- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:

- Mortality:
- No mortality occurred.
- Clinical signs:
- No systemic clinical signs were observed during clinical examination.
- Body weight:
- The body weight of all male animals and three out of five female animals increased within the normal range throughout the study period. One female animal showed stagnation of body weight during the first week, but gained weight in a normal range during the second week. Another female showed stagnation of body weight during the whole observation period. Due to the fact that stagnation or slight loss of body weight is commonly known for females after dermal applications, this stagnation is considered to be unspecific.
- Gross pathology:
- No macroscopic pathologic abnormalities were noted in the animals (5 males and 5 females) examined on the last day of observation.
- Other findings:
- - Other observations: No local effects were observed.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute dermal median lethal dose (LD50) was determined to be > 2000 mg/kg body weight.
- Executive summary:
In an acute dermal toxicity study (Limit Test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of the test item (as suspension in corn oil Ph.Eur.). The clipped application site (dorsal and dorso-lateral parts of the trunk, comprising at least 10% of the total body surface) was covered by semi-occlusive dressing during the 24-hour exposure period. The animals were observed for 14 days. Neither clinical signs nor local skin effects or mortality were observed in the animals. No macroscopic pathologic abnormalities were noted in the animals examined at the end of the study.
Accordingly, the acute dermal median lethal dose (LD50) was determined to be > 2000 mg/kg body weight.

Additional information
Acute oral toxicity
In a GLP-compliant acute oral toxicity study performed according to OECD guideline 423, 2000 mg/kg bw of the test item (preparations in corn oil Ph.Eur.) were administered by gavage to two test groups of three fasted Wistar rats each (6 females). In the first as well as in the second test group no mortality occurred and no clinical signs were observed. The body weights increased within the normal range throughout the study period and there were no macroscopic pathological findings at the end of the observation period. Therefore, the acute oral LD50 was calculated to be LD50, oral, rat > 2000 mg/kg bw.
Acute dermal toxicity
In a GLP-compliant acute dermal toxicity study (Limit Test) following OECD guideline 402, young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of the test item as suspension in corn oil. The clipped application site (dorsal and dorso-lateral parts of the trunk, comprising at least 10% of the total body surface) was covered by semi-occlusive dressing during the 24-hour exposure period. The animals were observed for 14 days. Neither clinical signs nor local skin effects or mortality were observed in the animals. The body weight of all male animals and three out of five female animals increased within the normal range throughout the study period. One female animal showed stagnation of body weight during the first week, but gained weight in a normal range during the second week. Another female showed stagnation of body weight during the whole observation period. Due to the fact that stagnation or slight loss of body weight is commonly known for females after dermal applications, this stagnation is considered to be unspecific. No macroscopic pathologic abnormalities were noted in the animals examined at the end of the study. Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat >2000 mg/kg bw.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Both for oral and dermal administration the LD50 was greater than 2000 mg/kg bw. As a result the substance is not considered to be classified for acute oral or dermal toxicity under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EU) No 2017/776.
