Recognition Mechanism of the "Sara-sara Feel" of Cosmetic Powders.

The Sara-sara feel, which means "a state in which things are not damp or sticky and feel dry," is a preferred tactile sensation when people touch human skin, hair, clothing, and cosmetics. In this study, the Sara-sara feel was evaluated for silicone powder, cellulose powder, hydrophobized sericite powder, and various mixes of these powders. It was found that the highest Sara-sara feel score was achieved by the silicone powder.

Physical origin of a complicated tactile sensation: ' feel'.

feel is defined as a texture that is moderately moisturized; however, many people experience ' feel' when they touch a dry solid material containing little liquid. Here, feel was evaluated for 12 materials. We found that the highest score of feel was achieved by powders.
