Endpoint summary
Administrative data
Description of key information
Oral and dermal toxicity studies were conducted to recognised training guidelines with GLP.
Inhalation study waived as only 10% of
substance particles are capable of entering broncho-alveolar tract. As
the substance shows no toxicity potential for oral/dermal, and no
irritation potential for skin/eye, in the interests of animal welfare an
inhalation study is regarded as not scientifically necessary.
Key value for chemical safety assessment

The test was conducted on male/female rats, administered by oral gavage with a vehicle of 0.5 % carboxymethylcellulose and 0.1 % polysorbate 80 in distilled water, at two different concentrations (2000 mg/kg bw and 5000 mg/kg bw). No mortality was observed, thus the test material is not classified as acutely toxic (oral) under CLP regulation 1272/2008.

The test was conducted on rats (male/female) using a single dose of 2000 mg/kg bw and the test material was applied using a vehicle of peanut oil and held in place using a semiocclusive cover. As no mortalities occured the test material is not classified as acutely toxic (dermal) under CLP regulation 1272/2008.

Additional information
After single oral application of 2000 and 5000 mg/kg bw test article by gavage to male and female rats according to OECD 401 (1981) no mortality occurred. Dyspnea, exophthalmos, ruffled fur, and abnormal body position were seen. In both groups animals recovered within 11 days. Therefore, the LD50 is greater than 5000 mg/kg bw.
After dermal application of 2000 mg/kg bw test article to female and male rats for 24 h according to OECD 402 no mortality occurred. Clinical symptoms (piloerection, abnormal body positions, and dyspnea) of slight severity were seen. The animals recovered within 7 to 9 days. Therefore, the LD50 is greater than 2000 mg/kg bw for both sexes.
No experimental data for inhalative toxicity are available. However, gravimetric data are available which showed a mass median aerodynamic diameter of 55 µM when using the mass distribution method. Only 10 % of particles have a diameter below 20 µm (BASF KA-88/10 C; see chapter 4.5 of IUCLID). Therefore, the majority of generated particles is not expected to penetrate into the broncho-alveolar tract. Moreover, the substance showed neither a general toxic potential (LD 50 acute oral above 5000 mg/kg bw, LD 50 acute dermal above 2000 mg/kg bw), nor a irritating potential (skin and eye). Based on these data and with respect to animal welfare an acute inhalation study was not performed.
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. 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 fifth time in Directive EC 944/2013.
