Additional information
Oral:
In a GLP conform acute oral toxicity study conducted according to OECD 423 (BASF SE, 10A0731/11X589, 2013; reliability score 1) two groups of Wistar rats (2 x 3 female animals) were given a single oral dose (via gavage) of the test substance (unchanged, no vehicle) at a limit dose of 2000 mg/kg bw and observed for 14 days.
Oral LD50 (females) > 2000 mg/kg bw, expected to be less than 5000 mg/kg bw
One animal of the first 2000 mg/kg bw test group was found dead in the cage on study day 2 and one animal of the second 2000 mg/kg bw test group was sacrificed in a moribund state on study day 3. Clinical signs in the first 2000 mg/kg bw test group revealed in two out of three animals impaired general state and piloerection from study day 1 until study day 6 after administration. In one of these animals dyspnoea and reduced defecation were observed on study day 1 only and in the other animal on study day 1 and 2 after administration. In the third animal impaired general state, dyspnoea, piloerection and missing defecation was noted on study day 1 after administration (this animal was found dead in its cage on study day 2). The mean body weight of the surviving animals in the test groups increased throughout the study period within the normal range. The deceased animal (first group) and the animal, which was sacrificed in a moribund state (second group), lost body weight. The following macroscopic pathologic findings were observed in the animals that died: extensive haemorrhage of the glandular stomach, red discoloration and reddish content of the small intestine, congestion of the kidneys. There were no macroscopic pathological findings in the animals sacrificed at the end of the observation period.
Dermal:
In a GLP conform acute dermal toxicity study (BASF SE, 11A0731/11X590, 2013; reliability score 1) according to OECD 402 groups of Wistar rats (5 animals / sex) were dermally administered a limit dose of 2000 mg/kg bw of the test substance (unchanged, no vehicle) with a semiocclusive coverage for 24 h and observed for 14 days.
Dermal LD50(males/females) > 2000 mg/kg bw
No mortality occurred. No systemic clinical signs were observed during clinical examination. Skin effects at the application site comprised well-defined erythema (grade 2) in all male animals 1 day after application which persisted in one animal until study day 2. This animal showed moderate erythema (grade 3) on day 3. On study day 2, moderate erythema (grade 3) was observed in four male animals and persisted in 3 animals until day 3, in the fourth animal moderate erythema was observed until day 7. Thereafter well-defined erythema was noted in the animals until day 7, 8 or 9, respectively. Afterwards very slight erythema (grade 1) was observed until day 8, 10 or 13, respectively. Slight edema (grade 2) was noted in all male animals from study day 1 until study day 3 after application and persisted in two of these animals until study day 7. On study day 8 very slight edema (grade 1) was noted in these two animals. The other three animals showed very slight edema from study day 6 until study day 7, 8 or 9, respectively. Incrustations were observed in all male animals from study day 3 until day 10 or 13, respectively. In one animal plate-like incrustations were noted on study day 6 and 7. The mean body weights of the male animals increased within the normal range throughout the study period. The mean body weight of the female animals slightly increased or stagnated during the first post-exposure observation week, probably due to the bandage procedure, but increased during the second week within the normal range. No macroscopic pathologic abnormalities were noted in the animals examined on the last day of observation.

Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available studies are considered reliable and suitable for classification purposes under 67/548/EEC. The LD50 values are above 2000 mg/kg bw. As a result the substance is not considered to be classified for acute oral and dermal toxicity under Directive 67/548/EEC, as amended for the 31st time in Directive 2009/2/EG.
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. The LD50 values are above 2000 mg/kg bw. As a result the substance is not considered to be classified for acute oral and dermal toxicity under Regulation (EC) No. 1272/2008, as amended for the third time in Directive (EC 618/2012).
The substance requires classification for UN GHS acute class 5 for the oral route.
