Dental irrigant
An irrigant comprising either a hypochlorite compound or a chlorhexidine compound in combination with at least one surfactant and preferably two or more surfactants, including fluorosurfactants, ethoxylates, sulfonates, quaternary ammonium compounds, amine oxides, and combinations thereof, wherein each of the surfactants are capable of complexing with one another.
1. A stable irrigant and disinfectant solution that does not gel or clot, the stable solution obtained in a process comprising the steps of:
combining an ethoxylate surfactant with water and agitating to provide a first mixture;
adding to the first mixture an alkyl polyglucoside surfactant and agitating to provide a second mixture;
adding to the second mixture a fluorosurfactant and agitating to provide a tertiary surfactant system;
adding to the tertiary surfactant system an aqueous solution comprising a chlorhexidine-based compound in a form selected from the group consisting of a gluconate, an acetate, and a hydrochloride, to form a complex with one another;
adding to the complex of the surfactant and the chlorhexidine-based compound a chelating agent in an amount that does not form a white precipitate of flocculant, the chelating agent selected from the group consisting of ethylenediaminetetracetic acid (EDTA) and citric acid, and agitating to obtain the stable irrigant and disinfectant solution,
wherein in the irrigant and disinfectant solution the chlorhexidine based-compound is provided at about 0.1-20.0 weight percent , the ethoxylate surfactant is provided at about 0.1-2.0 weight percent, the alkyl polyglucoside is provided at about 0.1-2.0 weight percent, and the fluorosurfactant is provided at about 0.01-2.0 weight percent.
2. The irrigant and disinfectant solution according to claim 1 comprising, by weight percent, the chlorhexidine- based compound at about 0.1-4.0% .
3. The irrigant and disinfectant solution according to claim 1 wherein said chlorhexidine-based compound comprises chlorhexidine gluconate.
4. The irrigant and disinfectant solution according to claim 1 wherein the chelating agent comprises EDTA.
5. The irrigant and disinfectant solution according to claim 1 wherein the chelating agent comprises citric acid.
6. The irrigant and disinfectant solution according to claim 4 , wherein the EDTA is provided at about 1% by weight of the irrigant and disinfectant solution.
7. The irrigant and disinfectant solution according to claim 5 , wherein the citric acid is provided at about 2% by weight of the irrigant and disinfectant solution.
8. The irrigant and disinfectant solution according to claim 1 wherein the ethoxylate surfactant comprises an alkylphenol, phenol, or alcohol ethoxylate surfactant.
