Summary of the Invention

Problems to be Solved by the Invention

[0005] In the field of detergents for textile products, sodium dodecylbenzenesulfonate (LAS) is widely used. By using a cationic surfactant having a bactericidal effect in combination with LAS, it seems that both a bactericidal effect and a cleaning effect can be achieved. However, in reality, the bactericidal effect is attenuated. This is considered to be due to the formation of a complex between the cationic surfactant and LAS, resulting in precipitation and crystallization.

[0006] Accordingly, the present invention relates to providing a disinfectant that exhibits a suitable bactericidal effect despite containing both cationic and anionic surfactants. Furthermore, the present invention relates to providing a detergent composition that exhibits a bactericidal effect while maintaining cleaning power, further containing a nonionic surfactant in addition to cationic and anionic surfactants.

Advantages of the Invention

[0010] According to the present invention, it is possible to provide a bactericide having a suitable bactericidal effect despite containing both a cationic surfactant and an anionic surfactant. Further, according to the present invention, in addition to the cationic surfactant and the anionic surfactant, it is possible to provide a detergent composition containing a nonionic surfactant and having a bactericidal effect while maintaining detergency.

Modes for Carrying Out the Invention

[0011] As a result of our investigations, we selected a quaternary ammonium salt having a specific alkyl group from among various cationic surfactants, specifically a dialkyl quaternary ammonium salt having two C8 alkyl groups, and found that by combining this with an anionic surfactant having a specific structure, the bactericidal effect of the cationic surfactant was not reduced, thus completing the present invention. The mechanism by which such effects are exerted is not necessarily limited, but is thought to be as follows. It is known that when cationic surfactants and anionic surfactants coexist in water, they form a complex. If the crystallinity of the complex becomes too high, even if the complex adheres to the surface of bacteria, the cationic surfactant, which is the bactericidal component, may detach from the complex on the bacteria and have difficulty penetrating into the inside of the bacteria. The combination of a cationic surfactant having a specific structure and an anionic surfactant having a specific structure in the present invention is presumed to exhibit excellent bactericidal activity against bacteria because, even if a complex is formed in water, the crystallinity of the complex does not become high, and when the complex adheres to the surface of bacteria, the cationic surfactant can easily detach from the complex and penetrate into the inside of the bacteria.

[Examples]

[0101] The present invention will be specifically described below with reference to examples. Note that the following examples are merely illustrative of the present invention and do not imply any limitation.

[0102] <Composition ingredients> The following ingredients were used in the examples, comparative examples, and formulation examples. Note that the amounts of each ingredient in the table are the amounts of the active ingredients, not the amounts of the product.

[0103] [(b) component] (b-1): Dioctylethylmethylammonium ethyl sulfate (85% by mass ethanol solution)

[0104] [(c) component] (c-1): In the above general formula (c1-1), R 8 (A) is a lauryl group, m is 0, (AO) is an ethylene oxy group, n is 10, R 9 is a compound of H (c-2): In the above general formula (c1-1), R 8 is a mixed alkyl group (lauryl group / myristyl group = 7 / 3 (mass ratio)), m is 0, (AO)n is a group obtained by adding 4 moles of propylene oxy to an alcohol with a mixed alkyl group as the hydrocarbon group, and then adding 17 moles of ethylene oxy group (n=21), R 9 is a compound of H (c-3): In the above general formula (c1-1), R 8 (A) is a lauryl group, m is 0, (AO) is an ethylene oxy group, n is 7, R 9 is a compound of H

[0105] [(d) component] (d-1): In the above general formula (2), R5 (A) is a dodecyl group, and (AO)n is a compound obtained by adding a propylene oxide group to dodecyl alcohol at a ratio of 0.6 moles per mole, then esterifying with sulfuric acid, and neutralizing with sodium hydroxide (n=0.6). + Compounds in which sodium ions are present. (d-2): Potassium C16 internal olefin sulfonate obtained by the following manufacturing method

[0106] • Production of C16 internal olefin a1 Internal olefin a1 with 16 carbon atoms, which is the raw material for component (d-2), was produced according to the method described below. The internal olefin with 16 carbon atoms was produced in accordance with production example C of Japanese Patent Application Publication No. 2014-76988. The double bond distribution of the internal olefin is as follows. In internal olefin a1, the mass percentage of internal olefins with double bonds at the following positions was 1st / 2nd / 3rd / 4th / 5th / 6th / 7th / 8th = 2.3% / 23.6% / 18.9% / 17.5% / 13.7% / 11.2% / 6.4% / 6.4% (total 100 mass%).

[0107] The double bond distribution of the internal olefin a1 was measured by gas chromatography (hereinafter abbreviated as GC). Specifically, the internal olefin was reacted with dimethyl disulfide to form a dithiolated derivative, and then each component was separated by GC. As a result, the proportion of the double bond distribution of the internal olefin was determined from the peak area of ​​each component, and this proportion was taken as the mass proportion. Note that in olefins with 16 carbon atoms, internal olefins with a double bond at position 7 and internal olefins with a double bond at position 8 are structurally indistinguishable, but they become distinguishable when sulfonated. For convenience, the amount of internal olefin with a double bond at position 7 was divided by 2 and shown in each column. The apparatus and analytical conditions used for the measurement are as follows. GC system "HP6890" (manufactured by Hewlett Packard), column "Ultra-Alloy-1HT capillary column" (30m x 250μm x 0.15μm, manufactured by Frontier Labs Co., Ltd.), detector (flame ion detector (FID)), injection temperature 300℃, detector temperature 350℃, He flow rate 4.6mL / min

[0108] Manufacturing of (d-2) The aforementioned internal olefin a1 was subjected to a sulfonation reaction using a thin-film sulfonation reactor with an external jacket, by passing sulfur trioxide gas and cooling water at 20°C through the reactor's external jacket. The molar ratio of SO3 to internal olefin during the sulfonation reaction was set to 1.09. The obtained sulfonate was added to an alkaline aqueous solution prepared with 1.5 molar times the theoretical acid value of potassium hydroxide, and neutralized at 30°C for 1 hour with stirring. The neutralized product was hydrolyzed by heating in an autoclave at 160°C for 1 hour to obtain a crude potassium sulfonate product of the C16 internal olefin. 300 g of the crude product was transferred to a separatory funnel, 300 mL of ethanol was added, and then 300 mL of petroleum ether was added in each step to extract and remove oil-soluble impurities. At this time, inorganic compounds (mainly potassium sulfate) precipitated at the oil-water interface due to the addition of ethanol were also separated and removed from the aqueous phase by oil-water separation. This extraction and removal operation was performed three times. Potassium olefin sulfonate was obtained by evaporating the aqueous phase to dryness.

[0111] Examples 1-14, Comparative Examples 1-3, and Reference Example 1 <Preparation of disinfectants> Using the above-mentioned ingredients, the fungicides shown in Tables 1 to 3 were prepared by the following method. 90% of the amount of water needed to produce a final mass of 300g was placed in a 500ml glass beaker and heated to 40°C in a water bath. A 6cm diameter Teflon® rod-shaped stirrer bead was placed inside and rotated at 60 r / m with a magnetic stirrer. Any component (c) was added and stirred for 5 minutes. Then component (d) or (d') was added, followed by component (b) heated to 40°C, and stirred for another 15 minutes. Then, water was added to produce a final mass of 300g, and stirred for another 5 minutes.

[0112] Test Example 1 <Evaluation of bactericidal activity> The bactericidal activity of each bactericide prepared using the above-mentioned ingredients was evaluated as follows. (1) Moraxella sp. bacteria isolated from worn clothing were streaked onto plates of SCD-LP agar (manufactured by Shioya MS Co., Ltd.) and cultured at 37°C for approximately 24 hours. The cultured samples were then scraped off with a platinum loop and diluted with sterile water to prepare a bacterial concentration of OD600 = 1.0. (2) 0.1 mL of the bacterial solution from (1) was added to 9.9 mL of the test solution (the liquid detergent composition shown in the table, diluted with water to a concentration of 1 g / L when in contact with the bacterial cells) and mixed, and the mixture was allowed to come into contact at 20°C for 10 minutes. Sterilized tap water was used for all water. (3) The test solution to which the bacteria were in contact in (2) was serially diluted with LP diluent (manufactured by Shioya MS Co., Ltd.), and the number of colonies grown on SCD agar medium (manufactured by Shioya MS Co., Ltd.) was counted by the pour plate method. The bactericidal activity value was calculated using the following formula. In this evaluation, a higher bactericidal activity value indicates a better bactericidal effect. Bactericidal activity value = LogA - LogB A: Average number of bacteria before contact with the test solution B: Average value of bacterial count after contact with test solution

Therefore, the compositions of Examples 1-3 have sufficient bactericidal activity as disinfectants. Furthermore, a comparison between Examples 4-14 and Comparative Examples 2-3 confirmed similar results for compositions containing the nonionic surfactant component (c). Specifically, it was found that compositions using LAS, an anionic surfactant that does not fall under component (d) (Comparative Examples 2-3), had inferior bactericidal activity compared to compositions containing component (d) (Examples 4-14). It was found that the compositions of Examples 4-14, even with the inclusion of nonionic surfactants, possessed sufficient bactericidal activity as disinfectants.

[0118] Examples 15-30 <Preparation of detergent composition> 90% of the amount of water needed to produce a final mass of 300g was placed in a 500ml glass beaker and heated to 40°C in a water bath.

[0122] (3) Washing test The washing operation was performed using a turgotometer (manufactured by Ueshima Seisakusho). The water used for washing was water obtained by adding calcium chloride and magnesium chloride in a mass ratio of 8:2 to ion-exchanged water and adjusting the hardness to 4°dH. The washing solution was obtained by mixing the textile product detergent composition with the washing water so that the mass ratio of textile product detergent composition / washing water, as described in Table 3, was 30g / 30L. 0.6L of the washing solution and 10 of the aforementioned model sebum-stained artificial cloths were placed in a 1-liter stainless steel beaker for the washing test. The bath ratio was adjusted to 20 using the aforementioned textile product for purification evaluation. The temperature of the washing solution was 20°C. The evaluation fibers were washed with a turgotometer at 85 rpm for 10 minutes. After washing, the fibers were dewatered, and all the dewatered fibers were placed in 0.6L of washing water and rinsed with a turgotometer at 85 rpm for 3 minutes.
