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: Tris(1-chloro-2-propyl) phosphate
Movement & Partitioning
Bioconcentration potential is low (BCF < 100 or Log Pow < 3). Potential for mobility in soil is
low (Koc between 500 and 2000).
Henry's Law Constant (H): < 1.35E-5 atm*m3/mole; 25 °C Estimated
Partition coefficient, n-octanol/water (log Pow): 2.59 Measured
Partition coefficient, soil organic carbon/water (Koc): 1,300 Estimated
Bioconcentration Factor (BCF): 0.8 - 4.6; common carp (Cyprinus carpio); Measured
Persistence and Degradability
Material is expected to biodegrade only very slowly (in the environment). Fails to pass
OECD/EEC tests for ready biodegradability.

Theoretical Oxygen Demand: 1.17 mg/mg
Data for Component: Paraffin waxes and Hydrocarbon waxes, chlorinated
Movement & Partitioning
Bioconcentration potential is low (BCF less than 100 or log Pow greater than 7). 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): 7.4 Estimated
Partition coefficient, soil organic carbon/water (Koc): > 5,000 Estimated
Persistence and Degradability
Expected to degrade only slowly in the environment.
Theoretical Oxygen Demand: 2.89 mg/mg
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
