摘要： The antibacterial paper of the present invention contains an antibacterial agent, and the calcium content per 0.1 g of the antibacterial paper is 500 ppm or more. A method for manufacturing an antibacterial paper of the present invention includes a papermaking step of forming a wet paper web by wet papermaking using a papermaking water having a Water hardness of 5° dH or more, an antibacterial agent applying step of applying an antibacterial agent-containing liquid prepared from an antibacterial agent and a dilution water thereof to the wet paper web, and a drying step of heating and drying the wet paper web after undergoing the antibacterial agent applying step. The Water hardness of the dilution water is equal to or less than the Water hardness of the papermaking water.

摘要： A water-soluble cationic polymer is applied to a sanitary product. The water-soluble cationic polymer has a structure including a main chain and a side chain bound to the main chain and has a molecular weight of 2000 or more. The water-soluble cationic polymer is a quaternary ammonium salt homopolymer or a quaternary ammonium salt copolymer. In the water-soluble cationic polymer, the main chain and the side chain are bound to each other at one point, and the side chain has a quaternary ammonium moiety. It is preferable that the quaternary ammonium salt homopolymer has a molecular weight of ten million or less. It is preferable that the quaternary ammonium salt copolymer is a copolymer of a polymerisable monomer having a quaternary ammonium moiety and a cationic polymerisable monomer, an anionic polymerisable monomer, or a nonionic polymerisable monomer, and has a molecular weight of ten million or less.
