Rats were caged singly and kept in a room maintained at a temperature of 21 °C (+/-2°). Animals were subjected to 12 hours artificial light and 12 hours darkness in each 24 hour period. A commercial pelleted diet (Oakes Special Diet with added Vit. E) was fed ad lib. Water was available at all times. - Route of administration:

A 25 % w/v suspension of the compound in a 2 % aqueous solution of Carboxymethyl Cellulose was administered as a single dose by gavage to rats which had been fasted for 10 hours, at a dose rate of 20ml/kg. (Equivalent to 5 g/kg compound). - Doses:

- No deaths occurred during the 14 days observation period.
- Clinical signs:
- other: No clinical symptoms were recorded during the 14 days observation period.
- Gross pathology:
- At autopsy no changes in organs or tissues causes by the administration of the test compound were seen.
- Other findings:
- None
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral median lethal dose (LD50) of FAT 20085/A in rats (both sexes) is >5000 mg/kg body weight.
- Executive summary:
The acute oral toxicity of FAT 20085/A was evaluated in a study conducted according to the methodology similar to OECD Guideline 401. In this study, the test article FAT 20085/A was administered as a single dose by oral gavage to rats of both sexes, at a dose of 5000 mg/kg bw in a solution of Carboxymethyl Cellulose. No deaths or clinical signs were observed during the 14-days observation period. At autopsy no changes in organs or tissues caused by the administration of the test compound were seen. Hence, the acute oral toxicity (LD50) of FAT 20085/A in rats of both sexes, observed over a period of 14 days, was estimated to be >5000 mg/kg bw.

Additional information
Oral:
The acute oral toxicity of FAT 20085/A was evaluated in a study conducted according to the methodology similar to OECD Guideline 401. In this study, the test article FAT 20085/A was administered as a single dose by oral gavage to rats of both sexes, at a dose of 5000 mg/kg bw in a solution of Carboxymethyl Cellulose. No deaths or clinical signs were observed during the 14-days observation period. At autopsy no changes in organs or tissues caused by the administration of the test compound were seen. Hence, the acute oral toxicity (LD50) of FAT 20085/A in rats of both sexes, observed over a period of 14 days, was estimated to be >5000 mg/kg bw.
Inhalation:
Currently no study to assess the acute inhalation toxicity potential of ACID BLUE 090 is available. The vapour pressure forthe substance was determined to be 9.34x10E-2 Pa. Hence the substance is considered to have low volatility. Owing to this, 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. The water solubility of ACID BLUE 090 was determined to be 171 g/L,hence the dust if inhaled may be retained within the mucus, thereby further limiting the reach to the lower respiratory tract. Further, no systemic toxicity or mortality were observed in the acute oral toxicity studies withACID BLUE 090. Taking into consideration above information, acute inhalation exposure is considered to have negligible potential for systemic toxicity. Therefore testing by the inhalation route was considered scientifically not necessary and the intrinsic property/toxicity potential can be extrapolated from the acute oral toxicity study.
Dermal:
Currently no study to assess acute dermal toxicity of ACID BLUE 090 is available. However, the molecular weight of the substance is 854 g/mol, which indicates substance is too large for dermal absorption. Further, owing to high water solubility (171 g/L) and low partition coefficient (-2.55), the substance is considered to be too hydrophilic to cross the lipid rich environment of the stratum corneum and hence the dermal uptake for the substance is expected to be low. Further, no systemic toxicity or mortality were observed in the acute oral toxicity study with ACID BLUE 090. Hence, potential for occurrence of systemic toxic effects subsequent to dermal exposure is considered to be unlikely to occur. Similarly absence of systemic toxicity or mortality in skin irritation as well as sensitization studies, further supports the conclusion that no adverse effects are expected via dermal exposure. 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 further experiments to assess dermal toxicity are not taken into account.
Justification for classification or non-classification
Acid Blue 090 was found to be not acute toxic up to the dose 2000 mg/kg bw, hence it does not warrant classification as per the criteria of Regulation (EC) No. 1272/2008 (CLP).
