Description

[Detailed Description of the Invention] [Industrial Application Field] This invention deodorizes skin odor generated by a shaver, particularly sweat odor, body odor, or foreign odor generated from bacterial cells attached to the shaver. , relates to a deodorant for shavers that has a lubricating effect.

[Conventional technology]

Generally, the sources of bad odors and abnormal odors are factory smoke, waste liquid, cigarettes, urine, and kitchen waste.
There are many different types of them.

In the home, odors from the toilet, kitchen, pets, cigarettes, etc. cause discomfort, irritation, headaches, and the like. In particular, when air conditioning equipment is in operation, it is often kept in a closed room, so countermeasures against these bad odors and strange odors have become a big problem.

Conventionally, methods for eliminating such bad odors and foreign odors can be broadly classified into the following methods (1) to (2).

■ Sensory deodorization method: A method that uses the scent emitted by aromatic substances (fragrant essential oils, etc.) to cover up bad odors and foreign odors, making them difficult to detect.

■ Physical deodorization methods: Diluting and removing bad odors through ventilation and diffusion, adsorbing odors using silica gel or activated carbon, or including odorous substances using clathrate compounds such as cyclodextrino. Method.

■ Chemical deodorization method: A method of chemically reacting (neutralization, addition, condensation, oxidation, etc.) with malodor and off-flavor components to make them odorless. For example, direct combustion method and oxidation method using oxidizing agents such as ozone and potassium permanganate.

■ Biological deodorization method 2. Reduces and kills microorganisms that cause spoilage.
How to prevent spoilage and prevent the occurrence of bad odors.

The sensory deodorization method described in (2) above is a method that is mainly practiced in households, but with fragrant substances, the ability to remove odorous substances is based on an electric field, and when fragrance and bad odors are mixed, the sensual deodorization method The disadvantage is that it is difficult to balance the odor.

Moreover, since people have different tastes in scent, and in some cases, it may cause a feeling of disgust, it is difficult to apply it to shavers.

The physical deodorization method (2) has been widely used for a long time, but there are problems in terms of equipment, in the adsorbent, desorption of odor substances due to temperature changes, and in maintenance.

With the chemical deodorization method described in (2) above, it is difficult to select substances that effectively react with odorous substances in a wide variety of bad odors, and there are concerns about the safety of the chemicals used and the risk of deterioration of the shaver components. It is not practical in that there is a risk of

The biological deodorizing method described in (2) is not suitable for the purpose of removing atmospheric odors, and has disadvantages such as the need for equipment and the time it takes for the deodorizing effect to occur. There were advantages and disadvantages to applying this method to shaver deodorization (Industrial Research Association, “New Deodorization Technology” by Susumu Kokubu (1)
(981)).

Therefore, some of the inventors proposed that as an active ingredient of deodorant,
We attempted to use extracts obtained from plants, and as a result, we developed a deodorant whose main ingredient is a deodorizing active ingredient obtained from plants, and have already applied for a patent (Japanese Patent Laid-Open No. 1-218
(See Publication No. 456, etc.).

Deodorizing active ingredients obtained from plants are themselves odorless and safe, and have the additional advantage of not requiring large-scale deodorizing equipment, so they have great potential in the future.

The above-mentioned deodorant, whose main ingredient is a deodorizing active ingredient obtained from plants, can eliminate all kinds of odors in daily life, such as amines such as trimethylamine, which is the odor of rotten fish and meat, and sulfur, which is the odor of rotten eggs and milk. It has a high deodorizing effect on all odors, including hydrogen, mercaptans such as methyl mercaptan, which is the smell of rotting vegetables and garbage, ammonia, which is the smell of toilets, organic acids, which are the cause of odors such as tobacco odor, sweat, and body odor. be.

[Problem to be solved by the invention]

However, the above-mentioned conventional deodorants themselves are non-volatile, and unless they are manipulated to act directly on the odor source, there is a problem in that they are not sufficiently fast-acting and deodorizing. Further, there was a problem in that even a small amount of the odor may remain. Further, there is a problem in that the odor after the deodorant and the malodor react may become unpleasant.

In view of these circumstances, the present invention aims to reduce the odor that occurs after using a shaver, especially the odor of sweat and body odor, or the bad odor that occurs from sebum, skin, and beard residue adhering to the shaver. However, it is an object of the present invention to provide a deodorizing agent for shavers that always exhibits fast-acting and high deodorizing effects and is also effective in terms of shaver maintenance.

[Means to solve the problem]

In order to solve the above problem, a shaver according to the present invention is provided.
The deodorant is a deodorant containing an active deodorizing ingredient extracted from plants, glyoxyl, an antibacterial agent, and a plant essential oil, and is characterized by containing liquid paraffin as shaver oil. It is.

The deodorant for shavers of this invention (hereinafter simply referred to as "deodorant") deodorizes components extracted from various organs such as leaves, petioles, fruits, stems, roots, and bark of plants. It is necessary to include it as an active ingredient.

The type of plant for obtaining the deodorizing active ingredient is not particularly limited, but includes, for example, oxalis, hectylatum, hemlock, ginkgo, black pine, larch, red pine, tung thorn, holly osmanthus, lilac, osmanthus, butterbur, japonica, or Forsythia etc. are preferred. However, it is not necessary to be limited to these, and plants of the Oleaceae family and Pinaceae family other than those mentioned above, or plant cell culture systems induced and cultured from these plants, etc. can also be widely used.

Further, only one type of plant may be used, or
Two or more types may be used in combination.

There are no particular limitations on the method for extracting deodorizing active ingredients from plants, but for example, the above-mentioned raw material plant may be used as an extraction solvent, such as water, alcohols such as ethanol or methanol, or ketones such as methyl ethyl ketone or acetone. Examples include a method of adding a hydrophilic organic solvent such as and thermally extracting the deodorizing active ingredient using a Soxhlet extractor or the like. As the extraction solvent, a mixed solvent of water and the above hydrophilic organic solvent may be used in combination.

The obtained extract can be used, for example, as is or
It is used by diluting it with an appropriate solvent, concentrating it, or concentrating it to dryness. The deodorizing active ingredient and the extract are 1
Seeds alone may be used, or two or more types may be used in combination. Note that the extraction operation is not limited to the -stage extraction, and if necessary, a hydrophobic organic solvent such as petroleum ether, hexane, ethyl acetate, etc. may be used to extract aroma components such as grassy odor contained in the raw material plants. You may elute and remove it in advance. Note that the aroma component can also be removed by steam distillation.

Deodorizing active ingredients obtained from plants generally have non-volatile properties.

The deodorant of this invention needs to contain glyoxal in order to reinforce its deodorizing power and to provide stability over time. Although the content of glyoxal is not particularly limited, it is preferably 0.1 to 500 parts by weight based on 1 part by weight of the deodorizing active ingredient (or extract) obtained from the plant. The odor agent must contain an antibacterial agent in order to kill the bacteria adhering to the shaver or prevent their proliferation, thereby preventing the bad odor generated from the bacteria. Antibacterial agents include, but are not particularly limited to, surfactants, isopropylmethylphenol, and the like. The surfactant may be any of cationic surfactants, anionic surfactants, amphoteric surfactants, and nonionic surfactants, but among these, benzalkonium chloride, cetylpyridinium chloride, etc. are particularly preferred. . Although the content of the antibacterial agent is not particularly limited, it is preferably 0.1 to 10 parts by weight per 1 part by weight of the deodorizing active ingredient (or extract) obtained from the plant.

The deodorant of this invention needs to contain plant essential oil. Plant essential oils are mainly obtained by steam distillation, and are volatile and emit aromas. This is because the aroma of the plant essential oil and the malodor or foreign odor are mixed and the odor is sensually offset, giving the deodorant quick-acting properties and reinforcing its deodorizing power.

There are no particular restrictions on the plant essential oils that can be used, but
For example, avinis oil, cassia oil, citronella oil, cinnamon oil, sweet orange oil, geranium oil, nutmeg oil, peppermint oil, peppermint mitchum oil, vetiver oil, hergamo sotho oil, vetygrain oil, lavandin oil, lavender oil, lime oil, rose oil, lemon oil, lemongrass oil, etc. Only one type of plant essential oil may be used, or two or more types may be used in combination.

The content of the plant essential oil is not particularly limited, but for example, the content of the plant essential oil is 0. OOO1~0゜1 volume%
It is preferable that If the upper limit of this range is exceeded, the aroma of the plant essential oil will become too strong, which may give an unpleasant feeling due to its masking effect. Also,
This is because if the amount is below the lower limit of the above range, there is a possibility that the effect of offsetting the odor may not be exhibited.

In addition, if necessary, to add more aroma,
It may also contain fragrance.

In order for the deodorant of the present invention to be effectively used in shavers, it is necessary to contain liquid paraffin as shaver oil. This is because by containing liquid paraffin, a hot water effect can be obtained, which is effective in maintaining the shaver.

Although the content of liquid paraffin is not particularly limited, it is preferably, for example, 5% by volume or more based on the entire deodorant.

Note that the deodorant of the present invention may contain ethanol, if necessary. If ethanol is included, the content of ethanol is not particularly limited, but for example, for 1 part by volume of the deodorant excluding ethanol,
Preferably, ethanol is contained in an amount of 99 parts by volume or less.

Further, the pH of the deodorant is not particularly limited, but it is preferably adjusted from weakly acidic to weakly alkaline (for example, about 5 to 8) in order to further enhance the deodorizing power. The method for adjusting the pH is not particularly limited, but includes, for example, a method of adding an alkaline solution such as an aqueous potassium hydroxide solution or an aqueous sodium hydroxide solution, a buffering solution, and the like. Note that pH adjustment is usually performed in a state that does not contain liquid paraffin. In addition, as described above, when ethanol is included, it is carried out in a state that does not contain both liquid paraffin and ethanol.

There are no particular limitations on the method of using the deodorant of this invention. For example, a deodorant may be sealed in a spray container together with a propellant such as LPG, and the pressure of the propellant may be used to spray the deodorant. In this case, the shape of the spray container,
The size, material, etc. are not particularly limited. Further, the liquid may be sprayed by using negative pressure of the fluid as in a sprayer, or by using pressure from outside the container.

[For production]

Incorporating deodorizing active ingredients extracted from plants can eliminate odors that occur after using a shaver, especially sweat odor and body odor, as well as bad odors that occur from sebum, skin, beard residue, etc. that adhere to the shaver. On the other hand, the deodorizing effect becomes higher.

When glyoxal is included, the deodorizing power is reinforced and the stability of the deodorizing power over time is improved.

When an antibacterial agent is included, the bad odor generated by the bacteria is inhibited by killing the bacteria attached to the shaver or preventing their proliferation.

By incorporating plant essential oils, the aroma of plant essential oils and
The effect of sensually canceling out the odor by mixing it with bad odor and foreign odor provides fast-acting properties and strengthens the deodorizing power.

Including liquid paraffin allows the shaver to move smoothly, which is also effective in terms of maintenance.
