Description of key information

There is limited information on phototransformation of the test substance in water. It can be concluded that some transformation may occur under influence of light.

Key value for chemical safety assessment

Additional information

The available tests are different from the guidelines and either are not done in water (Freitag 1985) or do not contain calculation of the half-life (Oussy 1988). Therefore no definite conclusion can be drawn.

According to REACH Annex IX section 9.2.2.1 Column 2 this study can be waived if the test substance is readily biodegradable. Therefore as the substance is readily biodegradable, a waiver is justified.
