![]() ![]() Many specialty chemicals suppliers have produced emulsifiers, e.g. The unique properties and the applications of liquid crystal emulsion have attracted many researchers in pharmaceutical and cosmetic product to do extensive studies on the special structure emulsion, including preparation and properties. The formation of liquid crystal structure in emulsion depends not only on the composition of the emulsion formulations, but also the preparation processes. It is the ordered arrangement of surfactant and oil molecules formed at the oil-water interface, and this ordered arrangement makes the emulsion of liquid crystal structure showing better application performances than conventional emulsion systems in terms of stability, controlled release and moisturizing. The liquid crystal emulsion is a new type of emulsion which is different from the traditional emulsion system. And the improved moisturizing properties of such emulsion may be attributed to the liquid crystal structure. ![]() On the other hand, liquid crystal emulsion shows typical shear-thinning property upon usage, which leads to an excellent skin sensory feeling. The rheological data shows that liquid crystal emulsion exhibits solid-like (elastic) property during storage, which is favorable for good stability. Upon application on the skin, the liquid crystal structure of emulsion was found to transform into other form with rubbing, although the liquid crystal structure still remains. And after emulsion being stored for 18 months, the crystal structure starts to decompose. The liquid crystal structure doesn’t change significantly during the storage within 12 months. The results show that the liquid crystal structure at oil-water interface in the emulsion forms gradually with cooling process after homogenization. Besides, the rheological and moisturizing property of the liquid crystal structure emulsion was investigated as well. In this paper, the formation of liquid crystal structure in preparation of emulsion and the change of those liquid crystal structures during storage and usage were studied. ![]() Keywords: liquid crystal emulsion rheology stability moisture ![]() Received January 29 th, 2013 revised March 2 nd, 2013 accepted March 9 th, 2013 This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
