Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gel fragrance capable of releasing a constant level of fragrance over a long period of time.

[0002]

2. Description of the Related Art Conventionally, gel fragrances have been frequently used from the viewpoint of safety and ease of handling. The gel-like fragrance is usually composed of a gelling agent, water as a carrier, a medium such as a solvent, a surfactant, a composition of a fragrance component, etc., and is heated and uniformly melted, then cooled and solidified. It is a thing.

[0003] In such a gel-like fragrance, the fragrance component evaporates together with the medium from the inside of the gel, but there is a problem that the amount of volatilization decreases with time and the fragrance becomes weak. To solve the above problem, Japanese Patent Application Laid-Open No.
As disclosed in Japanese Patent No. 160739, there is known an air-cleaning gel structure in which a layered distribution structure containing a higher concentration of a fragrance component and the like than an outer portion is formed in an inner portion with respect to an air contact surface. .

[0004] The use of the above gel structure compensates for the decrease in the amount of the fragrance component volatilized in the outer portion gel by supplying the fragrance component from the inner high concentration gel portion.
It is possible to maintain a certain level of fragrance over a long period of time.

[0005]

However, in general, in a gel-like fragrance, the gel shrinks with the volatilization of a volatile component (hereinafter, abbreviated as a volatile component) such as an aroma component and a medium, and the gel is used at the end of use. That is, near the end of the volatilization of the volatile component, a hard film composed of a non-volatile component such as a gelling agent or a surfactant is formed on the surface or entirely.

Therefore, in the gel structure having the above-mentioned structure, although the aromatic component in the inner high-concentration gel still remains in a considerable amount, the outer gel shrinks and forms a film, so that the gel is volatilized. Since the volatilization of the components gradually becomes difficult, and the finally remaining fragrance components are confined in the gel as it is, there has been a problem that a considerable amount of the fragrance components is not effectively used.

Therefore, an object of the present invention is to solve the above problem.

[0008]

In order to achieve the above object, in the present invention, a first gel portion containing an aromatic component and a second gel portion containing a higher concentration of an aromatic component than the first gel portion are provided. A gel-like fragrance comprising a gel-like part and both gel-like parts integrally formed such that a part or the whole of the surface of the second gel-like part is in contact with the first gel-like part; The first gel-like part forms a porous lump residue at the end of use.

The arrangement structure of each gel-like part is such that the first gel-like part is in direct contact with the external air in consideration of the purpose of use of the second gel-like part, which releases a certain level of scent over a long period of time. It is desirable that all or most of the second gel-like portion be in contact with the first gel-like portion, that is, be formed so as to exist inside the first gel-like portion.

As a specific arrangement structure of the gel-like portion, a laminated structure in which a first gel-like portion is laminated on a second gel-like portion formed in a layer shape, or a block-like first gel-like portion inside a first gel-like portion is provided. Examples thereof include a structure in which two gel-like portions are formed, a structure in which a plurality of second gel-like portions formed in a particle shape are dispersed in a first gel-like portion, and the like.

In the present invention, powder is mixed only with the first gel-like part of the above-mentioned gel-like fragrance so that a porous lump residue (hereinafter, abbreviated as a lump residue) is formed at the end of use. Things. That is, the present inventor blended the powder into the first gel-like portion, which had conventionally formed a film around the second gel-like portion, so that the aromatic component in the second gel-like portion even at the end of use. Have been found to volatilize smoothly through the porous portion of the lump residue, and the present invention has been completed.

When the gel-like fragrance having the above arrangement is used, immediately after the start of use, the volatile components mainly contained in the first gel-like portion volatilize, and a certain level or more of fragrance is drifted in the external air. Furthermore, at the end of use in a state where most of the volatile components have volatilized from the first gel-like portion, a non-volatile component and powder in the first gel-like portion form a massive residue portion,
Since the volatile components contained in the second gel-like portion volatilize smoothly through the bulky residue portion, it is possible to maintain a certain level of fragrance throughout the use period.

Regarding the mechanism by which volatile components evaporate from the second gel-like part, the drying is most advanced due to the capillary phenomenon due to the voids between the powder particles and the liquid absorbing property of the gelling agent in the first gel-like part. It is considered that the volatile component in the second gel-like portion is quickly sucked up to near the surface of the one gel-like portion, and the volatile component smoothly volatilizes in the external air in a state where the volatilization area is increased.

The reason that the powder is limited to the first gel-like part is that if the powder is mixed up to the second gel-like part, the second gel-like part is given liquid absorbing property. This is because smooth evaporation of volatile components is hindered. In particular, when a porous material is used as the powder as described below,
Since the powder actively holds the volatile component, the amount of the volatile component volatilized extremely decreases. Therefore, when powder is blended in the second gel portion, a certain level of fragrance cannot be maintained at the end of use.

The gel-like part in the gel-like fragrance includes:
The present invention is not limited to only the first gel-like portion and the second gel-like portion, and may include, for example, a third gel-like portion containing a volatile active ingredient other than the aromatic component.

Here, the volatile active ingredient includes, for example, a component (substance and / or mixture) which volatilizes and has some action and effectiveness on humans and other organisms. And deodorants.

The arrangement structure of the gel-like fragrance composed of the first gel-like part to the third gel-like part has at least the first gel-like part in consideration of the smooth volatilization of the fragrance component contained in the second gel-like part. It is desirable to adopt a structure in which the portion and the third gel-like portion are layered, and the second gel-like portion is integrally laminated therebetween.

A second gel-like part is interposed between the first gel-like part and the third gel-like part so that a part or all of the surface of the second gel-like part comes into contact with another gel-like part. If the powder is blended into at least one of the first gel-like part or the third gel-like part to form a lump residue at the end of use, the volatilization of the aroma component is ensured. can do.

However, when powder is blended in the gel portion of the uppermost layer, depending on the particle size and specific gravity of the powder used, the powder begins to settle before the molten gel portion composition solidifies, When the portion is solidified, there is a possibility that the powder is unevenly distributed in the lower portion of the uppermost layer. If the degree of uneven distribution of the powder is large, the non-volatile component coats the surface of the lump when a lump residue is formed, preventing smooth evaporation of the aroma component.

Therefore, in the present invention, the gel-like portion containing the powder is the lowermost layer, and the second gel-like portion and the gel-like portion not containing the powder thereon (hereinafter, referred to as the upper gel portion). Can be adopted in which a gel-like fragrance obtained by integrally laminating is fixed around a core material erected on the bottom of the container.

When a gel-like fragrance having such a structure is used, the gel-like portion containing the powder shrinks to a predetermined volume to form a lump residue portion and does not shrink any more. As the shrinkage further progresses, the lump residue gradually curves upward.

Finally, since the film formed by the upper layer-side gel-like portion adheres to the core material, the lower surface of the massive residue portion is separated from the bottom of the container with the portion as a fulcrum to form a bowl-like massive residue portion. I will be.

That is, if the gel-like part containing the powder is the lowermost layer, even if the powder is slightly unevenly distributed in the lower part of the layer, the lower surface of the bulky residue part, which is a porous part, is located above the bottom of the container. Since it comes into contact with external air at a distance, it is possible to provide an unconventional gel-like fragrance that can ensure smooth volatilization of the fragrance component with an increased volatilization area.

As the gelling agent used in the present invention, an aqueous or oil-based gelling agent can be arbitrarily selected.
Although not particularly limited, for example, carrageenan, agar, locust bean gum, polyvinyl alcohol, gum arabic, gellan gum, gelatin, polyurethane, amino acids, carboxymethylcellulose and its metal salts, sodium alginate and the like may be used alone or in combination. be able to.

The material of the powder is not particularly limited, and either an organic material or an inorganic material may be used. Also, the shape of the powder particles is not particularly limited, and may be in an irregular shape, a needle shape, a spherical shape, a scale-like shape, or a short fiber shape.

With respect to the average particle size of the powder, the smaller the particle size, the better the liquid absorbing property. However, if the particle size is too small, the thickening action becomes large and it becomes difficult to uniformly mix the gel composition. It may be appropriately adjusted while observing the balance between the liquid absorbency and the workability when blended into the gel composition. Generally, it is desirable that the average particle size of the powder is 10 to 500 μm, and particularly preferably 100 to 200 μm.

Since the amount of the powder varies greatly depending on the amount of the non-volatile components such as the gelling agent and the surfactant in the gel-like portion and the specific gravity of the powder, it is necessary to appropriately adjust the amount according to each case. That is, the amount of the powder may be sufficient so that the non-volatile component such as the gelling agent functions as a binder for adhering the powder particles.

At this time, if the amount of powder to be compounded is small,
When the non-volatile component is filled between the powder particles, the gel portion does not become porous at the end of use, and the volatile component is not smoothly volatilized. However, in addition to the fact that the non-volatile component in the gel portion cannot function as a binder for adhering the powder particles, the powder falls off the gel portion and impairs the appearance of the fragrance, as described above. Care must be taken because the viscosity of the gel composition may increase, making uniform mixing difficult.

When the powder itself is made of a porous material, the powder itself has a liquid absorbing property, so that it is possible to further improve the liquid absorbing property of the entire gel portion. In addition, most of the volatile components in the second gel-like portion can be smoothly vaporized into the outside air.

Further, if a porous material having a deodorizing ability is used as a powder, not only does it have a function of sucking up volatile components of the second gel-like portion, but also it absorbs malodorous components in external air at the end of use. A deodorizing function can be added.
In other words, even in a situation where the amount of the fragrance component released from the second gel-like portion is reduced and the fragrance is weakened as compared to the first time, the atmosphere can be relaxed by effectively deodorizing the odor components in the external air. Can be maintained.

If the volatile active ingredient in the third gel portion is a deodorant and a porous material having deodorizing ability is used as a powder, the deodorant volatilizes in the air at the start of use. Provides a highly valuable gel-like aromatic deodorant that purifies air with the deodorizing function of the product and maintains the air-purified state by the function of adsorbing and deodorizing porous lump residue at the end of use. be able to.

Examples of the porous material having a deodorizing ability include a porous carrier such as zeolite, activated carbon, bentonite and pulp, a metal compound such as iron and copper, an acidic substance, a basic substance, citric acid, maleic acid, and the like. Known materials such as those supporting a reactive substance such as glyoxal can be used without particular limitation.

[0033]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are perspective views showing the gel-like fragrance according to the present invention. FIG. 1 shows the state of the gel-like fragrance before use, and FIG. 2 shows the state of the gel-like fragrance at the end of use. Shown respectively.

In FIG. 1, a gel-like fragrance 1 comprises a first gel-like part 2 and a second gel-like part 3, in which a porous powder 4 is uniformly dispersed. I have. Both gel-like parts 2, 3
Has a layered structure, with the second gel-like portion 3 on the lower side around a core material 6 erected at the center of the bottom of the synthetic resin container 5,
The first gel-like portion 2 is formed integrally with the upper layer side. Therefore, some of the volatile components in the second gel-like portion 3 volatilize directly from the side surface of the second gel-like portion 3, but most of the volatile components volatilize into the outside air via the first gel-like portion 2. I do.

The container 5 is composed of a lower lid member 7 in which the gel-like fragrance 1 is stored, and an upper lid member 8 capable of adjusting the amount of volatile components volatilized from the gel-like portion. The lower lid member 7
A cylindrical core member 6 stands from the center of the bottom surface. On the other hand, the upper lid member 8 has a main body 9 and an opening 10 at the top of the main body 9.
The top cover 11 is formed integrally with a columnar portion 12 protruding downward.

The columnar portion 12 of the upper lid member 8 is slidably fitted to the core material 6 of the lower lid member 7 so that positioning between them is possible, and the degree of exposure of the contained gel-like fragrance 1 is adjusted. By doing so, the intensity of the scent can be adjusted according to preference.

A screw groove is formed on the inner wall at the upper end of the lower lid member 7 and the outer wall at the lower end of the main body 9 (the screw groove is not shown) so that both can be screwed and connected. In order to prepare the gel-like fragrance 1, first, the liquid composition of the second gel-like portion 3 is placed in a container through the opening 10 at the top of the body 9 in a state where the lower lid member 7 and the body 9 are screwed together. Fill in 5. After the liquid composition has solidified, the liquid composition of the first gel-like portion 2 is further filled in the container 5, whereby a gel-like fragrance having a two-layer structure can be obtained.

The top lid 11 is fitted into the opening 10 of the main body 9 after the composition of the gel-like parts 2 and 3 is filled, and the container 5
By closing the inside, the volatile components are prevented from volatilizing before the start of use. As described above, the container 5 adjusts the scent when the gel fragrance 1 is used, and functions as a mold for the gel portions 2 and 3.

Immediately after the use of the gel-like fragrance 1 is started, mainly the volatile components contained in the first gel-like portion 2 are volatilized, and the fragrance drifts in the outside air. In the meantime, the first gel-like portion 2 gradually shrinks due to volatilization of the volatile component, but the second gel-like portion 3
From the first gel-like part 2
Since it moves to the outside and evaporates into the outside air, a certain level of scent can be maintained.

Further, as the volatile components evaporate from the first gel portion 2, as shown in FIG. 2, the non-volatile components and the powder 4 in the first gel portion 2 form a massive residue portion 13. Therefore, the volatile components contained in the second gel-like portion 3 are:
As in the prior art, the lump residue portion 1 is not trapped in the gel by the film formed by the outer gel portion.
Due to the liquid absorbing property of the liquid 2, the liquid is quickly sucked up to near the surface of the massive residue portion 13 and volatilizes therefrom into the external air.

FIG. 3 is a perspective view showing a second embodiment of the gel-like fragrance. This gel-like fragrance 1 includes a first gel-like portion 2 and a second gel-like portion 3 as in FIG. 1, such that the entire second gel-like portion 3 exists inside the first gel-like portion 2. Are formed integrally.

FIGS. 4 and 5 are perspective views showing the third embodiment. FIG. 4 shows a state of the gel-like fragrance before use, and FIG. 5 shows a state of the gel-like fragrance at the end of use. Are respectively shown. In FIG. 4, the gel-like fragrance 1 includes a first gel-like part 2, a second gel-like part 3, and a third gel-like part 14, and each gel-like part is formed in a layer shape. The third gel-like portion 1 as a lowermost layer around a core material 6 erected on the bottom surface of
The second gel-like portion 3 and the first gel-like portion 2 are sequentially laminated and fixed thereon. Third gel-like part 1
In No. 4, a deodorant is used as a volatile active ingredient, and powder 4 made of a porous material having a deodorizing ability is compounded only in the third gel portion 14.

That is, the gel fragrance 1 functions as a fragrance deodorant. At the start of use, the external air is cleaned by the deodorant volatilizing from the third gel portion 14 and In addition, an aroma component that volatilizes mainly from the first gel-like portion 2 can enjoy an aroma that is not mixed.

At the end of use when most of the volatile components contained in the third gel-like portion 13 and the first gel-like portion 2 are volatilized, the third gel-like portion 14 forms a massive residue portion 13.
Since the second gel-like portion 3 and the first gel-like portion 2 continue to contract, they gradually curve upward. Finally, as shown in FIG. 5, the first gel-like portion 2 that is being formed into a film adheres to the core material 6, and the shrinkage proceeds with that portion as a fulcrum. At this time, since the lump residue portion 13 has low adhesiveness to the bottom surfaces of the core member 6 and the lower lid member 7, the lower surface 15 is separated from the bottom surface of the container 5 and deforms into a bowl shape.

The deformation of the lump residue portion 13 into a bowl shape increases the volatilization area of volatile components such as fragrance components, thereby preventing a decrease in scent intensity, and at the same time, the powder 4 adsorbs malodorous components. Since the area to be treated also increases, effective deodorization becomes possible.

In each of Examples, different powders were blended into the third gel portion for each example, and the intensity of the fragrance was evaluated.

In actually producing the gel-like fragrance, 80 g, 20 and 40 g of the composition of the first gel-like part, the second gel-like part and the third gel-like part were used, respectively. The actual production of the gel-like aromatic deodorant was carried out by the following method.

A predetermined amount of a gelling agent (carrageenan and locust bean gum) is added to water at normal temperature, and the mixture is stirred with a homomixer, heated to 85 ° C. and left for 10 minutes, and the gel solution temperature is lowered to 70 ° C. On the other hand, the surfactant is melted by heating, and the fragrance component (lemon-based flavor) and the fragrance component retention agent are added to the gel composition in the form of a solution, and powder may be added as necessary. Fill the above container with stirring. After the filled gel-like part composition is solidified, the above operation is repeated to form a three-layer structure in which the third gel-like part, the second gel-like part, and the first gel-like part are laminated in this order from the lower layer side around the core material. A gel-like aromatic deodorant having a structure was obtained.

(Comparative Example) As shown in Table 1, no powder was added to the composition of the third gel-like portion, and thereafter, a gel-like aromatic deodorant was prepared in the same manner as in the above method. The difference in scent intensity between the gel-like aroma deodorant prepared in the example and the gel-like aroma deodorant was compared.

[0051]

[Table 1]

Each of the gelled aromatic deodorants prepared as described above was evaluated for its scent intensity by the absolute judgment method of the sensory test. The evaluation was based on the following five-step evaluation method. Table 2 shows the results.

As is apparent from the above description, according to the present invention, the first gel-like portion containing the fragrance component and the second gel-like portion containing the fragrance component at a higher concentration than the first gel-like portion. In the gel-like fragrance provided with, since powder was blended only in the first gel-like portion to form a porous lump residue at the end of use, the fragrance component in the second gel-like portion was quickly sucked up. As a result, the fragrance component can be volatilized smoothly in a state where the volatilization area is increased, and a certain level of fragrance can be maintained over a long period of time.

Further, in addition to the above constitution, a third gel-like part containing a volatile active ingredient is provided, and a second gel-like part is interposed between the first gel-like part and the third gel-like part having a layered structure. Even in a gel-like fragrance in which the entire gel-like part is integrally formed, a powder of at least one of the first gel-like part and the third gel-like part is mixed with a powder to provide a certain level of fragrance for a long period of time. It is possible to hold.

If the powder is blended only in the lowermost layer of the gel-like fragrance in which the gel-like part is laminated around the core material, even if the powder is slightly unevenly distributed in the lower part of the layer, the porous material is porous. The lower part of the lump residue part, which is a part, separates from the bottom of the container and comes into contact with the outside air. Can be provided.

If a porous material is used as the powder, it is possible to further improve the liquid absorbing property, and most of the volatile components in the second gel portion are smoothly volatilized into the outside air. be able to.
