available information, the substance is classified in Category 4 (H302: Harmful if swallowed) according to the CLP and to the GHS.
Acute toxicity (Dermal):
Based on the available information, the substance is:
- not classified according to the CLP as the dermal LD50 is higher than 2000 mg/kg bw
- not classified according to the GHS since there is no reliable evidence that indicates the LD50 to be in the range of Category 5 values (GHS criteria not met).
Acute toxicity (Inhalation):
No information 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 CLP and to the GHS 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 CLP and to the GHS are not met since narcotic effects were not observed in the acute oral toxicity study.
Specific target organ toxicity: single exposure (Dermal):
The classification criteria according to the CLP and to the GHS as specific target organ toxicant (STOT) – single exposure, dermal 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 (dermal) for a Category 1 classification (C≤ 1000 mg/kg bw) and at the guidance value (dermal) for a Category 2 classification (2000 mg/kg bw ≥ C > 1000 mg/kg bw). No classification is required.
The criteria for Transient Organ effects (STOT-SE Category 3) according to the CLP and to the GHS are not met since narcotic effects were not observed in the acute dermal toxicity study.
Specific target organ toxicity: single exposure (Inhalation):
No information was available. Not required for substances at the REACH Annex VII tonnage level.
Aspiration hazard:
The substance is not a hydrocarbon and no effects were observed on lungs in oral studies, therefore the criteria for aspiration toxicity according to the CLP and to the GHS are not met.
