Description

The present invention relates to a deodorizing technique.

A number of deodorants have been proposed. Many body odor deodorants are commercially available.

By the way, the deodorant for eliminating the odor attached to the textile product (for example, clothing) targeted by the present invention has a requirement not required for the body odor deodorant.

That is, when the deodorant is sprayed on the clothes, the deodorant should not cause coloring or stains. If the clothes are colored or stained by the sprayed deodorant, you will not be able to wear the clothes. I have no choice but to clean it. Therefore, it is an absolutely essential requirement for a deodorant to eliminate the odor attached to textile products (for example, clothing) that the deodorant does not cause coloring or stains. In other words, it does not mean that it should have a deodorant effect. In this respect, stricter requirements than those required for body odor deodorants are fulfilled.

As a deodorant for eliminating the odor of textile products (for example, clothing), for example, Febreze (trade name: manufactured by P & G) using a deodorant component derived from corn, and Resesh using a deodorant component extracted from tea leaves. (Product name: made by Kao) etc. are commercially available.

In addition, a deodorant using a synthetic compound deodorant component instead of the deodorant agent using the deodorant component derived from the natural product has also been proposed (Japanese Unexamined Patent Publication No. 2007-282798). However, in recent years, as can be seen from the above-mentioned commercial products, attention has been focused on deodorants using deodorant components derived from natural products.

Japanese Unexamined Patent Publication No. 2007-282798

The problem to be solved by the present invention is a technique for easily and easily removing an odor attached to a textile product (for example, clothing) and not causing noticeable coloring or stains on the textile product (for example, clothing) at that time. Is to provide.

The odor of textile products (for example, clothing) can be easily and easily deodorized.

Does not cause noticeable coloring or stains on textile products (for example, clothing).

Hereinafter, embodiments of the present invention will be described.

The first invention is an agent (deodorant). The agent is, in particular, an agent that deodorizes the odor attached to textile products (for example, clothing). In particular, it is an agent for deodorizing odors derived from one or more kinds of components selected from the group of lipids and proteins attached to textile products (for example, clothing). It is an agent for deodorizing odors derived from one or more kinds of components selected from the group of lipid oxides and protein oxides attached to textile products (for example, clothing). The reason was that the deodorizing effect on the above-mentioned odor was remarkably excellent.

The agent contains tannins. The tannins are, in particular, condensed tannins. The tannin was preferably a tannin derived from a natural product. The tannin was particularly preferably persimmon tannin. The tannins are obtained, for example, by squeezing persimmons. Commercially available products (for example, manufactured by Tomiyama Co., Ltd. and Fuji Chemical Industries, Ltd.) may be used. When the above-mentioned tannins were used, the deodorizing effect on the above-mentioned odorous components was remarkably excellent. That is, the object of the present invention was effectively achieved.

Tannins are also contained, for example, in tea leaves. As tannins contained in tea leaves, catechins such as epicatechin and epigallocatechin are known. These are compounds generally represented by the following structural formulas.

On the other hand, persimmon tannin (condensation type persimmon tannin) is generally a compound represented by the following structural formula. The structure of the persimmon tannin is completely different from the structure of the tannin contained in the tea leaves. The present invention uses condensed tannins instead of the tannins contained in the tea leaves because it has a high effect of removing odors attached to clothes during meals such as in a yakiniku restaurant. That is, the tannin contained in the tea leaves could not exhibit the features of the present invention.

Condensed tannin has been proposed to have the effect of decomposing unsaturated aldehydes such as nonaner, which is a causative substance of body odor (aging odor), and improving body odor (aging odor) (Patent No. 421220). .. However, it has not been known that condensed tannin decomposes and deodorizes odorous substances derived from lipids and proteins. From this point, we are convinced that the present invention is novel and has an inventive step.

It is well known that condensed tannins are light brown to reddish brown. It is also well known that persimmon tannin (persimmon astringent) is used, for example, for cloth dyeing. In particular, it is widely known that persimmon tannin (persimmon astringent) easily penetrates into textile products. Dyeing using persimmon tannin (persimmon astringent) is called persimmon clothing and is also called traditional craft dyeing centered on Jeju Island (Japanese Patent Laid-Open No. 2011-12379). It is also well known that persimmon tannin (persimmon astringent) is used in tea-based paints. Japanese Unexamined Patent Publication No. 2008-163281 discloses that persimmon tannin is used as a reddish brown to brownish brown coloring agent for wood, cotton, paper and the like. Kakishibu paint is widely available on the market. If you spray your clothes with persimmon tannin, which is such a coloring substance, it is normal to think that it will penetrate the clothes and cause stains and stains. Therefore, even if it is found that persimmon tannin (persimmon astringent) decomposes odorous substances derived from lipids and proteins, the purpose is to deodorize (remove) the odor attached to textile products (for example, clothing). However, I am convinced that the idea of spraying persimmon tannin (persimmon astringent) on textile products (for example, clothing) was not born. From this point as well, we are convinced that the present invention is novel and has an inventive step.

The agent contains water. The tannin was 0.001 to 0.5 parts by mass with respect to 100 parts by mass of the water. It was preferably 0.005 part by mass or more. More preferably, it was 0.01 parts by mass or more. It was preferably 0.3 parts by mass or less. More preferably, it was 0.1 part by mass or less. That is, by setting the blending ratio as described above, when the agent was sprayed on the textile product, it exerted a deodorizing effect but did not cause stains or stains on the textile product. For example, if the amount of the tannin exceeds 0.5 parts by mass with respect to 100 parts by mass of water, stains and stains due to the tannin sprayed on the clothes become conspicuous, and the deodorizing effect is dramatic. It was not an improvement. On the contrary, when the amount of the tannin was less than 0.001 part by mass with respect to 100 parts by mass of water, the deodorizing effect of the tannin sprayed on the clothes was small. That is, the object of the present invention was not achieved when the compounding ratio was deviated from the above.

Persimmon tannin (persimmon astringent) has an antiseptic effect. Therefore, even if the agent of the present invention does not contain a preservative, the agent of the present invention has excellent storage stability. However, preferably, a preservative may be added from the viewpoint of further storage stability. However, it is necessary not to denature persimmon tannin (persimmon astringent). From this point of view, the preservative was preferably one or more selected from the group of preservatives derived from natural products. For example, corn-derived pentylene glycol (1,2-pentanediol and white yanagi bark extract can be mentioned. The preservative is preferably 0.01 to 0.5 parts by mass with respect to 100 parts by mass of the water. It was more preferably 0.05 parts by mass or more, and more preferably 0.3 parts by mass or less.

The second invention is a deodorizing method. The method is a method of applying the agent to a textile product after it has an odor. The agent may be attached to clothing in advance. That is, the odor can be decomposed and the generation of the odor can be suppressed. The method is a method of spraying the agent onto odorous clothing. The method is a method of spraying the agent after a meal toward clothing that has an odor in the meal.

The agent of the present invention is also excellent in safety to the human body. The agent of the present invention is basically sprayed on clothing or the like. When the agent of the present invention is sprayed on the clothes worn, it is expected that it will adhere to the skin such as the face and hands, and the hair. From this point of view, it is also an important requirement that the deodorant is highly biosafe. Tannin has been used since ancient times as a raw material for tooth black. In some cases, the persimmons are eaten without the astringency. It has also been used as a folk medicine for burns, frost burning, lowering blood pressure and detoxification. In addition, it is said to have astringent action, blood circulation promoting action, anti-inflammatory action and the like. Therefore, even if the contained tannin adheres to the skin or the like when the agent of the present invention is sprayed on clothing, not only the biosafety is excellent, but also a cosmetic effect can be expected.

Hereinafter, a more specific explanation will be given. However, the present invention is not limited to the following specific examples. Various modifications and applications are also included as long as the features of the present invention are not significantly impaired.
