新型乳化体系及其在化妆品中的应用（Ⅲ）——Pickering乳液

doi:10.3969/j.issn.2097-2806.2023.11.003

摘要/Abstract

摘要：

Pickering乳液是最近二十年发展起来的一种新型的乳化体系。体系中油、水界面通常为微米级或纳米级固体颗粒形成的稳固的颗粒膜，这些固体颗粒依靠自身的表面润湿性，近乎不可逆的吸附于油、水界面，进而稳定乳滴。与传统乳化剂相比，固体颗粒廉价易得、对环境绿色友好、易于修饰且赋予乳液更高稳定性等，使得Pickering乳液在石油开采、新材料合成，特别是食品、医药以及化妆品领域的应用中表现出诸多的优势。本文首先介绍了Pickering乳液及常用于稳定Pickering乳液的固体颗粒，并阐述乳液稳定机理，总结影响体系稳定性的因素，详述Pickering乳液在化妆品领域的应用及其应用优势。在此基础上，对特殊Pickering乳液，包括多重Pickering乳液、Pickering-Janus乳液进行了简单介绍。最后针对Pickering乳液未来发展方向，包括Pickering乳化剂、Pickering乳液制备以及Pickering乳液应用等方面需开展的工作提出了个人看法，希望为Pickering乳液的有效开发及合理应用提供参考。

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.
