This study is about the development of cholesteric liquid crystals (CLCs), which are highly applicable to cosmeticsformulation. The CLCs made from non-animal origin were chosen not only because they are free of animal virusesbut also because they give a sense of security to the cosmetic consumers. Three kinds of new cholesteric derivatives(CI, CC, CN) were synthesized using non-animal cholesterol [NAB cholesterol (ARCH LONZA)], which wasoriginally made by fermentation process. To develop high applicability to cosmetics formulation, we attempted to findout the optimum compositions in which CLCs can maintain their color over a wide range of temperature. The CLCsin 41 different compositions were prepared by the combinations of three cholesteric derivatives and a visual evaluationmethod was employed to determine the range of temperature at which the CLCs display their color. The 205 UV-VISspectral data obtained from 41 CLCs at various temperatures were simultaneously analyzed to investigate the criticalfactors affecting the characteristics of the CLCs. Results showed that A4, A5, A6 and A7 were the best compositionsto cosmetics formulation. A6 composition had a great moisturizing effect by the artificial skin test (AmoReSkinTM).
