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.

In order to find a deodorizer that can be effectively used against a wide range of sources of malodors, it is important to have high safety as well as deodorizing effectiveness against malodorous substances.

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 tea confection extract is not sufficiently safe to the human body. However, there are problems with storage stability, and the deodorizing effect tends to decrease due to thermal deterioration and photodeterioration, so none of them are preferable as a deodorant that satisfies deodorizing effect, safety, and storage stability at the same time. There wasn't.

(Problems to be Solved by the Invention) In light of the above-mentioned conventional drawbacks, the present invention has sufficient safety for the human body, storage stability, in particular, no heat deterioration or photodeterioration, deodorizing effect, safety, The aim was to develop a deodorant that simultaneously satisfies storage stability.

cus Maxim, var, giganteus
It is a plant that has cultivated species such as L. l1ort, ).

Required parts of such starting materials may be used singly or in a mixture, and plants may be mixed together and left raw or dried.
It is extracted with a polar solvent, a non-polar solvent, or a mixed solvent thereof without being cut into small pieces, and if necessary, it is concentrated to remove the solvent, or it is 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.

The amount of the deodorizing active ingredient of this invention varies depending on the purpose, but is 0.001 to 50% (% by weight 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 mouth rinses, mouthwashes, mouthwashes, chewing gum, candy, etc., for removing bad breath such as garlic odor, etc. In addition to being used as a deodorizer, it can also be used as a deodorizer for food waste, refrigerators, indoors, cars, and toilets by supporting it on a carrier and using its vapor pressure, or by preparing it in a liquid form that can be sprayed directly with a propellant. 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.
