Conclusion on classification
Classification and labelling according to aquatic toxicity data
Justification for classification or non-classification
Three acute and three chronic tests have been performed with fish, daphnia and algae. No effects have been observed up to the concentrations of 100 mg/L and 10 mg/L, respectively. Therefore, a classification related to hazard phrases H400, H410, H411, H412 can be ruled out.
Classification and labelling according to degradation and bioconcentration
Justification for classification or non-classification
The substance is not readily biodegradable and has a logPow of 6.7 (calculated). However, the substance hydrolysis rapidly with a half-life of 2 hours. The hydrolysis products are oligomeric and polymeric ureas which are considered to be not bioavailable due to their high molecular weight of >1800 D. Therefore, a classification related to hazard phrase H413 is not required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
