Substance with a higher vapour pressure need to be assessed more critically, e.g. concerning the release of toxic substances, than those with a lower vapour pressure. For this reason, the calculation was based on the theoretically instead of the experimentally determined vapour pressure.

Description of key information
The vapour pressure is < 0.18 Pa at 20 °C (estimation).
Key value for chemical safety assessment
Additional information
The value of vapour pressure is estimated based on the study reports of the substances ''Sulfuric acid, mono-C12 -14-alkyl (even numbered) esters, ammonium salts'' and ''sodium dodecyl sulphate C12''.
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 ''Sulfuric acid, mono C12 -14-alkyl (even numbered) esters, ammonium salts'' should be lower than the vapour pressure of ''ammonium dodecyl sulphate C12''. Due to the similar chemical structure of ammonium salts and sodium salt, the vapour pressure of ammnoium salts should have the similar trend or be in the similar range like sodium salts. Therefore the vapour pressure of mixture ''Sulfuric acid, mono C12 -14-alkyl (even numbered) esters, ammonium salts'' is estimated to be lower than 0.18 Pa, the value is based on the experiment result for ''sodium dodecylsulphate''. This estimation is more reliable than the Grain-Watson calculation with the substance C12 -14 ammonium salts itself (result: < 9.9 Pa), which also is taken into account in the weight of evidence approach.
