“…Usually, TiO 2 and ZnO are used in sunscreens for the sensitive skin and for the sunscreens with high sun protection factor , but they can also play the role of both, emulsion stabiliser and photograph protector, by using an important quantity of physical filters (35%) of titanium dioxide and/or zinc oxide type combined with melatonin or green coffee oil . In our recent study, we described the microscopic, macroscopic and applicative proprieties of the TiO 2 stabilized system from an instrumental point of view .…”

Objective The increasing interest for the Pickering emulsions is based on the possibility to replace classical emulsifiers by the solid particles. This approach is extremely attractive for the cosmetic field. But, the main difficulty is to obtain stable emulsions with appreciable skin feel. However, there is no information about the texture of such systems. The aim of this study is to formulate and describe the textural properties of cosmetic Pickering emulsions compared with conventional systems. Methods Three metal oxides were selected: titanium dioxide, zinc oxide and silicon dioxide, able to form stable and totally emulsified systems. A conventional emulsifier was used to formulate the emulsion of reference. Finally, the mixture of two emulsifying systems, combining both, surfactant and particles, was also studied. Then, a sensory panel was asked to quantify the intensities of the perception of the seven discriminating attributes. Results Each particle brought its properties to the textural perception of the emulsion. TiO2 particles ensured the whitening effect of the emulsions, SiO2 provided the screech residue, whereas ZnO gave intermediate results. The conventional surfactant was perceived as glossy, greasy and more difficult to spread. The particle/surfactant mixtures gave mostly in‐between results. Conclusions The study shows that the sensory profile of Pickering emulsions is indirectly and directly governed by the particle properties used for the emulsion stabilization: indirectly, through affecting the emulsion orientation (oil in water or water in oil), the droplet organization and viscosity, and directly, through the particle perception on the skin surface.

“…Unlike microemulsions, nano-emulsions exhibit metastable behavior, wherein their structural configuration is contingent upon the specific preparation methodology employed [8]. Presently, the generally accepted range for defining nano-emulsion systems predominantly spans droplet sizes of 20-200 nm [9]. In recent years, research emphasis has centered on formulating nano-emulsions through distinct methodologies, broadly categorized as high-energy and low-energy methods [10].…”

Advancement in nanotechnology brings a revolutionary change in the field of textile finishing. Textile finishing is a chemical or a mechanical process to impart functional properties to the textile to provide comfort for wearer. Today’s textile manufacturers focus on the manufacture of smart and functional textiles that are equipped with antifouling, anti-wrinkle, crease-resistant, water-repellent, flame-retardant, and soil-repellent properties for consumers’ safety and well-being. A wide variety of functional chemical finishes are available in the market to meet the ongoing challenges in the textile sector. Nano-emulsions significantly contribute to a wide variety of functional finishes to provide advanced hi-tech applications for present and future textile consumers. Both natural and synthetic polymers have been utilized for the synthesis of functional finishes by employing polymeric nano-emulsions on cotton, wool polyester fiber as well as textile. Thus, nano-emulsions provide an inherent property to textile and stimulate the economic growth of functional textile market.
