The tactile texture of water is not necessarily favourable. When 20 subjects applied 0.1mL of water and five thickener solutions to artificial skin, the favourability score for water was the lowest among the six liquids. This unfavorability is caused by non-smooth and stick-slip feel, which reflect the increase of friction coefficient and their drastic changes on wet skin. The Stribeck plots show that the rupture of a fluid film on human skin can induce the stick-slip feel during application. These findings could potentially be applied for the design of cosmetic products and cleansing products.
