- Conclusions:
- Based on the results of acute dermal toxicity test, LD50 (rat, dermal) of the test substance is estimated to be greater than 2000 mg/kg bw.
- Executive summary:
The purpose of this study was to assess the acute dermal toxicity of FAT 40'549/A when administered to rats by a single semi-occlusive dermal application, followed by an observation period of 14 days.
The study procedures described in this report are based on OECD Guidelines for Testing of Chemicals, Section 4, Number 402 "Acute Dermal Toxicity", adopted February 24, 1987 and Directive 92/69/EEC, B.3. "Acute Toxicity-Dermal", July 31, 1992.
The test substance was applied to the skin of Wister rats of both sexes for 24 hrs at a dose of 2000 mg/kg bw. No mortality was observed at test concentration. No deviation from normal morphology at necropsy. The body weight gain of the animals was within the normal range for rats of this strain and age.
Therefore, the LD50 of test substance was estimated to be greater than 2000 mg/kg bw, which indicates that test substance is "not classified" in accordance with CLP (Regulaton EC No. 1272/2008) for acute dermal toxicity.

Additional information
Acute oral: The test substance was administered to a group of 5 male and 5 female rats by oral gavage, at a single dose of 2000 mg test article/kg body weight. The test was performed according to OECD TG 401. There were no deaths as a result of treatment with the test article. No clinical signs of toxicity were observed during the observation period and the body weight of the animals was within the normal range for rats of this strain and age. No organ abnormalities were observed at necropsy. Thus, LD50 oral was greater than 2000 mg//kg bw based on the test results.
Acute dermal: The test substance was applied to the skin of rats of both sexes for 24 hrs at a dose of 2000 mg/kg bw to access the acute toxicity. No mortality was observed at test concentration. No deviation from normal morphology at necropsy. The body weight gain of the animals was within the normal range for rats of this strain and age. Therefore, the LD50 of test substance was estimated to be greater than 2000 mg/kg bw.
Acute inhalation: Currently no study to assess the acute inhalation toxicity potential of Reactive Yellow 205 is available. The calculated value for vapour pressure was found to be <2.2E-27 Pa at 25 °C. Hence the substance is considered to have low volatility. Synthesis and spray drying 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. Further the water solubility of test substance was found to be greater than 385 g/L, 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 toxicity study (LD50: >2000 mg/kg bw), with no systemic toxicity being seen, hence it does not need to be classified STOT SE and low toxicity is expected for this chemical via the inhalation route. Taking into consideration the above arguments, low toxicity potential is expected on acute exposure of Reactive Yellow via inhalation route and hence testing by the inhalation route was considered scientifically not necessary. In addition to the oral route, for substances other than gases, the information of inhalation and dermal route shall be provided for at least one other route. The inhalation toxicity test can be waived as acute oral and dermal toxicity tests were performed.
Justification for selection of
acute toxicity – oral endpoint
OECD guidance test with GLP compliance
Justification for selection of acute toxicity – dermal endpoint
OECD guidance test with GLP compliance
Justification for classification or non-classification
Based on study results, the test substance is not classified for acute oral and dermal toxicity in accordance with CLP (Regulation EC No. 1272/2008) or DSD (Directive 67/548/EEC). In addition no systemic toxicity effects were seen in the acute studies performed and thus also classification for specific target organ toxicity, single exposure is not required.
Data for acute inhalation toxicity are lacking.
