A theoretical model is presented to describe the adsorption of surfactant molecules at the water/oil interface for the case when transport across the interface must be considered due to the solubility of the surfactant in both liquid phases (aqueous solution drop in an oil phase). The theory is base

โฆ Synopsis
to be controlled by the distribution coefficient of the surfac-A pendant drop technique has been used to study the adsorption tant between the two adjacent phases as well as by the diffuof a nonionic surfactant, an alkyldimethylphosphine oxide sion coefficients in the two liquids and their volume ratio.
