[0014] Examples of the (A) component include linear or branched aliphatic alcohols having 8 to 14 carbon atoms, and saturated or unsaturated aliphatic alcohols having 8 to 14 carbon atoms. The (A) component may be linear or branched, with linear alcohols being preferred from the viewpoint of deodorizing effect. The (A) component may be saturated or unsaturated aliphatic alcohol, with saturated aliphatic alcohols being preferred from the viewpoint of deodorizing effect. The (A) component is not particularly limited in the number of hydroxyl groups contained in the (A) component, but one is preferred from the viewpoint of deodorizing effect. The (A) component may be any of primary, secondary, and tertiary alcohols, with primary being preferred from the viewpoint of deodorizing effect.

The counter anion may be a methyl sulfate ester ion, an ethyl sulfate ester ion, or a halide ion, and a halide ion such as a chloride ion is preferable.

[0022] Examples of the (B-2) component include antibacterial compounds having a diphenyl ether skeleton, antibacterial compounds selected from phenol derivatives, and antibacterial compounds selected from benzoic acid derivatives. From the viewpoint of antibacterial properties and ease of fixation to textile products after washing (antibacterial maintenance), antibacterial compounds having a diphenyl ether skeleton, for example, antibacterial compounds containing halogen atoms and having a diphenyl ether skeleton, are preferred. Specific compounds include diclosan, triclosan, benzoic acid, paraben, etc., and from the viewpoint of antibacterial properties and ease of fixation to textile products after washing, diclosan and triclosan are preferred, and further from the viewpoint of ease of product design, diclosan is more preferred.

[0023] The content of component (B) in the composition is preferably 0.01% by mass or more, more preferably 0.05% by mass or more, even more preferably 0.1% by mass or more, and particularly preferably 0.15% by mass or more, from the viewpoint of the liquidity of the composition, and is preferably 4% by mass or less, preferably 3% by mass or less, more preferably 1.5% by mass or less, and particularly preferably 1% by mass or less. The content of component (B) is the amount based on the compound in which the counter anion is replaced with a chloride ion.

[0024] The content of the (B-1) component in the composition is preferably 0.05% by mass or more, more preferably 0.1% by mass or more, and even more preferably 0.3% by mass or more from the viewpoint of deodorizing performance, and is preferably 4% by mass or less, more preferably 2% by mass or less, and even more preferably 1% by mass or less from the viewpoint of the liquidity of the composition.

[0025] The content of the (B-2) component in the composition is preferably 0.01% by mass or more, and more preferably 0.03% by mass or more, from the viewpoint of deodorizing performance, and is preferably 1% by mass or less, and more preferably 0.5% by mass or less, from the viewpoint of the liquidity of the composition.

[0026] In the deodorant composition of the present invention, the mass ratio (B) / (A) of the content of the component (A) to the content of the component (B) is, from the viewpoint of deodorizing and disinfecting effect, preferably 0.005 or more, more preferably 0.05 or more, even more preferably 1 or more, and is preferably 50 or less, more preferably 30 or less, even more preferably 20 or less, even more preferably 10 or less, and even more preferably 6 or less.

[0028] Component (B) is known as an effective germicide that prevents the generation of bad odors caused by bacteria on fabrics such as clothing, and is frequently used in textile product treatments such as detergents and fabric softeners. However, on the other hand, the expected effect may not be obtained on objects on which dirt is present. This is presumably because the presence of dirt prevents component (B) from effectively contacting bacteria present on the fabric. Component (A) of the present invention, when used in combination with component (B), is thought to have the effect of forming an association with all or a part of component (B) and delivering component (B) to the inside of the dirt or to the surface of the fiber. For this reason, it is believed that the generation of odors caused by bacteria can be suppressed even in the presence of dirt.

The vesicle-forming surfactant in the present invention is a surfactant that forms vesicles in the actual use, and is affected by the concentration of the surfactant and the hardness of the water used. The actual use means that, for example, vesicles are formed when present in the washing water or rinsing water when washing clothes, and for example, vesicles may be formed at a concentration of 10 ppm to 200,000 ppm of component (C) in water with a German hardness of 1° DH to 20° DH. The vesicles can be confirmed by observing a Maltese cross when observed with a polarizing microscope.

Examples of the counter anion include halide ions such as bromide ion, iodide ion, and chloride ion, methyl sulfate ester ion, hydroxide ion, and acetate ion, and chloride ion is preferred.

[0041] Examples of the (C-3) component include dialkyl sulfosuccinates having 8 to 14 carbon atoms, specifically, dioctyl sulfosuccinate, didecyl sulfosuccinate, di-2-ethylhexyl sulfosuccinate, di-2-propylheptyl sulfosuccinate, and internal olefin sulfonates having 16 to 24 carbon atoms, with di-2-ethylhexyl sulfosuccinate being preferred from the viewpoint of ease of product design. Examples of the counter anion include sodium ion and potassium ion, with sodium ion being preferred.

[0042] In the deodorant composition of the present invention, the content of component (C) in the composition is preferably 3% by mass or more, more preferably 5% by mass or more, from the viewpoint of softening effect and antibacterial effect, and is preferably 20% by mass or less, more preferably 18% by mass or less, from the viewpoint of liquidity of the composition.

[0043] The component (C), which is a surfactant capable of forming vesicles and is listed in the above components (C-1) to (C-3), associates in a solution to form a bilayer membrane in which two molecules are arranged facing each other in the thickness direction of the membrane, and is stabilized. Furthermore, this bilayer membrane surrounds the cavity to form a spherical body (vesicle). When the component (C) coexists, a part or all of the component (B) of the present invention is taken up into the spherical body (vesicle) formed by the bilayer membrane of the component (C) and adsorbed to the target object such as a textile product. Therefore, the part where the vesicle of the component (C) is adsorbed can obtain a sufficient bactericidal and deodorizing effect, but the component (B) cannot be adsorbed to the part where the vesicle of the component (C) cannot be adsorbed or penetrated, and the expected effect cannot be obtained.

[0044] Furthermore, the present inventors have found that in the present invention, component (A) is supplied to sites where component (C) is not adsorbed (for example, inside a textile product) and exhibits the expected effect, unlike the behavior described in Patent Document 7. This is thought to be because the ratio of component (A) incorporated into component (C) in the composition is different from the ratio of higher alcohol incorporated into the inside of the vesicle in Patent Document 7 due to a blending method different from that in Patent Document 7, but the details are unknown.

[0045] More specifically, examples of the (B) component, particularly the (B-1) component, which is partially or completely incorporated into the spherical body (vesicle) formed by the bilayer membrane of the (C) component include antibacterial compounds represented by the following general formula (2).

Then, the mixture was dried for 12 hours under conditions of 25°C and 40% RH.

[0108] (3) The following evaluation treated fabrics 1 to 3 were prepared. Evaluation treated cloth 1: One of the evaluation cloths 1 treated in (2) above Evaluation treated cloth 2: Only the second cloth was taken out from the three evaluation cloths (evaluation cloth group 2) that had been treated in (2) above and bundled together. Evaluation treated cloth 3: Another one of the evaluation cloths 1 treated in (2) above was further subjected to the following model staining treatment.

[0109] <Model contamination treatment> 50 mL of methanol and 500 mg of triolein as a model sebum stain were added to a 100 mL beaker, and ultrasonic treatment was performed to prepare a triolein dispersion. The dispersion was applied to one piece of evaluation cloth treated in (2) above so that 10 mg of triolein was applied, and the cloth was left to stand overnight.

[0110] [Evaluation of deodorizing performance] 100 μg of 14-methylhexadecanoic acid dissolved in methanol was applied to each of the treated cloths 1 to 3 for evaluation in (3) above. After drying, 800 μL of the following bacterial solution was inoculated onto each treated cloth, which was then placed in an airtight container and allowed to stand at 37° C. for 18 hours.

[0111] <Preparation of bacterial solution> Based on JIS L1902, Moraxella sp. (KMC-41 strain, clothing-isolated bacteria) was applied to an SCDLP agar medium (manufactured by Nippon Pharmaceutical Co., Ltd.) and cultured at 37°C for 24 hours. The cultured bacteria was suspended in NTB liquid medium (Becton, Dickinson and Company) diluted 20-fold with physiological saline, and 1.0 × 10 5 The bacterial concentration was adjusted to cfu / mL.

[0112] Evaluation criteria: Ten panelists performed a sensory evaluation on each piece of dried cloth according to the following evaluation criteria.

[0113] Almost no smell...0 points There is a slight smell, but it doesn't bother me... 1 point Smells...2 points Noticeable odor...3 points

[0114] From the results of Examples 1 to 9, it was confirmed that the deodorant composition of the present invention provides a good deodorizing effect on the inside of the textile product (deodorizing performance 1, 2). In particular, it was confirmed that Example 5, which contains 1.0 mass % of the (A) component, provides a better deodorizing effect on the inside of the textile product. This is presumed to be because in the deodorant composition of the present invention, the (A) component is not unevenly distributed on the surface of the textile product but is distributed throughout the interior of the textile product, thereby providing a deodorizing effect even inside the textile product. It is also presumed that the use of the (B) component in the deodorant composition of the present invention provides antibacterial properties on the surface and interior of the textile product.

[0115] Furthermore, from the results of Examples 1 to 9, it was confirmed that the deodorant composition of the present invention has a deodorant effect even on textile products on which dirt coexists (deodorant performance 3). Cationic antibacterial compounds are easily adsorbed to dirt on textile products, and there is concern that the antibacterial properties will decrease if dirt coexists. The deodorant composition of the present invention containing component (A) provides the required deodorant effect even in the presence of dirt.
