Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to crushed leaves and fruits of Cupressaceae plants, or the use thereof to alcohol-based organic solvents, ketone-based organic solvents, hydrocarbon-based organic solvents, water, or the like. This invention relates to a deodorant characterized by containing as an active ingredient an essential oil extracted with a mixed solvent of.

This deodorizer is easy to manufacture industrially and can be used for refrigerators, garbage, etc.
It is used as a deodorizer to clean all kinds of odors, such as indoor air purification.

[Prior Art] Conventionally, in the field of deodorants, activated carbon in the form of powder, granules, and tablets has been mainly used, but organic or inorganic thickening gelling agents and deodorants, such as tea leaves, have also been used. A gel-like material is used, which is a combination of extracts.

In addition, the above-mentioned tea extracts and chlorine-based deodorants, such as chlorine dioxide, are used in liquid form, filled in bottles or aerosol cans.

Activated carbon is porous and spongy, so it has a very large surface area, said to be 1 * 200 m2 per gram.It is called an adsorbent because it absorbs and removes odors on this large active surface. Also called.

Deodorizers made from tea extract act directly on odorous substances,
It is known as a deodorant that removes odors by neutralizing or oxidizing odorous substances. Chlorophyll is a typical deodorant belonging to this series.

A deodorant made of chlorine dioxide is known as a deodorant that directly acts on odorous substances to oxidize and remove odors.

[Problem to be Solved by the Invention J] However, all of these conventional deodorants have a weak deodorizing effect, and consumers have desired a deodorant with a stronger deodorizing effect.

Activated charcoal has a strong deodorizing effect compared to plant tea extracts, but it is not completely satisfactory.

Tea extract, which is a liquid deodorant, has very weak deodorizing power, and chlorine dioxide, which is a chlorine-based deodorant, has a strong deodorizing effect compared to tea extract, but it has a chlorine odor and is very expensive. ζ in concentrated products
It also has the disadvantage of being at risk of explosion.

[Means for Solving the Problems] In view of these circumstances, the present inventors have developed a method that has a high deodorizing effect and
As a result of extensive research in order to obtain deodorants that are good in terms of odor and safety, we have found that crushed products of cypress plants or alcohol-based organic solvents, ketone-based organic solvents, hydrocarbon-based organic solvents, etc. The inventors have discovered that a deodorant containing essential oils as active ingredients extracted by water or a mixed solvent thereof has excellent deodorizing effects, has a good odor, and is highly safe, leading to the creation of the present invention. .

That is, the present invention is a deodorant characterized by containing a crushed product of a plant of the Cupressaceae family or an essential oil obtained therefrom as an active ingredient.

The types of plants of the Cupressaceae family in the present invention include arborvitae,
Examples include Japanese cypress, Spanish mackerel, Asunaro, Lawson cypress, juniper, Ibuki, and Japanese cypress, and these can be used singly or in combination.

Suitable parts include leaves, fruits, stems, roots, etc.

In the present invention, the solvent used to extract essential oil from the above raw materials includes, for example, alcohol-based organic solvents such as methanol, ethanol, propanol, isopropanol, propylene glycol, and 1,3-butylene gellicol, and ketone-based solvents such as acetone and methyl ethyl ketone. Examples include organic solvents, hydrocarbon organic solvents such as pentane, hexane, and octane, water, and mixed solvents thereof, and methanol, ethanol, pentane, and hexane have a high extraction rate of essential oils and have strong deodorizing power. .

When extracting the essential oil of the deodorant of the present invention from the above raw materials, when using an organic solvent system, it is efficient to use, for example, a Soxhlet extraction device, and when using water or a mixed solvent with water, it is efficient. Generally, a steam distillation device is used.

In either case, the extraction time is preferably about 10 to 20 hours.

In the present invention, when the above-mentioned active ingredient is used as a deodorant, various dosage forms can be selected as appropriate depending on the purpose of deodorization. For example, when used as a deodorizer for refrigerators, if the crushed raw material or extract is dissolved or dispersed in water and combined with a gelling agent, the contents will remain intact even if the container falls over in the refrigerator. It is convenient and does not spill. Examples of the gelling agent include metal soaps, agar, organic metal compounds such as carrageenan, montmorillonite, various clay minerals, and inorganic compounds such as silica gel, which are used as appropriate depending on the purpose of thickening and gelling. When used as a deodorizer for garbage and indoor air purification, liquid or aerosol forms are suitable, including the method of use.

The required amount of crushed products of Cupressaceae plants or the essential oil obtained from them varies depending on the amount of odorous components and the place of use, but the lower limit is about 0.001 to 0.000% of the total amount of odorous components.
Approximately 601% by weight is sufficient, and for example, when blended into a deodorant, it is preferably blended in an amount of approximately 0.1 to 20% by weight based on the composition.

The deodorant of the present invention exhibits particularly excellent deodorizing effects against odorous components such as hydrogen sulfide, methyl mercaptan, and trimethylamine, but is also effective against all other types of malodors.

Although the mechanism of action of the deodorant of the present invention is not clear, it is likely that pinene, terpene hydrocarbon alcohols such as eudesmol and ermol, saturated or unsaturated aldehyde compounds, etc. are present in the leaves and insides of cypress plants. Since a large number of units are installed, it is thought that, for example, it is effective against foul-smelling methyl mercaptan through the addition reaction of the above-mentioned compound, and against foul-smelling amine compounds through the reaction of alcohols, aldehydes, etc. In addition, the above-mentioned active ingredients have an absorbing effect that envelops these malodorous substances, and it is presumed that the effect is exerted through a complex combination of these substances.

[Extraction example] The extract in the present invention was extracted according to the following extraction example.

Extraction Example 1 A crushed product of 100 g of arborvitae leaves was extracted with 150 ml of ethanol using a Soxhlet extractor, and the ethanol was removed to obtain 1.3 g of essential oil.
