Effects of dissolved gases in surfactant dissolution media

Abstract

The effects of dissolved gases on the performance of aqueous dissolution media have been studied extensively, but little has been published regarding the effect of dissolved gases on surfactant containing dissolution media. There are various methods available to control the level of dissolved gases in surfactant media, but regardless of the method used or level of dissolved gases achieved,the media will equilibrate to atmospheric conditions within approximately one hour. Therefore,elaborate techniques to control the level of dissolved gases are unnecessary,and the variability associated with dissolved gases can be minimized by performing the dissolution experiment at equilibrium.
