Additional information

Acute oral toxicity:

BASF (1968) reported an acute oral LD50 value of 7712 mg/kg for male and female rats. Animals were given doses of about 3200, 6400, 8000 and 10000 µL/kg. Clinical signs seen were depression and narcosis. No mortalities were seen in the low dose group, 5 of 20 rats died in th 6400 µL/kg dose group, 16 of 20 rats died in the 8000 µL/kg dose group and 19 of 20 rats died in the 10000 µL/kg dose group.

Acute inhalation toxicity:

BASF (1961) reported an inhalation hazard test. Rats inhaled a saturated atmosphere at 20°C for 8 hours. No symptoms and no mortalities were observed.

Tyl (1985) reported a teratogenicity study using rats and mice. Concentrations of 0.15, 1 or 2.5 mg/L were given as aerosol concentrations using male and female rats. From this study, an acute inhalative LC50 value was derived being > 2.5 mg/L air for a six-hour exposure for male and female rats.

According to the results mentioned above, classification proposal concerning acute inhalation toxicity could not be done.

Acute dermal toxicity:

Tyl (1988) reported a developmental toxicity study using mice. Male and female animals were given doses of about 404 mg/kg, 1677 mg/kg and 3549 mg/kg under occlusive conditions. From this study, an acute dermal LD50 value of > 3500 mg/kg for male and female mice was derived.

According to the results of this developmental toxicity study, classification regarding acute dermal toxicity is not warranted.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The substance is legally classified for acute toxicity category 4 (H302: "Harmful if swallowed") according to Annex VI CLP Regulation. However, regarding available reliable experimental test data provided in this dossier the substance would not need to be classified for acute toxicity under Regulation (EC) No 1272/2008, as amended for the fifteenth time in Regulation (EU) No 2020/1182.
