Description

[Technical Field]

[0001] The present invention relates to a deodorizing composition, a deodorizing method, and a deodorizing wipe. [Background technology]

[0002] When shoes are worn, sweat and body heat create an environment in which bacteria can grow inside the shoes, producing the bacterial metabolites valeric acid and isovaleric acid, which cause odor. While this odor is typically eliminated with spray deodorizers, this is not a fundamental solution. Therefore, there is a strong demand for technology that can prevent odor by suppressing bacterial growth and fundamentally eliminating the cause of odor.

[0003] Patent Document 1 discloses a technology for a disinfectant composition containing a quaternary ammonium salt that is effective against various bacteria present in the environment and bacteria normally present on the skin, and describes the use of a nonionic surfactant in combination. Patent Document 2 discloses a technology for a fabric deodorizer containing a cationic surfactant and a nonionic surfactant. Patent Documents 3 and 4 disclose techniques for cleaning sheets with excellent antifungal properties, and disclose techniques that use a quaternary ammonium salt surfactant and a nonionic surfactant in combination.

[0005] However, when these technologies are applied to deodorizers for shoes and other items containing highly water-repellent and hydrophobic materials, there is a problem in that the deodorizing effect is insufficient. While it is possible to improve the deodorizing effect by increasing the concentration of the cationic surfactant, taking into account factors such as skin irritation, a technology that provides excellent deodorizing effect even at low concentrations of the cationic surfactant is required.

[0006] The present invention provides a deodorizing composition, a deodorizing method, and a deodorizing wipe that have excellent deodorizing effects even when a cationic surfactant is contained in a low concentration. [Means for solving the problem]

[0007] The present invention relates to a deodorant composition containing (a) a cationic surfactant [hereinafter referred to as component (a)], and (b) a nonionic surfactant having an HLB of less than 12.5 as determined by the Griffin method [hereinafter referred to as component (b)], and water, wherein the mass ratio (b) / (a) of the content of component (a) to the content of component (b) is 0.4 or more and 5.0 or less.

[0008] The present invention also relates to a deodorizing method in which the deodorizer composition is brought into contact with an object.

[0009] The present invention also relates to a deodorizing wipe comprising the deodorizing composition and a nonwoven fabric.

[0010] The present invention also relates to a microbicidal composition containing component (a), component (b), and water, in which the mass ratio (b) / (a) of the content of component (a) to the content of component (b) is 0.4 or more and 5.0 or less.

[0011] The present invention also relates to a disinfectant composition containing component (a), component (b), and water, in which the mass ratio (b) / (a) of the content of component (a) to the content of component (b) is 0.4 or more and 5.0 or less. [Effects of the Invention]

[0026] [(b) component] Component (b) of the present invention is a nonionic surfactant having an HLB value of less than 12.5 as determined by the Griffin method.

[0027] In the case of a nonionic surfactant having a polyoxyethylene group, the HLB of the component (b) can be determined by the Griffin method represented by the following general formula (1). HLB value = [(molecular weight of the polyoxyethylene group portion of component (b)) / (molecular weight of component (b))] × 20 (1) The molecular weight of the polyoxyethylene group portion of component (b) is calculated using the average number of moles of polyoxyethylene groups added.

[0028] The HLB of component (b) is preferably 8 or more and less than 12.5, preferably 12 or less, more preferably 11 or less, and even more preferably 10 or less, from the viewpoint of bactericidal activity when coexisting with a cationic surfactant and wettability to a target surface.

[0029] From the viewpoint of wettability and cleanability of the target surface, the component (b) is preferably a nonionic surfactant having an HLB of less than 12.5 and containing an alkyleneoxy group (including an ethyleneoxy group).From the viewpoint of wettability and cleanability of the target surface, the nonionic surfactant having an HLB of less than 12.5 and containing an alkyleneoxy group is preferably a nonionic surfactant represented by the following general formula (b1) and having an HLB of less than 12.5. R 1b (CO) m O-(A 1b O) n -R 2b (b1) [In the formula, R 1b is an aliphatic hydrocarbon group having 8 to 16 carbon atoms, and R 2b is a hydrogen atom or a methyl group. CO is a carbonyl group, and m is the number 0 or 1. A 1b The O group is an alkyleneoxy group containing an ethyleneoxy group and having 2 to 4 carbon atoms. n is the average number of moles added and is a number of 1 to 8.

[0030] In general formula (b1), R 1b is an aliphatic hydrocarbon group having 8 to 16 carbon atoms. 1b If the other chemical structures are the same, R 1b The larger the carbon number, the lower the HLB value. 1b The number of carbon atoms is 8 or more, preferably 10 or more, more preferably 12 or more, and 16 or less, preferably 14 or less, from the viewpoint of wettability and cleanability of the object.

In general formula (b1), if the chemical structure other than n is the same, the larger the number of n, the higher the HLB value, and the smaller the number of n, the lower the HLB value. From the viewpoint of bactericidal activity and solubility in the presence of a cationic surfactant, n is 1 or more, preferably 2 or more, more preferably 3 or more, and 8 or less, preferably 6 or less, more preferably 5 or less, and even more preferably 4 or less.

[0033] [Composition, etc.] While shoe soles are made of water-repellent materials such as urethane, they also have the property of absorbing sweat and other substances. This causes bad odors caused by bacteria to be generated from the inside, and the deodorizing effect of ordinary deodorizers does not last long. For this reason, a method of preventing the generation of bad odors using disinfectants is desired. Cationic surfactants are powerful disinfectants, but they are difficult to adhere uniformly to water-repellent materials, and the disinfectant effect does not spread to the entire target surface, especially on hydrophobic surfaces with a surface free energy of 40 Nm / m or less, resulting in the problem of not being able to achieve a satisfactory deodorizing effect. It is conceivable to use a surfactant other than component (b) of the present invention in combination with the cationic surfactant in order to ensure uniform adhesion, but this not only results in a worsening of the feel of the product in contact with the skin, such as foaming or sliminess, but also reduces the bactericidal effect of the cationic surfactant. In this invention, the use of a low-HLB nonionic surfactant not only allows the cationic surfactant to be spread evenly, but also enhances its bactericidal effect, making it possible to achieve a high deodorizing effect even when using a low concentration of cationic surfactant. Although the mechanism of action is unknown, it is presumed that the mixed micelles of the low-HLB nonionic surfactant and the cationic surfactant improve the wettability of the cationic surfactant to hydrophobic surfaces with a surface free energy of 40 Nm / m or less, allowing for even spreading, and that the low-HLB nonionic surfactant acts on the bacterial surface, improving the bactericidal effect of the cationic surfactant.

[0034] From the viewpoint of bactericidal and deodorizing properties, the deodorant composition of the present invention contains component (a) in an amount of preferably 0.05% by mass or more, more preferably 0.1% by mass or more, even more preferably 0.2% by mass or more, and preferably 5% by mass or less, more preferably 2% by mass or less, even more preferably 1% by mass or less, and still more preferably 0.5% by mass or less. In the present invention, the mass of component (a) is calculated by converting the anion, which is the counter ion, into chloride ions.

[0035] The deodorizer composition of the present invention contains component (b) in an amount of preferably 0.1% by mass or more, more preferably 0.2% by mass or more, even more preferably 0.3% by mass or more, and preferably 5% by mass or less, more preferably 2% by mass or less, even more preferably 1% by mass or less, and even more preferably 0.8% by mass or less, from the viewpoints of wettability and cleansing properties for the object, and bactericidal and deodorizing properties due to the coexistence with a cationic surfactant.

[0036] In the deodorant composition of the present invention, the mass ratio (b) / (a) of the content of component (a) to the content of component (b) is, from the viewpoint of the synergistic effect of bactericidal and deodorizing properties, 0.4 or more, preferably 0.8 or more, more preferably 1 or more, even more preferably 1.5 or more, still more preferably 2 or more, and is 5 or less, preferably 4 or less, more preferably 3.5 or less, and even more preferably 3 or less.

[0037] In the deodorant composition of the present invention, from the viewpoint of bactericidal and deodorizing properties, the total mass of the content of component (a) and the content of component (b) is preferably 0.1 mass% or more, more preferably 0.2 mass% or more, even more preferably 0.3 mass% or more, still more preferably 0.4 mass% or more, still more preferably 0.5 mass% or more, and preferably 5 mass% or less, more preferably 3 mass% or less, even more preferably 2 mass% or less, and still more preferably 1.6 mass% or less.

[0038] The deodorant composition of the present invention may contain a nonionic surfactant other than component (b) [hereinafter referred to as component (b')], but care must be taken as this may impair the effects of the present invention. When the HLB of component (b') is determined by Griffin's method, the deodorant composition of the present invention may contain component (b') so that the HLB of the mixed surfactant of components (b) and (b') is preferably 17 or less, more preferably 15 or less, and even more preferably less than 12.5, and 8 or more, from the viewpoint of bactericidal and deodorizing properties. It should be noted that the HLB of the mixed surfactant is additive. Furthermore, when the deodorant composition of the present invention contains component (b'), which cannot be determined by Griffin's method, the HLB of the mixed surfactant of components (b) and (b') can be calculated from the HLB of component (b') experimentally determined as follows. A surfactant with a known HLB determined by Griffin's method is combined with component (b') to emulsify oils and fats with known HLB and water, and the mixture with the best emulsified state is selected, and the HLB can be calculated using formula (I). {(W u ×HLB u )+(W a ×HLB a )} / (W u +W a )=HLB0(I) [Where, W u : (b') Mass fraction of component, W a : Mass fraction of surfactant with known HLB, HLB u : HLB of surfactants with unknown HLB, HLB a :HLB is the HLB of a known surfactant, and HLB0:HLB is the HLB of a known oil or fat.

Examples of component (e) include anionic surfactant (e1) [hereinafter referred to as component (e1)] and amphoteric surfactant (e2) [hereinafter referred to as component (e2)].

Furthermore, when component (e1) is contained in the deodorant composition of the present invention, the mass ratio (a) / (e1) of the content of component (a) to the content of component (e1) is preferably 5 or more, preferably 10 or more, and more preferably 100 or more, in order to obtain a high deodorizing effect. Care must be taken when using component (e2) in terms of the feel of the treated surface. Component (e2) is a foaming surfactant that can cause an undesirable feel, such as a slimy feel, on the surface after treatment. Therefore, when used, the content of component (e2) in the deodorant composition of the present invention is 1% by mass or less, preferably 0.5% by mass or less, and more preferably 0.1% by mass or less.

[0040] In the deodorant composition of the present invention, the total content of the components (a) and (b) in all surfactants is preferably 50% by mass or more, more preferably 60% by mass or more, even more preferably 70% by mass or more, still more preferably 80% by mass or more, still more preferably 90% by mass or more, and is 100% by mass or less, and may be 100% by mass.

[0056] It is believed that cationic surfactants cannot be uniformly adsorbed on such hydrophobic surfaces. Furthermore, in order to achieve uniform adsorption of cationic surfactants, methods for improving the wettability of the hydrophobic surface have been considered, and surfactants are generally used. However, surfactants other than component (b) of the present invention are less effective at improving wettability. Although the mechanism of action is unclear, it is presumed that in the present invention, components (a) and (b) form mixed micelles, which allows a small amount of cationic surfactant to be uniformly adsorbed on the hydrophobic surface.

In addition, from the viewpoint of discomfort such as sliminess and skin irritation, it is preferable to contact the deodorant composition of the present invention in a proportion of preferably 20 mg or more, more preferably 30 mg or more, even more preferably 40 mg or more, and preferably 400 mg or less, more preferably 200 mg or less, and even more preferably 100 mg or less relative to the hydrophobic surface of the object. 2It is preferable to contact the sample with the soluble polymer so that the amount of the soluble polymer is 20 μg or more, preferably 40 μg or more, more preferably 60 μg or more, even more preferably 80 μg or more, particularly preferably 100 μg or more, and 20 mg or less, preferably 10 mg or less, more preferably 5 mg or less.
