진동화장품 기기의 사용 효과에 대한 정량적 평가

Abstract

There are now many consumers using vibrating cosmetic devices which have been pioneering a newcategory in the market of cosmetics, but there was no way to evaluate the effectiveness of vibratingcosmetic devices quantitatively. Thus, we devised a method to measure and quantify objectively theeffectiveness of the vibrating cosmetic devices in this study. We fabricated a simple apparatus for adhesiontest, which was conducted upon artificial leather using liquid foundation and face powder. It was shownthat the adhesion ratio in liquid foundation was 4 to 5 times greater when vibration was operated on thevibrating foundation device than non-vibration. Coated area on artificial leather by liquid foundation wasalso broadened over twice using the vibration, which means that spreadability is improved greatly as well. Measurement of brightness on a spot of artificial leather at fixed interval showed that higher brightness inbroader coating area was maintained when the vibration was operated. Improvement in adhesion ratio andspreadability when vibration was operated, was greater in liquid type foundation than solid powder form. Thedetergency when vibrating cleanser device was used, was improved over twice compared to hand washing.
