EC number: 227-876-9
CAS number: 6021-61-0
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
