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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 232-414-4 | CAS number: 8016-81-7 The residue from the distillation of tall oil. It contains primarily high-boiling esters of fatty acids and rosin. It may also contain neutral materials, free fatty acids and rosin acids.

Description of key information
Vapour pressure: 0.00159 Pa obtained by prediction
Key value for chemical safety assessment
- Vapour pressure:
- 0.002 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of the whole substance was determined by calculation. The mole fraction of each constituents of TOP was multiplied by its vapour pressure. The result obtained was summed together to obtained the predicted total vapour pressure of the substance. In available supporting study, a vapour pressure of 2 mmHg and 28 mmHg at 230°C and 300°C respectively has been reported for the test
substance.
However, for the purpose of environmental assessment, predicted vapour pressure of individual constituents of the substance is meaningful. Individual samples could have higher vapour pressure if any unexpected impurities are present.
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.
