Description of key information

A study for determining the stability of C.I. Direct Blue 264 regarding hydrolysis is technically not feasible. But under consideration of the chromatograms received during the study of water solubility over a period of 34 days, it can be assumed that C.I. Direct Blue 264 is stable in the aquatic environment and abiotic degradation can be excluded. 

Key value for chemical safety assessment
