Persistence and Degradability
In the aquatic and terrestrial environment, material reacts with water forming predominantly
insoluble polyureas which appear to be stable. In the atmospheric environment, material is
expected to have a short tropospheric half-life, based on calculations and by analogy with
related diisocyanates.
Data for Component: Paraffin waxes and Hydrocarbon waxes, chlorinated
Movement & Partitioning
Expected to be relatively immobile in soil (Koc > 5000). Given its very low Henry's constant,
volatilization from natural bodies of water or moist soil is not expected to be an important fate
process.
Henry's Law Constant (H): < 1.0E-07 atm*m3/mole; 25 °C Estimated
Partition coefficient, n-octanol/water (log Pow): > 6 Estimated
Persistence and Degradability
Expected to degrade only slowly in the environment.
Data for Component: Isobutane
Movement & Partitioning
Bioconcentration potential is low (BCF less than 100 or log Pow less than 3). Potential for
mobility in soil is very high (Koc between 0 and 50).
Henry's Law Constant (H): 1.19E+00 atm*m3/mole; 25 °C Measured
Partition coefficient, n-octanol/water (log Pow): 2.76 Measured
