EC50, Eisenia fetida (earthworms), 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/EL50/LL50 >100 mg/L in the most sensitive species
tested).
Fish Acute & Prolonged Toxicity
Based on information for a similar material: LC50, Danio rerio (zebra fish), static test, 96 h: >
1,000 mg/l
Aquatic Invertebrate Acute Toxicity
Based on information for a similar material: EC50, Daphnia magna (Water flea), static test, 24

Aquatic Plant Toxicity
Based on information for a similar material: NOEC, Desmodesmus subspicatus (green algae),
static test, Growth rate inhibition, 72 h: 1,640 mg/l
Toxicity to Micro-organisms
Based on information for a similar material: EC50, activated sludge test (OECD 209),
Respiration inhibition, 3 h: > 100 mg/l
Toxicity to Soil Dwelling Organisms
EC50, Eisenia fetida (earthworms), 14 d: > 1,000 mg/kg
Data for Component: 1,1,1,2-Tetrafluoroethane

Persistence and Degradability
Data for Component: Diphenylmethane Diisocyanate, isomers and homologues
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.
