The objective of this study is to quantify the tactile sensation by physical indexes for material design of cosmetics or fabrics. We tried to indicate the sensory scores of tactile sensation as a combination of physical indexes. In order to extract the principal factors of tactile sensation, factor analysis was applied to the sensory evaluation data of skin lotions, whose tactile sensation is designed experimentally. Extracted factors were related to physical indexes by multiple regression analysis, and the sensory score was estimated by using the physical indexes such as viscosity, contact angle, friction coefficient and weight loss by temperature increase.
