Abstract
An antibacterial cosmetic tool is produced by soaking a base material selected from fiber, yarn, pile fabric, animal hair, wig material, polyurethane sponge and NBR sponge into an aqueous solution containing (A) benzyl ammonium chloride compound and (B) naphthoquinone compound, after which the solution is heated to cause 0.1 to 5.0 percent by weight of (A) benzyl ammonium chloride compound and 0.1 to 5.0 percent by weight of (B) naphthoquinone compound to be adsorbed/contained to/by the material.
Claims17
A method for producing a cosmetic tool having an antibacterial property, comprising:
- providing a solution containing about 1.0% to about 5.0% by weight of (A) benzyl ammonium chloride compound and about 1.0% to about 5.0% by weight of (B) naphthoquinone compound, wherein the benzyl ammonium chloride compound is a lauryl trimethyl ammonium chloride compound or a cetyl dimethyl benzyl ammonium chloride compound, and the naphthoquinone compound is a naphtho[2,3-D]thiazole-4,9-dion compound or a 2,3-dichloronaphthoquinone compound;
- soaking a base material for a cosmetic tool in the solution, said material being selected from the group consisting of raised woven fabric, raised knit fabric, nonwoven pile, flocked fabric, monofilament, animal hair, wig material, polyurethane sponge, and NBR sponge;
- and
- subjecting the base material in the solution to hot solution processing to absorb the compounds (A) and (B) to the base material to provide the base material with an antibacterial halo width of 5 mm or more maintained after hand wash.
A cosmetic tool having an antibacterial property with an antibacterial halo width of 5 mm or more maintained even after hand wash by rubbing, produced by causing 1.0% to about 5.0% by weight of (A) benzyl ammonium chloride compound and about 1.0% to about 5.0% by weight of (B) naphthoquinone compound to be adsorbed, through hot solution processing, to the cosmetic tool, wherein the benzyl ammonium chloride compound is a lauryl trimethyl ammonium chloride compound or a cetyl dimethyl benzyl ammonium chloride compound, and the naphthoquinone compound is a naphtho[2,3-D]thiazole-4,9-dion compound or a 2,3-dichloronaphthoquinone compound.
A method for producing a cosmetic tool having an antibacterial property with an antibacterial halo width of 5 mm or more maintained even after hand wash by rubbing, characterized by soaking the cosmetic tool in an aqueous solution containing (A) benzyl ammonium chloride compound and about (B) naphthoquinone compound, and applying hot solution processing, wherein the benzyl ammonium chloride compound is a lauryl trimethyl ammonium chloride compound or a cetyl dimethyl benzyl ammonium chloride compound, and the naphthoquinone compound is a naphtho[2,3-D]thiazole-4,9-dion compound or a 2,3-dichloronaphthoquinone compound.
