- Executive summary:
In a GLP-compliant oral toxicity study, performed according to OECD guideline 423, Wistar rats (2 groups of 3 females) were administered the test substance (2000 mg/kg bw) by oral gavage followed by a 14-day observation period. All animals survived until the end of the study period and no changes in body weights and macroscopic findings were observed. The only clinical signs observed, were slightly ruffled fur with hunched posture in all animals of the first treated group at the 2- and 3-hour reading and slightly ruffled fur in two animals of the second treated group from the 1- to 3-hour reading which persisted in one animal up to the 5-hour reading. Hunched posture was noted in the same animals at the 2- and 3-hour reading. Red soft faeces were present in the cage between the 1- and 5-hour reading of the first treated group and were also noted on test day 2. Red discoloration of the softwood bedding was also noted between the 2-hour reading and test day 2. Red faeces as well as red discoloration of the softwood bedding was also noted in the cage of the second treated group at the 1-hour reading and red soft faeces with red discoloration of the softwood bedding was noted up to test day 2. Slight sedation was noted in one animal from the 1- to the 3-hour reading and slight ataxia was noted in the same animal from the 2- to the 5-hour reading of the second treated group. Based on the observations, the median lethal dose of the test substance in female rats observed for a period of 14 days was greater than 2000 mg/kg bw.

- One day before treatment, the backs of the animals were clipped with an electric clipper, exposing an area of approximately 10% of the total body surface. Only those animals without injury or irritation on the skin were used in the test. On test day 1, the test item was applied at a dose of 2000 mg/kg body weight evenly on the intact skin with a syringe and covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and fixed with an elastic adhesive bandage.
Application volume/kg body weight: 4 mL.
24 hours after the application the dressing was removed and the skin was flushed with lukewarm tap water and dried with disposable paper towels. Thereafter, the reaction sites were assessed. The fur of all animals was shaved on test day 9 just after the assessment of the reaction to facilitate the skin reading for the next day. - Duration of exposure:

Additional information
Acute toxicity, oral:
In a GLP-compliant oral toxicity study, performed according to OECD guideline 423, Wistar rats (2 groups of 3 females) were administered the test substance (2000 mg/kg bw) by oral gavage followed by a 14-day observation period (RCC 2005). All animals survived until the end of the study period and no changes in body weights and macroscopic findings were observed. The only clinical signs observed, were slightly ruffled fur with hunched posture in all animals of the first treated group at the 2- and 3 -hour reading and slightly ruffled fur in two animals of the second treated group from the 1- to 3- hour reading which persisted in one animal up to the 5-hour reading. Hunched posture was noted in the same animals at the 2- and 3-hour reading. Red soft faeces were present in the cage between the 1- and 5-hour reading of the first treated group and were also noted on test day 2. Red discoloration of the softwood bedding was also noted between the 2-hour reading and test day 2. Red faeces as well as red discoloration of the softwood bedding was also noted in the cage of the second treated group at the 1-hour reading and red soft faeces with red discoloration of the softwood bedding was noted up to test day 2. Slight sedation was noted in one animal from the 1- to the 3-hour reading and slight ataxia was noted in the same animal from the 2- to the 5-hour reading of the second treated group. Based on the observations, the median lethal dose of the test substance in female rats observed for a period of 14 days was greater than 2000 mg/kg bw.
Acute toxicity, dermal:
In a GLP-compliant dermal toxicity study, performed according to OECD guideline 402, Wistar rats (5/sex) were treated with the test substance (2000 mg/kg bw) by dermal application (RCC 2005). The test substance was diluted in vehicle (polyethylene glycol), administered on the skin with a syringe and covered with a semi-occlusive dressing for 24 hours. After 24 hours the dressing was removed and the skin was flushed with lukewarm tap water. A 14-day observation period followed. No deaths occurred during the study and the body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were observed. Ruffled fur was noted at the 3-hour reading in three male animals and was persistent up to the 5-hour reading in two animals. Red discoloration of the treated skin area produced by the test item prevent the assessment of a possible erythema in all male animals on test days 2-4 and again on test days 7 to 13, or test days 9 or 10 to the end of the observation period. Slight crusts were noted on test days 2 to 5, 8 or 15. Red discoloration of the treated skin area produced by the test item prevent the assessment of a possible erythema in all female animals on test days 2- 4 and again from test day 6, 9 or 12 to the end of the observation period. Slight crusts were noted on test days 2 or 4 to 6, 8, 9 or 15. Based on the observations, the toxicity of the test substance is greater than 2000 mg/kg bw.
Acute toxicity, inhalation - waiver
Currently no study to assess the acute inhalation toxicity potential of Reactive Red 280 is available. The calculated value for vapour pressure was found to be 2.19E-31 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. 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 vapour pressure and/or the likelihood of an exposure to aerosols, particles or droplets. Referring to the expected low volatility of the substance, the fact that the chemical is imported into the EU in a formulated form as a dust-free powder or as a granulate, the exposure via inhalation is considered to be unlikely. Further, the chemical is found to have water solubility of at least 337 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 (LD50: >2000 mg/kg bw) and dermal (LD50: >2000 mg/kg bw) toxicity studies, 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 the above arguments into consideration, low toxicity potential is expected on acute exposure of Reactive Red 280 via inhalation route and hence testing by the inhalation route was considered scientifically not necessary.
Justification for classification or non-classification
Based on the observed LD50 of >2000 mg/kg bw in the acute oral and dermal toxicity study, the test substance does not need to be classified according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
