Description of key information
Study scientifically not necessary / other information available - Data waiver in accordance with column 2 of Annex VII, section 7.6: The substance has, based on EPIWIN estimates, an extremely low water solubility below 0.1 mg/L, which is consistent with expectation based upon chemical structure. The substance therefore meets the criteria for data waiving. The hydrophobic nature of the substance and the presence of the mineral oil is, however, likely to lead to micelle formation at the surface of water. It is hypothesised that the ionic sulfonate head will be attracted to water while the hydrophilic tail will tend to the oil, which may have the effect of forming an emulsion which may, in turn, lower the surface tension of the water phase.
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.
