Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There is no experimental data available of vapour pressure for the substance: Reaction products of lauric acid and oxybis(propanediol). As the substance is a UVCB substance, the measurement of vapour pressure is scientifically not necessary, the prediction methods may be used to generate vapour pressure data on the individual components.

 

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.

 

Therefore the vapour pressure of Reaction products of lauric acid and oxybis(propanediol) should be lower than the vapour pressure of Dodecanoic acid 3-(2,3-dihydroxy-propoxy)-2-hydroxy-propyl ester (0.01 Pa).
