S0501-2-6 Sensory study on the application of cosmetic base oil and its verification by virtual reality

Abstract

When some cosmetic base oil was applied, the oscillatory friction of 50 Hz was observed. It was revealed that this oscillation was caused by the vibration of the moving plunger. It depended on the surface characteristics and the oil viscosity if this vibration appeared or not. Preferable feeling was produced by the vibration. A piezo vibrator was appended to the virtual application device, with which the sensory test was conducted. This virtual application with the vibration also produced preferable feeling.
