Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Reference substance:
- Reaction mass of 4,4'-methylenediphenyl diisocyanate and Amines, soya alkyl - Boundary composition
- Reference substance:
- Reaction mass of 4,4'-methylenediphenyl diisocyanate and Amines, soya alkyl - Boundary composition
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance is not readily biodegradable, based on QSAR estimates for biodegradation conducted using BIOWIN (US EPA 2010) and the data available on MDI category substances. A persistence screening assessment according to ECHA guidance has been performed, and was unable to draw a definitive conclusion on the persistence of the substance based on the currently available information. The assessment is summarised in the report “PBT Screening Assessment” which is attached to the additional information section of the endpoint summary.
The BCF screening calculations indicate that this substance is not expected to be bioaccumulative based on Log Kow and BCF predictions. The low water solubility and high molecular weight of the constituents of the substance indicate that they are unlikely to be taken up by organisms. The substance showed no acute or chronic toxicity to aquatic organisms at loading rates up to 100 mg/L. This substance is not carcinogenic, mutagenic or toxic for reproduction and data indicate that chronic toxicity and repeat dose specific target organ toxicity is not expected. This substance is thus considered not to be toxic. Therefore, it is considered not to meet the criteria for PBT/vPvB.
