Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to Column 2 of REACH annex X the test if the results of the chemical safety assessment indicates no need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms.

The substance is very poorly soluble in water and readily biodegradable. The equilibrium partitioning method, following a fugacity model III indicate a partition of the substance on sediments of 85.5%, based on high Kow.

But based on results of bacteria inhibition and biodegradability, it is not previewd a toxicity effect on sediment organisms.

A tier 1 Risk Assessment based on the European main use of the substance elaborated with EUSES 2.0 showed no concern; it is assumed that water exposure will not occur because the exposure scenarios is focused only on industrial application where all waste, when present, is sent to STP, where a 100% of degradation occurs.
