Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The vapour pressure of Tall oil, reaction products with N-(2-aminoethyl)piperazine, has been determined according to the OECD Guidelines for the Testing of Chemicals, No 104, by the gas saturation method. The vapour pressure was examined at three different temperatures (49°C, 36°C and 23°C).The analyte was liquid at all measured temperatures. The flow rates were varied between 150 and 750 ml/min and the analysed gas volume was typically between 50 -250 l.
Calculated vapour pressures:
At 49°C: 5.10 -7 Pa
At 36°C: <2.10 -7 Pa (detection limit at 173 l analysed gas volume)
At 23°C: <3.10 -7 Pa (detection limit at 249 l analysed gas volume)
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 23 °C
Additional information
The vapour pressure was very low, and it was not possible to calculate an exptrapolated vapour pressure at 20°C and 25°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
