Description

[Technical Field]

[0001] This invention relates to a cleaning agent composition for hard surfaces. [Background technology]

[0002] In kitchens and kitchen sinks, stovetops, range hoods, and microwave ovens, oil fumes generated during daily cooking operations adhere to hard surfaces such as walls and countertops. These stains can be removed using conventional degreasing detergents if they have been there for about a week. For example, Patent Document 1 states (a) Monoalkyl ethers of polyalkylene glycols, (b) Amine oxide, (c) Contains one or more fatty acids and their salts having 8 to 18 carbon atoms, and water. A cleaning agent composition for hard surfaces is disclosed, having a pH of 8 to 14 at 25°C. [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2012-126883 [Overview of the project] [Problems that the invention aims to solve]

[0004] Oil stains originating from such grease and smoke, after about a week or more, are modified and polymerized by the action of heat, sunlight, indoor light, oxygen, etc. (hereinafter referred to as modified oil stains), making them difficult to completely remove with conventional cleaning agents. Furthermore, using stronger inorganic alkaline agents or hypochlorites may raise safety and odor issues. Therefore, there is a strong need for a detergent composition that can remove modified oil stains simply and efficiently. [Means for solving the problem]

[0005] As a result of intensive studies to solve the above problems, it has been found that by using a composition containing an alkanolamine and two solvents having different LogP (octanol / water partition coefficient), higher detergency can be exhibited. Further, it has been found that by swelling the denatured oil stain with the above composition, the denatured oil stain can be peeled off from the hard surface without rubbing with a strong physical force, and it has become easy to remove, thus completing the present invention. That is, the present invention relates to (a) component: a glycol monoalkyl ether-based solvent having an oxyalkylene group having 2 and / or 3 carbon atoms and having a LogP of less than 0 ((a-1) component), and a solvent having a LogP of 0 or more and 1.5 or less ((a-2) component), in total 1% by mass or more and 15% by mass or less, (b) component: alkanolamine 0.5% by mass or more and 10% by mass or less, and containing water, the mass ratio of the (a-1) component to the (a-2) component, [(mass of the (a-1) component) / (mass of the (a-2) component)], is 0.05 or more and 10 or less, and a pH at 25° C. of 8 or more and 13 or less, a cleaning agent composition for a hard surface. Further, the present invention relates to a cleaning agent article for a hard surface, which is filled with the cleaning agent composition for a hard surface in a trigger-type spray provided with a mechanism for spraying the contents in a liquid-drop or foamy state. Furthermore, the present invention relates to a method for cleaning a hard surface, which applies the cleaning agent composition for a hard surface to a denatured oil stain on the hard surface for cleaning.

Effects of the Invention

[0006] According to the present invention, by using the cleaning agent composition for a hard surface of the present invention, it is possible to simply and efficiently clean a denatured oil stain that is difficult to remove with a conventional cleaning agent. The cleaning agent composition for a hard surface of the present application is particularly effective for denatured oil stains, but is also similarly effective for oil stains before denaturation. In this specification, for the sake of convenience, the mode for denatured oil stains is shown, but it can be applied in the same mode to oil stains before denaturation.

Modes for Carrying Out the Invention

[0007] Although the reason why the cleaning agent composition for hard surfaces and the hard surface cleaning method of the present invention have an extremely high cleaning effect on denatured oil stains that are difficult to remove is not necessarily clear, it is presumed as follows. By using a composition containing two solvents with different LogP (octanol / water partition coefficients) in the presence of alkanolamine, the denatured oil stains are swollen, and the penetration of alkanolamine, which is an active ingredient for decomposing and cleaning oil, into the denatured oil stains is promoted. Thus, it is推测 that the denatured oil stains are peeled off from the hard surface without relying on a physically strong force, making it easy to remove.

[0008] <Solvent with LogP less than 0 ((a-1) component)> The cleaning agent composition for hard surfaces of the present invention contains a solvent ((a-1) component) with a LogP less than 0. Here, LogP is the partition coefficient when using octanol / water as a solvent. The LogP value indicates that, with 0 as the boundary value, the larger the positive value, the more hydrophobic and the more distributed by octanol than water, and the larger the negative value, the more hydrophilic and the more distributed by water than octanol. That is, a solvent with a LogP less than 0 is a hydrophilic solvent that is more distributed by water than octanol. The LogP value in the present invention is calculated by a known calculation method. Also, LogP may use a value obtained by calculation using commercially available software or the like using a quantitative structure-activity correlation algorithm. Commercially available software capable of calculating LogP by calculation includes ChemdrawPro, etc.

While cleaning by scrubbing with a sponge or the like can be laborious, the cleaning method of the present invention provides a cleaning method that requires less scrubbing force. Furthermore, sponges can become soiled with modified oil stains. To clean a sponge soiled with modified oil, one can apply a hard surface cleaning agent to the soiled sponge and rinse it with water. However, from the viewpoint of reducing labor burden and increasing water usage, a cleaning method that does not use a sponge is preferable. In other words, the hard surface cleaning agent composition of the present invention can be applied to a hard surface soiled with modified oil by spraying or the like, and left for 30 seconds to 10 minutes or less, providing a cleaning method that allows cleaning simply by rinsing with water without applying force. In addition, the hard surface cleaning agent composition of the present invention can be applied to a hard surface soiled with modified oil by spraying or the like, and the time between scrubbing with a sponge or rinsing with water can be shortened.

[0052] Dodecyldimethylamine oxide (manufactured by Kao Corporation) and dimethyllaurylamine oxide (manufactured by Kao Corporation) were used as surfactants. In addition, the following compounds were used as disinfectants. C12-16 Benzalkonium Chloride (manufactured by Kao Corporation) Citric acid (manufactured by Qingdao Fuso Refining and Processing Co., Ltd.) Benzyl alcohol (manufactured by Valtris Specialty Chemicals (HQ)) Phenoxyethanol (manufactured by Yokkaichi Synthetic Co., Ltd.) Phenyldiglycol (manufactured by Nippon Emulsifier Co., Ltd.) As a water-soluble solvent, 3-methoxy-3-methyl-1-butanol (manufactured by Kuraray Co., Ltd.) or ethanol (manufactured by Nippon Alcohol Industry Co., Ltd.) was used.

[0053] <Measurement of swelling rate of oil stains using glycol monoalkyl ether solvents> A test solution was prepared by mixing 100g of monoethanolamine with 100g of a monoalkyl ether solvent of glycols. 10 μL of rapeseed oil was dropped onto a Teflon plate, heated at 180°C for 10 hours, and then left overnight to cool completely. The dried, plate-like rapeseed oil was transferred to a screw-top tube, 500 μL of the test solution was added, and it was allowed to stand for 5 minutes. The swelling rate was calculated using the following formula. Swelling rate = [(Area of ​​plate-shaped rapeseed oil 5 minutes after adding test solution) ÷ (Area of ​​plate-shaped rapeseed oil before adding test solution)] × 100 (%) The higher the swelling rate, the more the oil stain swells, making it easier to remove from the hard surface. The results are shown in Table 1.

[0054] [Table 1]

[0055] Example 1, which used a mixture of components (a-1) and (a-2), showed a high swelling rate of 115%. On the other hand, Comparative Examples 1 and 2, which used only component (a-2) with a LogP of 0 or more and 1.5 or less, and Comparative Example 3, which used only component (a-1) with a LogP of less than 0, showed swelling rates of 104-107%. These results suggest that using a mixture of components (a-1) and (a-2) makes oil stains more fluid and easier to remove from hard surfaces.

[0056] <Evaluation of cleaning power of cleaning agent compositions for hard surfaces> A hard surface cleaning agent composition having the composition shown in Table 2 was prepared using propylene glycol monomethyl ether (PM) as component (a-1), diethylene glycol monobutyl ether (DEB) as component (a-2), monoethanolamine as component (b), and dodecyltrimethylamine oxide as a surfactant.

[0057] SUS substrate (2.5 x 7.0 cm) 2 70 μL of rapeseed oil was applied to the substrate, heated at 180°C for 1 hour, and then left overnight to cool completely. 1 mL of a hard surface cleaning agent composition was sprayed onto the cooled SUS substrate and left to stand for 5 minutes, after which it was thoroughly rinsed with deionized water. The remaining rapeseed oil was visually observed, and the oil stain removal rate was evaluated as follows, which was defined as the cleaning power. 3: Removal rate of 90% or more 2: Removal rate 80% or more but less than 90% 1: Removal rate 50% or more but less than 80% The results are shown in Table 2.

[0058] [Table 2]

[0059] In Example 2, which used a combination of components (a-1) and (a-2) in a mass ratio of 0.63, good cleaning power was observed. In Comparative Example 4, which used only component (a-2), and Comparative Example 5, which used only component (a-1), the cleaning power was low.
