“…Results showed that smooth, slippery, and moist sensations on the human skin are induced by a fric-tional phenomenon 10−12) . In the previous study, the friction of foundations and cosmetic dispersions, as applied on artificial skin, was evaluated using a sinusoidal motion friction evaluation system 13,14) . The resultant friction parameters were subjected to principal component analysis (PCA) that provided the principal component (Z) .…”

Frictional properties are one of the most important physical factors in the design of powder cosmetics. In this study, 21 powder cosmetics were applied to artificial skin, and their friction characteristics were evaluated using a sinusoidal motion friction evaluation system. Three friction profiles were observed that depended on the sliding velocity. Principal component analysis showed that the principal component (Z), which characterized the friction dynamics of powder cosmetics, included the static friction coefficient (μ s ), the kinetic friction coefficient (μ k ), the delay time (δ), and the viscosity coefficient (C). Furthermore, a cluster analysis on Z suggested that powder cosmetics can be classified into three groups according to their friction dynamics. These results may be helpful to understand the phenomena that occur during the application of powder cosmetics.

that measures friction under dynamic conditions with constantly-changing velocity has been developed and is attracting attention 9−12) . This system can evaluate frictional phenomena on short timescales at the beginning of motion, velocity dependence of frictional force over a wide range, and hysteresis that reflects dependence on forces previously applied to an object. In addition, we used the system to evaluate the frictional force of foam composed of a surfactant aqueous solution. We observed a hydrodynamic stable pattern in which the friction force increased as a function of the velocity, without any static friction 13) . The foam was lubricious, less dependent on the vertical force, and more durable to mechanical stimuli in the thickeneradded system.In this study, the foams of commercial body cleansers were assessed using a sinusoidal-motion friction evaluation system: the frictional force of the foam between two acrylic plates was measured when the foam was rubbed under sinusoidal motion, and the shape of the foam was observed using a microscope. The viscosity of the cleaning agents and porosity of the foams were evaluated to determine their effect on the frictional force.
