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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The vapour pressure is < 2.13E-3 Pa at 25 °C.
Key value for chemical safety assessment
Additional information
There is no experimental data for vapour pressure available.
The key value of vapour pressure is estimated by using category approach based on the available data for the main constituents of the substance, C12 Lauric acid (CAS 143-07-7) and C14 Myristic acid (CAS 544-63-8). C12 Lauric acid (CAS 143-07-7) had the higher vapour pressure of these two consitutents (see explanation below).
According to the theoretical principle of Raoult’s law, the vapour pressure of mixture is equal to the mole-fraction-weighted sum of the components' vapour pressures:
ptot= ∑ pixi
The vapour pressure of mixture should be lower than the vapour pressure of the component which has the highest vapour pressure in its pure form (C12).
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.
