Animal identification: colour code using picric acid
The animals were kept under conventional laboratory conditions. They were caged in groups of 5 in Macrolon cages type 3 with standardized soft wood bedding.
The animal room was air conditionned: temperature 22+/-3°C, relative humidity 55+/- 15%, 12 hours light/day, approximately 15 air changes/h.
A standardized animal laboratory diet as well as water were available ad libitum. Prior to dosing, the animals were fasted overnight.

Daily check for mortality (a.m.and p.m.) on working days.
Daily check for signs and symptoms.
Body weight determination on days 1, 7, 14 and at death
Spontaneously died animals were subjected to a gross necropsy as soon as possible; survivors at the end of the observation period.
Prior to dosing, the animals were fasted overnight. - Statistics:
- yes
From the body weights, the group means and their standard deviations were calculated. Where feasable, the LD50 including the 95% confidence limit were computed by the logit method (J. Berkson, J.Am.Stat. Ass. 39. 357-65, 1944) - Sex:

- Executive summary:
The acute oral toxicity of the test item was investigated in rats according to the OECD guideline No 401. The test item was administered orally by gavage to 5 males and 5 females per dose group. Four different concentrations were examined (500, 1000, 2500 and 5000 mg/kg bw). No death occurred in males after administration of 500, 1000 and 2500 mg/kg bw. After administration of 500 and 1000 mg/kg bw in females no deaths were observed, too. 3 out of 5 females dosed with 2500 mg/kg bw of the test item died within 2 days after application. After administration of 5000 mg/kg bw all animals (males and females) died within 3 hours. No compound related gross organ changes were observed. The acute oral median lethal dose (LD50) of the test item in the rat was estimated to be greater than 2000 mg/kg bw.

Additional information
Acute oral toxicity
The acute oral toxicity of the test item was investigated in rats according to the OECD guideline No 401. The test item was administered orally by gavage to 5 males and 5 females per dose group. Four different concentrations were examined (500, 1000, 2500 and 5000 mg/kg bw). No death occurred in males after administration of 500, 1000 and 2500 mg/kg bw. After administration of 500 and 1000 mg/kg bw in females no deaths were observed, too. 3 out of 5 females dosed with 2500 mg/kg bw of the test item died within 2 days after application. After administration of 5000 mg/kg bw all animals (males and females) died within 3 hours. No compound related gross organ changes were observed. The acute oral median lethal dose (LD50) of the test item in the rat was estimated to be greater than 2000 mg/kg bw.
Justification for selection of acute toxicity – oral endpoint
Reliable guideline study with acceptable restrictions
Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available study is considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance is not considered to be classified for acute toxicity under Directive 67/548/EEC, as amended for the 31st time in Directive2009/2/EC.
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data is reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is not considered to be classified for acute toxicity under Regulation (EC) No 1272/2008, as amended for the fifth time in Directive EC 944/2013.
