Abstract: | The effect of dimethyl sulfoxide (DMSO) and its nearest homologue diethyl sulfoxide (DESO) as a polar cosolvents on the binding of vitamin E to water + DMSO (DESO) containing reversed micelles of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) has been investigated by a spectrophotometric method. The results suggest that compare with water without organic cosolvent-containing reversed micelles in this case an increase of binding constant of vitamin E in reversed micelles takes place. The results obtained shown that with the addition of DMSO and DESO it will be possible to monitoring a penetration of vitamin E into micellar core. |
