Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Additional information

THPC-urea is not readily biodegradable. But according to a 31P-NMR analytical monitored Zahn-Wellens test within 14 days a complete degradation to primary metabolites (THPO) occurs.

Data on the biodegradation in the sediment and soil compartments are not available. The test item hence should be considered as inherent biodegradable.

The substance is hydrolytically stable under neutral and acidic environmental condition but shows a tendency for less stability in basic environments. Photodegradation in air seems not to be a relevant degradation process for this substance since the test item has a negligible vapour pressure. There is no information available about photodegradation of the substance in sediment or soil.

According to the screening criteria for bioaccumulation THPC-urea is not considered to be bioaccumulative. The estimated octanol-water partition coefficient for the substance is very low (log Kow < -2.8) whichsuggests also no potential for adsorption on soil or sediment.
