One of the popular formulations is microemulsion in cosmetics. A kind of microemulsions is liquid crystal emulsion. Liquid crystal emulsion is used by wrapping functional ingredients. As the meaning of the name, Liquid crystals (LCs) are a state of matter that has properties between those of a conventional liquid and those of a solid crystal. There are various types of Liquid crystals (LCs) consisting of micelles or two layer structures of surfactants. Recently, microemulsion has been studied to improve its stability in thermodynamics of colloid science field. In this study, we prepared the microemulsion with PEG-8 Capryliccapric Glycerides and Polyglyceryl-3 Diisostearate. We studied the microemulsion with different oil types and different and cosurfactant content ratio. Also, the aim of this study is to develop a facial oil or a cleansing oil containing liquid crystal emulsion with functional ingredients.
