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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The vapour pressure was determined with the use of Modified Grain-Watson estimation (MPBPWIN v1.43, Estimation Programs Interface Suite™ for Microsoft® Windows v4.10). It was calculated using the C16 and C18-components of "alcohols, C16-C18, ethoxylated phosphates" (mono- and diester) with EO=0 and EO=3. The QSAR model uses the experimental boiling- and melting point as descriptors. The calculation is based on the lowest observed melting- and boiling temperature. The determined value 0.00451 Pa at 25 °C refers to the monoester of alcohols, C16 -18, ethoxylated phosphates as worst case result. The vapour pressure for the diester of alcohols, C16 -18, ethoxylated phosphates was calculated to be 0.00843 Pa at 25 °C.
The experimental study (I. Linvingston, 2012) according to EU Method A.4 (static method) was devalidated because of the method is usually not suitabble for multi component systems. Small amounts of volatile subcomponents may increase the vapour pressure by several orders of magnitude.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.
