Formatted abstract
Emulsions are a class of formulations used from paints to drug delivery in dilute to concentrated form, made by mixing two immiscible phases with an emulsifier. This presentation is divided into two parts. The first part is a review of methods adopted to evaluate surfactants/emulsifiers and the inadequacies existing to explain the role of impurities in flocculation, coalescence, and Ostwald ripening, leading to emulsion instability. In the second part, emulsion instability is predicted in a novel approach, wherein the purity of the components in oil and water phases, presented in two individual matrices, is perturbed. The addition of the perturbed matrices and the solution of its determinant is construed as the onset of emulsion instability.
