- Conclusions:
- The acute oral toxicity of FAT 40210/A in rats of both sexed, observed over a period of 15 days, was estimated to be greater than 5000 mg/kg bw.
- Executive summary:
A key study was performed to determine the oral acute toxicity in rats according to OECD Guideline 401 (Acute Oral Toxicity).
The test article FAT 40210/A was administered to rats of both sexes by oral gavage, at doses from 3000 to 5000 mg/kg bw. The following death rate was observed: 0 % at 3000 mg/kg bw and 10 % at 5000 mg/kg bw. The LOGIT-Model could not be applied to these data. And the acute oral toxicity of FAT 40210/A in rats of both sexed, observed over a period of 15 days, was estimated to be greater than 5000 mg/kg bw, which shall not be classified according to CLP Regulation (Regulation [EC] No. 1272/2008).

Additional information
- Oral toxicity:
FAT 40210 was tested in three acute oral toxicity studies. In the key study, performed according to OECD Guideline 401, the LD50 was determined to be >5000 mg/kg bw. In this study, no mortality was observed at 3000 mg/kg bw, while 10 % mortality was seen with 5000 mg/kg bw.
The outcome of the key study was supported by the supporting studies, as no mortality was seen in these studies even at the highest dose of 5000 mg/kg bw.
- Inhalation toxicity:
Currently no study to assess the acute inhalation toxicity potential of the target chemical, Reactive Black 8, is available. However, the vapour pressure for the target chemical is considered to be low owing to the high melting point, hence it is considered to have low volatility. The low partition coefficient of <-6.29 at 20 °C again point to poor absorption across the respiratory tract. The substance was found to have high water solubility (443 g/L), hence the inhaled dust may be retained within the mucus of the respiratory tract, thereby limiting absorption in the lung. The test item synthesis and spray drying are performed in a closed process; the final product consists of non-dusty granules. In addition, 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 substance was found to have low acute toxicity when tested via oral route. Hence, considering all the above arguments, it is considered that the substance has a low toxicity potential via inhalation route and thus the study on acute inhalation toxicity is being waived.
- Dermal toxicity:
Currently no study to assess acute dermal toxicity of the target chemical, Reactive Black 8, is available. However, the molecular weight of the substance is 1384.8 g/mol, which indicates the substance being too large for dermal absorption. Further, high water solubility (443 g/L) and low partition coefficient (<-6.29), indicate the substance may be too hydrophilic to cross the lipid rich environment of the stratum corneum. Hence, the dermal uptake for the substance is expected to be low. The substance showed low toxicity potential in the available acute oral toxicity studies (LD50>5000 mg/kg bw). Similarly, absence of systemic toxicity in skin irritation as well as sensitization studies, further supports the conclusion that no adverse effects are expected via the dermal route. Further, experience with similar chemical substances has demonstrated that it is very unlikely that toxicity related to the intrinsic properties of the substance only show up upon dermal exposure and not after systemic application. Hence, low toxicity is expected on acute dermal exposure of the target chemical and testing by the dermal route was considered scientifically not necessary.
Justification for classification or non-classification
- Oral toxicity:
Based on the above stated assessment of the acute oral toxicity of Reactive Black 8 the substance does not need to be classified according to Council Directive 2001/59/EC (28th ATP of Directive 67/548/EEC) and according CLP (Regulation (EC) No 1272/2008 Of The European Parliament And Of The Council) as implementation of UN-GHS in the EU.
- Dermal toxicity:
As no local or systemic effects were noted in local irritation studies in rabbits the substance does not need to be classified according to Council Directive 2001/59/EC (28th ATP of Directive 67/548/EEC) and according CLP (Regulation (EC) No 1272/2008 Of The European Parliament And Of The Council) as implementation of UN-GHS in the EU.
- Inhalation toxicity:
Due to the very low vapour pressure of the substance and the fact that the substance is formulated as a dust-free powder or granulate the inhalation route of exposure is considered to be unlikely. Therefore, no classification for acute inhalation toxicity is deemed necessary according to Council Directive 2001/59/EC (28th ATP of Directive 67/548/EEC) and according CLP (Regulation (EC) No 1272/2008 Of The European Parliament And Of The Council) as implementation of UN-GHS in the EU.
