2. 1. Introduction of Powder Coating Features of Powder : As most inorganic pigments have hydrophilic properties, when they are applied to makeup products, it happens that makeup is erased easily depending on sweat, sebum, foreign environment conditions. Also, as inorganic pigments have the same property as abrasives, they provide skin with coarse touch To improve this disadvantage, diverse coating agents and coating methods have been introduced.
