Description of key information
The test substance,molybdenum trioxide, reaction products with bis[O,O-bis(2-ethylhexyl)] hydrogen dithiophosphate (Oil Free),is essentially insoluble in water. QSAR calculations estimate that water solubility is below 10-6mg/L; the U.S. EPA EPISuite models WSKOW and WATERNT predict water solubility values of 2.381 × 10-17mg/L and 9.9508 × 10-7mg/L, respectively. The UVCB substance includes a fraction that does not contain molybdenum that has a measured solubility of 0.05 μg/mL at 20 °C.
Additional testing is waived based on the low solubility predicted by the QSAR models, the low solubility observed for the fraction not containing molybdenum, and the inherent difficulty in testing poorly soluble inorganic complexes.

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.
