JPH0693909B2 - Deodorant for shaver - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention eliminates the skin odor generated in a shaver, in particular, the sweat odor, body odor, or the offensive odor generated from the bacterial cells attached to the shaver, and at the same time, lubricates the odor. The present invention relates to an effective deodorant for shavers.

[Conventional technology]

Generally, foul odors and offensive odors are generated from factory exhaust gases, waste liquids, cigarettes and raw sewage, and kitchen kitchen waste.
There are various types of them. 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, there are roughly classified into the following methods as a method for eliminating such a bad odor or an offensive 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 difficult to sense.

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 deodorization method: A method in which odors are obtained by chemically reacting (neutralizing, adding, condensing, oxidizing, etc.) with malodorous or offensive odor components. 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 practiced in general households, but aromatic substances have a limited ability to remove odorous substances, and aroma and malodor when aroma and malodor are mixed There is a drawback that it is difficult to balance.
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 physical deodorizing method has been widely used for a long time, but it has problems in terms of equipment, desorption of odorous substances due to temperature change in the adsorbent, and maintenance.

In the above chemical deodorization method, it is difficult to select a substance that effectively reacts with odorous substances in a wide variety of malodors, and there is a risk of deterioration in chemicals used and shaver components. In some respects it is not practical.

The above-mentioned biological deodorizing method is not suitable for the purpose of removing the odor of the atmosphere, and has the drawbacks that it requires equipmentization and that it takes time to develop the deodorizing effect.

As described above, there are merits and demerits in applying the conventional deodorizing method to the deodorizing of the shaver (see the Industrial Research Committee “New Deodorizing Technology”, Susumu Kokube (1981)).

Therefore, some of the inventors of the present invention, as an active ingredient of the deodorant,
An attempt was made to use an extract obtained from a plant, and as a result, a deodorant containing a deodorant active ingredient obtained from a plant as a main component was developed and a patent has already been applied for (Japanese Patent Laid-Open No. 1-2184).
(See No. 56, etc.).

The deodorant active ingredient obtained from plants is odorless and safe by itself, and since it has the advantage of not requiring large-scale equipment as a deodorizing device, it is expected to continue in the future.

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 rotting odor of fish and meat, and sulfurization which is a rotting 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.

[Problems to be Solved by the Invention]

However, the above-mentioned conventional deodorant itself is non-volatile, and there is a problem that it is not sufficiently fast and deodorant unless it is operated so as to directly act on the odor source. In addition, there is a problem that even a small amount of odor may remain. Further, there is a problem that the odor after the deodorant reacts with the bad odor may become an unpleasant odor.

In view of such circumstances, the present invention, among the above-mentioned odors, against the odors generated after the use of the shaver, especially sweat odors and body odors, or the sebum attached to the shaver, the skin, and the bad odors generated from the mustache residue. Therefore, it is an object of the present invention to provide a deodorant for a shaver that always exhibits a fast-acting effect and a high deodorizing effect, and is also effective in terms of shaver maintenance.

[Means for Solving the Problems]

In order to solve the above problems, a deodorant for shavers according to the present invention is a deodorant containing a deodorant active ingredient extracted from plants, glyoxal, an antibacterial agent, and a plant essential oil, and liquid paraffin as shaver oil. It is characterized by including.

The deodorant for shavers of the present invention (hereinafter, simply referred to as "deodorant") is effective for deodorizing components extracted from plant organs such as leaves, petioles, fruits, stems, roots and bark. It is necessary to include it as an ingredient.

The type of plant for obtaining the deodorant active ingredient is not particularly limited, but, for example, oxalis, dokudami, hemlock, ginkgo, black pine, larch, red pine, kiri,
Holly, lilac, buttercup, butterbur,
Tsuwabuki, forsythia and the like are preferable. However, it is not necessary to be limited to these, but other oleaceae other than the above,
Pineaceae plants or plant cell culture systems derived from these plants by induction culture can also be widely used. Also, only one kind of plant may be used, or 2
You may use together 1 or more types.

The method for extracting the deodorant active ingredient from the plant is not particularly limited, but, for example, water or an alcohol such as ethanol or methanol, or methyl ethyl ketone or ketones such as acetone is extracted as an extraction solvent into the raw material plant. A method of adding a hydrophilic organic solvent as described above 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
It is used by diluting it with an appropriate solvent, concentrating it, or concentrating it to dryness. The deodorant active ingredient and the extract are 1
Only one species may be used, or two or more species may be mixed and used. Note that 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. may be used to remove aroma components such as blue odor contained in the raw material plant. It may be eluted and removed in advance. The aroma components can be removed by a steam distillation method.

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

The preservative of the present invention needs to contain glyoxal in order to reinforce the deodorizing power and to impart stability over time. The content of glyoxal is not particularly limited, but it is preferably 0.1 to 500 parts by weight with respect to 1 part by weight of the deodorant active ingredient (or extract) obtained from the plant.

The deodorant of the present invention needs to contain an antibacterial agent in order to kill the microbial cells adhering to the shaver or prevent its growth, thereby preventing the malodor generated from the microbial cells. The antibacterial agent is not particularly limited, but examples thereof include a surfactant and isopropylmethylphenol. As the surfactant, any of a cationic surfactant, an anionic surfactant, an amphoteric surfactant and a nonionic surfactant may be used, and among them, benzalkonium chloride, cetylpyridinium chloride and the like are particularly preferable. . The content of the antibacterial agent is not particularly limited, but is preferably 0.1 to 10 parts by weight with respect to 1 part by weight of the deodorant active ingredient (or extract) obtained from the plant.

The deodorant of this invention needs to contain a vegetable essential oil. The plant essential oil is generally obtained mainly by a steam distillation method and is volatile and emits an aroma. This is because the odor of the plant essential oil is mixed with a bad odor or an offensive odor, and the odor is sensuously offset, so that the deodorant is given a rapid effect and the deodorant power is reinforced.

The plant essential oil that can be used is not particularly limited,
For example, abies oil, cassia oil, citronella oil, cinnamon oil, sweet orange oil, geranium oil, nutmeg oil, peppermint oil, peppermint mitchum oil, vetiver oil, bergamot oil, petigrain oil, lavandin oil, lavender oil, lime oil, rose Oil, lemon oil, lemongrass oil and the like can be mentioned. 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 preferably 0.0001 to 0.1% by volume with respect to the entire deodorant. 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 necessary, in order to add more aroma,
Perfume may be included.

The deodorant of the present invention needs to contain liquid paraffin as shaver oil so that it can be effectively used for shavers. This is because the inclusion of liquid paraffin provides a lubricating effect and is effective in terms of shaver maintenance.

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

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

The pH of the deodorant is not particularly limited,
In order to further enhance the deodorizing power, it is preferable to adjust from weakly acidic to weakly alkaline (for example, about 5 to 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 and an aqueous solution of sodium hydroxide, a method of adding a solution having a buffering effect, and the like. The pH can be adjusted by
Usually, it is carried out in the state of not containing liquid paraffin. In addition, as described above, when ethanol is contained, it is performed in a state where neither liquid paraffin nor ethanol is contained.

The method of using the deodorant of the present invention is not particularly limited. For example, a deodorant may be enclosed in a spray container together with a propellant such as LPG, and the pressure of the propellant may be used for injection. 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.

[Work]

By adding the deodorant active ingredient extracted from plants, to the odor generated after use of the shaver, especially sweat odor and body odor, or the bad odor generated from sebum, skin, mustache residue, etc. attached to the shaver. , The deodorizing effect is enhanced.

The inclusion of glyoxal enhances the deodorizing power and improves the stability of the deodorizing power over time.

When the antibacterial agent is contained, the microbial cells adhering to the shaver are killed or their growth is prevented, thereby preventing the malodor generated from the microbial cells.

By adding the vegetable essential oil, the aroma of the vegetable essential oil,
Due to the effect of mixing offensive odors and offensive odors and sensuously offsetting the odors, fast-acting effect is imparted and deodorant power is reinforced.

When liquid paraffin is included, the shaver moves smoothly, which is effective in terms of maintenance.
