Abstract:

Pickering emulsion is a new type of emulsion system developed in the past twenty years. The oil and water interface in the system is generally a solid particle film formed by micron-scale or nanoscale solid particles. These solid particles nearly irreversible adsorption to the oil and water interface rely on their own surface wettability and thus stabilize the droplets in the system. The solid particles have much advantages compared with the traditional emulsifiers, including cheaper and easier to obtain, higher emulsifying capacity, green and friendly to the environment, easier to modify as well as the higher stability of the prepared emulsions, which make Pickering emulsion show many advantages in the fields of oil extraction, new material synthesis, food, medicine as well as cosmetics. In this paper, the Pickering emulsion, the stability mechanism of the Pickering emulsion and the factors of affecting the stability of the system are introduced firstly. Then, the solid particles can be used to stabilize Pickering emulsion in cosmetics are listed, and the necessary conditions that the solid particles should have are clarified. On this basis, the application of Pickering emulsion in the field of cosmetics is stated in details, and the corresponding advantages of Pickering emulsion in the application of cosmetics are summarized. Furthermore, the unique Pickering emulsions developed recently, including multiple Pickering emulsion and the Pickering-Janus emulsion are introduced. Finally, the personal views on the future development in the direction of Pickering emulsifier, preparation and the application of Pickering emulsion are put forward, which may provide some useful reference for the effective development and reasonable application of Pickering emulsion.
