Additional information
The vapour pressure of alcohols, C12 -15, ethoxylated, 1 -2.5 EO was deduced from the studies on structurally similar substances.
Literature values for dodecan-1 -ol, tridecan-1 -ol, tetradecanol and pentadecan-1 -ol (ethoxylation degree 0) show a vapour pressure of 0.113 Pa, 0.0581 Pa, 0.0147 Pa, and 0.00513 Pa at 25 °C respectively.
Vapour pressure is a property which shows a negative correlation with the number of CH2 groups. The higher the number of CH2 groups, the lower the vapour pressure. There is also a correlation between vapour pressure and the degree of ethoxylation. Calculations show the higher the degree of ethoxylation, the lower the vapour pressure.
Therefore the vapour pressure of alcohols, C12 -15, ethoxylated, 1 -2.5 EO is deduced to be < 1 Pa at 25 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
