ECOTOXICITY
Data for Component: Diphenylmethane-4,4'-diisocyanate (MDI), isomers(1) and homologues(2),
blending of (1) and (2)
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 >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: 4,4' -Methylenediphenyl diisocyanate
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 >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: 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 >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 practically non-toxic to fish on an acute basis (LC50 > 100 mg/L). Material is very
highly toxic to aquatic invertebrates on an acute basis (LC50/EC50 < 0.1 mg/L).
Fish Acute & Prolonged Toxicity
LC50, rainbow trout (Oncorhynchus mykiss), static, 96 h: > 100 mg/l
Aquatic Invertebrate Acute Toxicity

Data for Component: Propane
No relevant information found.
Data for Component: Methyl ether
Material is practically non-toxic to aquatic organisms on an acute basis (LC50/EC50 >100
mg/L in the most sensitive species tested).
Fish Acute & Prolonged Toxicity
LC50, guppy (Poecilia reticulata), 96 h: > 4,000 mg/l
Aquatic Invertebrate Acute Toxicity
