Description of key information

Additional information

All endpoints in this chapter were covered by read-across of studies of 1,4-bis[(2-ethyl-6-methylphenyl)amino]anthraquinone. This read-across is justified as both substances have very similar chemical structures, the main physicochemical parameters (vapour pressure, water solubility and dissociation constant) are in the same range and further all available toxicological studies for both substances revealed the same results. Therefore a read-across for other physicochemical, ecotoxicological or toxicological endpoints seems to be justified. More details about the read-across justification are displayed in a detailed document attached to the Annex of the CSR.

Adsorption: The adsorption coefficient (logKoc) of the test item is 6.2, measured at 25 °C and pH 6.

Henry's Law constant: Data is neither required nor available.
