Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to deodorize a methyl mercaptan odor, which is a main component such as food odor, among odors and offensive odors by a sensory neutralizing action (smelling offset action). Deodorant that can be.

[0002]

2. Description of the Related Art Generally, smoke and waste liquor from factories, cigarettes and raw sewage, and kitchen garbage are sources of bad odors and offensive odors. In the home, odors from toilets, kitchens, kitchen garbage, pets, cigarettes, etc., sweat odors, body odors, and off-flavors of socks cause discomfort, irritation, headaches, and the like.
Especially in the summer, etc., it is often troubled, and when the air conditioner is operated, it is often kept in a closed room.
Countermeasures against these offensive odors and offensive odors have become 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 of masking 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 microorganisms that cause decay,
How to prevent spoilage and prevent the generation of foul odors.

[0005]

Among these, the above-mentioned sensory deodorizing method is a method mainly practiced in general households. However, the conventional sensory deodorizing method uses a so-called masking effect to conceal the target odor against an offensive odor and an offensive odor source by using an aromatic substance having an extremely strong intensity.
In this method, the odor after mixing can be felt more strongly (the odor intensity increases as described below) and the odor becomes more unpleasant (comfort or discomfort as described below) compared to the odor and unpleasant odor before mixing. In most cases). In addition, since the fragrance itself has a strong odor, the odor may cause an unpleasant sensation, or may cause an odor in a specific space such as a toilet, living room, or car. Often they feel unpleasant odor. Furthermore, since the scent has a strength that allows the odor to be clearly recognized, individual preference differences become a problem. In this way, the current sensory deodorant method has many drawbacks, and it is hard to say that it is capable of eliminating bad odors and offensive odors [Technical Information Institute "Development and development of new deodorants and industrial deodorants. "Approach to commercialization", supervised by Masaki Inari, 1989].

[0006] In view of such circumstances, the present invention uses the malodor and offensive odors to the extent that there is no difference in preference for individual scent, especially for methyl mercaptan odor which is a main component such as food waste odor. An object of the present invention is to provide a deodorant capable of exhibiting an excellent sensory deodorizing effect even in an amount, and capable of making the odor after use unpleasant.

[0007]

In order to solve the above problems, the inventors have made various studies. As a result, by including the plant essential oil as an essential component, even if the amount used is such that there is no preference difference regarding the scent of the individual, the scent of the plant essential oil and the methyl mercaptan odor are mixed and offset each other. It was confirmed by experiments that the odor intensity is lowered by the sensory neutralizing action, the pleasantness / discomfort is improved, the bad odor is eliminated, and the odor after mixing is not unpleasant. completed.

Therefore, the deodorant according to the present invention is
It is a deodorant for methyl mercaptan odor 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, etc., mainly by steam distillation, pressing and the like. It is volatile and gives off an aroma.

The type of plant for obtaining the plant essential oil is not particularly limited, but examples thereof include camphoraceae, sarcogaceae, umbelliferae, perillaceae, cinnamaceae, arachnidaceae, oleaceae, pinaceae, Examples include plants of the family Gramineae. The plant may use only one kind,
Alternatively, 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 methyl mercaptan odor, for example, cedar wood (cedar) oil, sage oil, clove oil, jasmine oil, pine oil, Fennell sweet oil, aspic oil, muss oil, citronella oil, caraway oil, bay oil, cilantro oil, cinnamon oil, bamboo oil,
Examples include plum oil and patcholly oil. 1 vegetable essential oil
Only one species may be used, or two or more species 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 in detail later, of the deodorant used for bad odors and off-flavors is 1 or less. .. If the upper limit of this range is exceeded, the scent of the essential oil becomes too strong, so that a masking effect is expressed, or a strong scent is left in a specific space for a long time to give an unpleasant feeling, and the individual's preference for the scent described above. This is because a difference problem may occur.

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 plants 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 butterbur, lilac, butterbur, butterbur, Tsuwabuki, or Forsythia 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. Further, a porous carrier such as zeolite, aluminum silicate, silica gel, polyester, calcium silicate may be impregnated with the deodorant of the present invention.

[0014]

[Effect] By including plant essential oil as an essential component, the fragrance of plant essential oil and the odor of methyl mercaptan are different from the odor of methyl mercaptan even if the amount used is such that there is no difference in preference regarding personal scent. Due to the sensory neutralizing action of mixing and canceling each other, the odor intensity is reduced, the pleasantness / discomfort is improved, the bad odor is eliminated, and the odor after mixing is not unpleasant.

[0015]

EXAMPLES Specific examples and comparative examples of the present invention will be shown below, but the present invention is not limited to the following examples. In addition, the odor intensity sensory test and the pleasantness / discomfort degree sensory test conducted in the following Examples and Comparative Examples were evaluated as follows with respect to the odor intensity and the pleasantness / discomfort degree.
