摘要/Abstract

摘要：

Janus乳液是内相由两种互不相溶、彼此独立、界面分明的液相组成的单液滴形式的多分散体系，其内相两腔室的物质组成不同，两腔室的性质和形状具有不对称性，是一类特殊类型的各向异性乳液。Janus乳液不但保持了传统乳液的基本性质，其两腔室、多样的界面和灵活的结构、较大的界面面积和独立的空间等独特的结构优势使其对诸多功能性物质的选择性增溶、隔离、保护以及缓释等作用优于传统乳液。Janus乳液具有结构多样、定量可调的特点，可通过改变乳化剂种类、含量及各相的比例等实现对体系内界面的种类、数量和相对面积的调整，进而调控体系性质，以满足不同的使用需求。Janus乳液在化妆品、食品、生物医药以及微反应器等领域具有潜在的应用前景。本文介绍了Janus乳液及其制备方法，总结了影响Janus乳液性质的关键因素，概况了Janus乳液的性能优势。并基于目前对Janus乳液的研究及应用现状，展望了Janus乳液在化妆品领域的应用前景，并简单介绍了另外一种新型各向异性乳液——Cerberus乳液。同时，指出了Janus乳液在化妆品中应用面临的问题，并对有必要开展的研究工作提出了个人观点，旨在为性能优异的Janus乳液的开发及其在化妆品领域的实际应用提供参考信息。

Abstract:

Janus emulsion is a polydisperse system composed of two immiscible liquid phases in the internal phase. The composition, physicochemical properties as well as the shapes of the compartments in the internal phase of Janus emulsion are asymmetry, which endow the emulsion anisotropy. Janus emulsion not only maintains the fundamental properties of the traditional emulsion, the selective solubilization, isolation, protection and sustained-release property to the functional materials are better than that of the traditional emulsion due to its unique structural advantages including two isolated compartments, various interfaces and flexible structure, larger interface area etc. The topologies of Janus emulsion are diverse and the properties of Janus emulsion are quantitatively tunable. The type, quantity and relative area of the interface within the system can be adjusted by tailoring the type, content of emulsifier and the proportion of each phase, so as to regulate the properties of the system to meet different requirements of application. The Janus emulsion has potential applications in the fields of cosmetics, food, biomedicine and microreactor. In this paper, the Janus emulsion and its preparation method are introduced firstly and then the factors of affecting the properties of Janus emulsion are summarized. The performance advantages of the Janus emulsion are elaborated too. Based on the current research and application status of Janus emulsion, the application prospect of Janus emulsion in cosmetics is discussed. At the same time, another new type of anisotropic emulsion, Cerberus emulsion is also briefly introduced. Finally, the limitations of the application of Janus emulsion in the field of cosmetics are put forward and personal views on the problems to be solved are proposed, which may provide necessary reference information for the development of Janus emulsion with excellent performance and its practical application in the field of cosmetics.
