Therefore it is not classified according to the Regulation (EC) N° 1272-2008 and according to the GHS. No signal word or hazard statement is required.
- Executive summary:
In an acute oral toxicity study (limit test) performed according to OECD Guideline No. 423 and in compliance with GLP, female HanRCC: WIST (SPF) rats were administered a single oral dose of test material diluted in PEG-300 by gavage.
The animals (6 females) received a single dose of the test item on a 2000 mg/kg bw and were then observed for mortality, clinical signs and bodyweights for 14 days and at the end of the study the surviving animals were sacrificed for macroscopic examination.
The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recorded. All animals were examined for clinical signs at approximately 30 minutes, 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2-15. Mortality/viability was recorded at approximately 30 minutes, 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2-15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically.
All animals survived until the end of the study period. One female showed slightly ruffled fur 2 to 5 hours after treatment and on test days 3 to 6. In the other five females the slightly ruffled fur was observed from test day 2 or 3 up to test days 5, 6, 7 or 8. Additionally, hunched posture was recorded in five females 2, 3 or 5 days post-treatment and persisted up to test days 3, 4, 5 or 6. Otherwise, no clinical signs were recorded in any animal at any observation.
The body weight of the animals was within the range commonly recorded for this strain and age.
No macroscopic findings were recorded at necropsy.
Under the test conditions, the oral LD50 of the test substance is > 2000 mg/kg bw in rats. In accordance with OECD Guideline 423, the LD50 cut-off of the test substance may be considered to be > 5000 mg/kg bw by oral route in the rat. Therefore it is not classified according to the Regulation (EC) N° 1272-2008 and according to the GHS. No signal word or hazard statement is required.
This study is considered as acceptable and satisfies the requirement for acute oral toxicity endpoint.

- Executive summary:
In an acute dermal toxicity study (limit test) performed according to the OECD test guideline No. 402 and in compliance with GLP, five male and five female rats were treated with the substance at 2000 mg/kg by dermal application. The test item was applied diluted in vehicle (PEG 300) at a concentration of 0.5 g/mL and administered at a volume dosage of 4 mL/kg. The test site was covered with a semi-occlusive dressing for 24 hours. Animals were observed for mortality, clinical signs, local signs and body weights for 14 days and at the end of the study the surviving animals were sacrificed for macroscopic examination.
No deaths occurred during the study. No clinical signs were observed during the course of the study.

One female did not gain weight at the end of the study. Otherwise, the body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were observed at necropsy.
Dermal LD50 Combined > 2000 mg / kg bw
Under the test conditions, the dermal LD50 for the registered substance is higher than 2000 mg/kg bw in rats therefore it is not classified according to the Annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
This study is considered as acceptable and satisfies the requirement for acute dermal toxicity endpoint.

ORAL
A key study was identified (RCC, 2008, rel. 1). In this acute oral toxic class method study performed according to the OECD guideline No. 423 and in compliance with GLP, six female HanRCC: WIST (SPF) rats received a single oral (gavage) dose of the test substance diluted in PEG-300 at a dose level of 2000 mg/kg bw. Animals were then observed for mortality, clinical signs and bodyweights for 14 days and were all sacrificed for macroscopic examination.
All animals survived until the end of the study period. One female showed slightly ruffled fur 2 to 5 hours after treatment and on test days 3 to 6. In the other five females the slightly ruffled fur was observed from test day 2 or 3 up to test days 5, 6, 7 or 8. Additionally, hunched posture was recorded in five females 2, 3 or 5 days post-treatment and persisted up to test days 3, 4, 5 or 6. Otherwise, no clinical signs were recorded in any animal at any observation. The body weight of the animals was within the range commonly recorded for this strain and age.

Dermal LD50 Combined > 2000 mg / kg bw
INHALATION
Not required
Justification for classification or non-classification
Harmonized classification:
The substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.
Self classification:
Acute toxicity (Oral)
Based on the available information, the substance is:
- not classified according to the CLP as the oral LD50 is higher than 2000 mg/kg bw
- not classified according to the GHS since there is no reliable evidence that indicates the LD50 to be in the range of Category 5 values (GHS criteria not met).
Acute toxicity (Dermal)
Based on the available information, the substance is:
- not classified according to the CLP as the dermal LD50 is higher than 2000 mg/kg bw
- not classified according to the GHS since there is no reliable evidence that indicates the LD50 to be in the range of Category 5 values (GHS criteria not met).
Acute toxicity (Inhalation)
No data available - waiver
Specific target organ toxicity: single exposure (Oral)
The classification criteria according to the CLP and to the GHS as specific target organ toxicant (STOT) – single exposure, oral are not met since no reversible or irreversible adverse health effects were observed immediately or delayed after exposure and no effects were observed at the guidance value (oral).
Specific target organ toxicity: single exposure (Dermal)
The classification criteria according to the CLP and to the GHS as specific target organ toxicant (STOT) – single exposure, dermal are not met since no reversible or irreversible adverse health effects were observed immediately or delayed after exposure and no effects were observed at the guidance value (dermal).
Specific target organ toxicity: single exposure (Inhalation)
No data available - waiver
Aspiration hazard
The substance is not a hydrocarbon and no effects were observed on lungs in oral studies, therefore the criteria for aspiration toxicity according to the CLP and to the GHS are not met.
