Additional information
The vapour pressure of Octadecan-1-ol, ethoxylated, < 2.5 EO (CAS 68439 -46 -3) was determined experimentally using boiling point measurements at different pressures and estimated by calculation based on the Grain-Watson Method (according to OECD 104) or the modified Grain method (EPIsuite v4.10).
The experimental value was considered to be not reliable, as it fell outside the recommended range for DSC-based vapour pressure deduction (range: 1-1000 mbar). Alternatively, the Grain-Watson estimation procedure according the OECD Method 104 was applied, which takes into account melting point and boiling point data.
Additionally, the vapour pressures of possible individual constituents of the substance were calculated using EPIsuite v 4.10 (MPBPVP v 1.43). In order to derive a vapour pressure value for the whole substance, weighting based on normalized composition was applied to the individual data.
In view of the low vapour pressure values obtained from the calculations, calculated values from both estimation methods are used to derive the key value for chemical safety assessment purposes
