Abstract

This study is intended to analyze the impact of PMMA on color changes comparatively by making 2 types of cheek color items with red-color pigments: one containing PMMA, which is one of the recently developed circular polymers and used when producing color make-up items that have aero powder as the chief ingredient, and the other without it. To accomplish the purpose, we have reviewed literature on raw materials that have aero powder as the chief ingredient. Also, after making compounds of PMMA and pigments lot aero powder, such as Talc, Mica, OMC Talc As, Mica As, we examined them compared to those without PMMA using spectrophotometer, a questionnaire survey, and Digital camera. Besides, the particles were analyzed using SEM. As a result of the analysis, cosmetics containing PMMA represent more vivid and rich colors, putting on one’’s face softly. Since the entire specific surface area of PMMA is large enough to absorb oil evenly, it yields vivid and rich colors. But, Mica, one of natural pigments, shows a result as opposed to that of Mica As, one of silicon-compounded pigments, suggesting that pearl effect may possibly causes defused reflection. Based on these findings, it is expected that cosmetics will have more vivid colors, or improved color presentation, as well as the softer sense of touch when a circular polymer of PMMa is added to the manufacturing process of color make-up items.
