Description

[Technical Field]

[0001] The present invention relates to a deodorizing composition for solvent odors and a method for deodorizing solvent odors using the same. [Background technology]

[0002] Various unpleasant odors are generated during the manufacturing process at chemical plants, paper mills, etc. These odors are usually low in concentration, but odor control measures are necessary, especially if there are residential areas nearby. For this reason, in these factories, odorous gases are sucked in and introduced into deodorizing equipment, where they are subjected to stripping, activated carbon treatment, biological treatment, chemical cleaning treatment, etc., and then discharged outside the system as odorless exhaust gas (see Patent Documents 1 and 2). Furthermore, various unpleasant odors are generated even in the home. To combat such odors, aromatic deodorizers (masking agents, odor neutralizers, etc.) that mainly contain fragrances are sprinkled or sprayed (see Patent Document 3).

[0003] However, the method of treating the odorous gas by sucking it into the deodorizing device requires high installation costs for the sucking and deodorizing device, and may not be easily implemented. In particular, chemical plants and the like frequently use solvents such as xylene, toluene, and benzene, and these organic solvents are the cause of solvent odors. Tar also produces solvent odors. Generally, the concentration of these solvent odors is low in many cases, and introducing a relatively large-scale device like the one described above to treat solvent odors not only increases equipment costs, but also results in problems of poor treatment efficiency. On the other hand, in the home, although the above-mentioned aromatic deodorizers can eliminate most odors, there is a problem in that they are not effective in deodorizing and masking solvent odors that are emitted from stationery such as ballpoint pens that use solvents, and various household oil-based paints.

[0004] To address this problem, a deodorizer composition for solvent odors containing three or more specific fragrance components has been proposed (Patent Document 4). [Prior art documents] [Patent documents]

The solvent odor is preferably a coke odor.

[0009] The present invention also provides a method for deodorizing solvent odors, which comprises sprinkling, spraying or adding the above-mentioned deodorant composition for solvent odors. The present invention will be described in detail below. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a deodorizer composition that is effective against odors containing various components, such as organic solvent odors such as toluene and xylene, and odors that occur during coal combustion and coke odors. It is also possible to provide an easy and effective deodorizing method for odors containing various components, such as organic solvent odors such as toluene and xylene, and odors that occur during coal combustion and coke odors. Furthermore, the deodorizing treatment using the deodorizer composition for solvent odors of the present invention and the deodorizing method for solvent odors of the present invention do not produce any new unpleasant odors after treatment. DETAILED DESCRIPTION OF THE INVENTION

[0011] The solvent odors targeted by the solvent odor deodorant composition and deodorizing method of the present invention are organic solvent odors generated from organic solvents such as xylene, toluene, and benzene, and coke odors, which are odors containing multiple components. In this specification, solvent odors include the above organic solvent odors and coke odors, but when describing each odor specifically, they will be referred to as organic solvent odors and coke odors. The organic solvent odor is generated, for example, from solvent tanks used in chemical plants, etc. The coke odor is generated, for example, from coke ovens and tar decanters in steel plants.

[0012] The deodorant composition for solvent odors of the present invention contains, as at least an active ingredient, at least one of fragrance composition A containing at least one fragrance ingredient selected from the following group a and dihydrojasmone; fragrance composition B containing at least one fragrance ingredient selected from the following group b and γ-methylionone; fragrance composition C containing at least one fragrance ingredient selected from the following group c and isoamyl salicylate; and fragrance composition D containing at least one fragrance ingredient selected from the following group d and styrallyl acetate. Group a: γ-methyl ionone, isoamyl salicylate, styrallyl acetate, anisyl acetate, cis-3-hexenyl salicylate, methyl (Z)-3-hexenyl carbonate, and linalool Group b: dihydrojasmone, isoamyl salicylate, styrallyl acetate, anisyl acetate, methyl 2-octynoate and linalool Group c: dihydrojasmone, γ-methyl ionone, anisyl acetate, cis-3-hexenyl salicylate, methyl 2-octynoate, methyl (Z)-3-hexenyl carbonate, and linalool Group d: dihydrojasmone, γ-methylionone, cis-3-hexenyl salicylate, and methyl (Z)-3-hexenyl carbonate By containing as an active ingredient at least one of fragrance compositions A, B, C, and D, which contain two or more specific fragrance components, the deodorizing composition exhibits an effective deodorizing effect not only on solvent odors consisting of a single component, but also on solvent odors consisting of multiple components. The deodorant composition for solvent odors of the present invention may contain other fragrance components in addition to at least one of fragrance compositions A, B, C, and D, which contain the above-mentioned two or more specific fragrance components.

[0013] The solvent odor deodorant composition of the present invention only needs to contain, as at least an active ingredient, at least one of the fragrance compositions A, B, C, and D described above. For example, in addition to the fragrance composition A, B, C, or D described above, the deodorant composition may contain at least one fragrance component selected from the group consisting of dihydrojasmone, γ-methyl ionone, isoamyl salicylate, styrallyl acetate, anisyl acetate, cis-3-hexenyl salicylate, methyl 2-octynoate, methyl (Z)-3-hexenyl carbonate, and linalool, and may contain three or more fragrance components. The solvent odor deodorant composition of the present invention may also be a composition containing nine fragrance ingredients consisting of dihydrojasmone, γ-methylionone, isoamyl salicylate, styrallyl acetate, anisyl acetate, cis-3-hexenyl salicylate, methyl 2-octynoate, methyl (Z)-3-hexenyl carbonate, and linalool.

[0014] The deodorant composition for solvent odors of the present invention can be used in the form of a solution, either an aqueous system prepared by dissolving the selected fragrance in a suitable solvent such as water or alcohol, or a non-aqueous system prepared by using a concentrated surfactant or the like. The solvent contained in the solvent odor deodorant composition of the present invention is not particularly limited, and water, alcohol, etc. can be used. However, a solvent that is low in odor, low in toxicity, biodegradable, and highly safe is preferred. This is because solvent odor deodorant compositions containing such a solvent can be used safely for the environment and humans in chemical plants and steelworks. Examples of such solvents include 3-methoxy-3-methyl-1-butanol, propylene glycol, dipropylene glycol, butylene glycol, dipropylene glycol monomethyl ether, diethylene glycol monoethyl ether, triethyl citrate, and isopropyl myristate. The solvent contained in the solvent odor deodorant composition of the present invention preferably contains at least one solvent selected from the group consisting of 3-methoxy-3-methyl-1-butanol, propylene glycol, dipropylene glycol, butylene glycol, dipropylene glycol monomethyl ether, diethylene glycol monoethyl ether, triethyl citrate, and isopropyl myristate, and more preferably contains 3-methoxy-3-methyl-1-butanol.

[0015] In the case of the aqueous system, a surfactant may be added in addition to the fragrance component to facilitate dissolution, emulsification, dispersion, penetration, etc. of the fragrance, depending on the concentration of the fragrance. As the surfactant used in the deodorant composition for solvent odors of the present invention, any of nonionic, anionic, cationic and amphoteric surfactants can be used, but it is preferable to use a nonionic surfactant. Examples of such nonionic surfactants include fatty alcohol (8-24 carbon atoms) alkylene oxide (2-8 carbon atoms) adducts (degree of polymerization = 1-100), polyhydric (dihydric to decahydric or higher) alcohol fatty acid (8-24 carbon atoms) esters [glycerin monostearate, sorbitan monolaurate, polyoxyethylene glycol sorbitan monooleate, etc.], fatty acid (8-24 carbon atoms) alkanolamides [1:1 type coconut oil fatty acid diethanolamide, 1:1 type dilaurate], and the like. ethanolamides, etc.], (poly)oxyalkylene (carbon number 2 to 8, degree of polymerization = 1 to 100) alkyl (carbon number 1 to 22) phenyl ethers, polyoxyalkylene diols, (poly)oxyalkylene (carbon number 2 to 8, degree of polymerization = 1 to 100) alkyl (carbon number 8 to 24) amines and alkyl (carbon number 8 to 24) dialkyl (carbon number 1 to 6) amine oxides [lauryl dimethyl amine oxide, etc.], polyoxyethylene hydrogenated castor oil, and the like, but are not limited to these. Furthermore, in order to further facilitate dissolution, emulsification, dispersion and penetration of the fragrance in the deodorant composition for solvent odors, or to prevent the deodorant composition for solvent odors from solidifying, polyhydric alcohols may also be added. Examples of such polyhydric alcohols include propylene glycol, dipropylene glycol, polypropylene glycol, propylene glycol monoethyl ether, ethylene glycol, diethylene glycol, polyethylene glycol, ethylene glycol monoethyl ether, isoprene glycol, pentaerythritol, and sorbitol.

[0016] In the case of an aqueous composition, the concentrations of the components in the deodorant composition for solvent odors of the present invention are usually 0.1 to 10 mass% of fragrance, 0.5 to 20 mass% of surfactant if necessary, and 1 to 30 mass% of polyhydric alcohol if further necessary, with the remainder being water. On the other hand, in the case of a non-aqueous system, the fragrance is typically blended in an amount of 0.5 to 60% by mass, with the remainder being surfactants, or when polyhydric alcohols are added, the polyhydric alcohols are typically blended in an amount of 1 to 30% by mass, with the remainder being surfactants.

[0017] Such a solution-type deodorant composition for solvent odors can be directly sprinkled or sprayed onto the odor-producing solid or liquid odor source. In this case, the composition may be sprinkled by hand, but is usually applied using an appropriate tool such as a sprayer or atomizer.

[0018] The deodorant composition for solvent odors according to the present invention is not limited to the above-mentioned solution form, and can be used in any form such as solid, powder, gel, aerosol, etc., depending on the odor-generating target. A solid solvent odor deodorant composition can be obtained by impregnating a carrier with a solution solvent odor deodorant composition and storing the impregnated carrier in a suitable container. Carriers used for this purpose include inorganic porous carriers such as activated carbon, zeolite, alumina, diatomaceous earth, calcium silicate, glass fiber, and unglazed pottery, as well as organic carriers such as animal and vegetable waxes, petroleum waxes, higher fatty acids, sugar esters, and filter paper. The gel-type solvent odor deodorant composition can be obtained by impregnating or supporting agar, carrageenan, silica gel, gellan gum, gelatin, cellulose derivatives, polysaccharide gel, metal soap, polyvinyl alcohol, water-absorbent polymers, etc. with the solution-type solvent-proof odor deodorant composition, and storing the resultant in a suitable container. The aerosol solvent odor deodorant composition can be obtained by filling a pressure-resistant container with the liquid or powder solvent odor deodorant composition and a propellant such as liquefied propane gas, dimethyl ether, carbon dioxide gas, or compressed air. Furthermore, by using a natural or synthetic host compound such as cyclodextrin that can encapsulate the deodorant composition for solvent odors according to the present invention, a powdered deodorant composition for solvent odors can be produced.

[0019] The deodorant composition for solvent odors according to the present invention may further contain other fragrances, if necessary. Examples of such fragrances include terpinyl acetate, terpineol, camphor, acetaldehyde ethylhexenyl acetal, cis-jasmone, dipropylene glycol, diethylene glycol monoethyl ether, methyl dihydrojasmonate, and benzyl benzoate, and any other fragrances may be added depending on the intended use as long as they do not conflict with the objectives of the present invention. Furthermore, the solvent odor deodorant composition according to the present invention may further contain, if necessary, preservatives, bactericides, thickeners, natural or synthetic colorants, emulsifiers, etc. For example, examples of preservatives and bactericides include one or more of zinc pyrithione, benzalkonium chloride, cetylpyridinium chloride, etc.

[0020] The deodorant composition for solvent odors of the present invention is preferably used to deodorize coke odors, because although the deodorant composition for solvent odors of the present invention effectively deodorizes both organic solvent odors and coke odors, it can more effectively deodorize coke odors containing multiple components.

[0021] When the solvent odor deodorant composition of the present invention is a coke odor deodorant composition, it preferably contains dihydrojasmone, γ-methylionone, isoamyl salicylate, styrallyl acetate, anisyl acetate, cis-3-hexenyl salicylate, methyl 2-octynoate, methyl (Z)-3-hexenyl carbonate, and linalool as fragrance components. This is because the inclusion of nine fragrance components can more effectively deodorize the coke odor, which is an odor containing multiple components.

[0022] The present invention also relates to a method for deodorizing solvent odors, characterized by spraying, atomizing, or adding the solvent odor deodorant composition. When the deodorizing method is spraying or spraying, the solvent odor deodorant composition may be in solution form when used, and a solution deodorant composition for solvent odors may be used undiluted or diluted, or a solid solvent odor deodorant composition may be used by dissolving it in a solvent such as water or alcohol. When the deodorizing method involves adding the solvent odor deodorant composition, the solvent-containing deodorant composition may be in either solution or solid form, and can be used in a form that is easy to add.

[0023] The present invention will be explained below based on experimental examples, comparative experimental examples, working examples and comparative examples, but the present invention is not limited to these. [Example]

[0024] [Deodorization test of various fragrance ingredients against organic solvent odors] (Experimental Examples 1 to 5 and Comparative Experimental Examples 1 and 2) The deodorizing effect of each fragrance component listed in Table 1 below on xylene was measured as follows. (1) Xylene was placed in a 1 L sampling bag filled with odorless air so that the concentration was as shown in Table 1 below, and the bag was left standing in a high-temperature bath at 50°C for 1 hour to prepare an odorous gas. (2) 5 g of the stock solution of each fragrance ingredient listed in Table 1 below was placed in a 1 L Erlenmeyer flask, which was then sealed with a silicone stopper. 20 ml of the odorous gas (xylene gas) prepared in (1) above was placed in the 1 L Erlenmeyer flask. (3) After leaving the mixture at room temperature (25°C) for 30 minutes, the concentration of the odorous gas was measured using a detector tube. In Comparative Experimental Example 1 (blank), none of the above fragrance ingredients were added. In Comparative Experimental Example 2 (water), 5 g of water was added instead of the above fragrance ingredients. (4) The obtained xylene concentration was applied to the following formula (I) to calculate the deodorizing rate in comparison with Comparative Test Example 1 (blank) or Comparative Test Example 2 (water). The obtained results are shown in Table 1 below. Formula (I): Deodorizing rate (%) = (blank (water) concentration result - measured concentration result / blank (water) concentration result × 100
