Additional information
Conclusion on classification
Classification and labelling according to aquatic toxicity data
Justification for classification or non classification
Three acute tests have been performed with fish, daphnia and algae. No effects have been observed up to the concentrations of 100 mg/l. Therefore, a classification related to risk phrases H400, H410, H411, H412 or R50, 51, 52 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 5.9. However, when dissoolved using a modifier,the substance hydrolysis rapidly with a half life of 2 days. The hydrolysis products are mainly insoluble oligomeric and polymeric ureas which are essentially insoluble. Therefore, a classification related to risk phrase H413 or R53 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.
