Data for Component: 4,4' -Methylenediphenyl diisocyanate
Movement & Partitioning
In the aquatic and terrestrial environment, movement is expected to be limited by its reaction
with water forming predominantly insoluble polyureas.
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: N,N'-Dimorpholinodiethylether
Movement & Partitioning
Bioconcentration potential is low (BCF < 100 or Log Pow < 3). Potential for mobility in soil is
very high (Koc between 0 and 50). 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): 3.79E-18 atm*m3/mole; 25 °C Estimated.
Partition coefficient, n-octanol/water (log Pow): -1.31 Estimated.
Partition coefficient, soil organic carbon/water (Koc): 10 Estimated.
Persistence and Degradability
Indirect Photodegradation with OH Radicals
Rate Constant Atmospheric Half-life Method
3.5646E-10 cm3/s 0.03 d Estimated.
Theoretical Oxygen Demand: 2.49 mg/mg
ECOTOXICITY
Data for Component: Isocyanic acid, polymethylenepolyphenylene ester, polymer with
.alpha.,.alpha.',.alpha.''-1,2,3-propanetriyltris[.omega.-hydroxypoly
The measured ecotoxicity is that of the hydrolyzed product, generally under conditions
maximizing production of soluble species. Material is practically non-toxic to aquatic
organisms on an acute basis (LC50/EC50/EL50/LL50 >100 mg/L in the most sensitive species
tested).
Toxicity to Soil Dwelling Organisms
LC50, Earthworm Eisenia foetida, adult, 14 d: > 1,000 mg/kg
Data for Component: Polymethylenepolyphenyl polyisocyanate, polypropyleneglycol copolymer
The measured ecotoxicity is that of the hydrolyzed product, generally under conditions
maximizing production of soluble species. Material is practically non-toxic to aquatic
organisms on an acute basis (LC50/EC50/EL50/LL50 >100 mg/L in the most sensitive species
tested).
Toxicity to Soil Dwelling Organisms
LC50, Earthworm Eisenia foetida, adult, 14 d: > 1,000 mg/kg
Data for Component: Diphenylmethane Diisocyanate, isomers and homologues
The measured ecotoxicity is that of the hydrolyzed product, generally under conditions
maximizing production of soluble species. Material is practically non-toxic to aquatic
organisms on an acute basis (LC50/EC50/EL50/LL50 >100 mg/L in the most sensitive species
tested).
Toxicity to Soil Dwelling Organisms
LC50, Earthworm Eisenia foetida, adult, 14 d: > 1,000 mg/kg
Data for Component: Paraffin waxes and Hydrocarbon waxes, chlorinated
Material is very highly toxic to aquatic organisms on an acute basis (LC50/EC50 <0.1 mg/L in
the most sensitive species).
Fish Acute & Prolonged Toxicity
