Description

Specification

Gel-like aromatic deodorant

Technical field

The present invention relates to a gelled aromatic deodorant, which is a gelled aromatic deodorant capable of releasing an aromatic component and / or a deodorant component for a long period of time.

Kyoto technology

[0002] Conventionally, gelled aromatic deodorants have been frequently used from the viewpoint of safety and ease of handling. This gel-like aromatic deodorant usually comprises a gelling agent, water as a carrier, a medium such as a solvent, a surfactant, a composition of an aromatic component, etc., and after being heated and uniformly melted, Cooled and solidified.

[0003] However, in general, in a gelled aromatic deodorant, the gel shrinks with the volatilization of volatile components such as an aromatic component, a medium, and a deodorant component. As a whole, a hard layer or film composed of non-volatile components such as a gelling agent and a surfactant is formed.

[0004] Therefore, the gel-like aroma and deodorant have volatilization of volatile components due to the progress of gel shrinkage and film formation, even though a considerable amount of aroma components remain in the gel. Then, it became difficult, and finally the remaining fragrance component was confined in the gel as it was, causing a problem that a certain amount of fragrance component was not used effectively.

[0005] Therefore, a gel-like aroma deodorant intended to release an aroma component over a long period of time has been disclosed. (See Patent Documents 1 and 2)

Patent Document 1: JP-A-10-127743 (Paragraph 0008)

Patent Document 2: Japanese Patent Application Laid-Open No. 2000-70352 (Paragraph 0009)

[0008] The gel composition described in Japanese Patent Application Laid-Open No. H10-127743 has a gel portion containing a volatile active ingredient, a gel region having a different content coexisting in the gel portion, and a content of the volatile active ingredient. The higher the gel area, the volatile active ingredient is solubilized by the surfactant to form a gel, and when the gel part volatilizes and loses weight, the content of the volatile active ingredient between the gel areas The concentration of volatile active ingredients is high due to the The volatile active ingredient is supplied from the gel area to the lower gel area which comes into contact with the gel area, and the supplied volatile active ingredient also has a lower volatile active ingredient content. It is designed to volatilize together from the gel area.

[0009] Further, the gelled aromatic deodorant described in JP-A-2000-70352 contains a first gel-like portion containing an aromatic component, and a higher concentration of an aromatic component than the first gel-like portion. A second gel-like part comprising a second gel-like part and a third gel-like part containing a volatile active ingredient other than the fragrance component, and a second gel-like part between the first gel-like part and the third gel-like part having a layered structure. In the gelled aromatic deodorant integrally formed with the intervening parts, powder is blended into at least one of the first gel part and the third gel part, and the gel part blended with the powder is The configuration is such that a porous lump residue is formed at the end of use, so that the aroma component in the second gel-like portion smoothly evaporates through the porous portion of the lump residue.

Disclosure of the invention

Problems the invention is trying to solve

[0010] The present invention provides a gel-like aroma / deodorant capable of releasing an aroma component and / or a deodorant component over a long period of time while maintaining the strength and quality of the fragrance even more than the above technology. Aim.

Means for solving the problem

[0011] The present inventor has conducted further intensive studies focusing on the intensity and quality of the fragrance (such as freshness).

Accordingly, the present inventors have invented the present gel-like aroma deodorant capable of releasing an aroma component and / or a deodorant component over a long period of time while maintaining the intensity and quality of the aroma. In order to solve the above-mentioned problem, the invention according to claim 1 of the present invention provides a method in which a first gel layer and a second gel layer containing an aroma component and / or a deodorant component come into contact with each other at a part of the gel surface. The second gel layer is a gel-like aroma / deodorant having a non-contact portion coated with the first gel layer, and the first gel layer is more contractive than the second gel layer. An object of the present invention is to provide a gel-like aroma deodorant characterized in that the first gel layer is largely contracted so that the first gel layer contact portion of the second gel layer is exposed. In addition, the gel-like aromatic / deodorant is a gel-like substance having an aroma action and Z or a deodorant action.

[0012] As a mode of coating the first gel layer non-contact portion of the second gel layer, the first gel layer non-contact portion surface May be brought into contact with the covering member so as not to contact the outside air. Covering members include, but are not limited to, containers and other gel layers. By covering the non-contact portion of the first gel layer in this way, the entire surface of the second gel layer is in contact with the first gel layer or the covering member and does not come into contact with the outside air. (Fragrance components, medium, deodorant components, etc.) cannot be volatilized. On the other hand, when the first gel layer is brought into contact with the outside air, the volatile components can be volatilized, and the shrinkage of the first gel layer can be promoted.

[0013] The laminating direction of the first gel layer and the second gel layer may be any direction such as up and down, left and right, and oblique. When the first gel layer and the second gel layer are laminated in the up-down direction, if the upper layer is the first gel layer and the lower layer is the second gel layer as in the invention of claim 2, the first layer of the upper layer is formed. The gel layer is lightened by first releasing the volatile components and shrinking, but the weight of the second gel layer does not change until the contact portion of the first gel layer is exposed. Preferred from the viewpoint of gravity. Further, the upper layer may be a second gel layer, and the lower layer may be a first gel layer. In this case, when the first gel layer contracts, the gravity of the first gel layer itself is also applied, so that there is an advantage that separation from the second gel layer is enhanced. Further, a two-layer structure of the first gel layer and the second gel layer may be used, but if both are adjacent to each other, another layer may be laminated, or the first gel layer and the second gel layer may be alternately arranged. It may have a structure of three or more layers laminated on each other.

[0014] The first gel layer and the second gel layer each have a composite structure such as a multilayer structure as long as the contraction of the first gel layer is larger than that of the second gel layer as a whole. It does not matter. For example, the first gel layer may have a non-shrinkable portion (including a layer) in a part as long as it has a larger shrinkage than the second gel layer as a whole. In other words, even if there is a non-shrinkable part in the first gel layer, if the non-stretchable part shrinks as a whole due to the shrinkage of other shrinkable parts, the first gel layer and the (2) Force to separate from the gel layer.

[0015] According to the above configuration, immediately after the start of use, the first gel layer whose surface is exposed to the air starts volatilization of volatile components, causing a scent of a certain level or more to drift in the external air, and / Or exerts deodorant effect. At this time, as described above, since the entire second gel layer is in contact with the first gel layer and the covering member, volatilization of volatile components cannot be started. When the first gel layer shrinks due to the volatilization of the volatile component, the contact surface between the first gel layer and the second gel layer is reduced. The exfoliation exposes the first gel layer contact portion of the second gel layer. Only then can the second gel layer start volatilizing the volatile components. Therefore, the volatilization ability of volatile components in the first gel layer is reduced.In the middle stage of use, the second gel layer volatilizes volatile components in the late stage of use, so that the aromatic component and Z or deodorant component for a long period of time Can be volatilized, and the intensity and quality of the scent and the Z or deodorizing effect can be maintained.

[0016] As in the invention as set forth in claim 3, the gel of the first gel layer or the second gel layer is preferably produced under non-heated conditions, both the first gel layer and the second gel layer. Is more preferably produced under non-heating conditions. Non-heating here means that heating is not performed to such an extent as to cause denaturation and deterioration of the fragrance (or deodorant component). In other words, when manufactured under non-heating conditions, the fragrance (or deodorant component) does not undergo thermal denaturation or thermal degradation, and there is almost no volatilization. Therefore, unlike gels that require heating, volatile components are anticipated. This eliminates the need to combine excess fragrance (or deodorant components). Therefore, when the first gel layer contact portion of the second gel layer is exposed, a fresh fragrance immediately after the start of use is revived, and a high fragrance, high odor and deodorizing effect that can maintain a high fragrance until the late stage can be exerted. ).

Examples of gels that can be produced under non-heating conditions include aqueous gels such as hydroxyalkyl cellulose gels such as carboxymethyl cellulose gel, sodium alginate gel, and gels containing a water-absorbing resin. Examples thereof include, but are not limited to, aluminum octylate gel and the like, and these may be used alone or in combination. The aluminum octylate gel can be produced by mixing a mixture of aluminum octylate as a gel base material and isoparaffin as a solvent in advance, and a liquefied polyolefin as a crosslinking agent.

[0018] The material of the first gel layer is, for example, an aqueous gel or a gel mixed with a water-absorbing resin, as long as it is a shrinkable gel. Aqueous gel is a gelling agent that can be used as long as it is generally referred to as an aqueous gel. Hydroxanolequinoresenorelose, such as resenololose and hydroxypropinoresenololose, agar, amino acids such as guar gum, gum arabic, gelatin, pectin, starches, polyatolinoleamide, polyacrylic acid or amine salts thereof, alkali Salt, dilan gum, alginic acid Powers that can be exemplified by sodium salt, polyurethane, and the like are not limited to these. These gelling agents can be used alone or in combination. Examples of the water-absorbing resin include acrylic acid resins, cross-linked products of salts of alternating polymers of isobutylene and maleic anhydride, cross-linked products of starch / acrylate graft copolymers, but are not limited to these. It is not done. These water-absorbing resins can be used alone or in combination.

[0019] The material of the second gel layer is not limited as to the presence or absence of shrinkability as long as the material has less shrinkage than the first gel layer. Is preferred. Oily genole is a gelling agent that is generally referred to as an oily gel. Examples of the gelling agent include aluminum octylate (eg, aluminum 2-ethylhexanoate) and thermoplastic polyamide resin (eg, ESTER). — TERMINATEDO POLYAMIDES (ETPA), etc., 1, 2-hydroxystearic acid, 1,2-hydroxystearic acid metal stones, etc., silicon gel, limonene gel, higher fatty acid stones (eg, sodium stearate, etc.), dibenzylidene The ability to exemplify sorbitol and an amino acid-based gelling agent (for example, amide, ester, and amine salts of n-acylamino acid). These may be used alone or in combination.

[0020] The oil-based gel can contain a large amount of fragrance with a smaller volume and gel volume than the aqueous gel, so that even if the volume and the surface area are small, the oil-based gel can generate a strong fragrance. Therefore, compactness can be achieved, the selectivity of the design of the container and the like is improved, and it does not become bulky and does not become an obstacle during use. Further, since the oily gel hardly shrinks even when the aromatic component is volatilized, the surface area does not decrease, and the volatilization amount of the volatile component is almost constant and is suitable.

[0021] Furthermore, as in the invention according to claim 5, the oil-based gel preferably has translucency. By using a translucent gel, the design can be improved. Examples of the translucent oily gel include, but are not limited to, aluminum octylate and a thermoplastic polyamide resin.

[0022] Further, as in the invention according to claim 6, in the present gel-like aromatic deodorant, a support is erected on the bottom surface of a container having an upper surface opening filled with the second gel layer, and the support is provided. Then, the first gel layer is held. Although the form of the support is not particularly limited, for example, a rod-shaped support may be erected on the bottom of the container, and the first gel layer may be fixed therearound. First gel layer shrinks When the second gel layer shrinks along the support, the separation between the first gel layer and the second gel layer is enhanced, and the ability of the second gel layer to emit fragrance can be enhanced.

[0023] The shape of the support is not limited, but it is preferable that the first gel layer is formed into a rod body whose cross-sectional area decreases in a direction away from the second gel layer, that is, a substantially triangular pyramid shape. preferable. When formed in this manner, when the first gel layer contracts, it tends to contract in the direction away from the second gel layer, further increasing the separation property between the first gel layer and the second gel layer. is there.

[0024] Further, as in the invention according to claim 7, as a means for enhancing the releasability between the first gel layer and the second gel layer, a porous powder may be blended into the first gel layer. By mixing the first gel layer with the porous powder, the interface separation between the first gel layer and the second gel layer is likely to occur, and the first gel layer contact portion of the second gel layer is reliably exposed. Can be. The form in which the porous powder is blended into the first gel layer may be blended into the entire first gel layer, or may be blended only on the side of the first gel layer that is in contact with the second gel layer. Good. Further, the first gel layer may be formed into two layers, and the porous powder may be blended only in the layer on the contact side with the second gel layer. Examples of the porous powder include activated carbon, alumina, ceramic, florite, silica gel, porous calcium silicate, gypsum, and the like. The power is not limited to these.

[0025] On the other hand, as the fragrance and deodorant component that can be blended in the composition of the present invention, for example, as the fragrance, a wide range of natural and synthetic fragrances can be used. Examples of such fragrances include, for example, lemon oil, orange oil, bergamot oil, ylang-ylang oil, patili oil, citronella oil, lemongrass oil, boad rose oil, cinnamon oil, eucalyptus oil, cedar oil, sandalwood Oil, petitiva oil, geranium oil, peppermint oil, rose oil, jasmine oil and the like, and natural source plant essential oils such as limonene, geraniol, citronellol and linalool separated from these natural essential oils and their isolated flavors; Natural source animal flavors such as musk, civet, ambergris, castorium; vanillin, menthol, cinnamanololehide, heliotopin, linalool, geraniol, citronellol, citral, menthol, minoresen, minoresenorore, anis Aldehyde, Cineau Synthetic fragrances such as, ionicon, pinene, limonene, camphene, cis-3-hexenol, benzyl alcohol, hyaminolecinamic alcohol, eugenol, linalolinoleacetate, benzyl acetate; at least two of these various essential oils or fragrances Blended fragrance And various fragrance ingredients. As a solvent for the fragrance, for example, dipropylene glycol, propylene glycol, benzyl benzoate, 3-methinole-3-methoxy-1-butanol, isoparaffin, normal paraffin and the like can be used.

[0026] In addition, as far as it does not hinder the present invention, and if necessary, surfactants (emulsifiers, solubilizers, etc.), ultraviolet absorbers, pH adjusters, preservatives and bactericides (ortho-phenylonol , Benzoic acid, salicylic acid, isopropylmethylphenol, etc.), antibacterial agents, insect repellents (paradichlorobenzene, naphthalene, camphor, etc.), attractants (acetoxyphenylbutanone, methyleugenol, etc.), repellents, pigments, salts And a crosslinking agent.

The invention's effect

[0027] In the gelled aromatic deodorant according to the present invention, immediately after the start of use, the first gel layer whose surface is exposed to the air starts volatilization of volatile components, and thereafter, the first gel layer Only when the contact area of the first gel layer is exposed due to volatilization shrinkage will the second gel layer start volatilizing volatile components, so that the aroma volatilization ability of the first gel layer will decrease. Also, high fragrance volatilization is possible while maintaining the intensity and quality of the fragrance.

[0028] Further, since the first gel layer and the Z or second gel layer are manufactured under non-heating conditions, it is possible to incorporate a large amount of a fresh fragrance component that does not cause thermal deterioration of the fragrance. It becomes. Therefore, when the first gel layer contact portion of the second gel layer is exposed, the freshly opened fragrance is revived, so that high fragrance can be maintained until late.

[0029] Further, since the second gel layer uses an oily gel, a large amount of fragrance can be contained with a small gel volume, and the oily gel hardly shrinks even if the fragrance is volatilized. Therefore, the surface area is not reduced, and the amount of fragrance volatilized is almost constant and suitable.

[0030] In addition, the consumption state is difficult to understand because the oily gel alone hardly shrinks. However, when the oily gel is combined with the highly contractible first gel layer, the contraction state of the first gel layer can be observed. In addition, there is an effect that it is easy to determine the consumption state of the oily gel.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is an exploded perspective view of the present gelled aromatic deodorant, and Fig. 2 is an enlarged view of the first gel layer, the second gel layer, the main part of the housing part and the support. A perspective view, FIG. 3 is an exploded perspective view of the present gelled aromatic deodorant in a later stage of use, and FIG. 4 is a cross-sectional view of the present gelled aromatic deodorant. As shown in Fig. 1 and Fig. 3, the present gel-like fragrance deodorant permeates a two-layered gel formed integrally with the first gel layer 1 as the upper layer and the second gel layer 2 as the lower layer. It is housed in the container 3 for use. Specifically, the present gel-like aroma deodorant is obtained by filling the second gel layer 2 into a housing portion 4a of a lower lid member 4 described below, and fixing the first gel layer 1 around a support 4b described later. It is formed by covering with the upper lid member 5. The first gel layer non-contact portion 2b of the second gel layer 2 is in contact with the inner wall surface of the housing portion 4a, and the housing portion 4a functions as a covering member. Therefore, since the entire surface of the second gel layer 2 is in contact with the first gel layer 1 or the inner wall of the housing portion 4a, volatilization of volatile components cannot be started.

[0032] The first gel layer 1 is made of an aqueous gel and is divided into an aromatic layer la containing an aromatic component and a deodorant layer lb containing a deodorant component. For the second gel layer 2, an oil-based gel is used. The first gel layer 1 and the second gel layer 2 are preferably manufactured under non-heating conditions. Further, the first gel layer 1 and the second gel layer 2 contain an aromatic component and / or a deodorant component, but may contain other substances such as an antibacterial composition.

As shown in FIG. 1 and FIG. 4, the fragrance container 3 is made of a synthetic resin, and has a container-like lower lid member 4 in which a gel is placed, and the lower lid member 4 is sealed and has an arbitrary size. And an umbrella-shaped upper lid member 5 that can be opened only. The lower lid member 4 is formed integrally with a dish-shaped receiving portion 4a for filling the second gel layer 2 therein, and a screw groove (not shown) is formed at the upper end of the outer wall surface of the receiving portion 4a. The upper cover member 5 can be connected to and connected to a screw groove (not shown) formed at the lower end of the inner wall of the upper cover member 5. In addition, a cylindrical support 4b is erected from the center of the bottom surface of the storage portion 4a of the lower lid member 4.

The upper lid member 5 is composed of a main body 5a and a top lid 5c fitted into a top opening 5b of the main body 5a. The top lid 5c has a columnar portion 5d extending downward from the center of the inner surface thereof. The body is protrudingly formed. The columnar portion 5d is slidably fitted in the support 4b of the lower lid member 4, whereby positioning between the lower lid member 4 and the upper lid member 5 is enabled. By adjusting the position between the two members 4 and 5, the amount of volatilization is adjusted so that the strength of the scent and / or the deodorizing effect can be obtained as desired.

In order to produce a gel-like aroma deodorant, first, the accommodating portion 4a of the lower lid member 4 and the upper lid member 5 The liquid composition of the second gel layer 2 is filled into the fragrance container 3 from the top opening 5b of the upper lid member 5 in a state where the main body portion 5a is joined. At this time, the filling amount of the liquid composition in the second gel layer 2 is set to be equal to or less than the upper end of the storage portion 4a of the lower lid member 4. After the second gel layer 2 has solidified, the liquid composition of the first gel layer 1 is further filled and solidified to a predetermined position in the fragrance container 3, and the top lid 5c is inserted into the top opening 5b of the main body 5a. By being inserted, the present gel-like aroma deodorant is formed. By closing the inside of the fragrance container 3 in this manner, the volatile components can be prevented from volatilizing before the use is started.

[0036] According to the gelled aromatic deodorant having the above-described configuration, the positions of the upper lid member 5 and the lower lid member 4 are separated from each other to release the hermetically sealed state. Volatilization of volatile components is started, causing scent to drift into the outside air and deodorizing effect. On the other hand, the upper surface of the second gel layer 2, that is, the first gel layer contact portion 2a contacts the first gel layer 1, and the first gel layer non-contact portion 2b contacts the inner wall surface of the housing portion 4a of the lower lid member 4. Therefore, it is in a sealed state, and the volatilization of volatile components has not started.

[0037] Then, as shown in FIG. 3, the first gel layer 1 gradually shrinks due to volatilization of the volatile component. As a result, the contact surface between the first gel layer 1 and the second gel layer 2 separates, Since the first gel layer contact portion 2a of the second gel layer 2 is exposed, the second gel layer 2 starts volatilizing volatile components. Therefore, it is possible to maintain a certain level of release of fragrance and / or deodorant components until the later stage of use of the gel-like aroma / deodorant.

[0038] Further, since an oily gel is used for the second gel layer 2, a large amount of fragrance can be contained with a small gel volume, and the oily gel hardly shrinks even if the fragrance is volatilized. Therefore, the surface area is not reduced, and the amount of fragrance volatilized is almost constant and suitable. Furthermore, since the oil-based gel is manufactured under non-heated conditions, it is possible to incorporate a large amount of a fresh fragrance component that does not cause thermal deterioration of the fragrance. Therefore, when the first gel layer contact portion 2a of the second gel layer 2 is exposed, the freshly opened fragrance is revived, so that high level and fragrance can be maintained until the later stage of use.
