新型乳化体系及其在化妆品中的应用(V)OACSTPCD

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.
