Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is directed to a shaver for removing skin odors, especially sweat odors, body odors, or unusual odors generated from cells adhering to a shaver, and reducing the corrosion of spray cans. It relates to a spray deodorant.

[0002]

2. Description of the Related Art In general, foul odors and odors originate from smoke and waste liquid in factories, cigarettes and human waste, kitchen garbage, and the like, and their types are also diverse. At home, odors from toilets, kitchens, pets, cigarettes and the like cause discomfort, irritation, headaches and the like. In particular, when the air conditioner is operated, the air conditioner is often kept in a closed room.

Conventionally, methods for eliminating such malodors and off-flavors are roughly classified into the following methods. Sensory deodorant method: A method of concealing bad smells and unpleasant odors by the odor emitted by aromatic substances (such as fragrance essential oils) and making them difficult to feel. Physical deodorization method: A method of diluting and removing malodors by ventilation and diffusion, adsorbing odors using silica gel or activated carbon, or including an odorant with an inclusion compound such as cyclodextrin.

[0004] Chemical deodorization method: A method of chemically reacting (neutralizing, adding, condensing, oxidizing, etc.) with a malodorous or off-flavor component to deodorize it. For example, an open flame combustion method or an oxidation method using an oxidizing agent such as ozone or potassium permanganate. Biological deodorization: kills microorganisms that cause spoilage,
A method to prevent rot and prevent the generation of bad smell.

[0005] The above-mentioned sensory deodorization method is a method mainly used in ordinary households. However, aromatic substances have a limited ability to remove odorous substances, and are used when odor and malodor are mixed. There is a disadvantage that it is difficult to balance odor and odor. In addition, since the scent has a preference of a person and may cause disgust in some cases, application to a shaver is difficult.

The above-mentioned physical deodorization method has been widely used since ancient times. However, there are problems in terms of equipment, the point that odorous substances are desorbed due to a temperature change in an adsorbent, and the point of maintenance. is there. The above-mentioned chemical deodorization method,
It is difficult to select a substance that effectively reacts to a variety of odorous substances in malodor, and it is not practical in terms of the safety of chemicals used and the possibility that the shaver constituent members may deteriorate.

[0007] The biological deodorizing method is not suitable for removing the odor of the atmosphere, and has drawbacks such as the necessity of a device and a long time for developing the deodorizing effect. As described above, there are advantages and disadvantages in applying the conventional deodorizing method to the deodorization of a shaver (see “Industrial Research Committee,“ New Deodorizing Technology ”, Susumu Kokubu (1981)). Therefore, some of the inventors have tried to use an extract obtained from a plant as an active ingredient of a deodorant, and as a result, a deodorant containing a deodorant active ingredient obtained from a plant as a main component. The agent has been developed and a patent application has already been filed (see Japanese Patent Application Laid-Open No. 1-218456).

[0008] The deodorant active ingredient obtained from plants is odorless and safe by itself, and has the advantage that it does not require a large-scale facility as a deodorant device. But big. The deodorant containing a deodorant active ingredient obtained from a plant as a main component can be used for all kinds of odors in daily life, for example, amines such as trimethylamine which is putrid odor of fish and meat, and sulfurized which is putrid odor of egg and milk. Hydrogen, mercaptans such as methyl mercaptan, which is a putrefactive odor of vegetables and garbage, ammonia with toilet odor, cigarette odor, and organic acids that cause sweat and body odor. is there.

[0009]

However, since the above-mentioned conventional deodorant usually contains water as a solvent, when it is put into a spray can and used as a spray deodorant for shavers, the spray can becomes corroded. There was a problem of doing. In view of such circumstances, an object of the present invention is to provide a spray deodorant for a shaver which has an excellent deodorizing effect on a shaver and has less corrosion of a spray can.

[0010]

Means for Solving the Problems In order to solve the above problems, the inventors have made various studies. As a result, it was confirmed by experiments that the corrosion of the spray can can be reduced by controlling the water content to 20% by weight or less based on the whole deodorant, and the present invention was completed. Therefore, shaver spray deodorant according to the present invention is a deodorant containing deodorant active ingredients obtained from plants, water content
20% by weight or less based on the whole deodorant ,
5% by volume of paraffin based on the entire contents of the spray can
In addition to the above, hexane is also included .

The spray deodorant for a shaver of the present invention (hereinafter simply referred to as "deodorant") needs to contain a deodorant active ingredient obtained from a plant. As deodorant active ingredients obtained from plants, plant leaves, petiole,
Fruits, stems, roots, deodorant active ingredients extracted from various organs such as bark, plant essential oils, etc., the deodorant of the present invention, the deodorant active ingredients extracted from these plants and plant essential oils Must include at least one of them. This is because the deodorant active ingredient extracted from the plant can be deodorized by chemically reacting with a malodor or an off-flavor. In addition, vegetable essential oils are generally obtained mainly by steam distillation, pressing and the like, and are volatile and emit an odor. This is because an odor and an unpleasant odor can be quickly eliminated by the effect of being canceled out. Moreover, the odor after the reaction is not unpleasant due to the fragrance of the essential oil.

The type of plant for obtaining the deodorant active ingredient extracted from the plant is not particularly limited, but, for example, oxalis, prickles, hemlock, ginkgo, black pine, larch, red pine, kiri, holly oak, lilac , Butterbur, butterflies, camellia or forsythia are preferred. However, the present invention is not limited to these, and other than the above-mentioned Lentaceae, Pinaceae plants, or plant cell culture systems derived and cultured from these plants can also be widely used. Further, the plant may be used alone or in combination of two or more.

The method for extracting the deodorant active ingredient from the plant is not particularly limited. For example, water or an alcohol such as ethanol or methanol, methyl ethyl ketone, acetone or the like may be added to the above-mentioned raw material plant as an extraction solvent. And a method of adding a hydrophilic organic solvent such as ketones and heat-extracting the deodorant active ingredient using a Soxhlet extractor or the like. As the extraction solvent, a mixed solvent of water and the hydrophilic organic solvent may be used in combination.

The obtained extract is, for example, as it is, or diluted or concentrated with an appropriate solvent.
It is used after being concentrated to dryness. As the deodorant active ingredient and the extract, only one kind may be used, or 2
Mixtures of more than one species may be used. The extraction operation is not limited to the single-stage extraction, and if necessary, using a hydrophobic organic solvent, for example, petroleum ether, hexane, ethyl acetate, etc., to remove aroma components such as green odor contained in the raw material plants. It may be eluted and removed in advance. In addition, the said fragrance | flavor component can also be removed by a steam distillation method.

[0015] Deodorant active ingredients extracted from plants are generally non-volatile. As described above, the deodorant of the present invention may contain a plant essential oil as a deodorant active ingredient obtained from a plant. The plant essential oil that can be used is not particularly limited, for example, Avies oil, Cassia oil,
Citronella oil, cinnamon oil, sweet orange oil, geranium oil, nutmeg oil, peppermint oil, peppermint mitcham oil, vetiver oil, bergamot oil, petiglen oil, lavandin oil, lavender oil, lime oil, rose oil, lemon oil, lemongrass oil And hiba oil. As the vegetable essential oil, only one kind may be used, or two or more kinds may be used in combination.

The content of the essential oil of the plant is not particularly limited.
It is preferably 0.1% by volume. If the upper limit of the range is exceeded, the fragrance of the essential oil of the plant becomes too strong, and the masking action may give an unpleasant feeling. Further, when the value is below the lower limit of the above range, there is a possibility that the effect of offsetting with the odor may not be exhibited.

If necessary, a fragrance may be contained in order to further add an aroma. As described above, the deodorant of the present invention needs to have a water content of 20% by weight or less based on the whole deodorant. If the water content exceeds 20% by weight, the corrosion of the spray can becomes large.

The deodorant of the present invention is not particularly limited, but preferably contains glyoxal. This is because the effect of glyoxal reinforces the deodorizing power and gives stability over time. When glyoxal is contained, the content thereof is not particularly limited, but is 0.1 to 500 parts by weight based on 1 part by weight of the deodorant active ingredient (for example, plant extract) obtained from the plant. Is preferred.

The deodorant of the present invention is not particularly limited, but preferably contains a surfactant as a shaver detergent. When a shaver is used, sebum, skin, mustache residue, bacterial cells, and the like adhere to the shaver, and a bad smell is generated from these. When the deodorant of the present invention contains a surfactant, after using this deodorant, washing the shaver with water not only eliminates the bad smell due to the effect of the deodorant active ingredient obtained from the plant, This is because the odor source is washed away by the cleaning effect of the surfactant, and as a result, the odor is not generated again. In addition, the sebum, skin, mustache residue, and the like cause a decrease in the function of the shaver. However, the surfactant can be washed off as described above, which is effective in terms of maintenance of the shaver. It also has a great shaver foam effect.

The surfactant which can be used is not particularly limited as long as it imparts a shaving cleaning effect. Cationic surfactants, anionic surfactants, amphoteric surfactants, nonionic surfactants Either may be used. When the deodorant of the present invention is sprayed on a shaver, the deodorant preferably has a mousse shape (fine bubble shape). This is because if the mousse is formed, the cleaning effect is further enhanced by the fine bubbles. Specific examples of the surfactant capable of forming a mousse are not particularly limited,
For example, derivatives such as polyethylene glycol nonyl phenyl ether, polyethylene glycol octyl phenyl ether and the like can be mentioned.

When a surfactant is contained, its content is not particularly limited, but is preferably 1 to 20% by weight based on the whole deodorant. Further, only one surfactant may be used, or two or more surfactants may be used in combination. The deodorant of the present invention may contain a thickener such as hydrogenated castor oil, if necessary.

The deodorant of the present invention is not particularly limited, but preferably contains an antibacterial agent. Either kill the cells attached to the shaver by the effect of the antibacterial agent,
Alternatively, by preventing its growth, it is possible to prevent malodor generated from the cells and to prolong the life of the deodorant. The antibacterial agent that can be used is not particularly limited, but is preferably one that dissolves in water, alcohols, or other organic solvents. Specific examples thereof are not particularly limited. For example, quaternary ammonium compounds such as benzalkonium chloride and cetylpyridinium chloride, sodium lauryl sulfate, or
Phenol compounds such as isopropylmethylphenol and resorcinol are exemplified. Among these,
Benzalkonium chloride, cetylpyridinium chloride, isopropylmethylphenol and the like are preferred. In addition, as the antibacterial agent, one that also functions as a surfactant may be used.
Such an antibacterial agent is not particularly limited. For example, the above-mentioned quaternary ammonium compounds (cationic surfactant) such as benzalkonium chloride and cetylpyridinium chloride, sodium lauryl sulfate (anionic surfactant) ) And the like.

When the deodorant contains an antibacterial agent, the content thereof is not particularly limited, but is based on 1 part by weight of the deodorant active ingredient (for example, plant extract) obtained from the plant.
It is preferably 0.1 to 10 parts by weight. Antimicrobial agents
One type may be used alone, or two or more types may be used in combination. The deodorant of the present invention may contain an organic solvent as a diluent, if necessary. The organic solvent that can be used is not particularly limited. For example, hydrophilic and hydrophobic organic solvents such as alcohols such as methanol and ethanol, ketones such as methyl ethyl ketone and acetone, and petroleum ether, hexane, and ethyl acetate And the like. When the organic solvent is contained, the content thereof is not particularly limited. For example, the organic solvent is preferably 99 parts by volume or less based on 1 part by volume of the deodorant excluding the organic solvent.

Further, the pH of the deodorant is not particularly limited, but in order to further enhance the deodorizing power and enhance the safety, the pH is slightly acidic to slightly alkaline (for example, 5 to 5).
About 8). The method of adjusting the pH is not particularly limited, and examples thereof include a method of adding an alkaline solution such as an aqueous solution of potassium hydroxide or an aqueous solution of sodium hydroxide, or a solution having a buffering action.

[0025] The deodorant of the present invention, <br/> also the liquidity paraffin including. When containing liquid paraffin, after shaver washing,
Alternatively, by spraying the deodorant of the present invention onto the shaver after using the shaver, the shaver can be used smoothly and in an odorless state. That is, by containing liquid paraffin, a lubricating effect can be obtained, which is also effective in terms of shaver maintenance.

The content of the fluidized paraffin is 5 volume% or more to the total SPRAY cans contents. If the content is less than 5% by volume, the lubricating effect described above cannot be sufficiently obtained. The deodorant of the present invention also contains hexane.
No. In making the spray deodorant of this invention, liquid paraffin is typically poured into a spray can separately from the other ingredients. At that time, the liquid paraffin is difficult to inject into the spray can as it is. Therefore, if the liquid paraffin is diluted with hexane, the liquid paraffin can be easily injected into the spray can. The amount of hexane used when diluting liquid paraffin with hexane is not particularly limited, but is 0.5 to 1 part by volume of liquid paraffin.
About 2 parts by volume is preferred.

Injection (spraying) of the spray deodorant of the present invention
The format is not particularly limited. For example, LPG
(Liquefied natural gas), DME (dimethyl ether), chlorofluorocarbon gas, carbon dioxide gas, compressed air, etc., using one or two or more types of propellants for pressure, or using negative pressure of fluid like spraying Or a type utilizing pressure from the outside of the container. In addition, when using a propellant, the amount of use is not particularly limited,
The content is preferably about 20 to 80% by volume based on the whole content of the spray can.

The shape, size, material and the like of the spray can are not particularly limited.

[0029]

When a deodorant active ingredient obtained from a plant is included, the odor generated from the shaver can be effectively eliminated. Further, the water content was set to 2 with respect to the whole deodorant.
When the content is controlled to 0% by weight or less, corrosion of the spray can is reduced.
