Endpoint summary
Administrative data
Description of key information
The LD50 for acute oral toxicity was
determined to be > 2000 mg/kg bw and the LD50 for acute dermal toxicity
was determined to be > 5000 mg/kg bw. Therefore, the test item is not
considered to cause acute toxicity via oral or demal route.

Additional information
Acute toxicity via the oral route:
The assessment of the acute toxicity via the oral route for the test substance is based on 2 study records used in a Weight of Evidence approach. In the first study record, for assessment of the acute oral toxicity the test item (10% active ingredient in water), was administered by single gavage to rats, at dose levels of 15400, 23100, 34600 and 51900 mg/kg bw (IBT,1963). Each test group comprised 2 male and 2 female animals. The testing method in principle was similar to the OECD TG 401. 100% (4/4) mortality was observed at 51900 mg/kg bw, 50% (2/4) mortality was observed at 34600 mg/kg bw and 25% (1/4) mortality was observed at 23100 mg/kg bw, whereas no mortality occurred at 15400 mg/kg bw dose group. Hence the LD50 was set to 31300 mg/kg bw. Taking the dilution factor into account the LD50 was found to be 3130 mg/kg bw (calculated for active ingredient). In the other study record the test item (16% active ingredient), was administered by single gavage to mice at dose levels of 10, 15 and 20 ml/kg bw (PSL, 1982). Each test group comprised 5 male and 5 female animals. The testing method in principle was similar to the OECD guideline 401. The following mortality was observed: At the dose of 20 mL/kg bw, 5/5 males and 4/5 females died. At the dose of 15 mL/kg bw and at the dose of 10 mL/kg bw no mortality was observed. The LD50 was calculated as 17.8 mL/kg bw. Taking the dilution factor into account the LD50 was found to be 2.85 mL/kg bw.
Acute toxicity via the dermal route:
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 5000 mg/kg bw of the test substance (as suspension inolive oil Ph.Eur.) to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours according to OECD 402. The application area comprised at least 10% of the total body surface area. The animals were observed for 14 days. The following test item-related local effects were recorded during the course of the study: Very slight to well-defined erythema (grade 1 to 2), very slight edema (grade 1), incrustations and scaling. The mean body weight of the male animals increased within the normal range throughout the study period. The mean body weight of the female animals did not significantly change during the first post-exposure observation week. This effect is observed at times in the rat strain used, because in the required age range the female animals have already reached the phase of slow growth. No signs of systemic toxicity 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 LD50, dermal, rat > 5000 mg/kg bw (BASF, 2013).
For assessment of the acute dermal toxicity the test item was applied onto the clipped dorsal skin of rabbits, under occlusive conditions, for 24 hours. The test conduct was in principle similar to the OECD TG 402. The tested dose levels were 6800 and 10200 mg/kg bw. After removal of the dressing, the animals were observed over a period of 14 days. Since neither mortality nor clinical symptoms of toxicity were observed, the LD0 was set at 10200 mg/kg bw; no LD50 was derived. Taking the dilution factor into account the LD0 was found to be 1020 mg/kg bw (calculated for active ingredient) (IBT, 1963).
Justification for classification or non-classification
Based on the available information classification for acute oral and dermal toxicity is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
