Special Issue Information

Dear Colleagues,

Emulsion science and technology have been used for a long time to create a wide variety of commercial emulsified products, including food, pharmaceutical, and cosmetic products. Moreover, this type of colloidal system has been used as a vehicle for the encapsulation and delivery of different bioactive compounds, such as antioxidants, vitamins, and fragrances. In the last several years, there have been advances in emulsion science to improve the quality and performance of different emulsion-based products using new techniques and structural designs. This new generation of advanced emulsions may lead to products with improved quality and functionality. Therefore, we invite all researchers in the area to contribute to this Special Issue by submitting reviews or original articles. Manuscripts addressing recent advances in the creation of novel emulsion systems are welcome. The development and application of advanced emulsion technologies are considered for this Special Issue. In this context, contributions focused on emulsions stabilized by particle-based emulsifiers (Pickering emulsions), high-internal-phase emulsions, multilayer emulsions, nanoemulsions, multiple emulsions, emulgels, oleogel-based emulsions, bigels, water-in-water emulsions, and novel emulsifiers will be considered. Manuscripts on recent advances in emulsion-based delivery and encapsulation approaches are also welcome.

The design of emulsions at the nanoscale is a significant application of nanotechnology. For spherical droplets and a given volume of dispersed phase, the nanometre size of droplets inversely increases the total area, A=3Vr, allowing greater contact with organic and inorganic materials during application. In topical applications, not only is cell contact increased, but also permeability in the cell membrane. Nanoemulsions typically achieve kinetic stability rather than thermodynamic stability, so their commercial application requires reasonable resistance to flocculation and coalescence, which can be affected by temperature changes. Therefore, their thermoresponsive characterisation becomes relevant. In this work, we analyse this response in an O/W nanoemulsion of Palmarosa for antibacterial purposes that has already shown stability for one year at controlled room temperature. We now study hysteresis processes and the behaviour of the statistical distribution in droplet size by Dynamic Light Scattering, obtaining remarkable stability under temperature changes up to 50 °C. This includes a maintained chemical composition observed using Fourier Transform Infrared Spectroscopy and the preservation of antibacterial properties analysed through optical density tests on cultures and the Spread-Plate technique for bacteria colony counting. We obtain practically closed hysteresis curves for some tracers of droplet size distributions through controlled thermal cycles between 10 °C and 50 °C, exhibiting a non-linear behaviour in their distribution. In general, the results show notable physical, chemical, and antibacterial stability, suitable for commercial applications. Full article
