Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a deodorant that eliminates bad odors and strange odors [Background Art] Generally, bad odors and strange odors are caused by factory smoke and liquid waste, cigarettes and frozen fields, and The source is kitchen waste, etc., and there are a wide variety of types of foul odors and strange odors. especially,
Since odor °ζ in the home is often kept in a closed room when air conditioning equipment is in operation, countermeasures against these foul odors have become a major problem.

There are four ways to eliminate these bad odors and strange odors:
There are two ways.

■ Sensory deodorization method: A method of masking bad odors and foreign odors using aromatic substances (fragrances).

■Physical deodorization method: A method that removes foreign odors through ventilation and diffusion, or uses activated carbon to absorb odors.

■ Chemical deodorization method: A method of chemically reacting (neutralization, addition, condensation, oxidation, etc.) with malodor and off-flavor components to make them odorless.

■ Biological deodorization method: A method that reduces and kills bacteria that cause spoilage, prevents spoilage, and prevents the occurrence of bad odors.

The sensory deodorizing method (2) is a method that is mainly practiced in households, and is a method that uses the fragrance of the deodorant itself to deodorize bad odors and foreign odors. However, with this method, it is difficult to balance the fragrance and odor, and people have different tastes in the scent of deodorants, which can sometimes make them feel disgusted. It's hard to say. Although the physical method (2) is widely used, there are problems in that it requires equipment, and activated carbon does not have a long-lasting adsorption effect on bad odors and off-flavor components. In addition, chemical deodorization method (1) is not common because it is extremely difficult to select a substance that reacts effectively with a wide variety of malodorous components, and care must be taken in handling the chemicals used. Furthermore, the biological deodorizing method described in (2) also requires equipment and has the disadvantage of slow onset of effects, and the current situation is that each deodorizing method has its own advantages and disadvantages.

[Purpose of the invention]

This invention was made in view of the above circumstances, and an object of the present invention is to provide a deodorizing agent which is itself odorless and has a high deodorizing effect on various malodorous components.

[Disclosure of the invention]

In order to achieve the above objective, the inventors conducted extensive research and found that by using a mixture of the compound represented by the general formula below and tannic acid as the active ingredient of a deodorant, the compound itself is odorless. It has been discovered that a deodorant can be obtained that can instantly respond to a wide range of odors.

This invention will be described in detail below.

The deodorant according to the present invention comprises a compound represented by the above general formula, that is, a phenolic compound represented by pyrogallol, pyrocatechol, gallicic acid, pyrotocatechuic acid, etc., and tannic acid having the above structure. In the mixture, two or more of the phenolic compounds may be used in combination.

The mixing ratio of the phenolic compound and tannic acid is phenol compound:tannic acid=1=0.1 to 10.
It is preferable to set it within the range of 0.

The above-mentioned deodorizing component may be one that has been purified by chemical synthesis, or one that has been extracted from a plant and separated and purified.

When the above compound is used as a deodorant, it may be used in either liquid or solid form. An embodiment in which the above compound is used in liquid form includes, for example, an embodiment in which the above compound is dissolved in water, and an embodiment in which it is used in solid form includes, for example, an embodiment in which the above compound is adsorbed onto a carrier. When used after being dissolved in water, it is preferable to set the concentration of the above compound in the range of 0.1 to 1.0 wt% from the viewpoint of effectiveness. In addition, when used by adsorbing it on a carrier,
The ratio of the above compound to the carrier is 10 to 0.0 on a weight basis.
It is preferable to set the ratio of 1:l in terms of effectiveness.There are various ways of using the above compound as a deodorant other than the above-mentioned ways. To make it last, glycerin,
It is effective to use additives such as propylene glycol in combination.

The deodorant produced in this way is odorless itself and can effectively and quickly contribute to the deodorization of a wide range of ammonia, amines, mercaptans, and the like.

The present invention will be explained below based on examples.

(Example 1.2.3) Fl
Example 2 (pyrogallol + tannic acid), Example 3
A deodorant of (Gallic acid + Tannic acid) was obtained.

In order to examine the deodorizing effects of these deodorants, the following tests were conducted. That is, target odors were ammonia, trimethylamine, and ethyl mercaptan, and a certain amount of the three types of deodorants mentioned above were added to these odors, and six panelists (three men, one woman, and three women) were given the results shown in Table 1 below. The odor was evaluated based on the six levels shown. The results are shown in Tables 2-4. The numerical values in Tables 2 to 4 are the differences in evaluation values before and after addition of the deodorant, and the larger the value, the greater the deodorizing effect.

Table 1 (Margin below) As shown in Tables 2 to 4, all mixed deodorants contain 31
It showed a high deodorizing effect on Li odor.

(Example 4) Protocatechuic acid and tannic acid were mixed in equal amounts and prepared into a 1% aqueous solution to obtain the deodorant of Example 4.

When I sprayed this deodorant on my stinky shoes, the smell completely disappeared.

(Example 5) Three components, pyrocatechol, gallic acid, and tannic acid, were mixed at i:t:2 to form a 10% aqueous solution. When absorbent cotton impregnated with this aqueous solution was placed in a refrigerator that smelled of meat and vegetables, and three days later the inside of the refrigerator smelled, the odor had completely disappeared.

〔Effect of the invention〕

As described above, in the deodorant of the present invention, a mixture of the phenolic compound represented by the above general formula and tannic acid is used as the deodorizing active ingredient, so the deodorant itself is odorless and is not harmful to humans. The result is a deodorant that is non-hazardous and can be used in any form. In other words, since this deodorant itself is odorless, it does not cause disgust in people due to its own odor, unlike conventional deodorants.
It does not require large-scale equipment and can deal with a wide range of odors such as ammonia, amines, and ethyl mercaptan, so it can effectively deal with everything from odors in factories to odors in the home and even odors in toilets.
