Study on the effect of emulsifier on thermal behaviour of concentrated O/W emulsions

Abstract

Some investigations on the capability of differential scanning calorimetry (DSC) for the characterization of concentrated mineral oil in water emulsions indicated certain differences in their thermal behaviour depending upon various factors including particularly the emulsifier. In this paper DSC examinations were undertaken in order to assess the influence of the emulsifier solubility properties, i.e. hydrophile-lypophile balance (HLB values), emulsifier concentration and its distribution between the interface, continuous and disperse phase on the thermal behaviour of O/W emulsions and some of their thermal characteristics. © 1988.
