JP7365768B2 - Acidic disinfectant composition and method for enhancing disinfectant efficacy - Google Patents

Description

The present invention relates to an acidic sterilizing composition comprising an acid as a sterilizing component in an aqueous solution, and a method for enhancing the sterilizing efficacy of the acidic sterilizing composition.

Among the dirt that adheres to tiles, joints, and plastics in bathrooms, toilets, kitchens, etc., there is dirt and slime caused by bacteria and mold. Such stains caused by bacteria and mold can be prevented by sterilizing them on a daily basis with a liquid detergent containing hypochlorite as the main ingredient. However, hypochlorous acid preparations generate dangerous chlorine gas when mixed with acidic bleach, etc., so their use should originally be restricted, but there are no other products to replace them. It is still widely used today. Under these circumstances, there is a demand for cleaning agents that are both highly safe and highly sterilizing.

Therefore, various water-based cleaning agents containing acids as disinfectant ingredients have been proposed. For example, U.S. Pat. No. 5,000,300 discloses a dilutable acid disinfectant concentrate composition comprising a disinfectant-effective fatty acid, a hydrotrope-solubilizer, a strong acid, and an ingredient that provides a composition with increased stability. A disinfectant cleaning composition for hard surfaces is disclosed in which the chemical component contains a weak acid selected from the group consisting of propionic acid, butyric acid, and valeric acid, and mixtures thereof. It is also described that alkanesulfonates such as sodium 1-octanesulfonate and sodium 1,2-octanedisulfonate are used as hydrotropes.

Further, Patent Document 2 discloses that at least one aliphatic short-chain antibacterially effective C5 to C14 fatty acid or a mixture thereof, at least one carboxylic acid-based weak acid, and nitric acid or nitric acid and phosphorus. Disinfectant compositions are disclosed that include a mixture of acids, a strong mineral acid. The incorporation of at least one organic hydrotrope is also described.

Hereinafter, the acidic disinfectant composition of the present invention will be explained in detail. The acidic disinfectant composition of the present invention comprises (A) an organic acid or phosphoric acid as a disinfectant component, and (B) an aromatic sulfonic acid having 7 to 9 carbon atoms as a disinfectant efficacy enhancing component that enhances the disinfectant efficacy of the disinfectant component. A salt is mixed with (C) water to form an aqueous solution.

As the sterilizing component added to the acidic sterilizing composition of the present invention, organic acids or phosphoric acid may be mentioned. Preferred organic acids are citric acid, acetic acid, lactic acid, malic acid, succinic acid, adipic acid, and fumaric acid. These acids may be used alone or in combination of two or more. Particularly preferred is fumaric acid, which has a high bactericidal effect as a compound and also has a remarkable bactericidal effect enhancing effect due to its bactericidal efficacy enhancing component.

Although the amount of the bactericidal component in the acidic bactericidal composition of the present invention is not particularly limited, in order to obtain a sufficient bactericidal effect, as shown in the Examples below, the amount of the bactericidal component added to the entire acidic bactericidal composition must be 0. It is preferable to blend 0.01% by mass or more.

The aromatic sulfonate having 7 to 9 carbon atoms, which is blended into the acidic disinfectant composition of the present invention, is used as a bactericidal efficacy-enhancing component that improves the bactericidal efficacy of organic acid or phosphoric acid, which is a bactericidal component. Aromatic sulfonates have a hydrophilic group and a lipophilic group in their molecules, and have the property of dissolving other organic compounds in water or an aqueous salt solution at a high concentration. It has not been known to take advantage of this property to incorporate aromatic sulfonates as hydrotrope agents that prevent changes in viscosity due to temperature changes and precipitation of organic compounds by increasing their solubility in water. However, it was discovered for the first time by the present inventors that aromatic sulfonate acts as a component that enhances the bactericidal efficacy of organic acids or phosphoric acid.

Specific examples of aromatic carboxylic acid salts having 7 to 9 carbon atoms to be incorporated into the acidic disinfectant composition of the present invention include sodium o-xylene sulfonate, sodium m-xylene sulfonate, sodium o-toluenesulfonate, Examples include sodium m-toluenesulfonate, sodium p-toluenesulfonate, sodium m-cumenesulfonate, sodium p-cumenesulfonate, and sodium mesitylenesulfonate. These aromatic sulfonates may be used alone or in combination of two or more.

Among sodium xylene sulfonates, sodium m-xylene sulfonate is preferred.

Although the amount of aromatic sulfonate in the acidic disinfectant composition of the present invention is not particularly limited, if the amount is too small, the bactericidal effect of the organic acid and phosphoric acid, which are the bactericidal ingredients, may not be sufficiently enhanced. There is sex. As shown in the Examples below, it is preferable to blend the aromatic sulfonate in an amount of 0.1% by mass or more based on the entire acidic disinfectant composition.

A surfactant may be added to the acidic disinfectant composition of the present invention depending on the purpose. For example, a surfactant is added when the solubility of the aromatic sulfonate to be added as a bactericidal efficacy enhancing ingredient in water is not so high and it is desired to increase the amount of the aromatic sulfonate added. In addition, surfactants have the property of generating foam (foaming properties), and by using a surfactant with excellent foaming properties, the acidic disinfectant composition of the present invention can be sprayed onto a wall using a trigger spray or the like. This suppresses liquid dripping and makes it easier to visually recognize the applied area.

Unlike general anionic surfactants, aromatic sulfonate, which is blended as a bactericidal efficacy enhancing ingredient, does not impair foam breakage even when used in combination with nonionic surfactants. Furthermore, even if it coexists with a cationic surfactant, precipitation is unlikely to occur. Therefore, any of anionic surfactants, cationic surfactants, nonionic surfactants, and amphoteric surfactants can be suitably used as the surfactant to be incorporated into the acidic disinfectant composition of the present invention. Although the amount of surfactant in the acidic disinfectant composition of the present invention is not particularly limited, it is preferably 0.1% by weight or more and 10% by weight or less.

Examples of anionic surfactants include fatty acid soaps, alkylbenzene sulfonates, linear alkylbenzene sulfonates, alkyl sulfates, α-olefin sulfonates, alkyl phosphate ester salts, polyoxyethylene alkyl ether sulfates, Examples include polyoxyethylene alkyl phenyl ether sulfate and polyoxyethylene alkyl ether phosphate.

Examples of cationic surfactants include quaternary ammonium salts such as lauryltrimethylammonium chloride and benzalkonium chloride.

Examples of nonionic surfactants include polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene higher fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester, and polyoxyethylene hydrogenated castor oil. , coconut oil fatty acid diethanolamide, polyoxyethylene polyoxypropylene alkyl ether, fatty acid alkanolamide, alkylamine oxide, and the like.

Examples of amphoteric surfactants include betaine type surfactants. Specific examples thereof include lauryl-N,N-dimethylacetic acid betaine, laurylamidepropyl-N,N-dimethylacetic acid betaine, coconut alkylamidepropyl-N,N-dimethylhydroxypropylsulfobetaine, and the like.

The acidic disinfectant composition of the present invention is an aqueous type, and water is mainly used as the solvent. Examples of water include purified water such as ion-exchanged water and reverse osmosis water, ordinary tap water, industrial water, and deep ocean water.

Furthermore, the acidic disinfectant composition of the present invention may contain other components such as an inorganic antibacterial agent, an organic antibacterial agent, an algae preventive agent, a rust preventive agent, a solvent, a chelating agent, a fragrance, a deodorizing component, etc., as necessary. By blending within a range that does not impair the effects of the present invention, antibacterial effects, algae-proofing effects, rust-preventing effects, cleaning effects, aromatic properties, deodorizing properties, etc. may be imparted.

Bacteria and mold can be effectively removed by applying or spraying the thus obtained acidic disinfectant composition of the present invention to areas where bacteria and mold are likely to grow, such as kitchen and bathroom drains and tile joints. be able to. The acidic disinfectant composition of the present invention is extremely practical because it can be applied safely and easily, unlike hypochlorous acid preparations, which are dangerous and difficult to handle.

In addition, the acidic disinfectant composition of the present invention contains an organic acid such as citric acid, acetic acid, lactic acid, malic acid, succinic acid, adipic acid, or fumaric acid or phosphoric acid as a disinfecting component, and a specific aroma as a disinfecting effect enhancing component. It has a very simple composition, just adding a group sulfonic acid compound to water. Therefore, it is easy to manufacture, has minimal skin irritation, which is a problem with many disinfectants, and is extremely safe.
