DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an essential oil solution which can be used by spraying it onto fibers or the like to facilitate the daily use of the essential oil as aromatherapy.

[0002]

BACKGROUND ART Aromatherapy (aromather)
apy) is a compound word for aroma for aroma and therapy for therapy. It is said to have a root in ancient Egypt as one of the treatments to cure mental and physical disorders using the relationship between smell and physiology. In Japan during the Nara period, chara and charcoal smoke were used for medicinal purposes. This has been a sign of an explosive boom several years ago, and full-scale research has been underway for more than ten years. The scent is converted into electric pulses by the olfactory cells in the nasal cavity, suppressing the excitement of the limbic nerves, awakening the paralyzed nervous system, and even drifting the aroma to the air conditioning of all apartments.

[0003] At the Seirei Mikatahara Hospital in Shizuoka Prefecture, known for its hospice, the comfort of patients housed in a Japanese-style rehabilitation room with aroma of wood and tatami mats was compared with that in a normal sickroom. It was confirmed that the target stress was less than half that in a general hospital room, and that the work ability was also improved. In particular, the scent of trees increases peripheral blood flow and reduces stress hormone levels. By the way, there are orange, lemon, vermouth, lavender, rosemary, peppermint and the like as scents having an analgesic effect. The oily substances extracted from these are called essential oils (essential oils).

[0004] In the 1920s, French scientist Gatfosse studied the essential oils in depth, and it is said that he first used the expression aromatherapy. The essential oil components are absorbed through mucous membranes and work directly on the central part of the brain to relax and activate the mind and body. In particular,
There are known methods of volatilizing essential oils in a censer, using them for massage and bath oil, and blending them into packs and lotions. In addition, since the essential oil has a soothing effect, a deodorant effect, and a relaxing effect on the mind and body, attempts have been made by dentists to evaporate this using an evaporating dish to fill the space where the patient is present and use it. I have.

[0005]

However, the conventional method of use is to use as a bathing agent or to use an evaporating dish as used by a dentist, so that it cannot be easily used when it comes to mind. Essential oils are generally vaporized and used using candles or electric burners. It vaporizes even at normal temperatures, but the diffusion speed is considerably reduced. As described above, a variety of devices have been required to use the aroma effect of essential oils, and the place of use has been limited. In order to be easily used when one thinks, it is only necessary to spray the essential oil liquid and spray it on the target using a spray gun or the like, but such use has not been developed. As mentioned above, the use of essential oils is increasing, but some are relatively expensive, so that not everyone can use them as described above. SUMMARY OF THE INVENTION An object of the present invention is to provide an essential oil liquid in which a small amount of an essential oil is encapsulated and stored in a diluted state, and the liquid can be used as a mist (microcapsule spray) when necessary. Is to provide.

[0006]

According to the present invention, there is provided an essential oil solution which can be sprayed or applied by applying a binder to a slurry obtained by encapsulating an essential oil in a microcapsule, diluting the solvent with a solvent, and then diluting the fiber with a solvent. It is configured to be available for spraying. The microcapsules of the essential oil may be non-perforated capsules, perforated capsules, or a mixture thereof. A plurality of types of essential oils can be used as the essential oil, and the mixing ratio can be changed according to the purpose. Examples of the fibers include non-woven fabrics and cloths, such as clothes, futons, cloths for tour goods, and insoles of shoes. In addition, you may spray directly on hair etc.

[0007]

[Function] If the essential oil capsule which is microencapsulated and adhered to the fiber or the like with an aqueous binder is a non-porous capsule, the microcapsule is destroyed by a slight movement of the fiber or the like, and is vaporized and suspended in the atmosphere, thereby causing a human being. It adheres to the oral cavity, nostrils and trachea and is absorbed, exerting the effect of aromatherapy. If the essential oil capsule which is microencapsulated and adhered to the fibers and the like with an aqueous binder is a perforated capsule, the pores of the capsule are closed with the aqueous binder, so the fibers do not smell at first, but the fibers and the like are washed with water (washing). ), The aqueous binder is melted and the microcapsules are perforated, and fragrance is generated from that point. Depending on the intended use or the combination of perforated capsules or non-perforated capsules can be used selectively or in combination, and even by changing the type of each essential oil, it exerts the effects of various types of aromatherapy be able to.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The raw material of the essential oil liquid according to the present invention is, in this embodiment, microcapsules of a slurry-like essential oil, an aqueous binder, and water. It changes depending on the type of fiber. Those that are relatively familiar as essential oils are lavender, geranium, frankincen, petitgren, inline, basil, marjoram, cypress, straight orange,
Peppermint, rosemary, grapefruit, lime, lemon and the like. For example, when an emotional stabilizing effect is desired as a therapeutic effect of essential oil, lavender, geranium, and frankincen are used in a 6: 1: 2 volume ratio.
Used in When a sedative effect is desired, lavender, petitgrain, and inline are used in a volume ratio of 6: 2: 2.

A microcapsule is a micro container having a size of several microns, and as a material for the capsule film, there are a variety of natural polymers such as gelatin and gum arabic, and synthetic polymers such as polyvinyl alcohol and nylon. The microcapsules include a perforated capsule having fine pores on the surface and a non-porous capsule having no pores on the surface. In the case of a non-porous capsule in which an essential oil is encapsulated, a film is broken by the application of a physical force from the outside and a fragrance is generated. In the case of a perforated capsule encapsulating an essential oil, fragrance can be generated even if the capsule itself is not destroyed by an external force.However, when mixed with an aqueous binder, the aqueous binder seals the fine pores. Unless the aqueous binder is removed, no fragrance can be generated.

The type of encapsulation of the essential oil, the slurry in which the essential oil is encapsulated and the volume ratio of the water-soluble binder and water are selected mainly depending on the purpose of use. The same applies to the amount of microcapsule spray.

(Use for clothes and personal belongings) In the case of clothes and personal belongings such as handkerchiefs, the volume ratio is microcapsule: aqueous binder: water 1: 0.1 to 1: 1.
The water content is relatively large as 30 to 70. If the essential oil is applied to the nonwoven fabric of the dentist's clothes, the effect of relaxing the patient can be expected by smelling each time the dentist moves.

(Utilization of effects such as deodorization and sterilization used for insole of shoe) Deodorization and sterilization for a relatively long time by spraying the spray of the microcapsule using nonwoven fabric or the like on the insole (insole) of shoe In order to obtain the effect, it is necessary to further reduce the amount of water and increase the ratio of the slurry. Since the nonwoven fabric has many gaps, many microcapsules can be put between them. In this case, it is preferable to use non-porous microcapsules. By applying microcapsules that blend essential oils with deodorant effect, germicidal essential oils, refreshing essential oils, and essential oils that heal muscle fatigue to non-closed spaces such as nonwoven fabrics and fabrics Each step, the microcapsules are destroyed and the essential oil is released into the shoe. A dynamic force is applied to the insole every time you walk, emitting fragrance. Until now, insoles were made using activated carbon or chemicals, and mainly focused on chemical decomposition of odors based on adsorption. ADVANTAGE OF THE INVENTION According to this invention, the odor inside shoes (between toes, inside socks, inside shoes) is positively deodorized by the movement of feet.

(Use for Stuffed Toys and Dolls) The microcapsule liquid is applied to a stuffed toy or a doll inside or on the surface of the doll. When a doll or the like is hugged, the microcapsules are destroyed by that force and the essential oil is volatilized, producing an aroma effect (relaxation, sleep, and energy).

(Use of Essential Oil Microcapsules in Bedding, Sleeping Insect Repellent Effect) As a simple method of application, the liquid according to the present invention is applied or sprayed on a part of the fabric of an eye mask to slightly move the mouth and nose. As a result, the effect of the essential oil (aroma effect) is generated by breaking the microcapsules, thereby enabling a relaxing sleep. A microencapsulated liquid of an essential oil having a sleeping effect (mental stabilizing effect) is blended and applied to a non-woven fabric sheet or various fabrics. The microcapsules are destroyed according to the movement during sleep, and a scent with a sleep effect rises, promoting a more relaxed sleep. If you change the seat according to your mood, you can sleep well with your favorite scent. In addition, by applying microcapsules to the dough in the pillow, a pillow with a desired scent can be selected. Apply the microcapsules to the cotton inside the futon and the fabric of the surface cover. You can sleep in your favorite scent with a good sleep effect. Sleeping effect, insect repellent effect, etc. can be used by selecting the type of essential oil. When the scent decreases, it can be re-supplied and recreated by spraying a new microcapsule on the cover or inside fabric with a spray gun, or by applying it again. Most of the conventional scent sleep methods use small pieces of wood, mainly phyton chit and cypress thiol, and the scent lasts 6 to 12 months, but the scent could not be replenished.

(Utilization around toiletry: toilet seat, towel) Two types of microcapsules (perforated microcapsules and non-perforated microcapsules) are sprayed on a toilet seat or a towel with a spray gun. In the case of a toilet seat, the non-porous microcapsules are destroyed by the pressure during use, and the essential oil floats. After washing for a certain period of time, the binder flows out and the essential oil of the perforated capsule can be used. In the case of towels, physical contact by hand enables the use of non-porous microcapsules. If the fragrance or effect is insufficient due to the space volume, microcapsule spray can be added at any time with a spray gun. Until now, the deodorizing and sterilizing fragrance in sanitary has always been performed by releasing a fragrance into the room, but according to this use, the fragrance is emitted under specific conditions.

(Symptom relief of hay fever and rhinitis with mask etc.)
The above-mentioned liquid containing essential oil effective for rhinitis and hay fever is sprayed on gauze or the like in the mask. The movement of the mouth and the nose breaks the microcapsules inside the dough to generate essential oil and alleviate various symptoms by inhaling it through the nose. Until now, measures against hay fever and allergies have mainly used precision masks and spray guns in the nose to relieve symptoms. Some people have considerable resistance to using a spray gun to deliver symptomatic relief to the nose in front of a person, but for this application a microcapsule spray may be applied beforehand.

(Use for Marker) By applying microcapsules of an essential oil of about 1 micron to a variety of papers with a felt pen or the like, only the essential oil effect can be generated. Although the presence of the microcapsules is not apparent to the eye, the essential oil volatilizes as soon as the paper is moved, generating various effective scents. Because essential oils are highly volatile, they have low persistence and do not smell. Conventionally, artificial fragrances were sometimes applied to various types of paper together with colors, but when used by multiple people in one room, the scent of artificial fragrances may be muffled and multiple people may have discomfort, The goods failed. In this example, where the volatility of the essential oil is actively utilized, there is no problem.

(Use for maintaining driver's concentration, preventing drowsiness, etc.) By spraying a microcapsule spray having an aroma effect on the driving sheet, the microcapsules are destroyed by the movement of the driver's body. And volatilize essential oils. By temporarily wiping the face with a tissue containing essential oil that is effective for driving, it is also possible to temporarily obtain a strong concentration and awakening effect. Until now, the main purpose of car air fresheners was only to reduce or eliminate the smell inside the car, but the above usage can positively contribute to safe driving.

(Deodorization of body odor and the like due to sweat and secretions) By spraying the microcapsule spray on the underarm sweat pad or the like, the microcapsules are broken by the movement of the arm and deodorized by the deodorizing and sterilizing effect of the essential oil. be able to.

(Use as Hair Spray) Microcapsule spray can be used as a hair spray. The microcapsule spray does not emit fragrance in a static state, but if it is sprayed on the hair with a spray gun or the like, the microcapsules are broken by the natural movement of the hair, and the scent of essential oil drifts from that moment. However, because essential oils are highly volatile, the scent quickly disappears unless you move.

(Hair Spray) An unpleasant odor such as tobacco and grilled meat can be eliminated by applying an essential oil having a deodorizing effect such as a lavender to hair and using it. Unlike an ordinary hair spray, it is an essential oil, so it has high volatility and does not leave an odor. In this case, the slurry of the microcapsules: the binder: the solvent was 1: 0.1 to 0.5: 40 to 70 to reduce the amount of the binder.

[0022]

As described in detail above, the essential oil solution according to the present invention is obtained by adding a microcapsulated slurry of essential oil to an aqueous solution by adding an aqueous binder, dispersing the slurry into the human body, hair, fibers and the like. It is configured to be possible. Therefore, it can be easily used by timely spraying with a spray or the like. In addition to the non-porous microcapsules of ordinary essential oils, perforated microcapsules are also prepared and an aqueous binder and water are added, or pre-coated on fibers, etc.
Spraying with a spray gun or the like as needed has enabled a wide range of applications.
