Facial cleansers are expected to have psychological benefits such as a refreshing effect in addition to the functional aspect of keeping the skin clean. Facial cleansers are required to have functionality, safety, and a comfortable feeling when used. In particular, the “sappari” feeling, which means a sense of cleanliness and comfort, is an important factor in the refreshing effect of face washing. In this study, we used the evaluation grid method to extract a qualitative evaluation structure regarding the feeling of using a facial cleanser and clarified the factors that determine the “sappari” feeling when using a facial cleanser. Furthermore, to clarify the causal relationship between the factors extracted by the evaluation grid method and the “sappari” feeling, we performed an analysis using structural equation modeling. As a result, it was revealed that the “sappari” feeling is mainly formed by the “dirt removal feeling” and the “cool feeling”. In addition, it was shown that although the “foam quality” does not directly affect the “sappari” feeling, it indirectly contributes to it through the “dirt removal feeling”. The results of this study will contribute to the design of a facial cleanser with a comfortable feeling that is excellent in the “sappari” feeling, and will lead to the development of a facial cleanser that contributes to improving the quality of life, such as mental stability and stress reduction through the refreshing effect.
