Additional information

No study is available for C10 AO however a study is available for another member of the amine oxide category, C12-14 AO. In this study [Lammens M & Rottiers A (2002)] a saturated aqueous solution, based on visual observation, was prepared by mixing 10 g of lyophilised test substance with 15 mL of deionised water. This mixture was stirred for 24 hours at room temperature followed by centrifugation at 2500 rpm to separate undissolved solids from the aqueous phase. The concentration of the substance dissolved in the aqueous phase was analysed using a simplified DBAS method. The water solubility of the substance was 409.5 g/L. No information is given in the report on stability of the lyophilised substance, but the result is in line with actual concentrations of amine oxide achieved during routine manufacturing and is considered to be reliable. This result is read across to C10 AO and is likely to represent a worse case as the shorter chain length is expected to result in an increased water solubility compared to the C12-14 AO.
