EC number: 701-173-1
CAS number: -
A structurally related analogue was found to be non biodegradable in a biodegradation test according to OECD Guideline 302C (Caspers et al, 1986). There was 0% biodegradation found after 28 days.
A biodegradation screening test in water is available for the
structurally related analogue PMDI. According to OECD Guideline 302C
(Inherent biodegradability: Modified MITI Test (II)) 0% biodegradation
was found after 28 days based on oxygen consumption under aerobic
condtions with domestic sewage (adaptation not specified).
MDI hydrolyses very rapidly in water. Hence, this test measured the
biodegradation of the hydrolysis products of PMDI. Based on the
justification in the category approach, it is assumed that all MDI
analogues included in the category are not readily biodegradable.
