Additional information

For the acute toxicity, analogue substances were tested.

For the acute oral toxicity five females of Wistar at limit dose of ca. 2000 mg/kg bw were dosed Under the experimental conditions the LD50, f, > 2000 mg/kg bw. No mortality or signs of toxicity were observed.


No deaths or clinical signs related to substance exposure were recorded for the acute dermal toxicity test, with a LC50 > 2000 mg/kg.

Based on the read across considerations same results apply to the target substance.

Justification for classification or non-classification

According to the CLP Regulation (EC n. 1272/2008), table 3.1.1, Acute toxicity hazard categories and acute toxicity estimates (ATE) defining the respective categories:

For Acute toxicity oral route:

Category 1: ATE <= 5 mg/kg bw

Category 2: 5 < ATE <= 50 mg/kg bw

Category 3: 50 < ATE <= 300 mg/kg bw

Category 4: 300 < ATE <= 2000 mg/kg bw

The LD50 of the test substance was determined to be > 2000 mg/kg bw in the chosen reference test, which is outside the limits for classification
