Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention deodorizes skin odor generated by shavers, especially sweat odor, body odor, and foreign odors generated from bacterial cells attached to the shaver. Regarding spray deodorant.

0002

2. Description of the Related Art In general, bad odors and strange odors come from a wide variety of sources, such as factory smoke, waste liquid, cigarettes, human waste, and kitchen waste. 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.

[0003] Conventionally, methods for eliminating such bad odors and foreign odors can be broadly classified into the following methods (1) to (3). ■ 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 method: dilutes bad odors through ventilation and diffusion,
A method of removing odor substances, adsorbing odors using silica gel or activated carbon, or including odorous substances with clathrate compounds such as cyclodextrin.

[0004] Chemical deodorization method: A method of chemically reacting (neutralization, addition, condensation, oxidation, etc.) with malodor or 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: A method that kills microorganisms that cause spoilage, prevents spoilage, and prevents the occurrence of bad odors.

[0005] The above sensory deodorization method (2) is a method that is mainly practiced in households, but there is a limit to the ability of aromatic substances to remove odorous substances, and when fragrances and bad odors are mixed, The disadvantage is that it is difficult to balance the aroma and odor of In addition, people have different tastes in scent, and in some cases, it may cause a feeling of disgust.
Application to shavers is difficult.

[0006] The physical deodorizing method described above has been widely used for a long time, but there are problems in terms of equipment, desorption of odor substances due to temperature changes in the adsorbent, and maintenance. There is. The chemical deodorization method mentioned above is as follows:
It is difficult to select a substance that effectively reacts with odorous substances in a wide variety of malodors, and it is not practical in terms of the safety of the chemicals used and the risk of deterioration of shaver components.

The biological deodorizing method (2) is not suitable for the purpose of removing atmospheric odors, and has drawbacks such as the need for equipment and the need for time for the deodorizing effect to develop. As described above, there are advantages and disadvantages to applying conventional deodorizing methods to deodorizing shavers (see Kogyo Kenkyukai, "New Deodorizing Technology" by Susumu Kokubu (1981)). Therefore, some of the inventors attempted to use extracts obtained from plants as the active ingredients of deodorants, and as a result, they found that deodorants whose main ingredients are deodorizing active ingredients obtained from plants. A patent has already been applied for (see JP-A-1-218456, etc.).

[0008] Deodorizing active ingredients obtained from plants are themselves odorless and safe, and have the additional advantage of not requiring large-scale equipment as deodorizing devices, so they are expected to continue to be used in the future. However, it is large. 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. Hydrogen, mercaptans such as methyl mercaptan, which is the smell of rotting vegetables and garbage, ammonia, which is the smell of toilets, tobacco smell,
It has a high deodorizing effect on all odors such as organic acids that are thought to be the cause of sweat and body odor.

[0009]

[Problems to be Solved by the Invention] However, since the conventional deodorants mentioned above usually contain water as a solvent, when they are put into a spray can and used as a spray deodorant for shavers, the spray can corrodes. There was a problem. In view of these circumstances, it is an object of the present invention to provide a spray deodorant for shavers that has an excellent deodorizing effect on shavers and is less likely to corrode the spray can.

0010

[Means for Solving the Problems] In order to solve the above problems, the inventors have conducted various studies. As a result, it was confirmed through experiments that corrosion of spray cans could be reduced by suppressing the water content to 20% by weight or less based on the entire deodorant, and the present invention was completed. Therefore, the spray deodorant for shavers according to the present invention is a deodorant containing an effective deodorizing ingredient obtained from plants, and has a water content of
It is characterized in that the amount is 20% by weight or less based on the entire deodorant.

[0011] Spray deodorant for shavers of the present invention (
The deodorant (hereinafter simply referred to as "deodorant") must contain an active deodorizing ingredient obtained from plants. Deodorizing active ingredients obtained from plants include leaves, petioles, fruits,
There are deodorizing active ingredients extracted from various organs such as stems, roots, and bark, and plant essential oils, but the deodorant of this invention contains deodorizing active ingredients extracted from these plants and plant essential oils. Must include at least one. This is because deodorizing active ingredients extracted from plants can deodorize by chemically reacting with bad odors and foreign odors. In addition, plant essential oils
Generally, it is obtained mainly through steam distillation, compression, etc., and is volatile and emits an aroma.However, the aroma of this plant essential oil is mixed with a bad odor or foreign odor, and the odor is sensually canceled out. This is because malodors and foreign odors can be quickly deodorized. Moreover, the aroma of the plant essential oil makes the odor after the reaction less unpleasant.

[0012] The types of plants for obtaining the deodorizing active ingredients extracted from plants are not particularly limited, but include, for example, oxalis, hectica, hemlock, ginkgo, black pine, larch, red pine, thorn, holly osmanthus, and lilac. , osmanthus, butterbur, forsythia, or forsythia are preferred. However, it is not necessary to be limited to these, and plants other than those mentioned above such as Oleaceae, Pinaceae, or
Plant cell culture systems induced and cultured from these plants can also be widely used. Moreover, only one type of plant may be used, or two or more types may be used in combination.

[0013] The method for extracting the deodorizing active ingredient from plants is not particularly limited, but for example, the above-mentioned raw material plant may be used as an extraction solvent, such as water, alcohols such as ethanol and methanol, methyl ethyl ketone, acetone, etc. Examples include a method in which a hydrophilic organic solvent such as a ketone is added and the deodorizing active ingredient is thermally extracted 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 is used, for example, as it is, or after being diluted with a suitable solvent, concentrated, or concentrated to dryness. The deodorizing active ingredient and the extract may be used alone or in combination of two or more. 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 elute and remove aroma components such as grassy odor contained in the raw material plants in advance. Note that the aroma component can also be removed by steam distillation.

[0015] Deodorizing 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 an active deodorizing ingredient obtained from plants. There are no particular limitations on the plant essential oils that can be used, but examples include abyss 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 , cypress oil, etc. Only one type of plant essential oil may be used, or two or more types may be used in combination.

[0016] The content of the plant essential oil is not particularly limited, but for example, the content of the plant essential oil is 0.0001 to 0.
．． Preferably it is 1% by volume. 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. Further, if the content is below the lower limit of the above range, there is a possibility that the effect of offsetting the odor may not be exhibited.

[0017] If necessary, a fragrance may be included to further add aroma. As mentioned above, the deodorant of this invention needs to have a water content of 20% by weight or less based on the entire deodorant. This is because if the water content exceeds 20% by weight, corrosion of the spray can will increase.

The deodorant of the present invention is not particularly limited, but preferably contains glyoxal. This is because the effect of glyoxal strengthens the deodorizing power and provides stability over time. If glyoxal is included, its content is not particularly limited, but should be 0.1 to 500 parts by weight per 1 part by weight of the deodorizing active ingredient obtained from the plant (e.g., plant extract). is preferred.

The deodorant of the present invention is not particularly limited, but preferably contains a surfactant as a shaver cleaning agent. When a shaver is used, sebum, skin, beard residue, bacteria, etc. adhere to the shaver, and a bad odor is generated from these substances. When the deodorant of the present invention contains a surfactant, by washing the shaver with water after using this deodorant, not only will the bad odor disappear due to the effect of the deodorizing active ingredients obtained from plants, but also the odor will disappear. This is because the source of the bad odor is washed away by the cleaning effect of the surfactant, and as a result, the bad odor will not occur again. In addition, the sebum, skin, beard residue, etc. cause a decline in the functionality of the shaver, but surfactants are effective in terms of shaver maintenance because they can wash them off as mentioned above. This is because it also has a shaver foam effect.

[0020] The surfactants that can be used are not limited in any way as long as they provide a cleaning effect for the shaver, and include cationic surfactants, anionic surfactants, amphoteric surfactants, and nonionic surfactants. Either of these is fine. Also,
When the deodorant of this invention is sprayed onto a shaver, it is preferable that the deodorant becomes mousse-like (microbubble-like). This is because if it becomes mousse-like, the cleaning effect will be further enhanced due to the fine bubbles. Specific examples of surfactants that make it possible to form a mousse include, but are not particularly limited to, derivatives of polyethylene glycol, such as polyethylene glycol nonylphenyl ether and polyethylene glycol octylphenyl ether.

[0021] When a surfactant is included, its content is not particularly limited, but it is preferably 1 to 20% by weight based on the entire deodorant. Moreover, only one type of surfactant may be used, or two or more types may be used in combination. The deodorant of this 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. The effect of the antibacterial agent will kill the bacteria attached to the shaver, or
Alternatively, by preventing the proliferation, it is possible to prevent the bad odor generated from the bacterial cells and to extend the life of the deodorant. The antibacterial agents that can be used are not particularly limited, but those that are soluble in water, alcohols, or other organic solvents are preferred. Specific examples include, but are not particularly limited to, quaternary ammonium compounds such as benzalkonium chloride and cetylpyridinium chloride, sodium lauryl sulfate, and phenolic compounds such as isopropylmethylphenol and resorcinol. Among these, benzalkonium chloride, cetylpyridinium chloride, isopropylmethylphenol and the like are particularly preferred. Note that as the antibacterial agent, one that also serves as a surfactant may be used. Such antibacterial agents are not particularly limited, but include, for example, the aforementioned quaternary ammonium compounds (cationic surfactants) such as benzalkonium chloride and cetylpyridinium chloride, and sodium lauryl sulfate (anionic surfactants). ) etc.

[0023] When the deodorant contains an antibacterial agent, the content thereof is not particularly limited;
．． It is preferably 1 to 10 parts by weight. Antibacterial agents are 1
Only the seeds may be used, or two or more types may be used in combination. The deodorant of this invention may contain an organic solvent as a diluent, if necessary. Organic solvents that can be used are not particularly limited, but include, for example, alcohols such as methanol and ethanol, hydrophilic and hydrophobic organic solvents such as ketones such as methyl ethyl ketone and acetone, petroleum ether, hexane, and ethyl acetate. Examples include hydrophobic organic solvents such as. When an organic solvent is included, the content thereof is not particularly limited, but, for example, it is preferable that the organic solvent is 99 parts by volume or less per 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 safety, the pH of the deodorant should be from weakly acidic to weakly alkaline (for example, 50%
It is preferable to adjust it to about 8 to 8). 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.

The deodorant of the present invention is not particularly limited, but preferably contains liquid paraffin. If it contains liquid paraffin, spray the deodorant of this invention on the shaver after washing the shaver or after using the shaver to make the shaver smooth.
Moreover, it can be used in an odorless state. That is,
Contains liquid paraffin, which provides a lubricating effect.
This is because it is also effective in terms of shaver maintenance.

When liquid paraffin is contained, its content is not particularly limited, but it is preferably 5% by volume or more based on the entire contents of the spray can. Content is 5% by volume
This is because if it is less than that, the above-mentioned lubricating effect cannot be obtained sufficiently. When the deodorant of this invention contains liquid paraffin, it is preferable that it also contains hexane. In making the spray deodorant of this invention, liquid paraffin is typically poured into a spray can separately from other ingredients. that time,
Liquid paraffin is difficult to pour into a spray can as it is. Therefore, if liquid paraffin is diluted with hexane, it becomes easier to inject liquid paraffin into a spray can. The amount of hexane used when diluting liquid paraffin with hexane is not particularly limited, but
It is preferably about 0.5 to 2 parts by volume per 1 part by volume of liquid paraffin.

[0027] Spraying (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 the pressure of one or more propellants, or using the negative pressure of a fluid such as a mist sprayer. Examples include a type that uses pressure from outside the container, and a type that uses pressure from outside the container. In addition, when using a propellant, the amount used is not particularly limited, but
It is preferably about 20 to 80% by volume based on the entire contents of the spray can.

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

[0029]

[Effect] By containing deodorizing active ingredients obtained from plants, it becomes possible to effectively eliminate odors generated from shavers. In addition, the water content is increased by 2 to the entire deodorant.
If the content is kept below 0% by weight, corrosion of the spray can will be reduced.

[0030]

[Examples] Specific examples and comparative examples of the present invention are shown below, but the present invention is not limited to the following examples. -Examples 1 to 10- 60 for Osmanthus or Forsythia, respectively
Extraction was performed for about 3 hours with hot water at a temperature of 0.degree. C., and the resulting extract was concentrated to dryness using a rotary evaporator to obtain a plant extract (deodorizing active ingredient). Glyoxal, an antibacterial agent, and a plant essential oil are added to the obtained plant extract, and purified using an aqueous solution of potassium hydroxide or an aqueous solution of sodium hydroxide.
After adjusting H to 5-8, an organic solvent was added.

After pouring the obtained mixture into a spray can, liquid paraffin diluted with hexane was poured, and a propellant was sealed in the spray can.
A spray deodorant containing each component at the concentrations shown in 2 was obtained. The spray can used was an aluminum can coated with epoxy resin.

C1 and C2 in the propellant type column represent a DME-LPG mixed propellant and an LPG propellant, respectively. - Comparative Examples 1 to 10 - Examples 1 to 10 except that the deodorizing active ingredients obtained from plants (plant extracts and plant essential oils), glyoxal, and antibacterial agents were not included. 1
A spray deodorant was prepared in the same manner as in Example 0.

[0037] Above Examples 1 to 10 and Comparative Examples 1 to 1
The deodorizing effect of each deodorant obtained in Example 0 was investigated as follows. One shaver for the example and one shaver for the comparative example
After shaving half of the face with the shaver for the example, the remaining half of the face was shaved using the shaver for the comparative example. The deodorant of each example and comparative example was sprayed for 2 seconds onto the inner and outer blades of the used shaver of the example and the shaver of the comparative example, and then left at room temperature for 24 hours.

[0038] Thereafter, 10 panelists with the same sense of smell were asked to smell the shaver, and an odor intensity sensory test and a pleasure/displeasure sensory test were conducted simultaneously. The odor intensity was evaluated on a six-level scale of 0, 1, 2, 3, 4, and 5. Odor intensity 0 is ``no odor'', 1 is ``a barely perceptible odor'', 2 is ``a smell that you can tell what it is'', 3
4 is a "strong smell", 5 is a "smell that can be easily detected", 5 is a "strong smell"
means "strong odor".

[0039] Also, the degree of pleasure and displeasure is +4, +3, +2, +
Evaluation was made using nine levels of numerical values: 1, 0, -1, -2, -3, -4. Pleasure/displeasure level +4 is "extremely pleasant", +3 is "very pleasant", +2 is "pleasant", +1 is "somewhat pleasant", 0 is "neither pleasant nor unpleasant", -1 is "slightly unpleasant", -2 is “uncomfortable”;
-3 means "very uncomfortable" and -4 means "extremely uncomfortable."

The results are shown in Table 3 below. In addition,
The results shown in Table 3 are the average values of the 10 panelists. Additionally, if a shaver is left untreated at room temperature for 24 hours, the odor intensity will be 3.
．． 0, and the pleasure/displeasure level was -3.5.

[0041]

[Table 3]

[0042] As shown in Table 3, the deodorants obtained in Examples 1 to 10 have superior deodorizing effects and are less reactive than the deodorants obtained in Comparative Examples 1 to 10. It was confirmed that the odor after use was not unpleasant. In addition, the influence of the water content of the deodorant on the corrosion of spray cans was investigated as follows.

Three comparative deodorants having water contents of 30% by weight, 50% by weight, and 60% by weight, respectively, were prepared in the same manner as in the previous example. However, as a propellant,
DME or LPG was used. These deodorants and the deodorants obtained in Examples 5, 7, and 8 (water contents of 0%, 10%, and 20% by weight, respectively) were mixed at 60°C for 1 hour.
After standing for 0 days, corrosion inside the can was visually evaluated. The evaluation was conducted in accordance with the following.

◯: No corrosion was observed. △...Almost no corrosion was observed. ×...Corrosion was observed. As a result, deodorants with water content of 0% and 10% by weight are ○
The deodorants with a water content of 20% by weight were rated ○ to △, while the comparison deodorants with a water content of 30%, 50%, and 60% by weight were all rated ×. there were.

[0045] From this, it was confirmed that corrosion of spray cans can be suppressed by suppressing the water content of the deodorant to 20% by weight or less.

[0046]

Effects of the Invention The spray deodorant for shavers according to the present invention contains deodorizing active ingredients obtained from plants, so it eliminates odors that occur after using a shaver, especially sweat odor and body odor, or those that stick to the shaver. It can exhibit a high deodorizing effect against bad odors generated from sebum, skin, beard residue, bacterial cells, etc.

[0047] Furthermore, since the water content of this deodorant is 20% by weight or less based on the entire deodorant, corrosion of the spray can can be reduced.
