Description

  The present invention relates to a bath agent, and more particularly, to a bath agent having an excellent warm bath effect using a plant belonging to the genus Firaceae.

  Conventionally, various bath preparations aimed at improving the warm bath effect have been proposed. For example, inorganic salts such as sodium sulfate and sodium carbonate prevent heat dissipation to increase the heat retention effect after bathing, or carbonate and organic acids are mixed to generate carbon dioxide in bath water, which causes blood circulation by its vasodilatory action. Effervescent bath agents that promote water resistance have been developed. The use of natural plants in bath preparations has also been studied. For example, herbal medicines such as carrots are known as ingredients that can be blended in foaming bath preparations (see Patent Documents 1 and 2). It is said that the fermentable bath preparation synergistically enhances the blood circulation promoting effect and the moisturizing effect of the skin after hot water (see Patent Document 3). Moreover, the bath preparation which provided the pain relieving effect by using the extract obtained from the cypress plant is also developed (patent document 4).

  On the other hand, due to lack of successors and falling timber prices, the forests are poorly maintained, and their devastation is a major problem. The maintenance of this forest is mainly thinning and pruning, but if there is no economic value for the thinned wood and the branches and leaves that were dropped by pruning, and it only costs money, this kind of maintenance is neglected. It is natural to become. Therefore, in order to promote the maintenance of the forest, it has been desired to develop a processing method and a new application for converting the trees to be thinned or pruned into effective resources.

  The present inventors examined a method of heat treatment by microwave irradiation under reduced pressure as a method of effectively utilizing the branches and leaves of such a tree to be felled, and the obtained distillate was used as a fragrance or nitrogen dioxide. It has been reported that it can be used as a harmful oxide remover such as (Patent Documents 5 and 6).

Japanese Patent Laid-Open No. 62-234015 JP-A-7-546 JP-A-60-215618 Japanese Patent Laid-Open No. 11-158058 JP 2011-174021 A Republished patent WO2010 / 98439

  This invention makes it a subject to provide the bath agent which is excellent in the warm bath effect using the tree thinned and pruned.

  As a result of intensive studies to achieve the above-mentioned problems, the present inventors have obtained an excellent warm bath effect by adding an extract or a distillate obtained from a tree of the genus Piraceae to the bath water. The present invention has been found.

  That is, the present invention is a bath preparation containing a pressed solution, an extract or a distillate of a plant belonging to the genus Piraceae.

  The bath agent of the present invention has a high warm bath effect, is excellent in a heat retaining effect after bathing, and can obtain a relaxing effect and a stress relieving effect, and has an excellent effect in preventing hot water cooling and improving cooling.

It is a figure which shows typically the structure of the microwave distillation apparatus used in order to obtain the distillate of the plant which belongs to the pine family Fir genus used for the bath agent of this invention. In Example 1, it is a graph which shows the temperature fall of the skin temperature of the first foot dorsal part during a foot bath implementation period (Yes; Todomatsu vacuum steam distilled aqueous fraction used in Production Example 1, no; only hot water). In Example 1, it is a graph which shows the temperature fall of the skin temperature of the foot back part after 1 week continuation during a footbath implementation period (Yes; Todomatsu vacuum steam distilled aqueous fraction used in Production Example 1; No; Only hot water).

  The bath agent of the present invention contains a juice, extract or distillate of a plant belonging to the genus Firaceae as an active ingredient.

  Examples of plants belonging to the genus Firaceae include Todomatsu, Fir, Virgin Fir, Silaviso, Greater Silvia, Silabe, Balsam Fir, White Fir, White Fir, Amabilis Fur, Aoto Domatsu, California Red Fur, Grand Fur, Noble Fur, etc. However, among these, Todomatsu is preferably used.

  As a raw material of the bath agent of the present invention, all or a part of the plant belonging to the genus Firaceae (for example, fruit, seed, leaf, bark, rhizome, flower, etc.) is used. Of these, the leaf portion is preferably used from the viewpoint of effective utilization of trees that are thinned and pruned. The leaf portion may be used as it is, but is preferably used after being pulverized and crushed by a pulverizer or a crusher.

  A juice, an extract or a distillate is obtained from the whole plant or a part of the plant belonging to the genus Piraceae. Manufacture of squeezed liquid can be performed using a well-known pressing machine. The extract can also be produced according to a conventional method, but the extraction solvent is preferably a polar solvent, specifically, an alcohol solvent such as water, ethanol, methanol, butyl alcohol, ethylene glycol, propylene glycol, glycerin and the like. A halogen-containing solvent such as chloroform; an ether solvent such as dioxane; a carbonyl solvent such as acetone and ethyl acetate; and a mixture thereof. The distillate can be obtained by atmospheric distillation, vacuum distillation, steam distillation or the like.

  Of these, distillates are preferred, and those obtained by distillation under reduced pressure are particularly preferred. The heating may be performed by a heater, but microwave heating is preferable, and it is particularly preferable to irradiate the microwave only with water originally contained in the plant body without adding water. By irradiating microwaves, water molecules contained in plants are directly heated to generate water vapor, which acts as a mobile phase and distills volatile components in the plants. It is considered to include a vacuum distillation element depending on the boiling point of the component and a steam distillation element. Such a distillate can be obtained, for example, by using the apparatus shown in FIG. In the figure, 1 is a microwave distillation apparatus, 2 is a distillation tank, 3 is a microwave heating apparatus, 4 is a stirring splash, 5 is an airflow inflow pipe, 6 is a distillate outflow pipe, 7 is a cooling apparatus, and 8 is heating control. Device, 9 is a pressure reducing pump, 10 is a pressure regulating valve, 11 is a pressure control device, 12 is an object to be distilled, and 13 is a distillate.

  In this apparatus 1, a plant belonging to the genus Pinaceae, which is a raw material to be distilled 12, is placed in a distillation tank 2, and stirred with a stirring splash 4, and a microwave heating apparatus provided on the upper surface of the distillation tank 2. The microwave is radiated from 3 to heat the raw material. The distillation tank 2 communicates with the air flow inlet 5 and the distillate outflow pipe 6. The airflow inlet pipe 5 introduces an inert gas such as air or nitrogen gas into the reaction tank 2, and this airflow is introduced from the lower part of the reaction tank 2. The distillate outflow pipe 6 leads the distillate from the raw material to the outside from the upper part of the reaction tank 2.

  The temperature and pressure of the inside of the reaction tank 2 are measured by a temperature sensor and a pressure sensor (both not shown) attached to the reaction tank 2, and a heating control device 8, a pressure control device 11, and a pressure adjusting valve are measured. 10 are adjusted respectively.

  The gaseous distillate flowing out from the distillation tank 2 through the distillate outflow pipe 6 is replaced with a liquid by the cooling device 7 and obtained as a distillate 13. The distillate 13 includes an oily fraction 13a and an aqueous fraction 13b. Of these, the aqueous fraction 13b is preferably used. Since the aqueous fraction 13b has high solubility in water, it can be added to bath water as it is without using a surfactant or the like, and it can also be added in a large amount. Furthermore, since the aqueous fraction 13b does not contain a heavy scent and has a refreshing fragrance, it can contribute to the comfort and relaxation of the fragrance.

  In distillation, the pressure in the distillation tank 2 may be 3 to 95 kilopascals, preferably 3 to 40 kilopascals, more preferably 3 to 25 kilopascals, and the steam temperature at that time is 40 ° C. To 100 ° C. When the pressure is 3 kilopascals or less, the increase in vapor pressure of volatile components in the plant is suppressed, and the vacuum distillation component due to the boiling point of each component is the main component from the steam distillation component. Therefore, it is not preferable in that extraction of a component having a boiling point higher than that of water is not efficiently performed. Moreover, since the temperature of a raw material becomes high at 95 kilopascals or more, it is not preferable at the point that an energy loss is large and oxidation of a raw material will be accelerated | stimulated. The distillation time may be about 0.2 to 8 hours, preferably about 0.4 to 6 hours. If it is 0.2 hours or less, a large amount of unextracted components remain in the plant, and if it is 8 hours or more, the raw material becomes nearly dry, which is not preferable in that the extraction efficiency decreases.

  Furthermore, the gas introduced into the distillation tank 2 may be air, but an inert gas such as nitrogen gas, helium gas, or argon gas is preferable, and the flow rate per minute is the distillation tank 2. It may be about 0.001 to 0.1 times the capacity.

  The juice, extract or distillate of the plant belonging to the genus Firaceae obtained as described above can be used as it is for the bath preparation of the present invention, but if necessary, further concentrated by a conventional method. Or may be purified.

  EXAMPLES Next, although an Example etc. are given and this invention is demonstrated in more detail, this invention is not restrict | limited at all by these Examples.

Manufacturing example 1
About 50 kg of Todomatsu leaves pulverized with a crushing crusher (manufactured by KYB Seisakusho) is put into the distillation tank of the microwave steam distillation apparatus shown in FIG. 1, and the pressure in the distillation tank is about 20 KPa while stirring. The mixture was kept under reduced pressure (vapor temperature was about 67 ° C.) and distilled by microwave irradiation for 1 hour. An aqueous fraction was collected from the obtained distillate to obtain a Todomatsu vacuum steam distilled aqueous fraction.

Example 1
Hot bath effect:
The warm bath effect of the Todomatsu vacuum steam-distilled aqueous fraction obtained in Production Example 1 was confirmed. Divide 10 subjects into two groups, A and B (Group A: 3 men, 2 women, Group B: 2 men, 3 women; average age 25.4 years (23-29 years), average BMI 20.8 (18.1 to 23.0)), a week-out washout period was set, foot baths were performed at home for one week continuously, and the foot baths were performed again for one week with the conditions crossed over. The foot bath was performed from 1 hour after the last meal of the day to 1 hour before going to bed, at a water temperature of 41 ° C. for 10 minutes before taking a shower. As the foot bath device, a commercially available foamed resin foot bath (trade name: Foot Bath Pro, width 35 cm × depth 35 cm × height 30 cm) was used. The bath water used for foot bath was obtained by adding 0.4 L of the Todomatsu vacuum steam distilled aqueous fraction obtained in Production Example 1 to 9 L of hot water. During the washout period, foot bathing was not performed, bathing in the bathtub was not allowed, and only shower bathing was allowed.
During the foot bathing period, the skin temperature at the back of the foot was measured for the first time and after 1 week. The measurement was performed four times before and after foot bathing, with the indoor environment set at room temperature 25-26 ° C. and humidity 50-60%, once each day and one week later. Body temperature logger LT8A (Gram Corporation) was used to measure skin temperature, and the sensor was taped to the back of the right foot and covered with waterproof dressing tape and measured every 5 seconds. As a foot bath device during measurement, Mr. Kojiri (Kyoyo Co., Ltd .; Model FB-C80) with an automatic heat retaining device was used.
As a general rule, the measurement period was 09: 00-11: 00 or 13: 00-16: 00, and was standardized for each subject. The skin temperature 5 seconds after the end of the foot bath was set to the reference value 0, and then the temperature decrease value for 14 minutes was calculated and plotted. As a control, the same measurement was performed using 9 L of hot water only. Statistical analysis add-in software Excel Statistics 2012 for Windows was used for statistical processing, and p-values less than 0.05 were considered statistically significant. To compare changes in skin temperature over time between the two groups, a corresponding two-way analysis of variance was performed, and when a significant difference was observed, an analysis was performed for each time by the Bonferroni method. The results are shown in FIGS. 2 and 3 (* p <0.05, ** p <0.01).

In the foot bath on the first day, when Todomatsu steam-distilled aqueous fraction was added, the decrease in skin temperature was significantly smaller (p <0.0001) compared to hot water alone, especially from 30 seconds to 2 minutes and 30 seconds after foot bath, A significant difference was observed between 3 minutes 30 seconds and 6 minutes 30 seconds to 14 minutes (FIG. 2).
In addition, even after one week of foot bathing, the skin temperature lowering value at the back of the foot was significantly less when the todomatsu vacuum steam distilled aqueous fraction was added (p <0.0001), especially with foot bath. There was a significant difference from the third minute to 13 minutes after the completion (FIG. 3).

Example 2
Mood state:
The relaxing effect and the like by the Todomatsu vacuum steam distilled aqueous fraction obtained in Production Example 1 were confirmed. In the same manner as in Example 1, the test subjects were divided into 5 groups of 5 males and 2 females, and foot baths were carried out at home for one week continuously. After one week of washout, the conditions were crossed over and the foot baths were performed again for one week. The subject's mood state was evaluated after 1 week of foot bathing.
For evaluation of mood state, standardized questionnaire Mood Check List-Short Form 2 (MCL-S.2), which can be easily and frequently measured, was used to judge pleasant feelings, relaxation, and anxiety (Kunio Hashimoto, Murakami) Masahiko: Reliability and validity of the revised positive emotion scale (MCL-S.2) associated with exercise, Health Science 33: 21-26, 2011). The MCL-S.2 Question Sheet consists of 4 items for each index, a total of 12 items, and the responses were evaluated in seven ways, from “Yes at all” to “No at all”. After resting on the chair for 5 minutes, I was asked to fill in the MCL-S.2 question sheet. Statistical analysis add-in software Excel Statistics 2012 for Windows was used for statistical processing, and p-values less than 0.05 were considered statistically significant. A t-test (Welch's method) was performed for changes in the mood index. The results are shown in Table 1.

  By continuing foot bathing for 1 week, the pleasant feeling increased significantly (p <0.05) on the last day, and the relaxation tended to increase (p <0.1).
