Evaluation of Tactile Sensation of Cosmetics by Tactile Movement —Application Movement of Skin Care Products—

Abstract

The correlation between tactile sensation and tactile movement during application of cosmetics is important because tactile sensation is induced only by active handling. The aim of this study is to evaluate application feeling of skin care products objectively using motion analysis of human fingers during application. The effect of the application velocity on the sensory evaluation score was investigated. It was shown that the participants tend to apply the skin care products at the velocity which they feel the most comfortable. Based on this result, change in the application velocity by changing rheological property of the skin care product was studied. From these results, it was shown that motion analysis of application is useful to evaluate tactile feelings of skin care products.
