Description

Technical Field

[0001] The present invention relates to a cleaning agent composition for hard surfaces.

Background Art

[0002] Generally, as cleaning agents for hard surfaces, in order to remove different types of dirt on treatment targets such as bathrooms, kitchens, and floors, those with compositions suitable for each are used. For example, as a kitchen cleaner used around the kitchen, such as a range, oven, walls and floor around the range, and exhaust fan, in order to remove oil stains that have deteriorated due to the action of heat, sunlight, oxygen in the air, etc., a cleaning agent containing a surfactant, a solvent, an alkali agent, etc. is used. Also, as a bathroom cleaner used in bathrooms such as bathtubs, bathroom walls and floors, a cleaning agent containing a surfactant, a solvent, a sequestering agent, etc. is used in order to remove dirt of metal soaps, particularly calcium salts of fatty acids.

[0003] There may be cases where it is desired to remove very stubborn oily dirt such as oxidized oil from cleaning agents for hard surfaces. Patent Documents 1 and 2 disclose a hard surface liquid cleaning agent composition containing a specific monoalkyl ether of polyalkylene glycol and having a very high cleaning effect on oxidized oil.

[0004] In addition, detergents for hard surfaces are often used for sinks and walls in the kitchen area. Therefore, cationic bactericides are often added in anticipation of a bactericidal effect. As cationic bactericides, cationic surfactants with bactericidal properties are known. Patent Document 3 discloses a technology for a liquid detergent composition for hard surfaces that contains a cationic surfactant and an arylsulfonic acid, has excellent foaming power and detergency, and has excellent bactericidal efficacy. Patent Document 4 also describes a thickening-effective amount of a rod-shaped micelle thickener composition that contains (a) an amine oxide, a quaternary ammonium compound or a mixture thereof and an anionic counterion, which is sufficient to thicken the detergent composition when diluted in the use solution, (b) a lower alkyl glycol ether solvent in an amount effective for cleaning, (c) an alkalinity source in an amount effective for cleaning, and (d) a hardness sequestering agent in an amount effective for hardness treatment, and a concentrated composition of a thick aqueous detergent that can produce a more viscous use solution effective for cleaning a substantially vertical surface is described.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Hard surfaces are not only susceptible to very stubborn oily stains such as denatured oils, but also to particulate stains such as dust and carbon, and technology is required to remove these at a high level. However, cleaning agents containing cationic bactericides such as cationic surfactants tend to have a significantly reduced cleaning power for particulate stains such as dust and carbon. On the other hand, while it is generally known to disperse / clean such particulate stains using anionic surfactants, the problem of the bactericidal effect being significantly impaired when cationic bactericides are used in combination becomes evident. This problem is particularly evident when a solvent is the main agent for the cleaning effect. The present invention provides a cleaning agent composition for hard surfaces which has a high ability to remove particulate dirt on hard surfaces and has an excellent bactericidal effect. [Means for solving the problem]

Examples of the quaternary ammonium salt include compounds represented by the following general formula (c1).

[0018] [Chemical formula]

[0028] <Composition, optional components, etc. of the cleaning agent for hard surfaces> The present invention relates to a cleaning agent using component (a) as a main cleaning substrate. When a cationic bactericide as component (c) is used, there is a problem that the removability of particulate soil is significantly reduced. The present invention has found that by using component (b) in combination, it is possible to achieve both bactericidal properties and particulate soil detergency. Generally, the surface of particulate soil such as dust and carbon is anionic in water, so component (c) is easily adsorbed, the particles in the soil are hydrophobized / aggregated and the removability is reduced, and moreover, the amount of component (c) that can be effectively used is reduced, resulting in a decrease in the bactericidal effect. In the present invention, by using an organic sulfonic acid having a hydrocarbon group with 1 to 12 carbon atoms or a salt thereof as component (b), it is possible to obtain good detergency against particulate soil while suppressing a decrease in bactericidal performance. Since component (b) has relatively low surfactant performance, it is difficult to adsorb to the particles in the soil. On the other hand, since it is an anionic compound, it is considered that it interacts weakly with component (c) and can suppress the adsorption of component (c) to particulate soil. As a result of such an effective interaction between component (b) and component (c), it is presumed that in the present invention, both bactericidal properties and particulate soil detergency can be achieved.

[0082] 〔Cleaning method〕 The present invention provides a method for cleaning a hard surface, which comprises bringing the cleaning agent composition for a hard surface of the present invention into contact with the hard surface for cleaning.

[0083] The cleaning method of the present invention can be preferably implemented as a method for cleaning a hard surface, which comprises bringing the cleaning agent composition for a hard surface of the present invention into contact with a hard surface to which particulate soil or particulate soil and oily soil (hereinafter, when referring to soil, unless otherwise specified, means soil containing particulate soil or particulate soil and oily soil) adheres. Hereinafter, the method for cleaning a hard surface will be described.

[0084] In the method for cleaning a hard surface of the present invention, the cleaning agent composition for a hard surface is brought into contact with the hard surface. The cleaning agent composition for a hard surface to be brought into contact with the hard surface contains the component (a), preferably 0.1% by mass or more, more preferably 0.5% by mass or more, still more preferably 0.8% by mass or more, even more preferably 1% by mass or more, and preferably 20% by mass or less, more preferably 10% by mass or less, still more preferably 8% by mass or less, even more preferably 5% by mass or less, from the viewpoints of bactericidal property, cleaning property for particulate soil, and cleaning property for oily soil.

Further, the cleaning agent composition for a hard surface to be brought into contact with the hard surface contains the component (b), preferably 0.01% by mass or more, more preferably 0.1% by mass or more, still more preferably 0.3% by mass or more, and preferably 10% by mass or less, more preferably 5% by mass or less, still more preferably 2% by mass or less, from the viewpoint of bactericidal property. Further, the cleaning agent composition for a hard surface to be brought into contact with the hard surface contains the component (c), preferably 0.001% by mass or more, more preferably 0.01% by mass or more, still more preferably 0.1% by mass or more, even more preferably 0.5% by mass or more, and preferably 10% by mass or less, more preferably 5% by mass or less, still more preferably 3% by mass or less, even more preferably 2% by mass or less, from the viewpoint of bactericidal property.

[0085] In the present invention, a concentrated composition containing the component (a), the component (b), and the component (c) may be prepared, and the concentrated composition may be diluted with water to prepare the cleaning agent composition for a hard surface of the present invention, and then brought into contact with the hard surface. That is, it may be a method for cleaning a hard surface in which the concentrated composition containing the component (a), the component (b), and the component (c) of the present invention is diluted with water to prepare the cleaning agent composition for a hard surface of the present invention, and the cleaning agent composition for a hard surface is brought into contact with the hard surface without dilution.

[0086] When targeting dirt with a high particulate dirt load, the cleaning composition for hard surfaces can be brought into direct contact with the object. When targeting dirt with a relatively low particulate dirt load, the cleaning composition for hard surfaces can be further diluted with water and used. When the cleaning composition for hard surfaces is diluted with water and used, in order to obtain a bactericidal effect, it is preferable that the concentration of component (c) in the aqueous dilution is 0.1 ppm or more, more preferably 0.5 ppm or more, and even more preferably 1 ppm or more. This aqueous dilution is also the cleaning composition for hard surfaces of the present invention.

[0087] In the present invention, since it is a composition that exhibits dispersibility with respect to particulate dirt while ensuring the bactericidal property of the cationic bactericide as component (c), it is possible to obtain excellent cleaning and bactericidal effects even on hard surfaces to which dirt containing particulate dirt adheres.

[0088] Further, the method for cleaning a hard surface of the present invention includes a cleaning method in which the cleaning composition for hard surfaces is brought into contact with a hard surface to which dirt has adhered and then left without applying (without imparting) an external force such as mechanical force. In the present invention, since the surfactant adsorbs to dirt and bacteria, and alkalis etc. disperse and decompose dirt, it can be brought into contact without using a flexible material such as a sponge or fingers, and a high cleaning effect and bactericidal effect can be obtained even when left as it is without applying an external force such as mechanical force. Thereby, it is suitable for cleaning parts that are inaccessible to hands or tools and hard-to-reach details. Leaving without applying an external force such as mechanical force means, for example, not performing an intentional operation for cleaning other than the contact of the composition. For example, it can be understood that leaving it without applying an external force when the applied composition naturally flows down the hard surface or when vibrations unintended for cleaning are transmitted to the hard surface. After leaving it, it is usually rinsed with water. When rinsing, an external force (physical force) may be applied with the hand etc., or it may be simply rinsed with a water flow.

In this case, the time when the composition first comes into contact with the hard surface may be taken as the start of leaving it. The temperature during leaving may be room temperature, for example, 10°C or higher and 30°C or lower.

[0091] Also, in the method for cleaning a hard surface of the present invention, from the viewpoint of enhancing the cleaning effect, it is preferably for 10 seconds or more, more preferably 20 seconds or more, still more preferably 30 seconds or more, even more preferably 40 seconds or more, and from the same viewpoint, preferably 60 minutes or less, more preferably 30 minutes or less, still more preferably 20 minutes or less, even more preferably 10 minutes or less, even more preferably 5 minutes or less, the cleaning composition for a hard surface is brought into contact with the hard surface to be cleaned.

[0092] In the method for cleaning a hard surface of the present invention, the cleaning composition for a hard surface may be brought into contact by immersing the hard surface with dirt adhered thereto in the composition, or from the viewpoint of efficiently enhancing the cleaning effect, it may be sprayed or applied to bring it into contact with the hard surface with dirt adhered thereto. The method of bringing the cleaning agent composition for hard surfaces into contact with a hard surface to which dirt has adhered is preferably spraying or coating, and examples thereof include a method of spraying in the form of droplets or applying in the form of foam. Specifically, spray means can be used. That is, it is preferable to use a cleaning agent article for hard surfaces filled with the cleaning agent composition for hard surfaces of the present invention in a container equipped with a sprayer. The present invention provides a cleaning agent article for hard surfaces in a spray container, which is filled with the cleaning agent composition for hard surfaces of the present invention in a container equipped with a sprayer.

The container equipped with the sprayer is preferably a trigger-type spray that can spray or apply the contents in the form of droplets or foam, and more preferably a trigger-type spray equipped with a mechanism for spraying the contents in the form of droplets or a trigger-type spray equipped with a mechanism for forming foam (foam-forming mechanism).

[0094] In the cleaning agent article for hard surfaces in a spray container of the present invention, when using a trigger-type spray equipped with a mechanism for spraying the cleaning agent composition for hard surfaces of the present invention in the form of droplets, the spray hole diameter of the injection nozzle of the spray container containing the composition is preferably 0.1 mm or more, more preferably 0.3 mm or more, and preferably 2 mm or less, more preferably 1 mm or less, in order to facilitate spraying, prevent the sprayed droplets from becoming rough, prevent the spray from being in a straight line, and prevent the spraying area from becoming extremely narrow.

[0099] <Preparation of cleaning agent composition for hard surfaces> To water, each component shown in the table was added in the proportions shown in the table, and the mixture was stirred with a stirrer and held for 10 minutes to prepare a hard surface cleaning agent composition. In the table, for the compositions in which monoethanolamine was not blended, the pH was adjusted with NaOH so that the pH would be 11.5. Also, in the table, for the compositions in which monoethanolamine was blended, the pH was not adjusted. The pH was measured by the glass electrode method.

[0100] <Particle soil detergency test> A 1 cm square cloth (cotton jersey, manufactured by Taniguchi Shoten) was immersed in a particle soil model liquid (the balance being water) containing 0.28% by mass of EP-700 Blue GA (pigment, manufactured by Dainichi Seika Kogyo Co., Ltd.), 0.3% by mass of Liqutint Bright Yellow (pigment, manufactured by Milliken Chemical), and 0.25% by mass of monoethanolamine for 30 seconds and dried overnight to obtain a particle soil contaminated cloth. 5 mL of the hard surface cleaning agent composition shown in the table was placed in a No. 5 screw tube, and one piece of the particle soil contaminated cloth prepared above was placed therein, and the mixture was stirred with a stirrer at 20 °C for 25 minutes. Thereafter, the cloth was taken out and dried overnight, and the a * value was measured using a colorimeter (Spectrophotometer SE 2000, manufactured by Nippon Denshoku Industries Co., Ltd.). The results are shown in Tables 1 to 3. The larger the a * value, the higher the detergency against particle soil, and a value of -16.0 or more is considered acceptable.

[0101] <Sterility test> (1) 10 mL of LB medium was placed in a tissue culture flask, and Staphylococcus aureus cultured in a petri dish was taken out with an inoculation loop and placed in the LB medium. (2) The above flask was placed in a constant temperature shaking incubator (Bio Shaker BR-23FP, manufactured by Taitec Co., Ltd.) and cultured at 200 rpm and 37 °C for 16 hours. (3) The above LB medium was transferred to a 50 mL centrifuge tube and centrifuged at 4000 rpm, 15 °C, and for 10 minutes using a centrifuge (himac CF 9RX, manufactured by Hitachi, Ltd.). (4) Discard the clarified LB medium, add 10 mL of physiological saline, and centrifuge again under the same conditions as in (3). (5) Discard the supernatant physiological saline, add physiological saline, and prepare a bacterial solution with OD1. (6) Using the solution prepared in (5), prepare a bacterial solution with 0.5% BSA and OD0.001. (7) Add 0.3 mL of the bacterial solution prepared in (6) onto a SUS304 plate with dimensions 8 cm × 3 cm × 0.1 cm, and spread it evenly. (8) To the plate in (7), add 0.3 mL of the test solution obtained by diluting the hard surface detergent compositions in Tables 1 and 2 1000-fold with water, spread it evenly, and let it stand for 30 minutes. When using the hard surface detergent composition in Table 3, replace it with the test solution obtained by diluting the said composition 10-fold with water and perform the same operation. Also, as a control, prepare a sample by treating the plate in (7) with water only. (9) Pour the liquid remaining on the plate onto a swab stick sealed with 1 mL of LP stop solution, and swab and wipe the plate with the swab stick. (10) Take out the liquid from the swab stick and serially dilute it 10-fold. (11) Add 0.1 mL of the serially diluted liquid to a standard agar medium, and spread it with a spreader. (12) Incubate the medium prepared in (11) at 37 °C for 24 hours and count the number of colonies. The difference between the viable bacteria count of the control (sample treated with water only) and the viable bacteria count of the samples treated with each composition was taken as the sterilization count [Log(cfu / mL)]. The results were shown in a table. Note that a sterilization count of 0.10 Log(cfu / mL) or more is considered qualified.
