Description

TECHNICAL FIELD The present invention relates to a deodorant and a deodorant spray used for air purification, deodorization and the like.

[Conventional technology]

Generally, foul odors and offensive odors are generated from smoke and waste liquor from factories, cigarettes and raw sewage, and kitchen garbage, and there are various types of offensive odors and offensive odors. At home, odors from toilets, kitchens, pets, cigarettes, etc. cause discomfort, frustration, and headaches. In particular, since the air conditioner is often kept in a closed room during operation, countermeasures against these offensive odors have become a big problem.

Methods for eliminating such offensive odors and offensive odors are roughly classified into the following 4
There are two ways.

Sensory deodorizing method: A method to mask offensive odors and offensive odors with aromatic substances (fragrant essential oils, etc.).

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: Chemical reaction (neutralization, with offensive or offensive odor components)
Deodorization by adding, condensing, oxidizing, etc.). For example, a direct-burning method or an oxidizing method using an oxidizing agent such as ozone or potassium permanganate.

Biological deodorant method: A method of destroying the microorganisms that cause spoilage to prevent spoilage and prevent the generation of foul odors.

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

The sensory deodorant method is a method mainly used in ordinary households, and it removes offensive odors and offensive odors by the odor of the deodorant itself. However, aromatic substances have a limited ability to remove odorous substances, and it is difficult to balance odor and odor. Moreover, the fragrance of deodorants has a human preference and sometimes dislikes. It is difficult to call it a general deodorant method. The physical deodorizing method has been widely used for a long time, but in addition to problems such as the need for equipment and room temperature fluctuations, the adsorption effect of malodorous and offensive odors is not sustainable or saturated. There is a problem that odorous components are released when the state is reached. Further, in the chemical deodorization method, it is extremely difficult to select a substance that effectively reacts with a wide variety of chemical components.
Further, it is not common because the medicine used must be handled with care and the medicine may deteriorate in the air. The biological deodorizing method is also not suitable for the purpose of removing odors in the atmosphere, requires a device, and has a drawback that the effect is delayed. As described above, each deodorizing method has advantages and disadvantages at present.

Under such circumstances, the inventors have already decided to use an extract obtained from a plant as an active ingredient of a deodorant, and as a result of repeated studies, as a result, the deodorant of nitrogen-based and sulfur-based odors was previously found. , A deodorant containing an extract obtained from these plants as an active ingredient was developed and a patent application has been filed (Japanese Patent Laid-Open No. 61-94659 and Japanese Patent Laid-Open No. Sho 61-94659). 6
1-94660, JP-A-61-119268, etc.).

The active ingredient in the plant itself is odorless and safe, and in addition, it has the advantage of not requiring large-scale equipment as a deodorizing device, and therefore, it is expected to continue in the future.

[Problems to be Solved by the Invention]

However, the deodorant component extracted from natural plants has a limited deodorant ability as it is. Also, if left for a long time, the hue may change, a precipitate may form, etc.
There are problems such as poor stability over time.

In view of the above circumstances, the present invention provides all kinds of odors in daily life, for example, amines such as trimethylamine which is a rotting smell of fish and meat, hydrogen sulfide which is a rotting smell of eggs and milk,
Mercaptans such as methyl mercaptan which is a rotten odor of vegetables and garbage, ammonia in toilet odors, tobacco odors, organic acids such as butyric acid which is a odor of sweat and body odor, etc. have a high deodorizing effect on all odors, and When it is made liquid, even if it is left for a long time, the deodorant has stability over time without change in hue, formation of precipitate, deterioration of deodorant power, etc., and the deodorant is used as a deodorant base. It is an object to provide a deodorant spray that does.

[Means for Solving the Problems]

In order to solve the above problems, the present invention is a deodorant containing an extract obtained from a plant as an active ingredient, which is a group consisting of L-tartaric acid, maleic acid, succinic acid, malic acid, citric acid and lactic acid. At least one organic acid selected from among these, glyoxal, and a surfactant are added.

Further, the present invention is a deodorant spray obtained from a plant and containing an extract as an active ingredient, characterized by using the above deodorant as a base.

The raw material plant of the deodorant according to the present invention is not particularly limited, but examples thereof include oxalis, hemlock, hemlock, ginkgo, black pine, larch, red pine, kiri, holly sol, lilac, pearl oyster, butterbur, camellia and forsythia. It is preferable to use. However, the present invention is not limited to these, and other Astragalus plants, Pinaceae plants and the like other than the above can be widely used.

The deodorant according to the present invention includes leaves of these plants, petioles,
Substances extracted from various organs such as fruits, stems, roots, and bark are used as deodorant active ingredients, but the extraction method is not particularly limited. For example, one or more kinds of the above-mentioned raw material plants are added with one or more kinds of hydrophilic organic solvents such as water or alcohols such as ethanol and methanol and ketones such as methyl ethyl ketone and acetone. , A Soxhlet extractor or the like is used to thermally extract the deodorant components. Further, this extraction operation may be performed using a mixed solvent of these hydrophilic organic solvent and water. Incidentally, the extraction is not such a single-stage extraction, and if necessary, a hydrophobic organic solvent, for example, hexane, petroleum ether or the like may be used to elute and remove the odorous components of the raw material plant in advance. . In addition, the steam distillation method may be used to simultaneously remove the odorous components of the raw material plant and extract the deodorant components.

A deodorant is obtained by adding the above-mentioned additive to the thus obtained extract. Alternatively, if necessary, after distilling or concentrating the solvent from the extract to obtain the extract as a liquid or solid, dilute or dissolve the extract with an appropriate solvent, and add the above-mentioned additive. You may

As described above, the deodorant according to the present invention includes 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, glyoxal and A surfactant has been added.

The addition of the organic acid enhances the deodorizing power for nitrogenous odor. The amount of the organic acid added is not particularly limited, but it is a deodorant active ingredient. It is preferably 0.1 to 250 parts by weight (or the sum of those when a plurality of kinds of organic acids are used) per 1 part by weight of the extract obtained from the plant.

The addition of glyoxal enhances the deodorizing power against sulfur odors. Moreover, changes in hue, formation of precipitates, deterioration of deodorizing power, etc. are suppressed, and the deodorant is provided with stability over time. The addition amount of glyoxal is not particularly limited, but is 0.1 to 500 with respect to 1 part by weight of the extract.
It is preferably part by weight.

By adding the surfactant, the uniformity of the deodorant can be maintained and the antiseptic effect can be obtained. The surfactant may be any of a cationic surfactant, an anionic surfactant, a zwitterionic surfactant and a nonionic surfactant, and the type thereof is not particularly limited. Also,
The amount added is not particularly limited, but is preferably 0.1 to 10 parts by weight with respect to 1 part by weight of the extract.

In order to further enhance the deodorizing effect of the deodorant prepared in this manner, an alkaline solution such as sodium hydroxide or a liquid having a buffering effect may be added to remove the deodorant.
It is recommended to adjust the pH to 3-5.

The mode of use of the deodorant according to the present invention is not particularly limited, and it can be selected from a wide variety according to the application, such as liquid formulation, spray type, or impregnation into carrier, powder, tablet, and granule formulation. Can be done.

In particular, when using the deodorant as a spray type, depending on the mode of the deodorant spray, the purpose of use, with respect to the total weight of the components other than ethanol constituting the deodorant, 0.1 ~ 9
It is desirable to use a deodorant prepared to contain 9 times the weight of ethanol as the base of the deodorant spray. Further, examples of the deodorant spray include, but are not particularly limited to, a gas spray type spray with a spray gas and a hand-pressing pressure spray without a spray gas. In the case of the gas injection type spray, the injection gas is not particularly limited, but LPG, LPG / DME
A mixed gas can be exemplified.

In addition, it has a high deodorizing effect on all odors, and has stability over time without change in hue, formation of precipitates, deterioration of deodorizing power, etc. even when left for a long time.

〔Example〕

Specific examples and comparative examples of the present invention will be shown below, but the present invention is not limited to these examples.

-Examples 1 to 13-A plant is selected from the group consisting of Dokudami, Tsuga, Kiri, Japanese black pine, pearl oyster, Tsuwabuki, Forsythia, Larch, Oxalis, Ginkgo and Lilac according to Table 1 below, and selected as one plant. In contrast, with water at 50 ° C for 4 hours,
Alternatively, a solid extract was obtained by concentrating and drying the extract obtained by performing extraction with water at 60 ° C. for 3 hours using a rotary evaporator or a freeze dryer. The obtained extract was mixed with water, organic acid, and water so as to have the composition shown in Table 1 below.
Glyoxal and a surfactant (cetylpyridinium chloride) were added and mixed, and sodium hydroxide was added to the obtained aqueous solution to adjust the pH of the aqueous solution to a predetermined value shown in Table 1 below. In addition to the pH adjusted aqueous solution,
The deodorants of Examples 1 to 13 were obtained by adding the amount of ethanol shown in Table 1 below.

Next, each of the deodorants of Examples 1 to 13 obtained as described above is pushed by hand in a pressure spray can, or by enclosing it in a gas injection spray can together with a propellant gas,
The deodorant sprays of Examples 1 to 13 were obtained.

-Comparative Example 1-A deodorant and deodorant spray were obtained in the same manner as in Example 5, except that lactic acid was not added.

-Comparative Example 2-A deodorant and a deodorant spray were obtained in the same manner as in Example 5, except that glyoxal was not added.

-Comparative Example 3-A deodorant and a deodorant spray were obtained in the same manner as in Example 5, except that cetylpyridinium chloride was not added.

-Comparative Example 4-A deodorant and deodorant spray were obtained in the same manner as in Example 5, except that neither lactic acid, glyoxal, nor cetylpyridinium chloride was added.

After leaving the deodorant sprays (deodorants) obtained in Examples 1 to 13 and Comparative Examples 1 to 24 for 24 hours, their deodorizing ability tests were conducted as follows.

Each of the deodorant sprays obtained in Examples 1 to 13 and Comparative Examples 1 to 4 was placed in a container capable of being hermetically sealed, and further ammonia gas, hydrogen sulfide gas or methyl mercaptan gas was added to those containers as shown in Table 2 below. An amount corresponding to the indicated odor intensity of 5 was added and the container was sealed. Next, after spraying each deodorant spray in those containers and leaving it for a certain period of time, five panelists with similar olfactory scents smelled and evaluated according to Table 2 below. It was

The results are shown in Table 3.

As shown in Table 3, the deodorant spray according to the embodiment is
The nitrogen-based and sulfur-based malodors having an odor intensity of 5 shown in Table 2 above are deodorized from odorless to very faint. On the other hand, the deodorant spray according to the comparative example is inferior in deodorant power to the deodorant spray according to the example. That is, the deodorizing spray according to Comparative Example 1 to which the organic acid was not added had a reduced deodorizing power with respect to the nitrogen-based odor. Comparative Example 2 in which no glyoxal was added
The deodorant spray according to claim 1 has a reduced deodorizing power against sulfur odors. Comparative Example 3 in which no surfactant is added
The deodorizing spray according to No. 2 has a slightly reduced deodorizing power against nitrogen-based and sulfur-based odors. The deodorant spray according to Comparative Example 4, in which neither organic acid, glyoxal, nor surfactant was added, had a considerably reduced deodorizing power for nitrogen-based and sulfur-based odors.

Further, as a result of performing the same deodorizing ability test as above with respect to other odors (trimethylamine, nicotine, butyric acid), good results were obtained with any of the deodorant sprays according to the examples.

Furthermore, when the state of the deodorant liquid of the deodorant spray according to the Examples and Comparative Examples was observed, no change in the hue of the deodorant liquid or the formation of a precipitate was observed for any of the deodorant sprays according to the Examples, It had stability over time. In contrast,
With respect to the deodorant spray according to the comparative example, changes in the hue and the like of the deodorant liquid were observed.

As described above, in the deodorant and the deodorant spray according to the present invention, it is understood that if any one of the three types of additives is lacking, the deodorant power and the stability over time are deteriorated.

〔The invention's effect〕

Since the deodorant and the deodorant spray according to the present invention are configured as described above, they can overcome the above-mentioned conventional problems and exhibit a high deodorizing power for all odors. Furthermore, it has stability over time even if it is left for a long time without causing a change in hue, formation of a precipitate, deterioration of deodorizing power, and the like.
