Additional information
Acute toxicity, oral:
In a GLP-compliant oral toxicity study, performed according to OECD guideline 401 and EU method B.1, Wistar rats (5/sex) were administered FAT 40224/C (5000 mg/kg bw) by oral gavage followed by a 14-day observation period. Mortality was not observed. Symptoms observed were sedation, dyspnea and ruffled fur. All rats had recovered after 2 observation days. At necropsy 1 male showed several red foci in the lung (1 mm) and 1 male showed partly red foci in the lung (1mm). The acute oral toxicity (LD50) of the test substance in rats of both sexes, observed over a period of 14 days, was estimated to be: greater than 5000 mg/kg bw.
Acute toxicity, inhalation:
Currently no study to assess acute inhalation toxicity of Reactive Yellow 174 is available. However, low vapour pressure owing to high melting point (>300 °C), the substance is considered to have low volatility. Synthesis of this chemical is performed in a closed process; the final product consists of non-dusty granules. Hence, the use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalation route will be unlikely to occur. Based on column 2, ‘Specific rules for adaptation from column 1’ of the table given in REACH Annex VII, the study on acute inhalation toxicity only needs to be conducted if an exposure via inhalation is to be expected, based on the likelihood of an exposure to aerosols, particles or droplets. Referring to the expected low volatility of the substance, the fact that the substance is imported into the EU in a formulated form as a dust-free powder or as a granulate, the exposure via inhalation is unlikely. The chemical showed low toxicity potential in the available acute oral (LD50 >5000 mg/kg bw) and acute dermal (LD50 >2000 mg/kg bw) with no mortality or systemic toxicity, hence, it does not need to be classified as STOT SE. Taking into consideration the above arguments, low toxicity potential is expected on acute exposure of Reactive Yellow 174 via inhalation route.
Acute toxicity, dermal:
In a GLP-compliant dermal toxicity study, performed according to OECD guideline 402, Wistar rats (5/sex) were administered FAT 40224/C (2000 mg/kg bw). The test substance was dissolved in 4 % CMC in distilled water and applied on the skin with a syringe and covered with an occlusive dressing for 24 hours. The treated skin was washed after 24 h and a 14-day observation period followed. No mortality was observed during this period. The following symptoms were observed: Emaciation (females) and the application area was discolored. Discoloration of the treated skin was observed until termination of observation. So, based on the study results, the dermal median lethal dose (LD50) of the test substance was estimated to be greater than 2000 mg/kg bw.
Justification for classification or non-classification
Based on the observed LD50 of >5000 mg/kg bw and >2000 mg/kg bw in the acute oral and dermal toxicity study, the test substance does not considered to be classified according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
