Description of key information
The octanol-water partition coefficients (Pow) for components of DOWFAX™ 8390 solution surfactant were estimated according to OECD Guideline 117: HPLC Method. The estimated log Pow values range from less than 1.00 to 1.82.
Key value for chemical safety assessment
Additional information
The octanol-water partition coefficients (Pow) for components of DOWFAX™ 8390 solution surfactant were estimated according to OECD Guideline 117: HPLC Method. The estimated log Pow values range from less than 1.00 to 1.82. In the defined HPLC assay, three chromatographic peaks were observed which accounted for approximately 100 % of the test material composition. The HPLC retention times for these components correlated to estimated log Pow values ranging from less than 1.00 to 1.82. It should be noted that the components of this substances possess ionizable functional groups (i.e., aromatic sulfonates) which cannot occur in a fully non-ionized (protonated) state within the pH range of 0 – 14. By definition, the octanol/water partition coefficient (log Pow) describes partitioning of non-ionized species between mutually-saturated water and octanol solvent phases. By this definition, log Pow values cannot be determined experimentally for components of the DOWFAX 8390 solution surfactant. However, the estimated log Pow values reported here may provide a reasonable representation of expected partitioning behavior among aqueous and hydrophobic (organic matter) phases in the environment. The components of DOWFAX 8390 solution surfactant are, therefore, expected to have low potential for bioaccumulation in the aquatic environment.
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.
