Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
After evaporation or exposure to the air, the product will be rapidly degraded by photochemical processes.
Key value for chemical safety assessment
- Half-life in air:
- 0.1 d
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 half-life in air. For this calculation a 24-hour day as well as a sensitizer-concentration (OH-radicals) of 500000 molecules/cm³ were assumed. The calculated rate constant of 197E-12 cm³/molecule-sec results in a half-life in the atmosphere of approx. 0.1 days (BASF SE 2012).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
