Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention eliminates the skin odor generated on a shaver, in particular, the sweat odor, body odor, or the offensive odor generated from the fungus body adhering to the shaver, and at the same time has a deodorizing effect for the shaver. Regarding agents.

[0002]

2. Description of the Related Art Generally, smoke and waste liquid from factories, cigarettes and raw sewage, kitchen garbage, and the like are sources of offensive odors and offensive odors, and there are various types thereof. At home, odors from toilets, kitchens, pets, cigarettes, etc. cause discomfort, frustration, headaches, and the like. In particular, when the air conditioner is operated, it is often kept in a closed room, so countermeasures against these malodors and offensive odors are a big problem.

Conventionally, the following methods (1) to (3) are roughly classified as methods for eliminating such an offensive odor or a strange odor. Sensory deodorization method: A method that masks offensive odors and offensive odors by the fragrance emitted by aromatic substances (fragrance essential oils, etc.) to make them less sensitive Physical deodorization method: A method of diluting and removing a bad odor by ventilation / diffusion, adsorbing an odor using silica gel or activated carbon, or encapsulating an odorous substance with an inclusion compound such as cyclodextrin.

Chemical deodorizing method: A method of deodorizing by chemically reacting (neutralizing, adding, condensing, oxidizing, etc.) with a malodorous or offensive odor component. For example, a direct flame combustion method or an oxidation method using an oxidizing agent such as ozone or potassium permanganate. Biological deodorant method: destroying the microorganisms that cause decay,
A method to prevent spoilage and prevent the generation of foul odors.

The above-mentioned sensory deodorizing method is a method mainly used in ordinary households. However, aromatic substances have a limited ability to remove odorous substances, and when odor and malodor are mixed. It has the drawback that it is difficult to balance the aroma and odor. Further, since the scent has a preference for human beings, and in some cases, it may cause an aversion, it is difficult to apply it to a shaver.

The above-mentioned physical deodorizing method has been widely used since ancient times, but it has problems in terms of equipment, desorption of odorous substances due to temperature change in the adsorbent, and maintenance. is there. The above chemical deodorant method is
It is difficult to select a substance that reacts effectively with a wide variety of odorous substances, and it is not practical in terms of the safety of chemicals used and the risk of deterioration of shaver constituent members.

The above-mentioned biological deodorizing method is not suitable for the purpose of removing the odor of the atmosphere, and it has the drawbacks that it requires equipment and takes a long time to develop the deodorizing effect. As described above, there are merits and demerits in applying the conventional deodorizing method to the deodorizing of shavers (see the Industrial Research Committee “New Deodorizing Technology”, Susumu Kokube (1981)). Therefore, some of the inventors 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 was used. The agent has been developed and a patent application has already been made (see Japanese Patent Application Laid-Open No. 1-218456).

The deodorant active ingredient obtained from plants is odorless and safe by itself, and in addition, it has the advantage of not requiring large-scale equipment as a deodorant device, and is therefore expected in the future. However, it is big. The deodorant containing a deodorant active ingredient as a main component obtained from plants is used for all kinds of odors in daily life, for example, amines such as trimethylamine which is a rotten odor of fish and meat, and sulfurization which is a rotten odor of eggs and milk. Hydrogen, mercaptans such as methyl mercaptan which is a perishable odor of vegetables and garbage, ammonia in toilet odors, cigarette odors, organic acids that are odors causing sweat and body odor, etc. is there. In addition, the inventors
To enhance the deodorant power of deodorant active ingredients obtained from plants
It is obtained from plants to give it stability over time.
In addition to the deodorant active ingredients, the deodorant containing glyoxal
We are also developing odorants.

[0009]

However, the conventional deodorant described above has a problem that the deodorizing effect is not sufficient for shavers. In view of such circumstances, it is an object of the present invention to provide a deodorant having an excellent deodorizing effect on shavers.

[0010]

In order to solve the above-mentioned problems, the inventors have made various studies, and as a result, have found the following things and completed the present invention. That is, when a shaver is used, sebum, skin, beard residues, fungus bodies and the like adhere to the shaver, and an offensive odor is generated from them. However, even if the conventional deodorant described above is used to eliminate this bad odor,
The malodor only disappears temporarily, and the shaver still has the malodor source such as the sebum. Therefore, after a while, the malodor again occurs from the malodor source. Therefore, as a deodorant for shaver, together with a deodorant active ingredient and glyoxal obtained from plants,
If a surfactant is used, after using this deodorant, washing the shaver with water not only eliminates the bad odor due to the effect of the deodorant active ingredient and glyoxal , but also the effect of the surfactant. The odor source is washed off by. As a result, the bad odor does not occur again.

Therefore, the deodorant for shaver according to the present invention comprises a deodorant active ingredient obtained from a plant and glyoxy.
A deodorant containing sar, which is characterized by containing a surfactant as a cleaning agent for shavers. The deodorant for shavers of the present invention (hereinafter, simply referred to as “deodorant”) needs to contain a deodorant active ingredient obtained from a plant.

As the deodorant active ingredient obtained from plants,
There are deodorant active ingredients extracted from various organs such as plant leaves, petioles, fruits, stems, roots and bark, and plant essential oils.The deodorant of the present invention is a deodorant extracted from these plants. It is necessary to include at least one of an active ingredient and plant essential oil. This is because the deodorant active ingredient extracted from a plant can be deodorized by chemically reacting with a bad odor or an offensive odor. In addition, plant essential oils are generally obtained mainly by a steam distillation method and are volatile and give off an aroma. However, the aroma of this plant essential oil is mixed with a bad odor or an offensive odor, and the odor is sensory. This is because the offensive odor or offensive odor can be quickly eliminated by the offsetting effect. Moreover, the odor of the plant essential oil makes the odor after the reaction uncomfortable.

The type of plant for obtaining the deodorant active ingredient extracted from the plant is not particularly limited, but examples thereof include oxalis, dokudami, hemlock, ginkgo, black pine, larch, red pine, kiri, holly lacquer, lilac. , Pearl oyster, butterbur, butterbur, forsythia, and the like are preferable. However, the present invention is not limited to these, and plants other than the above, such as Astragalus plants, Pinaceae plants, or plant cell culture systems derived from these plants by induction culture can also be widely used. Moreover, only one type of plant may be used, or two or more types may be used in combination.

The method for extracting the deodorant active ingredient from the plant is not particularly limited, but, for example, water or alcohols such as ethanol and methanol, methyl ethyl ketone, acetone and the like can be used as an extraction solvent for the above-mentioned raw material plants. The method of adding a hydrophilic organic solvent such as ketones and thermally extracting the deodorant active ingredient using a Soxhlet extractor or the like can be mentioned. 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 with a suitable solvent or concentrated,
It is used by concentrating to dryness. As the deodorant active ingredient or the extract, only one kind may be used, or 2
You may mix and use 1 or more types. The extraction operation is not limited to one-stage extraction, and if necessary, a hydrophobic organic solvent, for example, petroleum ether, hexane, ethyl acetate, etc., to use aroma components such as blue odor contained in the raw material plant. It may be eluted and removed in advance. The aroma component can be removed by a steam distillation method.

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 mitchum oil, vetiver oil, bergamot oil, petiglen oil, lavandin oil, lavender oil, lime oil, rose oil, lemon oil, lemongrass oil Etc. 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 plant essential oil is not particularly limited, but is, for example, 0.0001 to 0.001 to the total amount of the deodorant.
It is preferably 0.1% by volume. If the content exceeds the upper limit of this range, the fragrance of the plant essential oil becomes too strong, and the masking effect may give an unpleasant feeling. On the other hand, if the content is less than the lower limit of the above range, the effect of canceling out the odor may not be exhibited.

If desired, a fragrance may be included in order to add an aroma. Deodorant of the present invention, it is necessary to include surfactant as a cleaning agent for sheet Eba. The surfactant that can be used is not particularly limited as long as it gives a cleaning effect to the shaver, and any of a cationic surfactant, an anionic surfactant, an amphoteric surfactant and a nonionic surfactant can be used. Good.

When the deodorant of the present invention is used by spraying on a shaver as described later, it is preferable that the deodorant becomes a mousse (fine air bubbles) at the time of spraying. This is because if it becomes a mousse, the cleaning effect is further enhanced by the fine bubbles. Specific examples of the surfactant capable of forming a mousse are not particularly limited, and examples thereof include polyethylene glycol-based polyethylene glycol nonylphenyl ether, polyethylene glycol octylphenyl ether, and other derivatives.

The content of the surfactant is not particularly limited, but it is preferably 1 to 20% by weight with respect to the entire deodorant. The surfactant may be used alone or in combination of two or more. The deodorant of the present invention may optionally contain a thickener such as hydrogenated castor oil.

[0021] The deodorant of the present invention, it is necessary to include the glyoxal. By the effect of glyoxal,
This is because the deodorizing power is reinforced and the temporal stability is imparted. The content of glyoxal is not particularly limited, deodorizing active ingredients obtained from the plants (e.g., plant extracts) per 1 part by weight, is preferably 0.1 to 500 parts by weight.

The deodorant of the present invention is not particularly limited, but preferably contains an antibacterial agent. Depending on the effect of the antibacterial agent, kill the bacteria attached to the shaver,
Alternatively, by preventing its growth, it is possible to prevent the malodor generated from the bacterial cells and to prolong the life of the deodorant. The antibacterial agent that can be used is not particularly limited, but those that are soluble in water, alcohols, or other organic solvents are preferable. Specific examples thereof include, but are not particularly limited to, for example, quaternary ammonium compounds such as benzalkonium chloride and cetylpyridinium chloride, sodium lauryl sulfate, or
Examples thereof include phenol compounds such as isopropylmethylphenol and resorcin. Among these, especially
Benzalkonium chloride, cetylpyridinium chloride, isopropylmethylphenol and the like are preferable. As the antibacterial agent, one that also serves as a surfactant may be used.
Such an antibacterial agent is not particularly limited, and examples thereof include quaternary ammonium compounds (cationic surfactants) such as benzalkonium chloride and cetylpyridinium chloride described above, sodium lauryl sulfate (anionic surfactants). ) And the like.

When the deodorant contains an antibacterial agent, the content thereof is not particularly limited, but the content thereof is 1 part by weight with respect to 1 part by weight of the deodorant active ingredient (eg, plant extract) obtained from the plant.
It is preferably 0.5 to 100 parts by weight. As the antibacterial agent, only one kind may be used, or two or more kinds may be used in combination. The deodorant of the present invention may contain ethanol as a diluent, if necessary. When ethanol is contained, the content of ethanol is not particularly limited, but for example, it is preferable that 99 parts by volume or less of ethanol be contained with respect to 1 part by volume of the deodorant excluding ethanol.

The pH of the deodorant is not particularly limited, but it is weakly acidic to weakly alkaline (for example, 5 to 5) in order to enhance the deodorizing power and safety.
It is preferably adjusted to about 8). The method for 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 and an aqueous solution of sodium hydroxide, a method of adding a solution having a buffering effect, and the like.

Regarding the method of using the deodorant of the present invention,
There is no particular limitation. For example, a deodorant is enclosed in a spray container together with one or more propellants such as LPG (liquefied natural gas), DME (dimethyl ether), CFC gas, carbon dioxide gas, compressed air, etc., and the pressure of the propellant is used. Then, it may be jetted (sprayed). In this case, the shape, size, material, etc. of the spray container are not particularly limited. Alternatively, the negative pressure of the fluid may be used as in the case of spraying, or the pressure from the outside of the container may be used for spraying.

[0026]

[Action] Deodorant active ingredient and glyoxa obtained from plants
If the deodorant active ingredient and glyoxal are contained together with the surfactant, the odor generated after the use of the shaver, especially sweat odor or body odor, or sebum attached to the shaver, skin, mustache residue, bacterial cells, etc. Eliminates the foul odor generated from the foul odor source. Further, since the surface-active agent rinses off the malodor source, the malodor does not occur again, so that the deodorizing effect is further enhanced.

Prepare a deodorant in the same manner as in 5, and add the obtained deodorant to L
Placed in a spray can with PG propellant.

Using the sprays containing the deodorants obtained in Examples 1 to 5 and Comparative Examples 1 to 5 described above, the deodorizing effect of each deodorant was examined as follows. Five shavers for the examples and five shavers for the comparative examples were prepared, and half of the beard of the face was shaved by the shavers of the examples, and the other half of the beard was shaved by the shavers for the comparative example. The deodorant of each Example and Comparative Example was sprayed on the inner and outer blades of the Example and Comparative Shavers after use for 2 seconds from the spray, and then the Shaver was immediately washed under running tap water. Then, the water droplets were removed, and the mixture was left at room temperature for 24 hours.

Then, 10 panelists with similar olfaction smelled the scent of the shaver, and the odor intensity sensory test and the pleasantness / discomfort degree sensory test were conducted at the same time. The odor intensity was evaluated by numerical values of 6 levels of 0, 1, 2, 3, 4, 5. Odor intensity 0 means "no odor", 1 means "findable odor", 2 means "smell that tells what odor it is",
3 is an "easy odor", 4 is a strong odor,
5 means "strong odor".

The degree of comfort and discomfort is +4, +3, +2, +
The evaluation was made with numerical values of 9 levels of 1, 0, -1, -2, -3 and -4. Pleasure and discomfort degree +4 is "extremely pleasant", +3 is "extremely pleasant", +2 is "pleasant", +1 is "somewhat pleasant", 0 is "not pleasant or unpleasant", -1 is "somewhat unpleasant", -2 means "uncomfortable", -3 means "very uncomfortable", and -4 means "extremely uncomfortable".

The results are shown in Table 2 below. In addition,
The results shown in Table 2 are average values of the 10 panelists. When the shaved shaver was left untreated for 24 hours, the odor intensity was 3.0 and the comfort level was -3.5.

[0035]

[Table 2]

As can be seen from Table 2, the deodorants obtained in Examples 1-5 were compared with the deodorants obtained in Comparative Examples 1-5.
It was confirmed that the deodorant effect was excellent and that the odor after the reaction was not unpleasant. -Comparative Examples 6 to 7-Comparative Examples 6 and 7 were prepared in the same manner as in Examples 1 and 2 except that the surfactant was not added, and thus the deodorant of the corresponding Comparative Example was prepared and obtained. The deodorant was placed in a spray can with the LPG propellant.

Using the sprays containing the deodorants obtained in Examples 1 to 5 and Comparative Examples 6 to 7, the cleaning effect of each deodorant was examined as follows. Example shaver 5
And two shavers for comparative examples were prepared, and dry shaving was performed with each shaver for 3 days. The deodorant of each Example and Comparative Example was sprayed onto the inner and outer blades of the Example and Comparative Shavers after use.
After spraying for 2 seconds, the shaver was immediately washed under running tap water for about 10 seconds with the switch kept on. Then, the cleaning effect was visually determined. The evaluation was performed according to the following.

◯: It was washed cleanly. B: Washed slightly cleanly. X: Not washed very well. As a result, the cleaning effect of the deodorants obtained in Comparative Examples 6 to 7 was “x to Δ”, while Examples 1 to 1
The cleaning effect of the deodorant obtained in No. 5 was “◯” in all cases. From this, the deodorants obtained in Examples 1 to 5 containing a surfactant are Comparative Examples 6 to 7 containing no surfactant.
It was confirmed that the deodorant obtained in 1. had a superior cleaning effect.

[0039]

Since the deodorant for shavers according to the present invention contains a deodorant active ingredient obtained from plants and glyoxal, the odor generated after the use of the shaver, particularly sweat odor and body odor. Alternatively, a high deodorizing effect can be exerted against a bad odor generated from sebum attached to the shaver, skin, beard residues, bacterial bodies and the like.

Since this deodorant also contains a surfactant, sebum attached to the shaver, skin, beard residue,
Since it is possible to wash off odor sources such as bacteria, the deodorizing effect is further enhanced. Also, the sebum, skin, beard residues, etc., cause the function of the shaver to deteriorate, but this deodorant can wash them off as described above, and therefore, in terms of maintenance of the shaver. Has a valid shaver form effect.
