Description of key information
Additional information
Stability:
Alcohols, C8-10-iso, C9-rich has 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 8.8 hours).
Aliphatic alcohols 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:
Alcohols, C8-10-iso, C9-rich, is expected to be readily biodegradable (98% in 28 days) based on aerobic biodegradation studies using standard OECD test guidelines. Therefore, biotic degradation will significantly contribute to the loss of this substance from the environment.
Bioaccumulation:
Experimental data for an analogue substance along with the biochemical evidence suggest that this substance has a very low potential for bioconcentration in aquatic species and is not expected to bioaccumulate.
Transport and distribution:
Soil adsorption of Alcohols, C8-10-iso, C9-rich is expected to occur to a moderate degree (log Koc = 2.45).
Henry's Law constant (6.54 Pa.m3/mole) indicates that volatilization from water is not expected to occur at a rapid rate, but may occur at a significant rate.
Distribution modeling estimates that Alcohols, C8 -10 -iso, C9 -rich will partition largely to the soil compartment (ca. 68%), followed by the water (ca. 30%), and minimally to air (ca. 2.1%), and sediment (0.1%) compartments.
