1 - 2.5 moles ethoxylated
=< 7.7 Pa at 20 °C
The vapour pressure of the substance was determined with
the use of Grain-Watson estimation as outlined in the OECD Guideline
104. The experimental result of the vapour pressure measurement using
the DSC method was not in the appropriate validity range with respect to
this method and it was discarded.
The Grain-Watson calculation is based on the lowest
possible boiling temperature, which in fact is probably a decomposition
temperature. In a peer reviewed SIDS Initial Assessment Profile for
alkyl sulphates (structurally related to alcohols ethoxylated,
sulphated; SIAM 25, 17 -18 October, 2007) it is stated that: "As ionic
substances, all members of this category have extremely low vapour
pressures. Calculated values are in the ranges 1E-11 hPa to 1E-15 hPa
(C8 -18 alkyl sulphates) (...) Therefore, they decompose before reaching
their theoretical boiling points". Thus, the obtained value should be
considered an upper limit of the vapour pressure and accepted for the
risk assessment calculations in the sense of a "worst-case scenario".
