Description

Hybrid air freshener composition having constant and long exhalation property

1 is a graph showing the fragrance retention rate over time of the gel fragrance and flavor capsule,

2 is a graph showing the fragrance retention rate over time of the composite fragrance.

The present invention relates to a composite fragrance composition and a method for producing the same in combination with a gel-type fragrance or a liquid fragrance and flavor capsules to exhibit a uniform divergence characteristics for a long time.

In recent years, the use of air fresheners is increasing not only in odor spaces such as toilets, but also in general offices, homes, vehicles, businesses, etc., as living standards and higher quality of life are emphasized. As an easy example, the impact of odors from building materials, which have not been noticed on the health, has become a social issue, so the term 'new house syndrome' has become widely used, and consumers' interest in health and desire for a pleasant living environment are higher than ever. Can be. In particular, aromatherapy for stress, relaxation and concentration in modern life is receiving new attention, and the development of fragrances with various effects and the development of fragrance manufacturing technology are steadily being made.

A fragrance is a product that vaporizes perfume for a certain period of time with a certain strength. Most of the fragrance materials are easily volatilized, so it is difficult to maintain the fragrance for a long time in a general environment. Therefore, the issue in the fragrance technology field is to improve the appearance of fragrance and to maintain a certain intensity of flavor for a long time, and various technologies are being developed to improve the fragrance duration.

The fragrance can be a liquid fragrance diluted with an alcohol or other solvent, a gel fragrance with fragrance dispersed in a gelling agent, a silica gel, a porous polymer, a porous ceramic, a felt impregnated fragrance impregnated with a felt, or a wood, and a fragrance dispersed therein. Aerosol injected with gas, flavor capsules encapsulated with a polymeric substance. These products all help to control the fragrance intensity and to extend the fragrance duration, but most of the initial fragrances are strong and the fragrance tends to weaken over time.

Liquid fragrance is easy to manufacture, but the container must be securely fixed, the initial fragrance is too strong and has a disadvantage that the fragility of the fragrance due to the acid is fast. Therefore, in addition to the fundamental disadvantage that the liquid fragrance can be polluted by pouring from the container, a device that ejects or discharges a certain amount of fragrance mixture every certain time is required to be difficult to use in homes and vehicles. On the other hand, combustible gas used as a filling gas is not only hygienic but also risk of explosion, so the production and distribution of gas products will be completely prohibited.

In contrast, gel fragrances are easy to handle and safe for consumers, can be freely contained in various containers, can be freely manufactured in color or appearance, and have a relatively long fragrance duration. Gel fragrances are of an aqueous type and an oil type. Aqueous type can be made of transparent gel, so it has excellent characteristics in terms of decoration, but since water is used as a matrix, the volatilization speed of fragrance is high and it dissipates faster in summer, thus increasing the volume of the product. The oily gel is oily oil as a matrix and can carry fragrance for a long time, so it is widely used in household, vehicle, and business. However, the oil gel is also subject to improvement of constant fragrance strength over time and still insufficient fragrance duration.

To compensate for these drawbacks, the fragrance is used by adsorbing or encapsulating the polymer material. In particular, the flavor capsule has the advantage of controlling the divergence time according to the type of capsule material and the thickness of the capsule wall, and the size of the particles can be manufactured from several millimeters to several tens of micrometers. It can be applied to wallpaper, clothing, and the like. However, fragrance capsules can not be manufactured in a variety of appearances and colors as well as a high manufacturing cost has a disadvantage in that the cost cost of the consumer to use the fragrance capsule alone.

Korean Patent No. 0431360 describes a sustained-release fragrance resin composition containing a fragrance powder and microencapsulated fragrance microcapsule powder. Korean Patent No. 0120275 discloses a spray of a persistent fragrance and deodorant using microcapsules in which aromatic and deodorant substances are placed inside microcapsules and suspended together with a small amount of binder for the purpose of spraying clothes, sheets, and the like. In Korean Patent No. 0688951, the fragrance of a gel-type aroma and deodorant composition containing aroma and deodorant components in a polymer matrix, and No.0507318 are excellent in fragrance sustainability prepared by mixing and stirring a styrene-isoprene copolymer, isoparaffin, and a perfume. A fragrance composition of the oily gel type and a preparation method thereof are disclosed. Patent No. 0422306 discloses a pasty fragrance composition having excellent fragrance persistence, in which a sustained release material containing fragrance is semi-coated with a water-soluble polymer material to form a paste, thereby suppressing volatilization of the fragrance and allowing a long-lasting aroma to be consistently long. . The fragrance techniques presented in these conventional patents still have problems as described above in terms of deterioration of constant fragrance intensity over time or fragrance duration time, or have a problem that is difficult to be generalized due to cost problems.

The present invention can control the divergence time of the fragrance material according to the type of the gel fragrance and the capsule material and the thickness of the capsule wall, which can be easily handled by consumers and can be freely contained in various containers and can be freely made in color or appearance. The purpose of the present invention is to provide a fragrance composition and a method for manufacturing the same, which can realize aesthetic appearance and various forms of products, maintain a constant fragrance strength over time, and maintain volatilization for a long time.

In addition, the present invention by producing an effective fragrance capsule that can uniformly control the emission of the fragrance substance over a long time, there is an advantage that the conventional manufacturing is easy, but the initial fragrance strength is too strong and the fragility of the fragrance strength according to the base acid is fast and stable It is an object of the present invention to provide an effective fragrance composition that takes advantage of the liquid fragrance that has been insufficient to be used as a fragrance and has a disadvantage.

In particular, the present invention is a composite support and release system consisting of a gel fragrance or a liquid fragrance with a high initial fragrance divergence, and a fragrance constant and continuous fragrance capsules for a long time while minimizing the increase in the cost of using expensive fragrance capsules The purpose is to maintain a constant fragrance intensity.

In addition, an object of the present invention is to provide a fragrance composition that effectively supports and releases a variety of fragrance substances with respect to the improvement of sick house syndrome or aromatherapy with such a complex support and release system.

Other objects and advantages of the present invention will be described below and will be better understood by practice of the present invention.

In the present invention,

(a) D-limonene; 3-Methoxy-3-methyl butanol (3-MMB); Oily gel fragrance or carrageenan in which a fragrance oil is mixed and dispersed in a substrate selected from the group consisting of isoparaffin; gelatin; There is provided a fragrance composition comprising 95 to 50 parts by weight of an aqueous gel fragrance in which the fragrance is mixed and dispersed in an aqueous substrate selected from the group consisting of agar, and 5 to 50 parts by weight of (b) aroma capsules.

In the present invention,

Fragrance oils; Melamine type; The perfume composition which disperse | distributed the fragrance | capsule encapsulated with the polymer resin selected from an epoxy system in a liquid perfume is provided.

In the present invention, the "flavor capsule" is a particle size of the oil-soluble fragrance oil is surrounded by a polymer membrane, the diameter of the capsule may have a variety of sizes from several tens of nm to several mm, depending on the application, the boundary between the wall material and the inner material It includes both a clear, fully encapsulated form and a matrix-like encapsulation in which the boundary between the wall and the inner material is not clear and continuous.

The oily gel fragrance of the present invention is prepared by mixing and dispersing a fragrance oil on a d-limonene or 3-MMB (3-Methoxy-3-methyl butanol) substrate. Preferably, the oily gel fragrance uses a mixed substrate of d-limonene and 3-MMB. Alternatively, a mixture of isoparaffin (G or E) and d-limonene may be used instead of the d-limonene and 3-MMB mixture. The oily gel fragrance is preferably sodium stearate as the gelling agent. Preferred compositions of the oily gel fragrance include sodium stearate 2.5 to 3.0 parts by weight; 40 to 60 parts by weight of d-limonene; 25 parts by weight of 3-MMB and 10 parts by weight to 22 parts by weight of fragrance oil, and in appearance, preferably 1 to 2 parts by weight of dye. The mixture of d-limonene and 3-MMB can be controlled at a ratio of approximately 75 parts by weight, and the volatilization rate can be adjusted according to the ratio.

Oil gel fragrance preparation method is sodium stearate, d-limonene, 3-MMB, dye is added to a heat mixer, heated to a temperature of 90 ~ 100 ℃ to completely dissolve the fragrance oil. When it is determined that the fragrance oil is evenly dispersed in the mixture, the mixture is discharged from the discharge port, filled into a desired container, and cooled at room temperature. Note that the preparation of gel fragrances is whether the reactor is sealed and the temperature of the mixture in the reactor when the fragrance is added. If the reactor is not enclosed, not only does the fragrance dissipate, but the fragrance concentration is deteriorated. On the other hand, the composition ratio and manufacturing method of the oil gel used in the present invention is not necessarily limited to the above preferred examples.

The fragrance used in the oily gel fragrance or the aqueous gel fragrance of the present invention, the fragrance capsule may be a general fragrance or natural aromatic fragrance oil. In particular, phytoncide, which has recently attracted much attention, can also be used. Specific examples of fragrances that may be used include jasmine, lemon, peach, lavender, orange, German chamomile, phytoncide, and any other fragrance oils of suitable utility. The advantage that oil gel has over water gel is that it can be applied to a variety of fragrance oils without any particular problem, and stearate gel can support up to 60 parts by weight or more of fragrance, and has a much higher fragrance carrying capacity than aqueous gel. It is big. However, the manufacturing process is disadvantageous and expensive compared to the aqueous gel.

The aqueous gel fragrance of the present invention uses carrageenan, gelatin, agar and the like as a matrix. Since the aqueous gel is 60 to 70% of the total weight of water, the volatility is large, so the fragrance duration is short, and there is a fundamental problem that it cannot contain a large amount of fragrance because the fragrance supporting oil is mostly oily. Nevertheless, the aqueous gel can be manufactured transparently, and the appearance is remarkable, so that the decorative effect is less, and there is less risk in manufacturing than the oil-based gel.

Preferred compositions of the aqueous gel perfume are carrageenan; gelatin; 2 to 4 parts by weight of the substrate selected from agar, 3 to 6 parts by weight of ethylene glycol, 50 to 80 parts by weight of water, 1 to 5 parts by weight of fragrance oil, and 5 to 12 parts by weight of the crosslinking agent. The preferred method for preparing the aqueous gel fragrance is as follows. However, the composition ratio and preparation method of the aqueous gel fragrance are not limited to these preferred examples.

First 2 to 4 parts by weight of gelatin; 3 to 6 parts by weight of ethylene glycol; The mixture of 50 to 80 parts by weight of water is heated to 60 to 70 ° C to dissolve, and then a mixture of 10 to 15 parts by weight of ethanol and 1 to 5 parts by weight of fragrance oil is added. After the necessary amount of dye, preservative, antifoaming agent, etc. are added to the mixture, the mixture is stirred and mixed thoroughly. Finally, 5 to 12 parts by weight of isobalm, a crosslinking agent, is added, stirred, and filled into the required container. The gel forms a complete gel 24 hours after standing at room temperature. When carrageenan or agar is used, it is used to form translucent gels, unlike gelatin. Unlike aqueous gels, aqueous gels dissolve at high temperatures and add flavors in an emulsified or solubilized state. Therefore, it is difficult to manufacture a product with a high content of fragrance because the content of the gelling agent should be lowered and the water content should be high.

The fragrance capsule used in the present invention is a fat-soluble fragrance oil is surrounded by a polymer membrane and granulated, and the diameter of the capsule can be variously manufactured from several tens of nm to several mm depending on the use. The biggest advantage of the flavor capsule is that the release rate of the incense can be arbitrarily adjusted according to the thickness and type of the capsule wall. The capsule wall is composed of natural polymers such as cellulose, chitosan, and alginic acid, or synthetic polymers such as polyurethane, melamine, and epoxy, and internal materials may be general synthetic, natural, and other organic substances. Preferably, the capsule wall may be composed of a thermosetting polymer resin or a thermoplastic polymer resin, and in particular, may be composed of a polyurethane-based or melamine-based polymer resin.

The diameter of the fragrance capsule is determined by the fragrance oil, the wall material, the emulsifier, the stirring speed, and the temperature, and the full capsule type having the boundary between the wall material and the internal material is most advantageous for controlling the fragrance release rate. Matrix capsules may be produced in which the boundary between the wall material and the inner material is not clear and continuous. In other words, the structure of the capsule can be either a closed cell or an open cell.

The flavor capsule used in the present invention is preferably prepared as follows. However, the composition or manufacturing method of the flavor capsules is not limited thereto. First natural polymer or polyurethane-based; Melamine type; 1 to 3 parts by weight of the polymer resin selected from epoxy, 0.5 to 2 parts by weight of sodium hydroxide, and 40 to 50 parts by weight of water are mixed well, and then 30 to 40 parts by weight of fragrance oil is added and stirred to emulsify the fragrance. To this reaction, 4-5 parts by weight of formalin, 0.1-0.5 parts by weight of sodium hydroxide, 2-3 parts by weight of melamine, and 2-4 parts by weight of triethylamine are added, and the aromatic oil is encapsulated by stirring while heating to 40-80 ° C. Particles are obtained.

In addition, a typical production example of the flavor capsule using a melamine-based polymer resin is as follows. First, 1 to 3 parts by weight of SMA (styrene-maleic acid copolymer), 0.5 to 2 parts by weight of sodium hydroxide, 40 to 50 parts by weight of water are mixed well, and then 30 to 40 parts by weight of fragrance oil is added. The temperature of the mixture is maintained at 40-50 ° C. and stirred for about 30 minutes to emulsify the fragrance. After adding 4-5 parts by weight of formalin, 0.1-0.5 parts by weight of sodium hydroxide, 2-3 parts by weight of melamine, and 2-4 parts by weight of triethylamine, the mixture was stirred at 50-60 ° C. for 10 minutes, and then the temperature was 60-70. It raises to ° C and stirred for 2 to 5 hours. The diameter of the obtained particles is 0.1 to 2 micrometers depending on the detailed conditions. The fragrance capsule of the present invention thus prepared may exhibit a sufficient duration extension effect even when mixed in a liquid fragrance.

The liquid fragrance (or liquid fragrance) used in the present invention may be prepared by a general liquid fragrance manufacturing method in which the fragrance is diluted in alcohol or other solvents. In one embodiment of the present invention was prepared by diluting and dispersing the fragrance oil in a mixed solvent of ethyl alcohol and water.

Hereinafter, the present invention will be described in more detail with reference to specific examples. However, the scope of the present invention is not limited by the following examples, and those skilled in the art to which the present invention pertains should be within the equivalent scope of the technical concept of the present invention and the claims to be described below. Of course, various modifications and variations are possible.

Example  1 to 2

Gel fragrance  Produce

Gel perfume was prepared according to the contents described in Table 1. The contents except the fragrance oil were heated and stirred to dissolve all at 90 ℃, the temperature was lowered to 60 ℃ and then the fragrance oil was added, stirred and mixed thoroughly, and put in a container through the discharge port and cooled at room temperature. The prepared fragrances all had a translucent gel shape at room temperature and did not change form even when left for about 12 hours at about 50 ℃ or more.

Example  3

Preparation of flavor capsule

2 parts by weight of SMA (styrene-maleic acid copolymer), 0.6 parts by weight of sodium hydroxide, 47.75 parts by weight of water were mixed well, followed by the addition of 33.81 parts by weight of fragrance oil (US Cholester SD-75XL). The mixture was kept at 40 ° C. and stirred for 30 minutes to emulsify the fragrance, and then 4.80 parts by weight of formalin, 0.14 parts by weight of sodium hydroxide, and 2.24 parts by weight of melamine were added thereto, and the pH was maintained at 7.8 to 8.0. The reaction was carried out for a minute. The temperature of the mixture was raised to 65 ° C., followed by further reaction for 3 hours, and then 1.10 parts by weight of triethylamine and 1.77 parts by weight of salt were added and mixed well with the mixture. The obtained capsules were hard particles having a diameter of 1 to 2 mm.

Example 4

Of flavor capsule  Produce

Same as Example 3, but 67g of the amount of fragrance oil was used. The obtained capsule was hard particles having a diameter of about 2 mm.

Examples 5-8

Preparation of Complex Perfume Composition

As described in Table 2, the gel perfume and the capsules prepared in Examples 1 to 4 were mixed to prepare a composite perfume. In the preparation of the composite fragrance, after preparing the gel fragrance first, the separately prepared fragrance capsule particles are added to the reactor while the composition of the gel fragrance is sufficient at a temperature of about 50 ° C. in the reactor, followed by stirring again to evenly disperse the particles in the gel. It was put in the container through the discharge port.

Test Example  One

Percent Retention Percent Over Time

The fragrance rate of the fragrance composition prepared in Examples 1 to 8 was measured. The experiment was carried out by leaving the air freshener in a room with low air flow at 25 ° C. and measuring the weight loss at a given time every day for up to four weeks. Evaluated.

Table 3 and Figure 1 shows the results of the measurement of the flavor volatilization rate of Example 1 and Example 4 it can be seen that the flavor divergence time of the flavor capsule is much longer than the general gel fragrance. Gel fragrances have a high initial fragrance and the rate of divergence decreases over time because the fragrance concentration in the gel matrix decreases rapidly over time. On the other hand, in the case of encapsulated incense, the emission of the incense is properly controlled by the capsule wall, and it can be seen that the fragrance divergence rate is kept constant.

Test Example  2

Percent Residual Percentage of Compound Perfume

The fragrance divergence time extension effect of the fragrance capsule can be seen clearly in Table 4 and FIG. 2 measuring the fragrance duration of the complex fragrance mixed with the fragrance capsule and gel fragrance.

Example  9

23 parts by weight of fragrance oil (US Cholester SD-75XL), 300 parts by weight of ethyl alcohol, 200 parts by weight of distilled water. Agitated to prepare a liquid fragrance.

Example  10

10 parts by weight of the fragrance capsule prepared in Example 3 was added to 100 parts by weight of the liquid fragrance prepared in Comparative Example 1 to prepare a mixed fragrance in which the fragrance particles were dispersed in the liquid.

Test Example  3

The liquid and mixed fragrances prepared in Examples 9 and 10 were respectively placed in a container having a narrow inlet, and then allowed to stand at room temperature for 2 days, and then the strength of the fragrance was measured by liquid layer chromatography of liquid components in the liquid. As a result, in the case of Example 10, the perfume concentration in the liquid was about 30% or more higher than that of Example 9.

In the present invention, despite the various advantages such as appearance and ease of handling, the fragrance divergence time is still unsatisfactory and the liquid fragrance which has limited use as a gel fragrance or a continuous fragrance, while costly and difficult to manufacture, but fragrance It provides a new complex fragrance composition that combines the advantages of the fragrance capsules with an excellent divergence time and complements the disadvantages. The composite perfume composition of the present invention has a longer fragrance duration and a constant divergence concentration than a general gel type perfume or a liquid perfume, and can maintain a stable form for more than one month, thereby satisfying the needs of general consumers and commercial perfumes. Despite these effects, production costs can be significantly reduced compared to conventional capsule fragrances.
