Lung tumors have been observed in laboratory animals exposed to respirable aerosol droplets of
MDI/Polymeric MDI (6 mg/m3) for their lifetime. Tumors occurred concurrently with respiratory
irritation and lung injury. Current exposure guidelines are expected to protect against these effects
reported for MDI.
Developmental Toxicity
In laboratory animals, MDI/polymeric MDI did not cause birth defects; other fetal effects occurred only
at high doses which were toxic to the mother.
Reproductive Toxicity
No relevant information found.
Genetic Toxicology
In vitro genetic toxicity studies were negative for component(s) tested. Genetic toxicity data on MDI
are inconclusive. MDI was weakly positive in some in vitro studies; other in vitro studies were negative.
Animal mutagenicity studies were predominantly negative.
12. Ecological Information
ENVIRONMENTAL FATE
Data for Component: Isocyanic acid, polymethylenepolyphenylene ester, polymer with
.alpha.,.alpha.',.alpha.''-1,2,3-propanetriyltris[.omega.-hydroxypoly
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: Polymethylenepolyphenyl polyisocyanate, polypropyleneglycol copolymer
Movement & Partitioning
In the aquatic and terrestrial environment, movement is expected to be limited by its reaction
with water forming predominantly insoluble polyureas.

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.
