Shittori
feel is defined as a texture that is moderately moisturized; however, many people experience ‘
shittori
feel’ when they touch a dry solid material containing little liquid. Here,
shittori
feel was evaluated for 12 materials. We found that the highest score of
shittori
feel was achieved by powders. Multiple regression analysis showed that
shittori
feel is a complex sense of moist and smooth feels. We analysed the relationship between the physical properties and the moist/smooth feels to show how subjects felt certain feels simultaneously. The moist and smooth feels are related to the surface roughness and friction characteristics of the materials. The moist and smooth feels can be perceived when the finger starts to move on the material surface and when the finger moves and rubs the material surface, respectively.
Shittori feel is defined as a texture that is moderately moisturized and is one of the most favorable textures for many Japanese. In this research, we studied the relationship between the tactile and physical properties of cosmetic powders to determine the specific factors that make up shittori feel. We selected nine cosmetic powders with different sizes, shapes, and touch to conduct physical and tactile evaluations. These evaluations suggested that shittori feel is a complex combination of moist and smooth feels induced by a frictional phenomenon on skin. The moist and smooth feels are perceived when the finger starts to move and when the finger rubs the powders, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
