Executive summary:

The vapour pressure of the substance Hydrocarbons, C16 -C20 (even numbered), n-alkanes, isoalkanes, <2% aromatics, calculated according to the ASTM D 2879 method, is < 5 Pa at 20°C.

Description of key information

There is no data available for Hydrocarbons, C14-C20 (even numbered), n-alkanes, isoalkanes, <2% aromatics.However, data is available for structural analogue, Hydrocarbons, C16-C20 (even numbered), n-alkanes, isoalkanes, <2% aromatics. This data is read across to based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.

The vapour pressure of the substance Hydrocarbons, C16-C20 (even numbered), n-alkanes, isoalkanes, <2% aromatics, calculated according to the ASTM D 2879 procedure is < 5 Pa at 20°C.

Key value for chemical safety assessment

Vapour pressure:
5 Pa
at the temperature of:
20 °C
