Description

  The present invention relates to a liquid fragrance used in a house such as a toilet or a washroom or in a car.

Various forms, such as liquid, solid, and aerosol, are known as fragrances. Among these, the liquid type is further roughly divided into an oil base, an alcohol base and a water base. In addition, as a volatilization method, a fragrance component and a deodorant component are sucked up by using a capillary absorption phenomenon using a liquid-absorbing sucking member such as cellulose fiber or synthetic fiber, and led to an open volatilized body to volatilize naturally. In addition, a method of applying heat to a liquid, a method of forcibly volatilizing a volatilized body by sending wind with a fan or the like are known. However, in the market, the type that volatilizes naturally on a water basis is the mainstream for reasons such as cost and simplicity. In this type, since most of the fragrance materials are substantially hardly soluble in water, the fragrance is solubilized or emulsified in water using a surfactant or the like, and led to a volatilized body released through the sucking member. The function as a fragrance is exhibited by volatilizing the solution or emulsion. The technology for solubilizing fragrances in water using surfactants is a technology that is widely applied in many industrial fields such as foods, pharmaceuticals, and cosmetics. As surfactants, it is easy to form micelles from low concentrations. An ionic surfactant is preferable (Non-patent Document 1), and a combination of propylene oxide or ethylene oxide addition-type nonionic surfactant and a polyol such as glycerin or 1,3-butylene glycol is preferable (Non-patent Document 1). Document 2) is known.

  In order for a fragrance to be perceived by humans as an “odor”, the molecules of individual fragrance components are volatilized and reach the human olfactory organ, and are only recognized as an “odor” after stimulating the olfactory organ. The The balance of the individual fragrance components at this point is extremely important, and if this balance is changed, it may be recognized as a different “odor”. On the other hand, the blended fragrance is usually blended so that a desired fragrance can be expressed by mixing several tens of fragrance ingredients. Therefore, it is important to maintain the same “odor” that the individual flavor components solubilized or emulsified always evaporate in the same way. However, a conventional liquid air freshener that volatilizes a fragrance component by a method in which a solution obtained by solubilizing or emulsifying a conventional fragrance in water is led to a volatilized body released through a suction member and the fragrance solution or emulsion is volatilized. In the case of fragrances, the odor of a fragrance solubilized or emulsified with a surfactant or the like differs from the odor of the fragrance itself in strength or fragrance, or the fragrance changes during use and the fragrance It is known that there is a drawback that it becomes weaker or loses its freshness. This is because the part of the surfactant micelle to be solubilized varies depending on the difference in the physicochemical properties of the fragrance component, so that the volatility of each fragrance component changes (Non-Patent Document 3), and the fragrance It is considered that accumulation of non-volatile components such as surfactant remaining after the solubilized liquid volatilizes the fragrance and water from the surface of the volatilizer greatly affects the volatilization of the fragrance. Therefore, when used as a fragrance, there is a strong demand for the development of a liquid fragrance that can maintain the original fragrance balance of a blended fragrance and can maintain the fragrance balance from the beginning to the end of use.

  On the other hand, it has been known for a long time that an oily substance solubilized or emulsified with a surfactant or the like comes into contact with a demulsifier, and examples of the substance having a demulsifying action include an electrolyte. (Non-Patent Document 4). Further, as an example of utilizing the demulsification action in the perfume field, the use of the demulsification action may include a perfume emulsified in a detergent powder and a demulsifier in advance, and the perfume can be dissolved in water at the time of use. Has been proposed to release the aroma by demulsifying (Patent Document 1). In addition, as a technique that uses a method for releasing aroma by contact with minerals, oxygen gas generated when peroxides such as sodium percarbonate are dissolved in water by mixing peroxide and powdered fragrance To increase the volatility of the fragrance (Patent Document 2), fragrance is pre-particled with dextrin and polymer substance, and surfactant, inorganic salt and acid are further included in the particle and dissolved in water A method (Patent Document 3) for aromatizing when performing the process has been proposed. However, all of the methods described in Patent Documents 1 to 3 are techniques relating to detergents or powdery fragrances. In liquid fragrances, the original fragrance balance when blended is maintained, and from the beginning to the end of use. Until now, the liquid fragrance | flavor which can maintain the fragrance balance is not indicated.

The amount of the fragrance cannot be generally specified, but for example, it is in the range of 0.1 to 20% by weight, preferably in the range of 0.5 to 10% by weight, based on the total weight of the solution in which the fragrance is solubilized or emulsified. Can be illustrated.

  The type of surfactant used for solubilization or emulsification of the fragrance is not particularly limited, and is a nonionic surfactant, an anionic surfactant, a cationic surfactant, an amphoteric surfactant, and these. These surfactants can be widely used in combination at any ratio. Among these combinations, a nonionic surfactant or a combination of a nonionic surfactant and an anionic surfactant is particularly suitable for exerting the demulsification action suitably.

  The nonionic surfactant is not particularly limited, but a surfactant having an HLB of 9 to 18, preferably 10 to 16, or a combination of surfactants having different HLBs to give an HLB of 10 to 16. Can be illustrated. For example, polyoxyethylene alkyl phenyl ether (having an average addition mole number of ethylene oxide of 5 to 20), polyoxyethylene alkyl ether (having an average addition mole number of ethylene oxide of 2 to 30), polyethylene glycol fatty acid ester (of ethylene oxide) Polyoxyethylene hydrogenated castor oil (with an average addition mole number of ethylene oxide of 10 to 60), polyglycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester (average addition of ethylene oxide) Those having 6 to 20 moles), sucrose fatty acid esters, alkyl glycosides, fatty acid alkanolamides and the like, and the alkyl group of these nonionic surfactants preferably has 12 to 18 carbon atoms, Linear, branched Of appropriate chain length, solubilization capacity, are used appropriately selected from the viewpoints of solubilizing stability.

  Further, the anionic surfactant is not particularly limited. For example, alkylbenzene sulfonate, alkane sulfonate, alkyl sulfate ester, polyoxyethylene alkyl ether having an alkyl group chain length of 6 to 12 carbon atoms. Sulfuric acid ester salts (those having an average addition mole number of ethylene oxide of 1 to 8), alkyl phosphate ester salts, polyoxyethylene alkyl phosphoric acid ester salts (those having an average addition mole number of ethylene oxide of 1 to 8), alkylsulfosuccinic acid Salts, polyoxyethylene alkyl ether carboxylates (those with an average addition mole number of ethylene oxide of 1 to 10), alkyloyl sarcosine salts, alkyloyl methyl taurine salts, alkyl isethionate esters, alkyloyl glutamates, etc. be able to. Examples of the counter ion of these anionic surfactants include alkali metals such as sodium and potassium, alkanolamines such as ammonia, monoethanolamine, diethanolamine, triethanolamine and triisopropanolamine.

  Although it does not specifically limit as a cationic surfactant, For example, the alkyltrimethylammonium salt whose alkyl group chain length is C6-C12, a dialkyldimethylammonium salt, an alkylbenzyldimethylammonium salt etc. are illustrated. Examples of counterions of these cations include halides such as chlorides and bromides, hydroxides, perchlorates, and the like, with chlorides being preferred.

  Examples of amphoteric surfactants include, but are not limited to, betaine-type amphoteric surfactants, amino acid-type amphoteric surfactants, imidazoline-type amphoteric surfactants, and the like. Examples thereof include alkylcarbobetaines, alkylsulfobetaines, alkylhydroxysulfones. Examples include betaine, alkylamidocarbobetaine, alkylamidosulfobetaine, alkylamidohydroxysulfobetaine, alkylamidoamine type betaine, and alkylimidazoline type betaine.

  The amount of the surfactant used in the present invention can be appropriately selected depending on the amount of the fragrance to be solubilized or emulsified, but is usually in the range of 0.5 to 5 parts by weight, preferably 1 part by weight of the fragrance. It is preferable to mix | blend in 1-3 weight part. If the surfactant is significantly larger than this range, demulsification is less likely to occur when it comes into contact with or mixed with a component having a demulsifying action, and there is a possibility that oil droplets of the fragrance component are less likely to be generated. In addition, when the surfactant is significantly less than this range, the solubilization or emulsification of the fragrance is insufficient, so that the solubilization or emulsification breaks during storage even before being contacted or mixed with a component having a demulsifying action. May be separated.

  In the present invention, the solution in which the fragrance is solubilized or emulsified as described above is brought into contact with or mixed with a component having a demulsifying action to produce oil droplets of the fragrance component, and a fresh “odor” is scented. . The most common principle for destroying solubilization or emulsification by acting a demulsifier on a perfume solubilized or emulsified with a surfactant is to prevent hydration of the hydrophilic part of the surfactant. It is widely known that an electrolyte is preferably used for this purpose. The electrolyte that can be used in the present invention does not need to be special, and a general one can be used, for example, aluminum sulfate, sodium sulfate, calcium sulfate, magnesium sulfate, ammonium sulfate, sodium chloride, magnesium chloride. , Calcium chloride, ammonium chloride and the like can be used. Of these, aluminum sulfate, sodium sulfate, and sodium chloride are particularly preferably used. Further, when an anionic surfactant is used as the surfactant at a particularly high concentration, a calcium salt or a magnesium salt may be used.

  In the present invention, the liquid fragrance solution in which the fragrance component is solubilized or emulsified and the component having a demulsifying action must be separately arranged before the start of use as a fragrance in order to avoid contact and mixing of both. There is. Further, after the start of use, the liquid fragrance solution in which the fragrance component is solubilized or emulsified needs to be gradually contacted or mixed with the component having a demulsifying action little by little. By gradually contacting or mixing, it becomes possible to continue to smell a fresh “odor” from the beginning to the end of use over a long period of time. Therefore, any method or structure may be adopted as long as the liquid fragrance solution in which the fragrance component is solubilized or emulsified is gradually brought into contact with or mixed with the component having a demulsifying action. The following can be illustrated as a structure which can perform a simple contact or mixing. That is, a liquid fragrance in which a component having a demulsifying action is arranged on the surface or inside of the volatilizing body, and a lower part of the volatilizing body has a sucking member connected to the volatilizing body, solubilizing or emulsifying the fragrance component It is a structure which contacts or mixes both by sucking up a solution with a suction member. In this structure and method, a solution in which a fragrance is solubilized or emulsified is brought into contact with or mixed with a component having a demulsifying action that is sucked up by the capillary action of the sucking core and added to the inside or the surface of the volatilized body opened to the outside. As a result, demulsification occurs, and oil droplets of the fragrance are separated in the volatilized body, and a fresh “odor” is scented from the oil droplets. In addition, this structure and method do not require any special sucking core or volatilization body, and the sucking core or volatilization body made of cellulose fiber or synthetic fiber conventionally used for liquid fragrances is used as it is. Can be used.

  The concentration of the component having the demulsifying action in the present invention may be any concentration that can demulsify the solution in which the fragrance is solubilized or emulsified. The type of demulsifier, the type and concentration of the surfactant used, and the type of fragrance It depends on the concentration. Furthermore, since the fragrance and water separated by the demulsification action are volatilized sequentially from the volatilization body, the demulsifier remains in the volatilization body, and the surfactant gradually accumulates, so it is difficult to determine theoretically. . However, it is possible to prepare several samples with different blending amounts of components having demulsifying action and determine the blending amount while observing changes in the quality of “odor”. The amount of the component having a demulsifying action is usually within the range of about 1 to 100 parts by weight, preferably 2 to 50 parts by weight, per 100 parts by weight of the surfactant contained in the solution in which the fragrance is solubilized or emulsified. Within the range, the object of the present invention can be achieved.

The liquid fragrance of the present invention can be blended with various additives usually used in fragrances as long as the effects of the present invention are not hindered. Examples of such additives include sequestering agents, pH adjusters, antioxidants, antiseptics, deodorants, antibacterial agents, solvents, hydrotope agents, ultraviolet absorbers, dyes, insecticides, insecticides, repellents. Etc. can be illustrated.
Hereinafter, the present invention will be described more specifically with reference to examples. In addition, these Examples do not limit this invention at all.
