A study of surfactant effects on the physical chemistry of vegetable and mineral oils

Abstract

The behaviour and operation of a stable dispersion within the pharmaceutical industry is indispensible, especially in methods involving particle size analysis. The performance of a stable dispersion ultimately depends on the properties of the individual constituent particles, which are often neglected. The objective of the study was to highlight the possible relationship between the physicochemical properties of the constituents, namely the density, surface tension and kinematic viscosity of six different types of oils from both vegetable and mineral sources, in conjunction to four different types of surfactants at different concentrations. The study also entailed comparing the results obtained to the ones conducted by Ellul (2012) to determine the influence of a change in oil brand.
