ANTIBACTERIAL AGENT AND METHOD OF USING THE SAME
An antibacterial agent of the present invention contains a metal-containing compound containing a metal other than aluminum, and a phosphorus-adsorbing material. A method of using an antibacterial agent of the present invention is a method for improving an antibacterial property of a metal-containing compound containing a metal other than aluminum, wherein the metal-containing compound and a phosphorus-adsorbing compound are used in combination. Thus, the present invention provides an antibacterial agent, and a method of using an antibacterial agent, wherein an antibacterial property of a metal-containing compound containing a metal other than aluminum, particularly a silver-containing compound, is improved significantly.
1 . An antibacterial agent comprising:
a metal-containing compound containing a metal other than aluminum; and
a phosphorus-adsorbing material.
2 . The antibacterial agent according to claim 1 , wherein the metal-containing compound is one or more metal-containing compounds selected from the group consisting of silver-containing compounds, zinc-containing compounds, and copper-containing compounds.
3 . The antibacterial agent according to claim 1 , wherein the metal-containing compound is a silver-containing compound.
4 . The antibacterial agent according to claim 1 , wherein the phosphorus-adsorbing material is an aluminum compound.
5 . The antibacterial agent according to claim 4 ,
wherein the aluminum compound is an aluminum-containing resin that contains a matrix resin component and an aluminum salt,
wherein the matrix resin component is at least one selected from regenerated collagen, polyvinyl alcohol, and carboxymethyl cellulose, and
the aluminum salt is bonded chemically with the matrix component.
6 . The antibacterial agent according to claim 1 , wherein when the antibacterial agent is assumed to be 100 wt %, the metal-containing compound and the phosphorus-adsorbing material account for 0.0001 wt % to 99.9 wt %, and 0.1 wt % to 99.9999 wt %, respectively.
7 . The antibacterial agent according to claim 1 , wherein the phosphorus-adsorbing material is allophane.
8 . A method of using an antibacterial agent for improving an antibacterial property of a metal-containing compound containing a metal other than aluminum, comprising use of the metal-containing compound and a phosphorus-adsorbing compound in combination.
9 . The method of using an antibacterial agent according to claim 8 , wherein the metal-containing compound is one or more metal-containing compounds selected from the group consisting of silver-containing compounds, zinc-containing compounds, and copper-containing compounds.
10 . The method of using an antibacterial agent according to claim 8 , wherein the metal-containing compound is a silver-containing compound.
11 . The method of using an antibacterial agent according to claim 8 , wherein the phosphorus-adsorbing material is an aluminum compound.
12 . The method of using an antibacterial agent according to claim 11 ,
wherein the aluminum compound is an aluminum-containing resin that contains a matrix resin component and an aluminum salt,
wherein the matrix resin component is at least one selected from regenerated collagen, polyvinyl alcohol, and carboxymethyl cellulose, and
the aluminum salt is bonded chemically with the matrix component.
13 . The method of using an antibacterial agent according to claim 8 , wherein when the antibacterial agent is assumed to be 100 wt %, the metal-containing compound and the phosphorus-adsorbing material account for 0.0001 wt % to 99.9 wt %, and 0.1 wt % to 99.9999 wt %, respectively.
14 . The method of using an antibacterial agent according to claim 8 , wherein the phosphorus-adsorbing material is allophane.
