Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The vapor pressure of reaction product of oleyl alcohol with polyphosphoric acid was estimated by using by means of the program MPBPWIN
(EPIsuite). The vapour pressure of the main component oleyl phosphate was estimated to be 8.07 x 10-9 Pa at 25 °C using the Modified Grain
method. The components of the UVCB substance, which contain phosphate groups had estimated vapour pressures ranging from approximately
8 x 10-9 to 2 x 10-6 Pa at 25 °C . The components of the UVCB substance, which contain alcohol groups had estimated vapour pressures about 0 Pa at 25 °C . In conclusion it can be said, that the volatility of the UVCB test substance “Reaction product of oleyl alcohol with polyphosphoric acid” is
extremely low or negligible.
Key value for chemical safety assessment
Additional information
The test method for the determination of the vapour pressure of a substance as described for liquids in test guideline A.4 of Council Regulation (EC) No 440/2008 was replaced by a theoretical based evaluation, because most experimental methods are only recommended to be used for the measurement of vapourpressure from < 10-4to 105 Pa.

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).
