Additional information

Members of this category do not contain any hydrolysable functional groups, so will not undergo hydrolysis. Category members with carbon numbers from C6 to C24 have been shown to be readily biodegradable in biodegradation screening tests. Due to this, the simulation tests on degradation in water, soil and sediment are not required for these substances as they not expected to persist in the aquatic or terrestrial environment. Category members with carbon numbers of C26 and above are not considered to be readily biodegradable.

Log BCFs have been calculated on the basis of the measured or calculated log Kow using two different QSARs that are appropriate for members of this category. When the log Kow was outside the QSAR domain results have been read across from category members based on the observed trend in log BCF. Log Koc have also been calculated on the basis of the measured or calculated log Kow using a QSAR that is appropriate for members of this category. When the log Kow was outside the QSAR domain results have been read across from category members based on the observed trend in calculated log Koc.
