Description of key information
Additional information
Based on the available information Benzoguanamine should be considered as relatively stable under environmental conditions. Due to the low vapour pressure exposure of the atmosphere can be neglected. As data for photodegradation neither in soil nor in water are available hydrolysis is the only evaluated abiotic degradation pathway. The presented OECD study gave clear indication that Benzoguanamine has to be considered as hydrolytically stable under environmental conditions.
In addition, analysis of biotic degradation showed that Benzoguanamine is not readily biodegradable. However, estimations by QSAR calculation gave indication on an ultimate biodegradation within a timeframe of weeks to months.
The simulation study in surface water was conducted at 12 °C and showed no relevant degradation within the timeframe of 60 days.
As no kinetic parameter could be calculated from the results an unlimited half-life for persistent substances (default) in water is assumed. Based on the available information on the fate of Benzoguanamine the substance is considered to fulfill the "very persistent" criteria of Annex XIII of REACH.
QSAR estimations on the potential for bioaccumulation gave clear indication that bioaccumulation of Benzoguanamine within animals, respectively the food chain, is highly unlikely. For this reason further testing on bioaccumulation in fish has not been proposed in accordance with Annex IX of REACH Regulation.
Analysis of the transport and distribution behaviour of Benzoguanamine by OECD studies on the n-octanol/water partition coefficient as well as the adsorption coefficient showed that the substance is very mobile and is not likely to adsorb to soil nor sediment. Based on these results and the foreseeable conditions of use exposure of soil and sediment is expected to be negligible. This was also supported by two level-III-simulation of the distribution of Benzoguanamine in the different environmental compartments and the screening assessment for both compartments using the EP method.
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.
