Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a deodorizer, and its purpose is to have a good deodorizing effect on malodorous substances, and to use raw materials collected from ordinary edible plants. To provide a deodorant that is extremely safe and can be used as a deodorant in a wide range of fields such as oral, household, and even industrial use. be.

(Prior Art and Its Disadvantages) Conventionally, there are many deodorants for deodorizing malodorous substances.

Malodorous substances are substances that have an odor that makes humans uncomfortable, and include sulfur-based substances such as methyl mercaptan and diallyl disulfide, nitrogen-based substances such as trimethylamine,
There are other substances, usually harmful substances as well.

These malodorous substances are mainly generated in industrial waste, wastewater, and during industrial production processes, but they can also be generated in putrid foods and human bodies.

Bad breath from the human body, such as the odor of decomposed garlic after eating garlic, is a particular problem in interpersonal relationships, and there are various ways to eliminate it, such as chewing gum and brushing your teeth, but none of them are perfect.

In general, bad breath is caused by food particles, bacterial decomposition odor, decomposition gas, or pathological (periodontitis), etc. The odor is mainly caused by methyl mercaptan and diallyl dihydrogen, which is generated secondary to eating foods such as garlic. It is thought to be sulfide.

A major issue for eel deodorants that can be effectively used against these wide range of sources of malodors is that they must not only be effective in deodorizing the malodorous substances, but also be highly safe.

As deodorizing substances from this point of view, copper chlorophyllin sodium, tea (Thea 5inensis L.
.

) leaf extract is known.

However, sodium copper chlorophyllin usually only becomes effective when used in large amounts, so it cannot be said that the safety to the human body when used in large amounts is sufficient, whereas the safety of tea leaf extract to the human body is not sufficient. However, there are problems with the deodorizing effect, and none of them are preferable as a deodorant that satisfies both the deodorizing effect and safety.

(Problem to be solved by the invention) In light of the above-mentioned conventional drawbacks, the present invention aims to develop a deodorant that is sufficiently safe for the human body and satisfies deodorizing effect and safety at the same time. .

(Solution Means of the Invention) That is, the present invention solves the problem of Plantago maj
or L, var, asiatica) or its related plants, or an extract of at least one of the above-ground parts, underground parts, or seeds of at least one plant selected from plants related thereto. By providing a deodorant that is sufficiently safe for the human body, we have succeeded in creating a deodorant that satisfies both deodorizing effect and safety, and have arrived at this invention.

(Structure of the Invention) The starting material used in this invention is Plantago major L, var, a
siatica) or its related plants,
At least one of the underground part and the seeds can be effectively used.

Plantain, which is the starting material of this invention, refers to the family Plantainaceae (
Plantago) is a perennial plant that commonly grows on roadsides throughout Japan.The seeds are used as an anti-inflammatory, diuretic, and antitussive agent, and the whole plant is used medicinally as a diuretic, antitussive, and gastrointestinal medicine. .

A close relative of this plant is Plantain
tago depressa will > , Plantago depressa (Plantago depressa will)
1nn), etc.

Required parts of these starting materials can be extracted singly or in a mixture, or in combination with plants, raw or dried, cut into small pieces, or without being cut into pieces, with a polar solvent, a non-polar solvent, or a mixed solvent thereof. If necessary, it can be concentrated to remove the solvent, or it can be used as an essential component of a deodorant without being concentrated.

Extraction solvents used in this extraction include water, alcohols such as methanol and ethanol, and polar solvents such as ketones, esters, and ethers that have a relatively small molecular weight, that is, have a small number of carbon atoms, such as acetone, ethyl acetate, and diethyl ether. or one or more non-polar solvents such as n-hexane, petroleum ether, ligroin, cyclohexane, carbon tetrachloride, chloroform, dichloromethane, toluene, benzene, etc., or polar and non-polar solvents thereof. Extraction is performed using a mixed solvent.

This extract has an excellent deodorizing effect on malodorous substances, as shown in Examples and Test Examples below.

The extract obtained in the above-mentioned extraction operation is blended after removing the solvent, but in the case of only water or ethanol, it can also be blended into the deodorant as it is without removing the solvent.

Plantain used in this invention
jorL, var, asiatica) are blended into the deodorant according to the present invention as the above-mentioned extracts, but the required parts may be blended alone or in a mixture, and further, plants may be mixed and blended raw or dried. You can.

The amount of the deodorizing active ingredient of this invention varies depending on the purpose, but is o, ooi ~ 50% (wt% based on the entire deodorant)
, particularly preferably from 0.001 to 10%.

The deodorizing active ingredients of this invention may be used alone or in combination with other deodorizing active ingredients.

The deodorant according to the present invention can be prepared in various dosage forms.

For example, it can be prepared in the form of a solution (water, organic solvent, etc.), paste, powder, block, or the like.

The deodorizing active ingredient of the present invention stably exhibits a deodorizing effect even in the state of an aqueous solution or dissolved in an organic solvent.

For this reason, there are no restrictions on the selection of dosage forms, but specific examples include toothpaste, mouthwash, mouthwash, chewing gum, candy, etc. for oral use to remove bad breath such as garlic odor. In addition to being used as a deodorizing agent, it can also be applied to food waste, refrigerators, indoors, cars, and toilets by supporting it on a carrier and using its vapor pressure, or by spraying directly with a propellant in liquid form. It can be used as a household deodorant such as sewage treatment plants, fish processing plants, fishmeal manufacturing plants, livestock manure, poultry manure drying plants, industrial deodorizers that remove bad odors emitted from pulp factories, etc.

Next, specific formulation examples will be described, but the deodorant according to the present invention is not limited to these formulation examples.
