Description of key information
Disperse Red 054 has a low water solubility of 94 µg/l at 20 °C and a high logPow of 4.03 at 25 °C.
Due to the low solubility in water, Disperse Red 054 is poorly bioavailable to aquatic species and the aquatic compartment is unlikely relevant for toxicity.
Justification for classification
A safety net classification (cat. chronic 4) may apply to cases of poorly soluble substances for which no acute toxicity is expected at levels up to the water solubility and which are not rapidly degradable and have an experimentally determined BCF ≥ 500 (or, if absent, a logPow ≥ 4), indicating a potential to bioaccumulate. Classification in this category occurs unless other scientific evidence exists showing classification to be unnecessary. Such evidence includes chronic toxicity NOECs > water solubility or > 1 mg/l, or other evidence of rapid degradation in the environment than the ones provided by standard methos.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
