CLASS METHOD
- Rationale for the selection of the starting dose: By request of the sponsor a starting dose of 300 mg/kg bw was administered to 3 female rats in the first step. Because no mortality occurred, 500 mg/kg bw were administered to another group of 3 female animals in the second step. As all animals died in this step, 300 mg/kg bw were administered to another group of 3 female animals in the third step. As in this step only one animal died, the study was terminated. - Doses:
- 300 and 500 mg/kg bw
- No. of animals per sex per dose:
- 3 for 500 mg/kg bw, 6 for 300 mg/kg bw in two groups
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Clinical signs for each animal were recorded several times on the day of administration and at least once during each workday thereafter. Individual body weights shortly before administration (day 0), weekly thereafter and on the last day of observation and on the day of death starting.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight - Statistics:
- Calculations were performed using Microsoft Excel 2003 and checked with a calculator.
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 300 - < 500 mg/kg bw
- Based on:
- test mat.
- Mortality:
- 500 mg/kg bw: all 3 animals dead on day 2
300 mg/kg bw: no mortality in first test group, 1 animal dead on day 2 in second group - Clinical signs:
- 500 mg/kg bw: impaired general state, piloerection and cowering position (starting 1 h after administration, on day 1)
300 mg/kg bw: impaired general state, piloerection from 1 h after treatment up to 3 days. One animal that died showed dyspnea and staggering. - Body weight:
- 500 mg/kg bw: Animals showed a reduced body weight after death.
300 mg/kg bw: Animals showed a normal increase in body weight during the study period. The animal that died showed a reduced weight after death. One animal lost weight during the second week of treatment (most probably due to normal slow growth in the age range). - Gross pathology:
- 500 mg/kg bw: Animals showed congestion of the kidneys, liver light red with dark spots, red discoloration of the fully-filled stomach, red discoloration of the small intestine with red discolored contents and red discoloration of the urinary bladder contents.
300 mg/kg bw: The animal that died showed congestion of the kidneys, light and dark spots on the liver, red discoloration of the glandular stomach and red discoloration of the small intestine with red discolored contents. Animals that were killed after the observation period showed no macroscopic changes.

- Body weight:
- Body weight of male animals increased within normal range.
One female showed a loss of body weight. Two females showed a stagnation of body weight in the first week but otherwise the increase was normal. One female showed a constant stagnation during the complete observation period. Due to the fact that stagnation or slight loss of body weight is commonly known for females dermally applied and the affected animals neither showed any clinical symptoms nor change in behavior these findings are considered to be unspecific. - Gross pathology:
- No macroscopic pathologic abnormalities were observed.

Additional information
Acute toxicity
Oral
An acute oral toxicity study with the test substance was conducted in rats according to OECD TG 423. Female animals received 500 mg/kg bw (3) or 300 mg/kg bw (6) one time via gavage and were observed for 14 days. All animals of the 500 mg/kg bw treatment group died within the first two days. From the 300 mg/kg bw treatment group one animal died within the first two days while the other animals survived the observation period. Animals that died showed a reduced body weight after death while the surviving animals showed a body weight development within the normal range and expectation of the animals development status. All animals presented with an impaired general state and piloerection. Those clinical signs lasted up to three days in the survivors and were not detected afterwards. Gross pathology of the survivors showed no macroscopic changes. Animals that died showed congestion of the kidneys, light and dark spots on the liver, liver light red with dark spots, red discoloration of the fully-filled stomach, red discoloration of the glandular stomach, red discoloration of the small intestine with red discolored contents and red discoloration of the urinary bladder contents. Due to those observations the acute oral LD50 was determined to be in the range of > 300 < 500 mg/kg bw in rats. Therefore the test substance is considered to be classified for acute oral toxicity in Category 4 according to CLP.
Dermal
An acute dermal toxicity study in rats was performed according to OECD TG 402. The limit test was conducted with a semiocclusive application of 2000 mg/kg bw on clipped skin. The test substance was applied for 24 h and removed afterwards. The animals were observed for 14 days. No clinical signs were detected. All male and two female animals showed a development of body weight that was within the normal range of weight gain. Three females showed stagnation/loss of bodyweight which was, due to a lack of alterations in behavior and clinical signs, explained as a commonly observed effect after dermal application to female rats. Pathology showed no abnormalities in all animals. Therefore the acute dermal LD50 of the test substance was determined to be > 2000 mg/kg bw in rats.
Justification for selection of acute toxicity – oral endpoint
The study is considered reliable.
Justification for selection of acute toxicity – dermal endpoint
The study is considered reliable.
Justification for classification or non-classification
Acute oral toxicity
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data is reliable and suitable for classification purposes under Regulation (EC) No 1272/2008, as amended for the seventh time in Regulation (EC) No 2015/1221. As a result the substance is considered to be classified for acute oral toxicity in Category 4. H302: Harmful if swallowed
Acute dermal toxicity
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data is reliable and suitable for classification purposes under Regulation (EC) No 1272/2008, as amended for the seventh time in Regulation (EC) No 2015/1221. As a result the substance is considered to be not classified for acute dermal toxicity.
