Description

The present invention relates to deodorants.

In recent years, odors generated from animals including humans, odors generated from indoors, cars, refrigerators, toilets, livestock barns, fish tanks, or factories, household waste, industrial waste, etc. have been deodorized or eliminated. Deodorants are commercially available for odors. As such a deodorant, it is desirable to use a deodorant using a naturally-derived component in consideration of the environment after use. For example, Patent Document 1 discloses a deodorant containing a distillate derived from cane as an active ingredient.

JP-A-2001-87365

The cane-derived distillate contained in the deodorant described in Patent Document 1 contains ethanol and water. On the other hand, when the deodorant is blended as a deodorizing raw material such as an oily perfume, it is desirable not to contain water. In addition, when the deodorant is oil-soluble, it is likely to remain on deodorizing objects such as cloth, and it is possible to develop applications for deodorants with excellent deodorizing (deodorizing) effects. From such a point of view, there is a demand for a deodorant that has a deodorant effect and is oil-soluble.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an oil-soluble deodorant having a deodorizing effect.

The cane-derived distillate may be a distillate of a raw material selected from the group consisting of sugar cane juice and a solvent extract of cane, and a distillate of a raw material selected from the group consisting of sugar cane juice and a solvent extract of cane. is passed through a column packed with a synthetic adsorbent as a stationary carrier, and the adsorbed component adsorbed on the synthetic adsorbent is eluted with an elution solvent selected from the group consisting of water, methanol, ethanol and mixtures thereof. It may be an eluate obtained by elution. In this case, the effect of the present invention becomes even more excellent.

The oil-soluble solvent may be at least one selected from the group consisting of triethyl citrate, dipropylene glycol, refined animal and vegetable oils, essential oils, glycerin, diethylene glycol monobutyl ether, triacetin and 1,3-butanediol. It is preferably at least one selected from the group consisting of citrate and dipropylene glycol. In this case, the effect of the present invention becomes even more excellent.

According to the present invention, it is possible to provide an oil-soluble deodorant while having a deodorizing effect.

DETAILED DESCRIPTION OF THE INVENTION Embodiments for carrying out the present invention will be described in detail below. In addition, this invention is not limited to the following embodiment.

The "deodorant" in the present specification contains an ingredient (active ingredient) having a deodorant effect and an oil-soluble solvent. Moreover, the deodorant of this embodiment may be compatible with water. The deodorant may exhibit a deodorizing effect by eliminating or suppressing the odor of the object to be deodorized, and exhibits the deodorizing effect by masking the odor of the object to be deodorized. It may be a substance (masking agent).

The deodorant of the present embodiment contains a concentrate of a liquid mixture of a distillate derived from cane (distilled product) and an oil-soluble solvent.

The distillate derived from sugar cane can be obtained by distilling a raw material obtained from sugar cane (hereinafter simply referred to as "raw material derived from sugar cane" or "raw material"). Raw materials derived from cane include, for example, cane juice, cane solvent extract, and the like. Cane juice includes pressed juice obtained by squeezing cane, infused juice obtained by leaching cane with water, or clean and concentrated juices that have been limed in a raw sugar manufacturing plant. The solvent extract of sugarcane means an extract obtained by extracting sugarcane with an extraction solvent. The extraction solvent may contain an organic solvent, and may be, for example, an alcohol solvent such as methanol or ethanol, or a mixed solvent of the alcohol and water. The extraction solvent may be used alone or in combination of two or more.

In the deodorant of the present embodiment, the distillate derived from cane is preferably a distillate of at least one selected from the group consisting of sugar cane juice and a solvent extract of cane ("raw material derived from cane").

The cane-derived distillate is obtained, for example, by distilling a cane-derived raw material under the following conditions.

Distillation treatment is performed by putting raw materials into a tank of a distillation apparatus equipped with a heating device, heating the tank, and recovering vapor generated from the raw materials. By distilling, the vapor containing the distillate derived from the cane is recovered as a gas, preferably as a liquid, and separated from the non-vaporized solids.

The temperature (vapor temperature or product temperature) condition for the distillation treatment is preferably 50 to 120°C, more preferably 80 to 120°C, even more preferably 85 to 120°C. The pressure conditions for the distillation treatment are preferably 240 to 1450 mmHg, more preferably 450 to 1450 mmHg. The pressure conditions for the distillation treatment may be adjusted according to the composition of the raw material so that the raw material boils under desired temperature conditions.

Distillation treatment can be carried out under pressure conditions of either increased pressure or reduced pressure based on atmospheric pressure (760 mmHg). The distillation process may be carried out at a pressure between 50° C. and 120° C. at which the distillation feedstock liquid boils. The distillation process may preferably be carried out at a pressure between 70°C and 120°C at which the distillation feed liquid boils. For example, suitable conditions for distilling cane juice under pressure are a pressure of 980 to 1425 mmHg and a temperature of 110 to 118°C. On the other hand, suitable conditions for distillation of cane juice under reduced pressure or atmospheric pressure are a pressure of 460-760 mmHg and a temperature of 87-100°C.

Incidentally, the conditions for the distillation treatment may be appropriately adjusted according to the type and ratio of the solvent contained in the raw material, the apparatus used for the distillation treatment, and the like. For example, when using a solvent extract of sugar cane using water as an extraction solvent as a raw material, and using a centrifugal thin film vacuum evaporator, a flask connected to a cooling tube, or a distiller as a distillation apparatus, suitable distillation conditions are The temperature is 70 to 105° C. and the pressure is 240 to 760 mmHg. Distillation treatment under conditions of a temperature of less than 70°C and/or a pressure of less than 240 mmHg is applicable for experimental small-scale cases, but is not applicable for large-scale cases from the viewpoint of the cost and workability of the distillation apparatus. is common.

A general distillation apparatus or evaporator can be used for the distillation treatment. In other words, it is sufficient to have a heating device that can accommodate the raw material and heats the raw material, a cooling device that cools the steam generated by heating, and a recovery device that recovers the cooled steam as a liquid or gas. . As a distillation apparatus, for example, a flask equipped with a cooling tube is used in a laboratory, and an apparatus equipped with a concentrator, a crystallizer, an effector, etc. is used in a factory.

By adjusting the temperature and pressure conditions of the distillation treatment, the active ingredient in the raw material can be concentrated to obtain a distillate (distillate) containing the active ingredient at a desired concentration.

The cane-derived distillate (distilled liquid) in the deodorant of the present embodiment may be one subjected to column chromatography treatment (column treatment). That is, the distillate derived from sugar cane is obtained by passing a raw material distillate selected from the group consisting of sugar cane juice and a solvent extract of sugar cane through a column filled with a synthetic adsorbent as a fixed carrier, thereby obtaining a synthetic adsorbent. It may be an eluate obtained by eluting the adsorbed component adsorbed to the eluate with an elution solvent selected from the group consisting of water, methanol, ethanol and mixtures thereof. The column treatment further concentrates the active ingredients contained in the distillate obtained in the distillation treatment.

Suitable conditions and methods (synthetic adsorbent to be used, flow rate, etc.) for the column chromatography treatment of the distillate (distillate) are, for example, as follows.

Synthetic adsorbents (porous adsorbents) packed in the column include aromatic resins (for example, unsubstituted aromatic resins), acrylic acid-based methacrylic resins, acrylonitrile aliphatic resins, and the like. The synthetic adsorbent may be at least one selected from the group consisting of aromatic resins, acrylic methacrylic resins and acrylonitrile aliphatic resins, and unsubstituted aromatic resins or acrylic ester resins. is preferred. Such synthetic adsorbents are commercially available. Aromatic resins, all trade names, manufactured by Mitsubishi Chemical Corporation); SP-825, SP-800, SP-850, SP-875, SP-70, SP-700 Treated aromatic resin, both trade names, manufactured by Mitsubishi Chemical Corporation); SP-900 (aromatic resin, trade name, manufactured by Mitsubishi Chemical Corporation); Amberlite (trademark) as XAD-2 , XAD-4, XAD-16, XAD-2000 (above, aromatic resins, all trade names, manufactured by Organo Co., Ltd.); (Aromatic resins having hydrophobic substituents, both trade names, manufactured by Mitsubishi Chemical Corporation); HP-2MG, EX-0021 (Aromatic resins having hydrophobic substituents, both commercial name, manufactured by Mitsubishi Chemical Corporation); XAD-7HP and XAD-8 as Amberlite (trademark) series (acrylic ester resins, both trade names, manufactured by Organo Co., Ltd.); Diaion (trademark) series As HP1MG, HP2MG (above, acrylic acid-based methacrylic resins, both trade names, manufactured by Mitsubishi Chemical Corporation); Sephadex (trademark) LH20, LH60 (above, crosslinked dextran derivatives, both trade names, Pharmacia Biotech Co., Ltd.) and the like. Since the type of synthetic adsorbent that is suitable for the concentration of the substance to be passed through, the solvent, the extraction method, the coexisting substances, etc. differs, it is possible to make an appropriate selection.

The amount of the synthetic adsorbent to be packed in the column may be appropriately determined according to the size of the column, the type of solvent, the type of synthetic adsorbent, and the like. For example, when a liquid raw material is subjected to column treatment, the amount of distillate to be passed through the column is generally 1.5 to 20,000 parts by volume when the amount of synthetic adsorbent in the column is 1 part by volume. That is, it is preferable to fill the column with the synthetic adsorbent in a wet volume amount of 1/20000 to 1/1.5 of the feed amount of the raw material.

A distillate obtained by distillation is passed through the column packed with the synthetic adsorbent. The distillate itself may be passed through the column, or a diluted solution diluted with water may be passed through the column to adjust the alcohol concentration. At this time, the column temperature is preferably within the range of 60 to 97°C. After completion of passing the liquid through the column, water may be passed through the column to wash the inside of the column with water. The alcohol concentration of the diluent may preferably be 10% by volume or less, or 5% by volume or less from the viewpoint of obtaining the desired component more efficiently. The alcohol concentration of the diluent may be greater than 0% by volume.

Next, the adsorbed component adsorbed on the synthetic adsorbent is eluted with an elution solvent to obtain an eluate. The elution solvent may be selected from, for example, water, methanol, ethanol, and mixtures thereof, and an ethanol-water mixed solvent with a mixing volume ratio (ethanol/water) of 50/50 to 99.5/0.5. There may be. At this time, the column temperature is preferably 20 to 40°C. After starting elution with an ethanol-water mixed solvent, elution is continued until the volume of the collected eluate reaches a predetermined volume. For example, assuming that the wet volume of the filled synthetic adsorbent is 1 part by volume, the recovery of the eluate is terminated when the volume of the recovered solution reaches 6 parts by volume. The elution rate is not particularly limited because it varies depending on the size of the column, the type of solvent, the type of immobilizing carrier, etc., but the elution rate may be SV=0.1-10. Here, SV (Space Velocity) is a unit indicating how many times the resin volume of liquid is passed per hour.

Column chromatography treatment is not limited to this, but preferably can be carried out as follows. That is, after passing the object to be passed through a column filled with an unsubstituted aromatic resin or acrylic acid ester resin at a column temperature of 60 to 97 ° C., the inside of the column is washed with water, and then the column is The adsorbed components are eluted with a 50/50-99.5/0.5 (volume/volume) ethanol-water mixed solvent at a column temperature of 20-40°C, and the elution start point with the ethanol-water mixed solvent. Collect the eluate (including elution solvent) in which the volume of eluate collected from the resin elutes within 6 times the wet volume of the resin. The obtained eluate (including the elution solvent) may be used as it is as a distillate derived from cane.

The oil-soluble solvent used herein means an organic solvent other than water, and may be a solvent compatible with water. The boiling point of the oil-soluble solvent is preferably 170°C or higher (more preferably 190°C or higher). Examples of oil-soluble solvents include triethyl citrate (triethyl citrate, TEC), dipropylene glycol (DPG), refined animal and vegetable oils, essential oils, glycerin, diethylene glycol monobutyl ether, triacetin and 1,3-butanediol. . The oil-soluble solvent may be at least one selected from the group consisting of triethylcitrate, dipropylene glycol, refined animal and vegetable oils, essential oils, glycerin, diethylene glycol monobutyl ether, triacetin and 1,3-butanediol. It is preferably at least one selected from the group consisting of latex and dipropylene glycol. By using the above-described oil-soluble solvent, it is possible to provide an oil-soluble deodorant while maintaining the deodorant effect.

Here, the content mass ratio (C ₂ /C ₁ ) of the oil-soluble solvent (C ₂ ) to the sugar cane-derived distillate (C 1 ) in the mixture is 1/1 to 10/1 (preferably ₁ /1 to 5/1). By subjecting the resulting mixture to a concentration treatment, a concentrate of the mixture is obtained.

The concentration treatment of the mixed liquid is preferably carried out under reduced pressure conditions with atmospheric pressure (760 mmHg) as the standard. For example, the temperature condition for the concentration treatment is preferably 50 to 90°C, more preferably 70 to 90°C. The pressure conditions for the concentration process may be 530 mmHg or less, or 230 mmHg or less. The pressure conditions for the concentration process may be adjusted according to the composition of the liquid mixture so that the liquid mixture boils under desired temperature conditions. The concentration process is completed when, for example, 1 part by mass of a distillate derived from cane and 3 parts by mass of an oil-soluble solvent are mixed and the concentrate (concentrated residue) obtained by the concentration process reaches 3 parts by mass. you can Note that the concentration treatment may be performed using an evaporator or the like.
