Additional information

According to the Annex VII of the REACH Regulation, the study does not need to be conducted if, based on the physicochemical properties, the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient).

Basic Orange 064 has a logPow of -4.36 at 20 °C and pH 4.2 - 4.3.

However, a computed value of 3.16 l/kg by EUSES 2.1.2 software was reported.
