Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Exposure to organisms via sediment is very unlikely since the test item does not distribute into sediment with high probability. Therefore, no testing on sediment organisms is required.

Key value for chemical safety assessment

Additional information

The test item is highly soluble in water (~550 g/L, c.f. 4.8.) and is readily biodegradable (Frauenhofer IME, 2011) therefore an exposure via sediment is not expected. This is underlined by valid Mackay Level I distribution modelling (BASF, 2008). According to this calculation sediment is not a target compartment of the test item. When released into the environment 98.8 % will remain in the water phase and 1,16 % will evaporate to the air (see table 1). In order to this, a distribution to soil and sediment is not expected. In addition, the test item has a low log Kow (0.35, Hansch et al., 1995) and does not tend to bioaccumulate in organisms.


In conclusion, exposure of sediment organisms is very unlikely and further experimental studies won’t reveal new findings with a high probability.
