Additional information

Studies for all three trophic levels are available (fish, daphnia, algae) and no effect was determined up to the highest test item concentration of 100 mg/L in each study. Furthermore, the substance has a low predicted log Kow of 2.7.

Conclusion on classification

No effects in aquatic studies and the rapid hydrolysis to inert and insoluble oligo- and polyureas indicate that the substance shows no hazard to aquatic life. No classification is needed.
