Conclusion on classification

For the 3 trophic levels (fish, invertebrates and algae) several studies on the short-term toxicity are available which all show the lack of toxicity of the substance on the tested aquatic organisms at its saturation concentration.

Screening test on biodegradation indicate that the substance is not readily biodegradable. And with a log Kow of 3.1 the substance is not considered as bioaccumulable.

Taking into account the above properties, the substance is not classified for the environnement according to the CLP criteria.
