| Summary: | 碩士 === 萬能科技大學 === 化妝品應用與管理研究所 === 104 === In this study, Sea Buckthorn Oil ∕Rice Bran Oil fragrance emulsion were prepared , using Sea Buckthorn Oil /Rice Bran Oil as oil phase materials, Rose Hydrosol, water ,Glycerin and Xanthan Gum as water phase material. Span80 Tween80 surfactant as emulsifier. The effect of different concentrations Xanthan Gum ,emulsifiers and essential oils on the properties and stability of the Sea Buckthom Oil∕Rice Bran Oil fragrance emulsions were investigated. The experimental results that Sea Buckthorn Oil / Brown Rice Oil fragrance emulsions with 0.6wt% XanthanGum, 1wt% emulsifiers and different concentrations (0,0.3,0.6 wt%) essential oils, the emulsions are weakly acidic. All Sea Buckthorn Oil / Rice Bran Oil fragrance emulsions were shear thinning fluids type. Centrifugal stability test results that fragrance emulsions with good stability by centrifugal speed 3000rpm,30nim condition. Antibacterial test result that antibacterial activity of Escherichia coli from six kinds of essential oils were measured to be , in order: frankincense> Sweet Citrus> Rose wood. Th eantibacterial activity of Propionibacterium acnes from six kinds of essential oils were measured to be , in order: lavender> Rosewood> sweet citrus. The mix essential oils formulations for E.coli antibacterial activity worse than the control group and control group, show that antibacterial activity of essential oils has obvious antagonism. The two batches of mix essential oils formulations (lavender, rosewood, frankincense and lavender, sweet orange, frankincense, geranium, rosewood, orange blossom) have significant antibacterial effect for P. acnes. Also, the effect of sedative and soothing of the autonomic nervous system were inevestigated by the fragrance emulsion with the Lavender、Sweet Orange、Frankincense、Geraium、Rosewood and Neroli essential Oils applied to human skin.The DIACOM–NLS nonlinear analysis of the relieve of autonomic nervous system of human trials, Sea Buckthorn Oil /Brown Rice Oil emulsions fragrance emulsion added 0.3wt% concentration of essential oil can promotion cellular energy in the body and relieveo of sympathetic nervous is more significantly better than the 0.6wt% concentration.The results of this study can be used an important reference for the practical application of aromatic therap.
