Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The tested multiconstituent substance belongs to a category of substances consisting of similar composition. Starting substance for all group members is Propylidynetrimethanol which is ethoxylated and/or propoxylated to different magnitudes and - for some of the substances - gets modified with an amine compound. A more detailed description of the group is attached to section 13 of this dossier. Due to the multiconstituent nature of the test substance a representative structure was used in order to calculate a representative log Koc value. The log Koc values of the test substance was calculated to be 5.1 using EPI Win v4.10 (BASF SE, 2013). This log Koc value indicates that the components of this multiconstituent substance will bind to soils and sediments.
