Description of key information
OECD 104 / EU Method A.4_vapour pressure balance_effusion method_vapour pressure: 0.01 Pa at 25 °C; 0.457 Pa at 99 °C for magnesium C20-24 sulfonate and 0.012Pa at 25 °C, 0.039 at 40 °C, and 0.39 Pa at 70 °C for calcium C15-36 sulfonate.
Key value for chemical safety assessment
- Vapour pressure:
- 0.01 Pa
- at the temperature of:
- 25 °C
Additional information
The WOE from the studies by Tremain, 2014 and Tremain, 2012 using the vapour pressure balance (effusion method) in accordance to OECD Guideline 104/EU Method A.4 is that the key vapour pressure value is 0.01 Pa at 25 °C. Vapour pressure values of 0.01 Pa at 25°C and and 0.457 Pa at 99°C were determined for magnesium C20 -24 sulfonate, and vapour pressure values of 0.012 Pa at 25°C, 0.039 Pa at 40°C, and 0.39 Pa at 70°C were obtained for calcium C15 -36 sulfonate. These studies show a clear temperature related response in vapour pressure: 0.01 Pa at 25°C (0.012 Pa at 25°C), 0.039 Pa at 40°C, 0.39 Pa at 70°C, and 0.457 Pa at 99°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.
