PROBLEM TO BE SOLVED: To provide an anti-bacterial make-up brush, sanitary and safe, and exhibiting anti-bacterial performance over a long period of time while protecting the global ecology environment. SOLUTION: This anti-bacterial make-up brush is a make-up brush whose brush bristles are formed of synthetic fibers. The brush bristles contain 20 pts.wt. synthetic fiber containing an inorganic antimicrobial agent in 100 pts.wt. brush bristles, and the synthetic fiber containing the inorganic antimicrobial agent contains 0.02-3 pts.wt. inorganic anti-bacterial agent in 100 pts.wt. In manufacturing this make-up brush, 30-1 pts.wt. inorganic antimicrobial agent is mixed with 70-90 pts.wt. resin of one kind selected from thermoplastic resins, molten and dispersed. After that, a master batch is manufactured by extrusion molding, and subsequently the master batch is mixed with thermoplastic raw material resin, molten and dispersed. After that, the mixture is subjected to spinning to thereby make a brush bristle. The master batch is mixed so that 0.02-3 pts.wt. inorganic antimicrobial agent is contained in 100 pts.wt. brush bristle. COPYRIGHT: (C)2010,JPO&INPIT |
