Special Issue Information

Dear Colleagues,

Emulsions, whether as products or involved in processes, are all around us in the modern world. The scope of emulsions applications is a result of the skill and imagination of researchers in this field over many years. For decades, the adage that “oil and water do not mix” has been challenged, and with the ready availability of numerous natural and synthetic emulsifiers with molecular characteristics differing in oil/water compatibility, these unlikely bed-fellows are now able to work together in ways that the individual liquids cannot.

This Special Issue is therefore a celebration of emulsion research, embracing both fundamental and applied aspects, which enables the contemporary diversity of emulsions in science and technology to be highlighted.

Of particular interest are contributions in the following categories, relevant to emulsion formulation, characterization, and applications, namely:

  • Developments in complex emulsions (e.g., phase-change, and multiple and Janus emulsions)
  • Oil/water separation—demulsification by physical and chemical means
  • Pickering–Ramsden emulsions
  • Emulsion rheology
  • Emulsion-derived materials and morphology control
  • Highly concentrated emulsions—formulation, properties, and applications
  • Oil-in-oil and water-in-water emulsions
  • Influence of interfacial properties on emulsion characteristics
  • In-situ measurements of emulsion interfacial properties

Contributions are also welcome from the many industries that manufacture or handle emulsions and emulsion products as part of their day-to-day businesses, including food, paint and ink, agrochemical, pharmaceutical, petroleum, and cosmetic industries, to name but a few.

Oil-In-Water Microemulsions for Thymol Solubilization
Colloids Interfaces 2019, 3(4), 64; https://doi.org/10.3390/colloids3040064 - 02 Dec 2019

Essential oil compounds (EOCs) are molecules with well-known antimicrobial and antipest activity. However, such molecules possess limited solubility in water, making their handling difficult. This work aimed to enhance the distribution of a solid essential oil compound, thymol, using oil-in-water (o/w) microemulsions for its solubilization. The use of mixtures formed by an alkyl polyglucoside (APG) and soybean lecithin (SL) allowed for stabilization of the o/w microemulsions in a broad range of compositions, with the total concentration of the mixture of the two surfactants (APG+SL) and the APG:SL ratio both being essential for controlling the nature of the obtained dispersions. The microemulsions obtained using oleic acid as the oil phase and with compositions far from those corresponding to the onset of the emulsion region showed a good efficiency for thymol solubilization. This is an advantage from a stability point of view, as well as for ease of thymol preparation. The present work opens new alternatives for designing eco-sustainable formulations for EOC solubilization, with the possibility of preparing the formulations at the place of use, thereby saving transport costs and reducing the emission of pollutants.
