Description of key information

The water solubility of the registered substance PR 264 is considered to be < 0.1 mg/L. Therefore, PR 254 is considered insoluble in water.

Key value for chemical safety assessment

Additional information

A study in a NONS-file provided by ECHA, which is therefore considered reliable, reports a water solubility of < 0.4 mg/L.

In addition, using a method specifically developed for pigments ('ETAD-method'), the log kow of the registered substance PR 264 has been determined by the ratio of the solubilities in octanol (0.252 mg/L) and in water (0.048 mg/L). Therefore, PR 254 is considered insoluble in water.
