Description

Fragrant gel deodorant

Technical Field

The present invention relates to a gel-like deodorant, which is capable of releasing a fragrance component and/or a deodorant component for a long period of time.

Background

Conventionally, gel-like deodorant fragrances have been used in many cases from the viewpoints of safety and ease of handling. The gel-like deodorant is generally a composition comprising a gelling agent, a medium such as water or a solvent as a carrier, a surfactant, an aromatic component, etc., and is heated to be uniformly melted, and then cooled and solidified.

However, in general, in a gel-like deodorant, a gel shrinks with volatilization of volatile components such as an aromatic component, a mediator, and a deodorant component, and a hard coat composed of a non-volatile component such as a gelling agent and a surfactant is formed on the surface or the whole of the gel at a later stage of use.

Therefore, the gel-like deodorant has a problem that not only the fragrance component remains in a considerable amount in the gel, but also the volatile component is gradually difficult to volatilize due to the shrinkage of the gel and the progress of film formation, and finally, the remaining fragrance component is confined in the gel as it is, so that a considerable amount of fragrance component cannot be effectively used.

Therefore, a gel-like deodorant for fragrance emission over a long period of time is disclosed (see patent documents 1 and 2).

Patent document 1: japanese patent laid-open publication No. 10-127743 (paragraph 0008)

Patent document 2: japanese patent laid-open No. 2000-70352 (paragraph 0009)

In the gel composition described in jp-a-10-127743, gel-like regions having different contents coexist in a gel-like portion containing a volatile active ingredient, and a gel-like region having a high content of the volatile active ingredient is dissolved by a surfactant to be in a gel-like state, and when the gel-like portion is volatilized or reduced, a concentration gradient is generated due to a difference in the content of the volatile active ingredient between the gel-like regions, and the volatile active ingredient is supplied from the gel-like region having a high content of the volatile active ingredient to the gel-like region having a low content of the volatile active ingredient in contact therewith, and the supplied volatile active ingredient is also volatilized from the gel-like region having a low content of the volatile active ingredient.

Further, in a gel-like deodorant described in japanese patent application laid-open No. 2000-70352, which comprises a first gel-like portion containing an aromatic component, a second gel-like portion containing an aromatic component at a higher concentration than the first gel-like portion, and a third gel-like portion containing a volatile active component other than the aromatic component, in the gel-like deodorant formed integrally by interposing the second gel-like portion between the first gel-like portion and the third gel-like portion having a layered structure, powder is incorporated into at least 1 of the first gel-like portion or the third gel-like portion, and the gel-like portion incorporating the powder is formed into a porous block-like residue portion at the end of use, so that the aromatic component in the second gel-like portion smoothly volatilizes through the porous portion of the block-like residue portion.

Disclosure of Invention

The present invention aims to provide a gel-like deodorant capable of releasing a fragrance component and/or a deodorant component for a long period of time while maintaining the strength and quality of fragrance as compared with the above-mentioned techniques.

The present inventors have paid attention to the intensity and quality (freshness and the like) of fragrance and have further studied until the present invention has invented a gel-like deodorant capable of releasing a fragrance component and/or a deodorizing component for a long time while maintaining the intensity and quality of fragrance. In order to solve the above-mentioned problems, according to a first aspect of the present invention, there is provided a gel-like deodorant, comprising a first gel layer containing an aromatic component and/or a deodorant component and a second gel layer in contact with each other at a part of the gel surface, wherein a non-contact portion between the second gel layer and the first gel layer is covered, wherein the first gel layer has a larger contractility than the second gel layer, and a contact portion between the second gel layer and the first gel layer is exposed by contraction of the first gel layer. The gel-like deodorant is a gel-like substance having an aromatic action and/or a deodorizing action.

In the form of covering the non-contact portion of the second gel layer with the first gel layer, the surface of the non-contact portion of the first gel layer may be brought into contact with the covering member so as not to come into contact with the outside air. Examples of the covering member include, but are not limited to, a container and other gel layers. By covering the non-contact portion of the first gel layer in this manner, the entire surface of the second gel layer is in contact with the first gel layer or the covering member and is not in contact with the outside air, and therefore, the volatile components (fragrance component, medium, deodorant component, and the like) cannot be volatilized by the second gel layer. In another aspect. The first gel layer can volatilize volatile components by contacting with the outside air, and can promote the first gel layer to shrink.

The stacking direction of the first gel layer and the second gel layer may be vertical, horizontal, or inclined, and the arrangement relationship between the two layers is not limited. When the first gel layer and the second gel layer are stacked in the vertical direction, if the upper layer is the first gel layer and the lower layer is the second gel layer as in the invention described in the second aspect, the first gel layer in the upper layer releases the volatile component first and becomes lighter by shrinkage, but the second gel layer does not change its weight until the first gel layer contact portion is exposed, and therefore, it is preferable from the viewpoint of gravity to support the first gel layer. Alternatively, the upper layer may be the second gel layer and the lower layer may be the first gel layer. In this case, when the first gel layer shrinks, the gravity of the first gel layer itself is also added, and therefore, there is an advantage that the first gel layer is highly separable from the second gel layer. Further, the gel sheet may have a 2-layer structure of the first gel layer and the second gel layer, but if the two layers are adjacent to each other, another layer may be stacked, or 3 or more layers of the first gel layer and the second gel layer may be alternately stacked.

In addition, if the first gel layer and the second gel layer as a whole have a larger shrinkage relation than the second gel layer, the inside thereof may have a composite structure such as a multilayer structure. For example, the first gel layer may have a larger shrinkage property as a whole than the second gel layer, and a part thereof may have a non-shrinkable part (including layer). That is, even if there is a non-contractible portion in a part of the first gel layer, the non-contractible portion is contracted by another portion having contractibility, and if the first gel layer and the second gel layer are contracted as a whole, the first gel layer and the second gel layer can be separated.

With the above configuration, the first gel layer exposed to the air immediately after the use starts volatilizes volatile components, and the fragrance floats in the outside air at a certain level or more, and/or the deodorizing effect is exhibited. At this time, as described above, the second gel layer is entirely in contact with the first gel layer and the covering member, and thus volatile components cannot start to be volatilized. Then, when the first gel layer is volatilized and contracted by the volatile component, the contact surface between the first gel layer and the second gel layer is peeled off, and the contact portion between the second gel layer and the first gel layer is exposed. At this point, the second gel layer may begin to volatilize volatile components for the first time. Therefore, the volatile component is volatilized by the second gel layer from the middle stage of use to the later stage of use in which the volatile component volatilization ability of the first gel layer is reduced, so that the fragrance component and/or the deodorant component can be volatilized for a long period of time, and the intensity of the fragrance and the quality of the fragrance and/or the deodorant effect can be maintained.

As in the invention according to the third aspect, the gel of the first gel layer or the second gel layer is preferably produced under non-heating conditions, and more preferably, both the first gel layer and the second gel layer are produced under non-heating conditions. The term "non-heated" as used herein means heating to such an extent that the flavor (or deodorizing component) is not denatured and deteriorated. That is, if the gel is produced under non-heating conditions, since there is little volatilization of the perfume (or deodorizing component) due to no thermal denaturation or thermal deterioration, it is not necessary to add an excessive amount of perfume (or deodorizing component) in anticipation of the volatile component, unlike the case of a gel that must be heated. Therefore, when the contact portion of the second gel layer with the first gel layer is exposed, the fresh flavor used immediately before the start is volatilized, and high aromaticity can be continued to the later stage (in addition, high deodorizing effect can be exhibited).

Examples of the gel that can be produced without heating include aqueous gels (hydroxyalkyl cellulose gels such as carboxymethyl cellulose, sodium alginate gels, and the like), and gels containing a water-absorbent resin, and examples of the oily gel include, but are not limited to, aluminum caprylate gels. The aluminum octoate gel may be produced by mixing a mixture of aluminum octoate as a gel base and isoparaffin as a solvent with liquefied polyolefin as a crosslinking agent in advance.

The material of the first gel layer may be a gel having a contractile property, and examples thereof include, but are not limited to, aqueous gels and gels containing a water-absorbent resin. The aqueous gel may be a gel generally called an aqueous gel, and examples of the gelling agent include, but are not limited to, hydroxyalkylcelluloses such as carrageenan, locust bean gum, polyvinyl alcohol, carboxymethylcellulose, hydroxymethylcellulose and hydroxypropylcellulose, amino acids such as agar, gum guaiac, gum arabic and gelatin, pectins, starches, polyacrylamides, polyacrylic acid or an amine salt or alkali metal salt thereof, gellan gum, sodium alginate and polyurethane. These gelling agents may be used alone or in combination of 1. Examples of the absorbent resin include, but are not limited to, acrylic resins, crosslinked salts of alternating polymers of isobutylene and anhydrous maleic acid, and crosslinked starch/acrylate graft copolymers. These water-absorbent resins may be used singly or in combination of 1 kind.

The material of the second gel layer may have a smaller shrinkability than the first gel layer, and is not limited to the non-shrinkability. The oily gel may be generally referred to as an oily gel, and examples of the gelling agent include, but are not limited to, aluminum octylate (e.g., aluminum 2-ethylhexanoate), thermoplastic polyamide resins (e.g., ESTER-terminato polymers (ETPA)), 1, 2-hydroxystearic acid, metal soaps of 1, 2-hydroxystearic acid, silicone gel, limonene gel, higher fatty acid soaps (e.g., sodium stearate), dibenzylidene sorbitol, and amino acid gelling agents (e.g., amides, ESTERs, and amine salts of n-acylamino acids). In addition, these may be used alone or in plural.

The oil-based gel can contain a large amount of perfume with a smaller gel volume than the aqueous gel, and therefore can sufficiently generate a fragrance even when the volume and the surface area are small. Therefore, the container can be miniaturized, the design selectivity of the container is improved, and the container is not expanded and troublesome in use. Further, the oily gel hardly shrinks even when the aromatic component is volatilized, so that the surface area is not reduced, and the amount of volatilization of the volatile component is preferably almost constant.

Further, as in the fifth aspect of the invention, the oil-based gel preferably has light transmittance. By forming the gel to be light-transmitting, the design can be improved. Examples of the light-transmitting oily gel include, but are not limited to, aluminum octylate and thermoplastic polyamide resin.

In addition, according to the invention described in the sixth aspect, the gel-like deodorant is provided with a support body on the bottom surface of the container in which the upper surface of the second gel layer is opened, and the first gel layer is held by the support body. The form of the support is not particularly limited, and for example, a rod-shaped support is set on the bottom surface of the container, and the first gel layer may be fixed to the periphery thereof. Since the first gel layer shrinks along the support when the first gel layer shrinks, the separability between the first gel layer and the second gel layer is improved, and the fragrance volatilization ability of the second gel layer can be improved.

The shape of the support is not limited, but it is preferable that the first gel layer is formed into a rod having a smaller cross-sectional area in a direction away from the second gel layer, that is, into a substantially triangular pyramid shape. This is because, if formed in this way, the first gel layer tends to contract in the direction of separation from the second gel layer when contracting, and the separability between the first gel layer and the second gel layer is further improved.

As a method of improving the separability between the first gel layer and the second gel layer as in the seventh aspect of the present invention, porous powder may be mixed in the first gel layer. By blending the porous powder in the first gel layer, interfacial separation between the first gel layer and the second gel layer is easily caused, and the contact portion of the second gel layer with the first gel layer can be reliably exposed. In the form in which the porous powder is incorporated in the first gel layer, the porous powder may be incorporated in the entire first gel layer, or may be incorporated only in the side of the first gel layer that is in contact with the second gel layer. The first gel layer may be 2 layers, and the porous powder may be mixed only in the layer on the side contacting the second gel layer. Examples of the porous powder include, but are not limited to, activated carbon, alumina, ceramics, red kaolin, silica gel, porous calcium silicate, and gypsum.

On the other hand, as the aroma and deodorizing component which can be blended in the composition of the present invention, for example, as the aroma, a wide range of natural and synthetic aromas can be used. Examples of such fragrances include natural plant-derived essential oils such as lemon oil, orange oil, bergamot oil, ylang-ylang oil, patchouli oil, citronella oil, lemongrass oil, rosewood oil, clove oil, eucalyptus oil, cedar wood oil, sandalwood oil, vetiver oil, geranium oil, peppermint oil, rose oil, and jasmine oil, and limonene, geraniol, rhodinol, and linalool isolated from these natural essential oils; moschus, Zibethum, ambergris, and nutria derived from natural animal perfume; synthetic perfumes such as vanillin, menthol, cinnamaldehyde, piperonal, linalool, geraniol, rhodinol, citral, menthol, myrcene, geraniol, anisaldehyde, eucalyptol, ionone, pinene, limonene, camphene, cis-3-hexenol, benzyl alcohol, alpha-amyl cinnamic alcohol, eugenol, linalyl acetate (linalyl acetate), benzyl acetate, and the like; at least 2 kinds of compound perfumes of these various essential oils and perfumes are blended. Examples of the solvent for the perfume include dipropylene glycol, propylene glycol, benzyl benzoate, 3-methyl-3-methoxy-1-butanol, isoparaffin, and n-paraffin.

In addition, as needed, surfactants (emulsifiers, solubilizers, etc.), ultraviolet absorbers, pH adjusters, antiseptics and bactericides (o-phenylphenol, benzoic acid, salicylic acid, isopropyl cresol, etc.), antibacterial agents, insect repellents (p-dichlorobenzene, naphthalene, camphor, etc.), attractants (acetoxyphenyl butanone, methyl eugenol, etc.), repellents, pigments, salts, crosslinking agents, and the like may be added within the range not interfering with the present invention.

In the gel-like deodorant according to the present invention, the first gel layer whose surface is exposed to the air starts volatilizing volatile components immediately after the start of use, and thereafter the second gel layer starts volatilizing volatile components for the first time as the first gel layer is volatilized and contracted to be exposed from the first gel layer contact portion, so that the fragrance can be highly volatilized while maintaining the strength and quality of the fragrance even in the middle stage to the later stage of use in which the fragrance volatilizing ability of the first gel layer is reduced.

Further, since the first gel layer and/or the second gel layer are produced under non-heating conditions, there is no thermal deterioration of the perfume, and a large amount of perfume components having a fresh feeling can be combined. Therefore, when the contact portion of the second gel layer with the first gel layer is exposed, the opened fresh fragrance is volatilized, and therefore, high fragrance can be continued until a later stage.

Further, since the oil-based gel is used in the second gel layer, a large amount of the fragrance can be contained with a small gel volume, and since the oil-based gel hardly shrinks even when the fragrance is volatilized, the fragrance volatilization amount is preferably almost constant without reducing the surface area.

Further, since only the oil gel hardly shrinks, the state of consumption is difficult to judge, but if the oil gel and the first gel layer having high contractility are combined, there is an effect that the state of consumption of the oil gel can be easily judged by observing the state of shrinkage of the first gel layer.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is an exploded perspective view of the gel-like deodorant, fig. 2 is an enlarged perspective view of a main part of a first gel layer, a second gel layer, a storage section, and a support, and fig. 3 is an exploded perspective view of the gel-like deodorant at a later stage of use. FIG. 4 is a sectional view of the gel-like deodorant. As shown in fig. 1 to 3, the gel-like deodorant is formed by containing a 2-layer gel in a fragrance container 3, the gel having a 2-layer structure integrally formed with a first gel layer 1 as an upper layer and a second gel layer 2 as a lower layer. Specifically, the gel-like deodorant is formed by filling a second gel layer 2 in a housing portion 4a of a lower cover member 4 described later, fixing a first gel layer 1 around a support body 4b described later, and covering the same with an upper cover member 5. The non-contact portion 2b of the second gel layer 2 with the first gel layer comes into contact with the inner wall surface of the housing portion 4a, and the housing portion 4a functions as a covering member. Therefore, the second gel layer 2 is in contact with the first gel layer 1 or the inner wall of the housing 4a over the entire surface thereof, and therefore, the volatile component cannot start to be volatilized.

The first gel layer 1 is divided into an aromatic layer 1a containing an aromatic component and a deodorant layer 1b containing a deodorant component by using an aqueous gel. The second gel layer 2 used was an oily gel. The first gel layer 1 and the second gel layer 2 are preferably manufactured in a non-heated condition. The first gel layer 1 and the second gel layer 2 contain an aromatic component and/or a deodorant component, and may contain other substances such as an antibacterial composition.

As shown in fig. 1 to 4, the fragrance container 3 is made of synthetic resin, and is composed of a container-shaped lower lid member 4 on which a gel is placed, an umbrella-shaped upper lid member 5 which seals the lower lid member 4 and can be opened only by an arbitrary width. A dish-shaped storage part 4a for filling the second gel layer 2 therein is integrally formed on the lower cover member 4, and a screw thread is formed on the upper end of the outer wall surface of the storage part 4a

(not shown) is screwed into a screw (not shown) formed at the lower end of the inner wall of the upper lid member 5 so as to be connectable thereto. In addition, a cylindrical support 4b is provided in the housing portion 4a of the lower cover member 4 from the center of the bottom surface thereof.

The upper lid member 5 is composed of a body portion 5a and a lid portion 5c fitted into a top opening 5b of the body portion 5a, and a columnar portion 5d is integrally formed on the lid portion 5c so as to protrude downward from the center of the inner surface thereof. The columnar portion 5d is slidably fitted in the support body 4b of the lower cover member 4, and thereby the position between the lower cover member 4 and the upper cover member 5 can be determined. By adjusting the position between the two members 4, 5 to adjust the amount of evaporation, the intensity of fragrance and/or deodorizing effect according to preference can be obtained.

When the gel-like deodorant is produced, first, the liquid composition of the second gel layer 2 is filled in the fragrance container 3 from the top opening 5b of the upper lid member 5 in a state where the containing portion 4a of the lower lid member 4 and the body portion 5a of the upper lid member 5 are screwed together. At this time, the filling amount of the liquid composition in the second gel layer 2 is not more than the upper end of the housing portion 4a of the lower cover member 4. After the second gel layer 2 is solidified, the liquid composition of the first gel layer 1 is filled and solidified to a predetermined position in the fragrance container 3, and the top cover portion 5c is fitted into the top opening 5b of the main body portion 5a, thereby forming the gel-like fragrance deodorant. Thus, the fragrance container 3 is locked, and volatilization of volatile components before use can be prevented.

When the gel-like deodorant is used, the sealing state between the upper lid member 5 and the lower lid member 4 is released by separating the two members, and the volatile component in the first gel layer 1 begins to volatilize, so that the fragrance floats in the outside air, and the deodorant effect is exerted. On the other hand, the second gel layer 2 has an upper surface, i.e., the first gel layer contact portion 2a, in contact with the first gel layer 1, and the first gel layer non-contact portion 2b is in contact with the inner wall surface of the housing portion 4a of the lower cover member 4, so that a sealed state is achieved and volatilization of volatile components does not start.

Then, as shown in fig. 3, the first gel layer 1 gradually shrinks due to the volatilization of the volatile component, whereby the contact surface between the first gel layer 1 and the second gel layer 2 is separated, and the contact portion 2a of the second gel layer 2 with the first gel layer is exposed, so that the volatilization of the volatile component of the second gel layer 2 starts. Therefore, the gel-like deodorant can keep the release of the fragrance and/or deodorant component at a level or more from the beginning of use to the later stage of use.

Further, since the oil-based gel is used in the second gel layer 2, a large amount of the fragrance can be contained with a small gel volume, and since the oil-based gel hardly shrinks even when the fragrance is volatilized, the surface area is not reduced, and the amount of fragrance volatilized is almost constant, which is preferable. Further, since the oil-based gel is produced under non-heating conditions, there is no thermal deterioration of the fragrance, and a large amount of fragrance components having a fresh feeling can be combined. Therefore, when the contact portion 2a of the second gel layer 2 with the first gel layer is exposed, the fresh fragrance that has been turned on is volatilized, and therefore, high aromaticity can be continued until the later stage of use.

Examples

The present invention will be described in more detail with reference to examples. First, a gel used in the gel-like deodorant will be described. In the gel-like deodorant, carrageenan is used as the aqueous gel of the aromatic layer 1a of the first gel layer 1, a gel containing an aromatic component (hereinafter referred to as "aromatic carrageenan gel") is used as the base material, carrageenan is used as the aqueous gel of the deodorant layer 1b, a gel containing a deodorant component (hereinafter referred to as "deodorant carrageenan gel") is used as the base material, and an oil-based gel is used as the second gel layer 2. Table 1 shows the amounts of raw materials for fragrant carrageenan gel, Table 2 shows the amounts of raw materials for deodorant carrageenan gel, and Table 3 shows the amounts of raw materials for oil gel in this example. In addition, Table 4 shows the raw material blending amounts of the aromatic carrageenan gels in the comparative examples.

Aromatic Carrageenan gel (control)

The procedure for preparing the above-mentioned gel is described below.

Aromatic carrageenan gels (examples and controls): adding base material and dispersing medium into the initial water, stirring, heating to 85 deg.C, standing for 10 min, and cooling to 60 deg.C with the rest water. On the other hand, the surfactant was dissolved when heated to about 40 ℃, and the gel composition in the solution state was added in a state where the fragrance was attached after returning to room temperature.

Deodorizing carrageenan gel: adding base material and dispersing medium into the initial water, stirring, heating to 85 deg.C, standing for 10 min, and cooling to 60 deg.C with the rest water. A deodorant is added to the solution-like gel composition.

Oily gel: the mixture of the adhering perfume, the transparentizing agent and the crosslinking agent is used as the solution A, the mixture of the mixed solvent and the base material is used as the solution B, and the solution A and the solution B are mixed. All of these reactions are carried out at a temperature of 5 to 35 ℃ or lower, preferably 5 to 15 ℃.

As shown in table 5, the gel-like deodorant of the present example was prepared by using the solution-like gel prepared as described above as an oily gel in the lower second gel layer 2, as a deodorizing carrageenan gel in the deodorizing layer 1b of the upper first gel layer 1, and as a fragrant carrageenan gel in the fragrance layer 1a, and filling the fragrance container 3 with the amounts shown in the table to use a cured product. The comparative example used a deodorizing carrageenan gel for the deodorizing layer 1b of the first gel layer 1, and a fragrant carrageenan gel for the fragrant layer 1a (comparative example). In the example, the second gel layer 2, the deodorant layer 1b of the first gel layer 1, and the aromatic layer 1a of the first gel layer 1 were stacked in this order, and in the comparative example, the deodorant layer 1b of the first gel layer 1 and the aromatic layer 1a of the first gel layer 1 were stacked in this order.

TABLE 5

Evaluation of the intensity of fragrance and preference and comprehensive evaluation thereof were carried out by 7 panelists (5 men and 2 women) in the initial stage of use (immediately after the start of use), the middle stage of use (15 days after the start of use), and the late stage of use (30 days after the start of use) of each of the gel-like aromatic deodorants prepared in the above-described manner, according to the absolute judgment method of sensory examination. Table 6 shows evaluation of flavor intensity, table 7 shows evaluation of flavor palatability, and table 8 shows overall evaluation of these. Further, the evaluation of flavor palatability is an evaluation of flavor quality, and the overall evaluation is an overall evaluation of a gel-like aromatic deodorant combining flavor intensity and palatability. In addition, 7 panelists all had normal smell and had experience in developing fragrance deodorant business for 2 years or more.

The functionality test method is described. First, the air in a stainless functional box having a volume of 1000L is ventilated until no odor is perceived (usually 20 to 30 minutes), and then a gel-like deodorant is placed in the functional box. Then, after leaving at room temperature (about 25 ℃ C.) for 20 minutes, the fragrance intensity, preference and overall evaluation were judged by putting the nose close to the small window on the front side of the box, and the results were averaged for 7 persons. The respective determinations (scores) are made based on the criteria recorded in the respective tables.
