Description of key information
Acute oral toxicity
One reliable acute toxicity study via the oral route is available. After a single exposure to rats of 2000 mg/kg, the LD50 was established as greater than 2000 mg/kg bw (TalviOja, 2006). Based on these results, the test substance is considered not classified as an acute oral toxicant.
Acute toxicity via inhalation
No study was available for this endpoint. Therefore the endpoint has been waived:
In addition to the oral route of exposure, for substances other than gases, the information mentioned under REACH section 8.5.2 to 8.5.3 shall be provided for at least one other exposure route (REACH Regulation, column 2 adaptation of Annex VIII). For this substance, a key study is available for the dermal route of exposure. Therefore, an acute inhalation toxicity study should not be performed.
Acute dermal toxicity
One reliable acute toxicity study via the dermal route was available.After single dermal administration to rats of both sexes, observed over a period of 14 days, the LD50 was found to be greater than 2000 mg/kg body weight (Ott, 2006). Based on these results, the test substance is considered not classified as an dermal toxicant.

Additional information
Acute oral toxicity
One reliable acute toxicity study via oral administration is available.
In this study, 5 male and 5 female Sprague-Dawley rats were dosed on a single occasion with the test substance in polyethylene glycol (PEG 300) at 2000 mg/kg bw (according to OECD guideline 423 and GLP; TalviOja, 2006). During the subsequent 14-day observation period, no deaths or significant toxicity-related clinical signs were observed. The slightly ruffled fur and hunched posture that was seen resolved in about 5 hours. Body weight gain showed only minor deviations in one animal (1.3% loss), and macroscopic examination at necropsy demonstrated no deviations.
The LD50 was higher than 2000 mg/kg bw. No signs of toxicity were observed at this dose. Based on these results, the test substance is considered not classified as an acute oral toxicant.
Acute inhalation toxicity
There was no reliable acute inhalation study available. Therefore the study has been waived:
In addition to the oral route of exposure, for substances other than gases, the information mentioned under REACH section 8.5.2 to 8.5.3 shall be provided for at least one other exposure route (REACH Regulation, column 2 adaptation of Annex VIII). For this substance, a key study is available for the dermal route of exposure. Therefore, an acute inhalation toxicity study should not be performed.
Acute dermal toxicity
In this study, 5 male and 5 female Sprague-Dawley rats were dosed on a single occasion with the test substance in polyethylene glycol (PEG 300) (according to OECD 402 guideline and GLP; Ott, 2006). 0.5 g/mL of the test substance was applied to the backs of the animals (10% of total body surface), and covered with a semi-occlusive dressing. 24 hours after dosing, the dressing was removed and the area washed with lukewarm tap water. Observations at 1, 2, 3 and 5 hours after administration on test day 1, and twice daily during days 2-15 showed no test-item related mortality, clinical signs or body weight effects. Based on these results, the test substance is considered not classified as an acute dermal toxicant.
Justification for classification or non-classification
Acute oral toxicity
The LD50 is greater than 2000 mg/kg bw and therefore the test substance is considered not classified as an acute oral toxicant according to the CLP Regulation.
Acute inhalation toxicity
There was no reliable acute inhalation study available. Therefore no classification can be derived for acute inhalation toxicity.
Acute dermal toxicity
The LD50 is greater than 2000 mg/kg bw, and therefore the test substance is considered not classified as an acute dermal toxicant according to the CLP Regulation.
