Description of key information

Additional information

The substance is not expected to significantly hydrolyze at environmental conditions.

The only group possibly susceptible to hydrolysis is the amide group which has half-lives measured in centuries at pH 7 (Mabey and Mill 1978). Moreover the molecule is fully conjugated and therefore a hydrolytically sensitive amide group is not present in the molecule anymore.

The substance is expected to be persistent or even very persistent in the environment. It is a pigment which are generally not biodegradable.

The substance is not expected to significatnly bioaccumulate in organisms. Its logKow is << 3 and therefore any potential to bioaccumulate can be ruled out.

Due to the low logKow (<<3) the substance is not expected to have any adsorption potential.
