Description of key information
Testing has not been performed for surface tension since Dimethyl octadecylphosphonate (DMOP) is not expected to have surface activity.
DMOP is highly insoluble in water (the water solubility was visually assessed to be <1.07E-03 g/l at 20.0 ± 5°C (Fox, 2013) which is supported by the (Q)SAR prediction of 7.656E-07 g/l 25°C derived using WSKOW v1.42 . According to OECD Guideline 115 (Surface Tension of Aqueous Solutions), testing need not be performed when the water solubility of a substance is < 1mg/l.
Key value for chemical safety assessment
Additional information
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.
