摘要

本研究制备了由c12 -20烷基糖苷、c14 -22醇、苯乙烯醇组成的液晶乳剂，并利用各种分析设备进行了结构分析。首先，利用偏光显微镜和冷冻扫描电镜观察了液晶乳剂的重要特征——马尔氏交叉图案和多层结构。DSC证实了液晶相的形成，小角x射线散射(SAXS)证实了层间间距约为305 Å的多层片层结构。用广角x射线散射(WAXS)证实了烷基链的排列形成了层状液晶乳液的正交结构。这些结果表明，通过对液晶乳液结构的研究获得的各种物理性质的信息有望在未来的化妆品开发中得到广泛的应用。

Structure Analysis of Liquid Crystal Emulsions Using X-ray Scattering Analysis

: In this study, we prepared liquid crystal emulsions composed of C 12-20 alkyl glucoside, C 14-22 alcohol, and behenyl alcohol and performed structure analysis using various analytical equipment. First, as an important characteristic of liquid crystal emulsions, maltese cross patterns and multi-layer structure were observed by a polarized microscope and cryo-SEM. Also, formation of liquid crystal phase was confirmed by DSC and multi-layer lamellar structure having an interlayer spacing approximately 305 Å was confirmed by small angle x-ray scattering (SAXS). The alkyl chain arrange-ment formed orthorhombic structure of a lamellar structure of the liquid crystal emulsion was confirmed by wide angle x-ray scattering (WAXS). These results suggest that information on the various physical properties obtained through the research of liquid crystal emulsion structure is expected to be widely used in cosmetics development in the future.
