Additional information

Oral

The acute oral toxicity of the test substance was assessed in a study with rats according to OECD Guideline 425 and in compliance with GLP (Lowe, 2016). The test substance was applied via gavage as 30% dilution in water. A dose of 2000 mg/kg bw (limit test) test substance was administered to one female (first step). As this animal survived, another four animals were dosed with 2000 mg/kg bw. Animals were observed for mortality and general clinical condition 30 min after administration up to several hours and daily for 14 days thereafter. Body weights were recorded before administration and on Days 6 or 7 and 14. Macroscopic examination and histopathology was performed in the end of the observation period at terminal sacrifice. None of the animals died and no clinical symptoms were observed during the study. The body weight gain was not affected by the administration of the test substance. No abnormalities were noted at necropsy. Based on the results of this study, the oral LD50 value was determined to be > 2000 mg/kg bw in rats.

 

In a supporting study, the acute oral toxicity was assessed in a study equivalent to OECD Guideline 401 with limited documentation (Bouffechoux, 1995). A single oral dose of 2000 mg/kg bw (limit test) was given to 5 female Swiss mice. Animals were observed for mortality, body weight, general clinical signs and behavior for 14 days. None of the animals died and no clinical symptoms or changes in behavior were observed during the study. The body weight gain was not affected by the administration of the test substance. Based on the results of this study, the oral LD50 was determined to be > 2000 mg/kg bw in mice. This study was not taken into account for hazard assessment.

 

Dermal

The acute dermal toxicity of the test substance was assessed in a limit test performed in 5 male and 5 female Wistar rats according to OECD Guideline 402 and in compliance with GLP (Lowe, 2015). A single dose of 2000 mg/kg bw of the test substance was applied to the clipped skin of rats under occlusive conditions for 24 hours. Animals were observed for mortality and general clinical condition for several hours after dosing and daily for 14 days thereafter. Body weights were recorded on Day 0, 7 and 14. Macroscopic examination and histopathology was performed in the end of the observation period at terminal sacrifice. None of the animals died and no clinical symptoms were observed during the study. The body weight gain was not affected by the administration of the test substance. No abnormalities were noted at necropsy. Based on the results of this study, the dermal LD50 value was determined to be > 2000 mg/kg bw in rats.

 

Justification for classification or non-classification

The available data on acute oral and acute dermal toxicity of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification.
