Abstract

PURPOSE:To exhibit excellent sensitive deodorizing effect even with the amt. of use which does not exhibit the difference in individual taste related to smell to an org. acid-type odor which is a main component of the odor of sweat, the odor of body or the abnormal odor of socks by incorporating a plant essential oil into a deodorant for the org. acid-type odor as an essential ingredient. CONSTITUTION:A plant essential oil is incorporated into a deodorant for the org. acid-type odor as an essential ingredient. The plant essential oil is obtd. from at least one plant selected from among the Rutaceae family, the Zingiberaceae family, the Lauraceae family, the aciculate leaf family, the Myrtaceae the Gramineae family, the Oleaceae family, the rose family, the pine tree family, the Cupressaceae family and the Usneaceae family. Then, even when the amt. of use is in such a level that the difference in individual taste related to smell is not exhibited, strength of the odor is decreased to an org. acid-type odor by a sensitive neutralizing action wherein the smell of the plant essential oil and the org. Acid-type odor are mixed and canceled each other and the degree of unpleasant feeling is improved and the bad odor is deodorized and the odor after mixing is turned not to be unpleasant.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, among malodors and offensive odors, is particularly sensitive to organic acid-based odors such as isovaleric acid and normal butyric acid, which are the main components of sweat odor, body odor, or offensive odor of socks. The present invention relates to a deodorant capable of deodorizing by a neutralizing action.

[0002]

2. Description of the Related Art Generally, smoke and waste liquid from factories, cigarettes and raw sewage, kitchen garbage, and the like are sources of offensive odors and offensive odors, and there are various types thereof. In the home, odors from toilets, kitchens, pets, cigarettes, etc., sweat odors, body odors, and off-flavors of socks cause discomfort, irritation, headaches, and the like. In particular,
Since the air conditioner is often kept in a closed room at the time of operation, a countermeasure against these bad odors and offensive odors is a big problem.

Conventionally, the following methods (1) to (3) are roughly classified as methods for eliminating such an offensive odor or a strange odor. Sensory deodorization method: A method that masks offensive odors and offensive odors by the fragrance emitted by aromatic substances 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 deodorizing method: A method of deodorizing by chemically reacting (neutralizing, adding, condensing, oxidizing, etc.) with a malodorous or offensive odor component. 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.

[0005]

Among these, the above-mentioned sensory deodorizing method is a method mainly used in ordinary households. However, the conventional sensory deodorizing method uses a so-called masking effect to conceal the target odor against an offensive odor and a foul odor source, and
In this method, in most cases, the odor after mixing may be felt more strongly or may be more unpleasant than the odor and offensive odor before mixing. Furthermore, since the scent of the aroma substance itself is strong, the smell causes an unpleasant mood, or an atmospheric odor of a specific space such as a toilet, a living room, or a car.
Often they feel unpleasant. Furthermore, since it has a strong scent that can clearly recognize the odor,
The difference in individual preference is a problem. In this way, the current sensory deodorant method has many drawbacks and it is hard to say that it removes offensive odors and off-flavors [Technical Information Institute "Development and development of new deodorants and industrial deodorants. Approach to commercialization ”, supervised by Masaki Inari, 1989].

In view of such circumstances, the present invention provides an organic acid-based odor such as isovaleric acid and normal butyric acid, which are the main components of bad odors and offensive odors, such as sweat odor, body odor, and offensive odor of socks. On the other hand, even if the amount used is such that there is no difference in preference for individual scents, it is possible to exert an excellent sensory deodorizing effect and to eliminate the unpleasant odor after use. An object is to provide an odorant.

[0007]

In order to solve the above problems, the inventors have made various studies. As a result, if the plant essential oil is included as an essential component, the scent of the plant essential oil and the organic acid-based odor are mixed and offset each other, even if the amount used is such that there is no difference in preference regarding individual scent. By the sensory neutralizing action that is performed, the odor is deodorized,
The present invention has been completed by confirming by experiments that the odor after mixing is not unpleasant.

Therefore, the deodorant according to the present invention is
It is a deodorant for organic acid odors and is characterized by containing plant essential oil as an essential component. The plant essential oil used in the present invention is generally obtained from each organ such as plant flower, bud, leaf, petiole, fruit, stem, root, branch, stem, bark, mainly by steam distillation, squeezing and the like. It is volatile and emits a fragrance.

The type of plant for obtaining the plant essential oil is not particularly limited, but examples thereof include citrus family, ginger family, aeriaceae family, camphoraceae family, cinnamaceae family, peach family family, gramineae family, oleaceae family, rose family family, Pinaceae, cypress family,
Examples include plants of the family Sargassum. As the plant, only one kind may be used, or two or more kinds may be used in combination.

Specific examples of plant essential oils that can be used are not particularly limited as long as they are effective against organic acid odors. For example, cardamom oil, petiglen oil, cilantro oil, muss oil, rose brazilian. Oil, cassia oil, rosemary oil, cinnamon oil, ginger oil, clove oil, citronella oil, lemon oil, rose oil, lavender oil, orange oil, bergamot oil, caraway oil, bai oil, vetiver oil, neroli oil, cedar wood (Cedar) oil, jasmine oil, bamboo (bamboo) oil, pine oil, phenel sweet oil, thyme (red musk root) oil,
Examples include plum oil. 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 it is preferably an amount such that the odor intensity, which will be described later, of the deodorant used for a bad odor or an offensive odor will be 2 or less. . If the upper limit of this range is exceeded, the scent of the essential oil becomes too strong, so that the masking effect is expressed, or the strong scent gives an unpleasant feeling by staying in a specific space for a long time. This is because there may be a problem of difference.

The deodorant of the present invention may contain water, an organic solvent or the like as a diluent, and may contain a surfactant, if necessary. The organic solvent that can be used is not particularly limited, for example, methanol,
Alcohols such as ethanol, methyl ethyl ketone,
Examples thereof include hydrophilic organic solvents such as ketones such as acetone, and hydrophobic organic solvents such as petroleum ether, hexane, ethyl acetate and the like.

The surfactant that can be used is not particularly limited, and examples thereof include cationic surfactants, anionic surfactants, amphoteric surfactants and nonionic surfactants. The deodorant of the present invention is, if necessary, a component having a deodorizing effect by a chemical reaction, for example, a deodorant active component extracted from a plant, L-tartaric acid, maleic acid, succinic acid, malic acid. , One or more kinds of organic acids such as citric acid and lactic acid, and chemical substances such as glyoxal may be contained. In this case, the sensory deodorant effect and the chemical deodorant effect 2
It is a deodorant that has both deodorant effects. The above-mentioned deodorant active ingredient extracted from the plant is, for example,
Water, a hydrophilic organic solvent, or a mixed solvent thereof from each organ of the plant such as Oxalis, Dokudami, Tsuga, Ginkgo, Japanese black pine, Japanese larch, Japanese red pine, kiri, Holly butterflies, lilac, oyster butterbur, butterbur, forsythia, etc. It is a deodorant active ingredient extracted by using.

Regarding the method of using the deodorant of the present invention,
The method is not particularly limited, and examples thereof include a method in which a spray can is enclosed with a propellant and the like, and sprayed. Examples of the propellant include LPG (liquefied natural gas), DME (dimethyl ether), CFC gas, carbon dioxide gas, compressed air, and the like, but are not particularly limited.

[0015]

[Function] When the essential oil of plant is included as an essential component, the odor of plant essential oil and the odor of organic acid are compared with the odor of organic acid, even if the amount used is such that there is no difference in preference for individual scent. Due to the sensory neutralizing action in which and are mixed with each other to cancel each other, an excellent deodorizing effect is exhibited, and the odor after mixing is not unpleasant.
