Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.  No information concerning effects on sediment-organisms is available for 1,4-dioxane (CAS 123-91-1). However, the available data indicate that the substance is not very adsorptive (log Koc < 3; see IUCLID chapter 5.4.1) or bioaccumulative (mean BCF = 0.45; measured, see IUCLID chapter 5.3.1). Furthermore, the substance’s distribution modelling indicates that the main target for environmental distribution will be water (see IUCLID chapters 5.4.3). Therefore, a relevant distribution into the sediment compartment and a considerable exposure of sediment organisms is not expected. Consequently, no test on sediment organisms is performed.
