Description of key information
Acute oral toxicity:
In a GLP-compliant oral toxicity study, performed according to OECD guideline 401, Wistar rats (5/sex/dose) were administered FAT 40400/A at dose of 2000 or 5000 mg/kg bw by oral gavage followed by a 14-day observation period. All animals survived. Only diarrhea was observed in the highest dose group during day one of the observation period. No macroscopical changes were observed. There were no effects on body weights. Based on the observations, the acute oral median lethal dose (LD50) of FAT 40400/Ain rats of both sexes observed for a period of 14 days was greater than 5000 mg/kg bw.
Acute inhalation toxicity:
Currently no study to assess acute inhalation toxicity of Reactive Yellow 181 is available. However, low vapour pressure owing to high melting point (>300 °C), the substance is considered to have low volatility. Synthesis and formulation of this chemical is performed in a closed process; the final product consists of liquid formulation only. 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 liquid formulation, the exposure via inhalation is unlikely. Further, Reactive Yellow 181 was found to be miscible in water (water solubility 332 g/L) and have low log partition coefficient (-10), hence, in the case of dust of the substance entering the respiratory tract, it will be trapped in the mucus and cleared, thereby further limiting the absorption. 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 the above arguments into consideration, low toxicity potential is expected on acute exposure of Reactive Yellow 181 via inhalation route.
Acute dermal toxicity:
In a GLP-compliant dermal toxicity study, performed according to OECD guideline 402, Wistar rats (5/sex) were administered FAT 40400/A at the dose of 2000 mg/kg bw. The test substance was dissolved in water and applied on the skin with a syringe and covered with a semi-occlusive dressing for 24 hours. The treated skin was washed after 24 hours and a 14-day observation period followed. No mortality was observed during this period. Scales and discoloration were observed until termination of the study. No macroscopic findings were noted. Therefore, the acute dermal median lethal dose (LD50) of FAT 40400/A was estimated to be >2000 mg/kg bw.
