Description of key information
The vapour pressure of teflubenzuron at 20°C was calculated to be 9.16 x 10-7 Pa.
The Henry's law constant of teflubenzuron was calculated to be 6.98 x 10-3 Pa m3/mol at 20°C.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.007
- at the temperature of:
- 20 °C
Additional information
One study on the determination on vapour pressure and Henry's law constant is availble.
Batelle (2005): Determination of vapour pressure and Henry’s law constant of Teflubenzuron (BAS 309 I). DocID according to Draft Assessment Report prepared in compliance with Regulation (EC) No 1107/2009: 2005/1007421; crossreference to Draft Assessment Report according to Regulation (EC) No 1107/2009: B.2.1.5.
This guideline compliant final report accounts the results of vapour pressure and Henry's law constant of teflubenzuron. The vapour pressure of teflubenzuron was determined according to EEC A4. Vapour pressure of teflubenzuron was determined experimentally at 30, 40 and 50°C and the value at 20°C was extrapolated. The vapour pressure of teflubenzuron at 20°C was calculated to be 9.16 x 10-7 Pa.
The Henry's law constant of teflubenzuron was calculated to be 6.98 x 10-3 Pa m3/mol at 20°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.
