Description

[Technical Field]

[0001] The present invention relates to a deodorizing composition and a spray-type deodorizing product. [Background technology]

[0002] In recent years, with the rise in consumer awareness of hygiene, there has been growing interest in eliminating unpleasant odors in the living environment. When used towels and dishcloths in the kitchen are left as they are, they can emit a damp odor caused by dirt and bacteria, which has become a problem.

[0003] The damp smell is also a problem when drying laundry after washing, and tends to occur especially when washing clothes that are highly soiled or smelly, when laundry is left in the washing machine for a long time, or when laundry is hung to dry indoors and not dried sufficiently.

[0004] To combat this damp odor, damp odor inhibitors have been reported that can suppress the generation of damp odor by inhibiting the production of 4-methyl-3-hexanoic acid by microorganisms capable of producing 4-methyl-3-hexanoic acid (see Patent Documents 1 to 3).

[0005] However, the damp odor inhibitors of Patent Documents 1 to 3 are primarily focused on suppressing the generation of damp odor, and there is still room for further study regarding the deodorizing effect on damp odor that has already occurred. [Prior art documents] [Patent documents]

(4) The deodorizing composition according to any one of (1) to (3), wherein the plant extract is one or more selected from the group consisting of ginkgo extract, fig extract, and forsythia extract. (5) The deodorizing composition according to any one of (1) to (4), which has a pH of 2.0 to 7.0 at 20°C. (6) The deodorizing composition according to any one of (1) to (5), which is used to deodorize damp clothes. (7) A spray-type deodorizing product comprising the deodorizing composition according to any one of (1) to (6) contained in a spray container. [Effects of the Invention]

[0010] The deodorizing composition and spray-type deodorizing product of the present invention exhibit excellent deodorizing effects. DETAILED DESCRIPTION OF THE INVENTION

[0011] The deodorizing composition and spray-type deodorizing product of the present invention will be described below. However, the present invention is not intended to be limited to the configurations described below. In this specification, the unit of content "w / v%" is synonymous with "g / 100 ml." In addition, when a range is indicated by "to" in this specification, it is assumed that the range includes both the upper and lower limits.

[0012] The deodorizing composition of the present invention contains (A) a hydroxycarboxylic acid and / or a plant extract and (B) a lower alcohol having 2 to 3 carbon atoms, and exhibits excellent deodorizing effects, particularly a remarkable deodorizing effect on damp odors.

[0013] [(A) Hydroxycarboxylic acid and / or plant extract] Component (A) is a hydroxycarboxylic acid and / or a plant extract. Hydroxycarboxylic acids are carboxylic acids with at least one hydroxyl group in the molecule, and they exert a chemical deodorizing effect against malodors. Plant extracts are solutions and dried products extracted from plants using aqueous solvents such as water, ethanol, 1,3-butylene glycol, or a mixture of these solvents, or oils and fats as the solvent. The plant-derived components have the effect of non-volatilizing, neutralizing, and decomposing malodors, while the plant-derived aromatic components have the effect of masking malodors. It is believed that the deodorizing effect is the synergistic effect of both.

[0014] The hydroxycarboxylic acid is not particularly limited, but examples thereof include glycolic acid, lactic acid, hydroxyacrylic acid, glyceric acid, malic acid, tartaric acid, citric acid, etc., and one or more selected from the group consisting of lactic acid, malic acid, tartaric acid, and citric acid are preferred, lactic acid and / or citric acid are more preferred, and lactic acid is particularly preferred. The hydroxycarboxylic acids may be used alone or in combination of two or more.

[0015] Examples of plant extracts include, but are not limited to, sugarcane, persimmon, ginkgo, fig, forsythia, tea, bamboo, wood sorrel, Houttuynia cordata, hemlock, black pine, larch, red pine, paulownia, holly, osmanthus, lilac, sweet osmanthus, butterbur, Japanese silverleaf, chestnut, alder, oak, pomegranate, fern, Japanese laurel, persimmon, plantain, mugwort, Japanese maple, crape myrtle, Japanese bush clover, Japanese andromeda, fern, aspen, and Fraxinus repens. Among these, sugarcane extract, persimmon extract, ginkgo extract, fig extract, and forsythia extract are preferred, and one or more selected from the group consisting of ginkgo extract, fig extract, and forsythia extract are particularly preferred. The plant extracts may be used alone or in combination of two or more.

[0016] In the deodorizing composition of the present invention, the amount of (A) hydroxycarboxylic acid and / or plant extract to be blended is not particularly limited, but from the viewpoint of exhibiting an excellent deodorizing effect, it is preferably blended in at 0.1 w / v% or more, more preferably 0.1 to 3.0 w / v%, and even more preferably 0.5 to 3.0 w / v%.

[0017] [(B) Lower alcohol having 2 to 3 carbon atoms] In the present invention, examples of the (B) lower alcohol having 2 to 3 carbon atoms include ethanol, isopropanol, and normal propanol, with ethanol and / or isopropanol being preferred, and isopropanol being more preferred. In the present invention, by incorporating the (B) lower alcohol having 2 to 3 carbon atoms, the deodorizing effect of the (A) hydroxycarboxylic acid and / or plant extract is enhanced, resulting in an excellent deodorizing effect, and in particular a remarkable deodorizing effect against damp odors.

[0018] The amount of (B) lower alcohol having 2 to 3 carbon atoms in the present invention is not particularly limited, but is preferably 10 to 80 w / v%, more preferably 20 to 70 w / v%, and particularly preferably 25 to 50 w / v%.

[0019] [(C)Fragrance] Although the fragrance (C) is not an essential component of the deodorant composition of the present invention, it is preferable to incorporate it. Examples of such (C) fragrances include, but are not limited to, linalool, terpineol, allyl hexanoate, allyl heptanoate, thymol, l-menthol, menthyl acetate, menthone, p-menthane-3,8-diol, 1,8-cineole, d-limonene, phenethyl alcohol, geraniol, benzyl acetate, bornole, cinnamaldehyde, citronellol, citronellal, camphor, α-pinene, lavandulol, amyl cinnamic aldehyde, cumin aldehyde, green leaf alcohol, and green leaf aldehyde; as well as citronella oil, lemongrass oil, lemon oil, lime oil, orange oil, peppermint oil, lavender oil, clove oil, bergamot oil, peppermint oil, cypress oil, eucalyptus oil, lemon-eucalyptus oil, lime oil, yuzu oil, jasmine oil, and green tea essential oil. These may be blended as a single component or as a mixture. Among them, it is preferable to contain one or more selected from the group consisting of linalool, terpineol, allyl hexanoate, allyl heptanoate, thymol, l-menthol, menthyl acetate, menthone, p-menthane-3,8-diol, 1,8-cineole, d-limonene, phenethyl alcohol, geraniol, benzyl acetate, and borneool, because they have an excellent effect of suppressing the generation of damp odor. That is, by containing one or more selected from the group consisting of linalool, terpineol, allyl hexanoate, allyl heptanoate, thymol, l-menthol, menthyl acetate, menthone, p-menthane-3,8-diol, 1,8-cineole, d-limonene, phenethyl alcohol, geraniol, benzyl acetate, and borneool, the deodorizing composition of the present invention exhibits an excellent deodorizing effect as well as an excellent effect of preventing the generation of damp odor.

[0020] The blending amount of the (C) fragrance in the present invention is not particularly limited, but is preferably 0.01 to 5.0 w / v%, more preferably 0.1 to 4.0 w / v%, and particularly preferably 0.6 to 3.0 w / v%.

[0021] The deodorizing composition of the present invention can be blended with water, and examples of water include purified water such as ion-exchanged water and reverse osmosis water, ordinary tap water, industrial water, and deep sea water.

[0022] [pH of deodorant composition] The pH of the deodorizing composition of the present invention is not particularly limited, but is preferably 2.0 to 7.0, and more preferably 2.5 to 7.0, at 20°C. By adjusting the pH within this range, an excellent deodorizing effect, particularly a remarkable deodorizing effect against damp odors, can be exhibited. The pH can be adjusted by the content of the blended (A) component, or by using a separate pH adjuster.

[0023] In addition to the above components, the deodorizing composition of the present invention may also contain appropriate additives such as insecticides, repellents, deodorizing agents other than component (A), other organic solvents, surfactants, stabilizers, antistatic agents, thickeners, antifungal agents, preservatives, pigments, antioxidants, gelling agents, ultraviolet absorbers, and defoaming agents, as long as they do not deviate from the gist of the present invention. Examples of insecticidal components include pyrethroid compounds such as transfluthrin, metofluthrin, profluthrin, telallethrin, furamethrin, empenthrin, momfluorothrin, dimefluthrin, mepafluthrin, heptafluthrin, fenothrin, cyphenothrin, permethrin, cypermethrin, cyfluthrin, bifenthrin, fenpropathrin, tralomethrin, etofenprox, imiprothrin, allethrin, phthalthrin, prallethrin, resmethrin, and natural pyrethrins; silicon compounds such as silafluofen; organophosphorus compounds such as dichlorvos and fenitrothion; carbamate compounds such as propoxur; neonicotinoid compounds such as dinotefuran, imidacloprid, and clothianidin; fipronil, indoxacarb, brofuranilide, and methoxadiazone. Examples of repellents include DEET, ethyl butylacetylaminopropionate (IR3535), and icaridin. Other organic solvents include ester-based solvents such as ethyl acetate and isopropyl myristate, ketone-based solvents such as acetone, hydrocarbon-based solvents such as hexane, normal paraffin, and isoparaffin, glycol-based solvents and glycol ether-based solvents such as ethylene glycol, propylene glycol, and 1,3-butylene glycol. In addition, when optical isomers based on asymmetric carbons or geometric isomers based on double bonds of each component exist, these may be used individually or in any mixture.

[0024] The deodorant composition of the present invention can be prepared in a liquid form and can be used by being stored in a spray container as is, or by adding a propellant such as liquefied gas or compressed gas and filling it into an aerosol container. Among these, it is preferable to store it in a spray container for use. Note that known spray containers can be used.

[0025] The amount of the spray to be dispensed when used as a spray is not particularly limited, but is preferably 0.1 to 2.0 mL per push, and more preferably 0.2 to 1.5 mL.

[0026] The deodorizing composition and spray-type deodorizing product of the present invention can be suitably used for deodorizing purposes, and can be particularly suitably used for deodorizing damp odors. Specifically, by treating textile products such as used towels and dishcloths that already have a damp odor, the damp odor can be deodorized. Furthermore, by treating textile products such as towels and dishcloths immediately after washing, the generation of a damp odor in the textile product can be prevented, and even damp odors that have already occurred can be deodorized. Furthermore, since the composition and spray-type deodorizing product can exhibit excellent deodorizing effects against base-based odors such as trimethylamine and ammonia, and against odors such as methyl mercaptan, they can be widely used as household deodorizing products and commercial deodorizing products. [Example]

[0027] The present invention will be explained in more detail below with reference to examples, but the present invention is not limited to these examples in any way.

[0028] The ingredients used will be explained below. Component (A) Lactic acid (Fujifilm Wako Pure Chemical Industries, Ltd.) Citric acid (Fujifilm Wako Pure Chemical Industries, Ltd.) Acetic acid (manufactured by Fujifilm Wako Pure Chemical Industries, Ltd.) Plant extract 1 (mixture of ginkgo extract, fig extract, and forsythia extract, product name: Super Puriere, manufactured by Panasonic Chemical Co., Ltd.) (B) Lower alcohols with 2 to 3 carbon atoms Ethanol (product name: Ethanol (99.5), manufactured by Fujifilm Wako Pure Chemical Industries, Ltd.) Isopropanol (trade name: 2-propanol, manufactured by Fujifilm Wako Pure Chemical Industries, Ltd.) (C)Fragrance Fragrance 1 (a compound fragrance containing linalool, allyl ester, and terpineol)

[0029] Deodorizing compositions were prepared according to the formulations shown in Tables 1 and 2, and filled into spray containers to obtain spray-type deodorizing products (amount discharged per time: approximately 0.7 mL). The obtained spray-type deodorizing products were subjected to the following deodorizing test to confirm their deodorizing effects.

[0030] <Deodorizing effect on damp towels (used towels)> A used towel that had already started to smell damp was cut into two pieces measuring 30 cm x 30 cm. Each towel was soaked in water once and wrung out. Four pumps of the spray-type deodorizing product of Example 1 were applied to one of the towels from a distance of 20 cm, and the towel was left for five minutes, then placed in a plastic bag with a zipper and sealed. The other towel was left untreated and placed in a plastic bag with a zipper and sealed, serving as an untreated group. For evaluation, the untreated group was assigned an E rating, and the deodorizing effect was evaluated according to the following criteria. The evaluation was determined by discussion among five panelists. Similar tests were also conducted on Examples 2 to 9, Comparative Examples 1 and 2, and Reference Example 1 (the test results are shown in Tables 1 and 2). (Evaluation criteria) A: No damp smell at all B: Almost no smell of dampness C: The smell of dampness is weak D: A damp smell is normally felt E: There is a strong smell of dampness

[0031] <Deodorizing effect on damp towels (after washing)> Used towels that already had a strong damp odor were cut into two pieces measuring 30 cm x 30 cm. Each towel was washed in a washing machine using commercially available laundry detergent under the following conditions: 12 minutes of washing, one rinse, and 8 minutes of spin-drying. Even at this stage, the towels still retained a damp odor. One of the towels was sprayed with one pump of the spray-type deodorizing product of Example 1 from a distance of 30 cm, sealed in a plastic bag with a zipper, and left in a 40°C thermostatic chamber (average humidity 75%) for 24 hours. The other towel was left untreated after washing, sealed in a plastic bag with a zipper, and left in a 40°C thermostatic chamber (average humidity 75%) for 24 hours. This served as the untreated group. The untreated group was assigned an E rating, and the deodorizing effect was evaluated according to the following criteria. The evaluation was determined by discussion among five panelists. Similar tests were also conducted on Examples 2 to 9, Comparative Examples 1 and 2, and Reference Example 1 (the test results are shown in Tables 1 and 2). (Evaluation criteria) A: No damp smell at all B: Almost no smell of dampness C: The smell of dampness is weak D: A damp smell is normally felt E: There is a strong smell of dampness

[0032] <Effect of generating damp smell> [1] A new towel was cut into two pieces measuring 30cm x 30cm. [2] Each towel was dipped in water once, wrung out, wiped once on a desk measuring 100 cm x 150 cm, and then dipped in water again and wrung out. Four pumps of the spray-type deodorizing product of Example 1 were applied to one towel from a distance of 20 cm, and the towel was allowed to dry indoors. The other towel was left untreated and allowed to dry indoors, serving as the untreated group. [3] The above procedure [2] was repeated twice a day. [4] The same procedure was repeated for 29 days from the start of the test, and five panelists were asked to smell the towels treated in Example 1 and the untreated towels, and the effectiveness in preventing damp odor was evaluated according to the following criteria. The evaluation was determined by discussion among the five panelists. [5] Furthermore, the same tests were carried out on Examples 2 to 9, Comparative Examples 1 and 2, and Reference Example 1 (the test results are shown in Tables 1 and 2).

[0033] [Table 1]

[0034] [Table 2]

[0035] The test results confirmed that the deodorizing compositions of Examples 1 to 9, which contain (A) a hydroxycarboxylic acid and / or a plant extract and (B) a lower alcohol having 2 to 3 carbon atoms, exhibit excellent deodorizing effects. Among these, the deodorizing compositions of Examples 2, 4, 6, and 9, which contain isopropanol as component (B), exhibited excellent deodorizing effects for damp odors of grades A or higher on both used towels and washed towels, demonstrating even more excellent deodorizing effects. Furthermore, the deodorizing compositions of Examples 1 to 6, 8, and 9 and Reference Example 1, which contain a blended fragrance containing linalool, allyl ester, and terpineol as fragrance (C), were also found to be effective in preventing the generation of damp odors.

[0036] On the other hand, the deodorizing composition of Comparative Example 1, which did not contain (A) hydroxycarboxylic acid and / or plant extract, and the deodorizing composition of Comparative Example 2, which contained other organic acids, had insufficient deodorizing effects.
