Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

In accordance with column 2 of REACH Regulation No. 1907/2006 EEC, Annex VIII, Sect., col. 2 the hydrolysis as a function of pH test can be waived, if the substance is readily biodegradable or highly insoluble in water. Urea 6 is insoluble in water (< 1 mg/L). Therefore, determination of hydrolysis as a function of pH is scientifically unjustified and not required.

The ready biodegradability of the test item was assessed over a 28 day period. The test material attained 14.25 % biodegradation after 28 days. Thus, the test item was classified not readily biodegradable under the conditions of the test.

The bioaccumulation potential of Urea 6 was assessed in a flow–through fish test using the model substance Tolyl bis urea compound, as agreed between The German Federal Environmental Agency (Umweltbundesamt), Klüber Lubrication and SCC GmbH. This decision was confirmed by the Federal Institute for Occupational Safety and Health (BAuA) on the 26th of April in 2008 (letter attached). Fish were exposed for 10 days to diet treated with 1 g/kg test item. The 10 days uptake phase was followed by a 6 days depuration phase. The test demonstrates that the test item has no bioaccumulation potential.

In accordance with column 2 of REACH Regulation No. 1907/2006 EEC, Annex VIII, Sect. 9.3.1, col. 2 adsorption/desorption testing can be waived, if due to physical chemical properties of the test item a low adsorption potential is expected. Urea 6 is insoluble in water. Thus, leaching potential of Urea 6 into soil can be excluded. Further, the substance is exclusively synthesised in a matrix and a direct exposure to soil can be excluded.
