Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Annex X, Section 9.5.1, of Regulation (EC) No 1907/2006, it is laid down that chronic tests on sediment organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on sediment organisms.  According to Annex I of this regulation, the chemical safety assessment triggers further action when the substance or the preparation meets the criteria for classification as dangerous according to Directive 67/548/EEC or Regulation EC 1272/2008 or is assessed to be a PBT or vPvB.  The hazard assessment of the substance reveals neither a need to classify the substance as dangerous to the environment, nor is it a PBT or vPvB substance, nor are there any further indications that the substance may be hazardous to the environment. In addition, indirect exposure to sediment is unlikely since the substance is readily biodegradable according to OECD criteria. For substances being considered as „readily biodegradable“, it can be assumed that they will be biologically degraded within the STP-process. If the log Koc and log Kow of the substance are below 3, a low adsorption potential is indicated. In case of dimethyl(propy)amine, the log Koc for the charged molecule (pH 5 to 8) is slightly above 3 and thus indicates a potential for adsorption (log Koc = 3.1; see IUCLID Ch. 5.4.1). Hence, an adsorption to activated sludge, suspended matter or sediment particles is possible, although in case of this substance not very pronounced. Based on the low log Kow and the low estimated BCF values, bioaccumulation in aquatic organisms is not to be expected (see IUCLID Ch. 5.3.1). In special cases, if the substance is not entering the STP-process but is readily biodegradable, it can be assumed that it will be rapidly biological degraded in the surface water. As a consequence, a transfer to the sediment compartment is rather unlikely. Therefore, no tests on sediment organisms are provided.
