Description of key information

Additional information

Stability:


The registered substance is comprised of constituents with the potential to degrade in the atmosphere from hydroxyl radical attack and photodegradation can be a predominant daylight atmospheric degradation process for this substance (half-life <10 hours). The registered substance is a UVCB that does not contain constituents that possess a hydrolytically reactive functional group; thus are resistant to hydrolysis, and will not undergo direct photolysis in water and soil. As such, these fate processes will not contribute to a measurable loss of this substance from the environment.


Biodegradation:


The registered substance is expected to be ultimately biodegradable based on aerobic biodegradation studies using standard OECD test guidelines (62% in 49 days) and is not expected to be persistent. Therefore, biotic degradation will significantly contribute to the loss of this substance from the environment.  


Bioaccumulation:


The registered substance is expected to have a low to moderate potential for bioconcentration in aquatic species (calculated BCF values <2000).  


Transport and distribution:


Soil adsorption is expected to occur at a moderate to high degree (log Koc = 3.9 to 6.9). Henry's Law constant (3 to >1000 Pa.m3/mole for major constituents) indicates that volatilization from water is expected to occur at a moderate to rapid rate.
