Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

log Koc: <3 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

Studies investigating the adsorption/desorption behaviour of 6-methyl-2-oxoperhydropyrimidin-4-yl urea are not available. The soil sorption coefficient Koc of the substance was calculated using PCKOCWIN v2.00. A log Koc of 0.098 based on log Pow was calculated. Thus adsorption of the substance to soil and suspended matter is not expected.
