Description

Description: TECHNICAL FIELD The present invention relates to a deodorant for purifying air, deodorizing air, and the like.

[Conventional technology]

In general, as foul odors and odors, smoke and waste liquid from factories, cigarettes and human waste, kitchen garbage, and the like are sources, and the types of odors and odors are various. At home, odors from toilets, kitchens, pets, cigarettes and the like cause discomfort, irritation, headaches and the like. In particular, since the air conditioner is often kept in a closed room when the air conditioner is operated, countermeasures against these bad smells and odors have become a serious problem.

There are roughly the following four methods for eliminating such bad smells and off-flavors.

Sensory deodorization method: A method of masking offensive odors and off-flavors with aromatic substances (such as essential oils)

Physical deodorization method: A method of diluting and removing malodors by ventilation and diffusion, adsorbing odors using silica gel or activated carbon, or including odorous substances by inclusion compounds such as cyclodextrin.

Chemical deodorization method: A method of chemically reacting (neutralizing, adding, condensing, oxidizing, etc.) with malodorous or off-flavor components to deodorize. For example, an open flame combustion method or an oxidation method using an oxidizing agent such as ozone or potassium permanganate.

Biological deodorization method ... kills microorganisms that cause decay,
A method of preventing rot and preventing the generation of odors.

In addition, there is a method of deodorizing using wood vinegar obtained by carbonizing wood.

The sensory deodorizing method is a method which is mainly used in ordinary households, and makes it less likely to sense offensive odors and off-flavors due to the odor of the deodorant itself. However, aromatic substances have a limited ability to remove odorous substances, it is difficult to balance odors and odors, and the odors possessed by deodorants have a taste of human beings and sometimes disgust. It is hard to say that it is a general deodorization method. Physical methods have been widely used since ancient times, but in addition to problems such as the need for equipment and the fluctuating room temperature, the adsorption effect of offensive odors and off-flavor components is not sustainable,
If it becomes saturated, there is a problem that odor components are released. Further, in the chemical deodorizing method, it is extremely difficult to select a substance that effectively reacts to various kinds of malodorous components. In addition, it is not general, because care must be taken in handling the used chemicals and the chemicals may deteriorate in the air.
Biological deodorization methods are also not suitable for use in removing odors in the atmosphere, require the use of equipment, and have the drawback that their effects are slow to develop. At present, each has its strengths and weaknesses. [Refer to the Industrial Research Committee, “New Deodorizing Technology,” Susumu Kokubu (1981)].

Therefore, an attempt was made to use an extracted component from a plant as a deodorant, and some of the inventors first developed a deodorant containing a deodorant active ingredient obtained from a plant as a main component and applied for a patent. An application has been filed (see Japanese Patent Application Laid-Open No. 1-218456).

The deodorant active ingredient obtained from plants is odorless and safe by itself, and in addition, has the advantage that it does not require large-scale equipment as a deodorant device. .

[Problems to be solved by the invention]

The above-mentioned deodorant, which some of the inventors have developed as a main component, a deodorant active ingredient obtained from a plant earlier, is useful for all kinds of odors in daily life, for example, amines such as trimethylamine which is a rotten smell of fish and meat. Odors, such as hydrogen sulfide, the rotting odor of eggs and milk, mercaptans such as methyl mercaptan, which are rotting odors of vegetables and garbage; High deodorant effect on the whole. However, because the volatility of the deodorant itself is small, if not operated so as to act directly on the odor source, the immediate effect is reduced, the deodorant effect is slightly reduced, and the odor itself does not smell However, the odor after the reaction sometimes became an unpleasant odor.

Therefore, an object of the present invention is to provide a deodorant which always has an immediate effect on the above-mentioned odors in general, and has a high deodorizing effect, and the odor after the reaction is not unpleasant and unpleasant. I do.

[Means for solving the problem]

In order to solve the above-mentioned problems, a deodorant according to the present invention is a deodorant containing, as a main component, a deodorant active ingredient obtained from a plant, menthol, cineol, geraniol, vetiverol, vetiven, vetiben, l-menthol. , Citronellal, l-linalool, linaliyl acetate, α-terpineol, and dipentene are added.

The type of plant for obtaining the deodorant active ingredient containing the deodorant of the present invention as a main component is not particularly limited, but, for example, oxalis, dokudami, tsuga, ginkgo, black pine, larch, red pine, drill, holly Preference is given to using mokusei, lilac, primrose, butterbur, camellia and forsythia. However, the present invention is not limited to these, and other than the above-mentioned Lentaceae plants and Pinaceae plants can also be widely used.

The deodorant active ingredient extracted from each of the organs such as leaves, petiole, nuts, stems, roots and bark of these plants is used as a main component of the deodorant according to the present invention. The method is not particularly limited. For example, water, or a hydrophilic organic solvent such as alcohols such as ethanol and methanol, and ketones such as methyl ethyl ketone and acetone is added to the raw material plant, and a deodorizing active ingredient is added using a Soxhlet extractor or the like. A method of performing heat extraction is employed. This extraction operation may be performed using a mixed solvent of these hydrophilic organic solvents and water. The extract thus obtained is used, for example, as it is, or after being diluted with a suitable solvent, concentrated, or concentrated to dryness. The deodorant active ingredient and the extract may be used alone or in a combination of two or more. In addition, extraction is not a one-stage extraction like this,
If necessary, the odor component (or odor component) of the raw material plant may be eluted and removed in advance using a hydrophobic organic solvent such as hexane or petroleum ether. Further, a steam distillation method may be used. Deodorant active ingredients obtained from plants generally have non-volatile properties.

Glyoxal is added to the thus obtained deodorant active ingredient (which may be in the form of an extract dissolved in an appropriate solvent) if necessary, and further, if necessary, such as an organic acid and a surfactant. At least one is added.

When the deodorant contains glyoxal, the deodorizing effect of the deodorant active ingredient becomes more excellent.

Examples of the organic acid include at least one organic acid selected from the group consisting of L-tartaric acid, maleic acid, succinic acid, malic acid, citric acid, and lactic acid. The surfactant may be, for example, any of a cationic surfactant, a hidden ionic surfactant, an amphoteric ionic surfactant, and a nonionic surfactant, and the type thereof is not particularly limited.

The amount of glyoxal added is not particularly specified,
For 1 part by weight of the deodorant active ingredient (or extract),
It is preferably 0.1 to 500 parts by weight. The amount of the organic acid to be added is not particularly limited, but the total amount of the organic acid is 0.1 to 2 parts by weight based on 1 part by weight of the deodorant active ingredient (or extract).
Preferably it is 50 parts by weight. The amount of the surfactant to be added is not particularly limited either, but it is 0.1 to 10 parts by weight based on 1 part by weight of the deodorant active ingredient (or extract), and benzalkonium chloride, cetylpyridinium chloride or the like is used. Preferably.

In addition, the deodorant of the present invention, depending on the intended use,
Ethanol may be added as necessary. When ethanol is added, the amount of addition is, for example, 99 parts by volume or less of ethanol relative to 1 part by volume of the deodorant before adding ethanol.

The present invention is characterized in that the following compounds are added in addition to the above essential components and optional components. That is, compounds derived from plant essential oils, for example, menthone,
Cineole, geraniol, beniverol, vetiven,
Betiben, l-menthol, citronellal, l-linalool, linaliyl acetate, α-terpineol,
And any one compound selected from the group consisting of dipentene or a combination of two or more compounds. The method for producing these compounds is not particularly limited. By mixing these compounds with odor (odor),
Offensive odors are intuitively offset. Also, these compounds
Compared with vegetable essential oils and the like, similar effects can be achieved with a smaller amount, and coloring and the like can be reduced.

The amount (total amount) of the compound is not particularly limited, but is preferably contained in the deodorant at 0.00001 to 0.1% by volume. When the amount exceeds the upper limit of this range, the fragrance of the compound becomes too strong, so that a masking effect may be exerted. When the amount is less than the lower limit, the effect of canceling the odor may not be exhibited.

It is preferable that the pH of the deodorant prepared in this manner is adjusted to a predetermined range in order to further enhance the deodorizing effect. For example, adding an alkaline solution such as sodium hydroxide or a solution having a buffering action
It is recommended to adjust the pH from weakly acidic to weakly basic (eg, pH 3-9).

No particular limitation is imposed on the mode of use of the deodorant. For example, a solvent, a spray type, a mousse form, or a carrier impregnation, a powder, a tablet, a granule, etc.
A wide variety can be selected depending on the application.
