Hi ......you may try using the dialysis bag. Take your formulation in Dialysis bag and dip it in a medium having surfactants (like SLS, Tween 80). Study the dissolution by analysing the outer medium in different interval of time.
Hi...I think that using dialysis bag is a good idea, but you should use a phosphate buffer pH 7.4 as a medium as it is closer to tissue pH(no surfactant). use temp 37 C and a suitable magnetic stirring.withdraw aliquots from the supernatant and replace the volume to keep sink condition.
