This study reveals the close relation between sensory evaluation and rheological measurement about smoothness of creams. A rheological measurement has advantage over sensory evaluation because it gives robust and unchanging results while sensory evaluations cannot. Cosmetics gives satisfaction to users after it has been used. But during the usage of cosmetics, customers can be satisfactory if the smoothness of cosmetics catches the users mind. To test the smoothness of cosmetics large makers pay much to establish and maintain trained panels. But for a small and medium companies the expenditure for the panels are so large and unbearable. If we find a mechanical and unchanging method, it can be helpful to many small cosmetics companies. In this study we conducted sensory evaluation with university students and rheological measurement with rheometer. And we did regression analysis to connect the results of sensory evaluation and rheological measurements. It is concluded that rheological measurements can replace sensory evaluation of smoothness of creams.
