- Executive summary:
In this guideline (OECD 402) study conducted with GLP certification, the acute dermal LD50 of the test material (EC 444-860-9) to the rat was determined to be >2000 mg/kg bw (both sexes). The test material was administered under occlusive conditions as a limit test (2000 mg/kg bw) to male and female for 24 hours, with a post application observation period of 15 days. The result of the test does not trigger classification of the test material as acutely toxic according to the EU Classification, Labelling, and Packaging (CLP) regulation (1272/2008).
Reference
The median lethal dose of the test item after single dermal administration to rats of both sexes, observed over a period of 15 days is: LD50 (rat): greater than 2000 mg/kg bw.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
Additional information
A single dose of the test item was administered by gavage to male and female rats at concentrations of 2000 mg/kg bw. The animals were observed for 14 days. Mortality, body weight and clinical signs were recorded continuously. Organ weighing and gross necropsy was performed after scheduled sacrifice.
A single dose of the test item was applied onto skin of male and female Wistar rats at concentrations of 2000 mg/kg bw. The animals were observed for 14 days. Mortality, body weight and clinical signs were recorded continuously. Organ weighing and gross necropsy was performed after scheduled sacrifice.
No mortality occurred in any of the two studies. Clinical signs of toxicity, i.e. hunched posture, ruffled fur and emaciation were observed after oral administration in male and female animals. Gross necropsy did not reveal any findings. The LD50 is therefore considered to be > 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 1272/2008. A single dose of the test item was administered orally or dermally to Wistar rats at concentrations of 2000 mg/kg bw. No mortality occurred. Clinical signs of toxicity, i.e. hunched posture, ruffled fur and emaciation were observed after oral administration in male and female animals. Gross necropsy did not reveal any findings. The LD50 is therefore considered to be > 2000 mg/kg bw. As a result the substance is not considered to be classified for acute toxicity under Regulation (EC) No. 1272/2008.
