Executive summary:

Hydrocarbons, C14-C17, n-alkanes, <2% aromatics is measured according to NFT 20 -048. The Vapour pressure is determined to be < 5 Pa at 20 °C and 9 Pa at 50 °C.

Description of key information

There is no data available for Hydrocarbons, C15-C16, n-alkanes, <2% aromatics. However, data is available for a structural analogue, Hydrocarbons, C14 -C17, n-alkanes, <2% aromatics and presented in the dossier. This data is read across to Hydrocarbons, C15-C16, n-alkanes, <2% aromatics 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 substance Hydrocarbons, C14-C17, n-alkanes, <2% aromatics shows a Vapour Pressure < 5 Pa at 20°C.

Key value for chemical safety assessment

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