Description

  The present invention relates to a liquid aroma deodorant composition, and further relates to a liquid aroma deodorant composition having excellent volatility.

  Various forms such as liquids, solids, and aerosols are known as aromatic deodorants. Among these, the liquid type is roughly divided into oil base, alcohol base and water base, and the method of volatilization of fragrance and deodorant components uses the capillary phenomenon and uses a core material made of pulp or synthetic fibers. There are known methods of sucking up the liquid, guiding it to an open volatilized body, volatilizing it naturally, and forcibly volatilizing it by applying heat or blowing with a fan. In the market, the method of volatilizing naturally on a water basis is the mainstream for reasons such as cost and simplicity. In this type, since the perfume is essentially poorly soluble in water, the perfume is solubilized in water using a surfactant, and the inside of the perfume is made through a liquid-absorbing core made of pulp, synthetic fiber, etc. The function is demonstrated by evaporating the solution. The technology for solubilizing fragrances in water using surfactants is a technology that is widely applied in the industrial field such as cosmetics and pharmaceuticals. As surfactants, nonionic surfactants that easily form micelles from low concentrations. It is described that an agent is preferable (Non-patent Document 1) and that 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 2). Therefore, nonionic surfactants are mainly used as solubilizers in current liquid aroma deodorants. However, surfactants are essentially non-volatile, and the liquid is sucked up by capillary action, and after fragrance and water evaporate from the open surface of the volatilization body, it accumulates in the volatilization body and gradually decreases liquid absorption and volatility. The problem remains that the fragrance remains without being volatilized to the end. If the amount of surfactant used is reduced, the amount of residual accumulation will decrease, and the adverse effect on liquid absorption and volatility will be reduced, but the perfume cannot be sufficiently solubilized, or stability problems will occur. . In order to solve such problems, improvements from surfactants, liquid absorbents and volatile structures used for solubilization have been proposed. For example, excellent solubilization ability can be realized by using an alkylene oxide adduct of an alkyl-substituted phenol (Patent Document 1), and a linear alkylbenzene sulfonate, a secondary alcohol ethylene oxide adduct, and a nonylphenol ethylene oxide addition Products, liquid fragrance compositions with good storage stability and good fragrance quality and sustainability by other combinations (Patent Document 2), and end-capped type in which the addition molar distribution of ethylene oxide is narrower than a specific condition Liquid fragrance deodorant composition characterized by blending nonionic surfactant (Patent Document 3), and also aimed at efficient volatilization by changing the material of the liquid absorbing material and volatilization structure Many proposals such as (Patent Document 4) have been made. However, since the technical contents disclosed in Patent Documents 1 and 3 use a fairly special surfactant, there are problems in cost and versatility, and the technique disclosed in Patent Document 2 is essentially the same. This is a technique for enhancing the stability of a liquid fragrance solubilized with a fragrance against coloring and separation. The liquid absorbing material and the volatilization structure disclosed in Patent Document 4 use special fibers in which different types of synthetic resins have a core-sheath structure.

  Conventionally proposed technologies related to liquid fragrance deodorants use special surfactants or use special members, which is problematic in terms of economy and is inevitable in the course of use. In the improvement with respect to the fall of liquid performance or volatilization performance, it was not fully satisfied.

  Liquid crystal phase, gel phase, crystal in the process in which a solution in which a fragrance is solubilized with a surfactant is sucked up by a liquid absorption core and volatile components (fragrance, ethanol, water, etc.) are volatilized and concentrated on the surface of the volatile member. It exhibits various aspects such as precipitation. The physical properties of these phases are affected in a complex manner by the type and concentration of the surfactant used, the type of fragrance, and other additives, and affect the liquid absorption performance and volatilization performance. Therefore, the problem to be solved by the present invention is that even if the solution is concentrated in the process of using the liquid fragrance deodorant, a change in physical properties that hinders volatility hardly occurs on the surface of the volatilized body. There is little clogging of a volatilization member, and it is providing the liquid aroma deodorizer from which a fragrance | flavor is volatilized stably to the last and a fixed fragrance is obtained.

  As a result of diligent research to solve the above-mentioned problems, the present inventors have blended propylene carbonate with a liquid aroma deodorant obtained by solubilizing a perfume or the like using a surfactant. The present inventors completed the present invention by discovering that the components such as these were stably volatilized.

  That is, the present invention provides a liquid aroma deodorant composition comprising 0.5 to 5.0% by weight of propylene carbonate in a liquid aroma deodorant solubilized with an oily substance such as a fragrance using a surfactant. It is to provide.

  According to the liquid aroma deodorant composition of the present invention, even if the liquid aroma deodorant composition is concentrated due to volatilization of components such as fragrance and water in the course of use, the liquid aroma deodorant is concentrated on the surface of the volatilized body. Change in the physical properties of the agent composition is unlikely to occur, resulting in less clogging of the suction core and the volatilizing member, and the perfume stably volatilizes to the end, thereby having the effect of reducing the perfume residue at the end of volatilization It is possible to provide a liquid fragrance deodorant composition having high consumer satisfaction in which the quality of the original scent lasts until the end.

  The liquid fragrance deodorant composition of the present invention contains propylene carbonate as an essential component. The blending amount of propylene carbonate is 0.5 to 5.0% by weight. When the blending amount of propylene carbonate is 0.5% by weight or less, there is no effect of preventing changes in physical properties that hinder the volatility of the liquid aroma deodorant composition during use, and the effect of maintaining the stable volatilization of the fragrance until the end is demonstrated. Can not. In addition, when the blending amount is 5.0% by weight or more, the effect of maintaining stable volatilization of the fragrance is good, but since the propylene carbonate is a non-volatile substance, the blending amount is increased and the liquid aroma deodorant composition is rather increased. The volatilization residue of things increases, which is not preferable.

  The surfactant used for solubilizing the fragrance and the fragrance used in the liquid fragrance deodorant of the present invention is not particularly limited. Usually, nonionic surfactants, anionic surfactants and the like are used alone or in combination as surfactants used for solubilizing fragrances and the like. For example, as the nonionic surfactant, a surfactant having an HLB of 9 to 18, preferably 10 to 16, or a combination of surfactants of different HLBs to obtain an HLB of 10 to 16 is used. .

  The method for producing the liquid aroma deodorant composition of the present invention is not particularly limited, and may be a solubilization process of an oil component using a general surfactant, that is, a fragrance in a predetermined amount of propylene carbonate, Mix the surfactant, and if necessary, warm or add a solvent such as ethanol to make it uniform. Heat it to a certain amount of water if necessary, and add it with stirring to obtain a transparent solubilized solution. I can do it.

  Hereinafter, embodiments of the present invention will be described more specifically with reference to examples. In addition, these Examples do not limit this invention at all.

(Examples 1-2 and Comparative Examples 1-6)
A liquid fragrance deodorant composition was prepared according to the formulation shown in Table 1 and Table 2, and tested for the volatility of the fragrance. The results of the volatility test are shown in Tables 1 and 2. However, the compounding quantity in Table 1 and Table 2 is weight%.
(Formulation method)
Thoroughly stir the fragrance, surfactant, ethanol and solvent until uniform. This is added to a predetermined amount of water with stirring to obtain a transparent liquid aroma deodorant composition.
(Volatilization test)
15.0 g of the liquid aroma deodorant composition obtained above is weighed in a petri dish having an inner diameter of 58 mm and a depth of 15 mm, and volatilized naturally in a thermostatic chamber at 25 ° C. After 164 hours, the volatilized residue is obtained when the amount is almost constant, and the remaining amount of the fragrance is calculated from the difference from the calculated non-volatile content. Here, the surfactants A, B, C, and D, and propylene carbonate, ethylene glycol, and dipropylene glycol are calculated as the nonvolatile content.

  As is clear from Tables 1 and 2, by blending propylene carbonate, the change in physical properties that hinders volatility is suppressed and stable volatilization of the fragrance is performed to the end, so the amount of the fragrance remaining at the end of volatilization is reduced. The effect is obvious. Example 1 and Comparative Examples 1 to 3 in Table 1 are systems solubilized with a nonionic surfactant, but in comparison with the case where ethylene glycol, dipropylene glycol and these solvents are not blended, propylene carbonate is used. When blended, there is clearly little perfume remaining at the end of volatilization. Moreover, although Example 2 of Table 2 and Comparative Examples 4-6 are the evaluation results about the system solubilized with the anionic surfactant, the stable volatilization of a fragrance | flavor is carried out by the mixing | blending of propylene carbonate like Example 1. The effect of reducing the amount of perfume remaining at the end and remaining at the end of volatilization was evident. Separately from this, when the volatilization test was performed for the case where the fragrance was not blended among the blended formulations of Example 1 and Example 2, the measured value of the volatilization residue almost coincided with the calculation amount.

Fragrance A: Orange No7769 Surfactant A manufactured by Hasegawa Fragrance Co., Ltd .: Polyoxyethylene oleyl ether (average added mole number of ethylene oxide is 20)
Surfactant B: Sodium dioctyl sulfosuccinate Surfactant C: Sodium linear dodecylbenzenesulfonate surfactant D: Volatilized residue of isostearic acid diethanolamide (actual value%): Value when almost constant weight after 164 hours Calculated non-volatile content (%): Non-volatile content calculated as surfactant and solvent (other than ethanol) Perfume residue (%): Volatilization residue-Calculated non-volatile content

(Examples 3-6 and Comparative Examples 7-10)
With the formulation shown in Table 3, a liquid aroma deodorant composition was prepared by changing the blending amount of propylene carbonate, and the volatility was tested in the same manner as in Examples 1-2. The results of the volatility test are shown in Table 3. However, the compounding amount in Table 3 is% by weight.
As apparent from Table 3, it was confirmed that when 0.5% by weight or more of propylene carbonate was blended, there was an effect of reducing the volatilization residue of the fragrance. In addition, when propylene carbonate exceeds 5.0% by weight, the amount of the volatile residue of the liquid aroma deodorant composition increases with the increase in the blending amount of propylene carbonate, which is a non-volatile substance, for the effect of reducing the volatile residue of the fragrance. You can see that increased.

The area of the open part of the volatilization body is 135 cm ² . The test results are shown in FIG.

  In Example 7 in which propylene carbonate was blended, it became clear that the stable volatilization of the fragrance continued to the end and its volatility was superior as compared with Comparative Example 11 not containing propylene carbonate. Moreover, when the quality of the fragrance was compared, in Example 7, the well-balanced fragrance immediately after the start of the experiment lasted until the end, but in Comparative Example 11, the balance of the fragrance collapsed over time, and finally the fragrance Alteration was also observed.

It is explanatory drawing which showed the effect which acts on the volatility of a propylene carbonate. (Example 7 and Comparative Example 11)
