Abstract: A production method of silver nanowires exhibits a yield enhancement effect for a protective agent other than PVP. The method for producing silver nanowires includes depositing a silver linear structure, which is referred to as silver nanowires, in an alcohol solvent having a silver compound, a halogen compound, and an organic protective agent dissolved therein. A deposition reaction of silver is performed in a state where aluminum nitrate is further dissolved in the solvent, the total amount of aluminum nitrate dissolved in the solvent being from 0.01 to 0.50 in terms of Al/Ag molar ratio with respect to the total amount of the silver compound. The organic protective agent is, for example, one containing one or more kinds of alkylated PVP and a PVP-PVA graft copolymer.

Abstract: A hair applicator comprises a body, a flexible member, and a means of transferring a center of the flexible member. The flexible member comprises bristles, which may be arranged in a circular pattern and/or of differing lengths. A user applies an appropriate amount of hair coloring composition within the bristles of the flexible member. When the center of the flexible member is moved, the shape of the flexible member is changed which causes the bristles to form a conical shape which may be used to grasp strands of hair. The user combs the hair coloring composition throughout the length of the hair to effectively highlight the desired hair strands.
