Abstract

PURPOSE:To provide a high effective deodorizing agent which is safe in using in oral cavity, for ex. mercaptan, by extracting fruit and/or leaf of olive with water and/or hydrophilic organic solvent consisting of low-grade alcohols, ketones, and esters. CONSTITUTION:Fresh olive leaves are immersed in methanol for one month, and the methanol solution obtained from these leaves is distilled in decompressed state to yield an extract. This extract has effect to deodorize methyl mercaptan etc. This deodorizing agent can take the for of liquid, air zol, spray, paste, or powder and grains. For ex. this is added to a tooth paste, which thus should have a good effect as an oral deodorant to prevent or remove oral odor.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a deodorant that has a good deodorizing effect on methyl mercaptan and the like. The present invention relates to a deodorizing agent that can effectively remove bad odors generated by food, etc., and can therefore be suitably used for oral, household, industrial, and other purposes.

[Problems to be solved by conventional techniques and inventions] Conventionally,
Copper chlorophyllin sodium is known as a deodorizing active ingredient, particularly as an active ingredient for removing bad breath, and is frequently used in various oral compositions. However, the problem with copper chlorophyllin sodium is that when it is added to oral compositions such as both layers in an amount that can exert an effective deodorizing effect against methyl mercaptan, etc., the color of the oral composition becomes very dark. There is. .

Therefore, it has been proposed to use various plants and their solvent extracts as deodorizing active ingredients (Japanese Patent Application Laid-Open Nos. 63-21061 and 63-24950). A deodorizing active ingredient that has a high deodorizing effect and is highly safe even when applied to the oral cavity is desired.

The present invention was made in response to the above-mentioned needs, and an object of the present invention is to provide a deodorizing agent that has a high deodorizing effect on sulfur compounds such as methyl mercaptan and is highly safe in use.

[Means and effects for solving the problem] The present inventors conducted intensive studies to achieve the above object, and as a result, the solvent extract of olive has an excellent deodorizing effect on methyl mercaptan, etc. It has a higher deodorizing effect than sodium copper chlorophyllin, and can be suitably used as an active ingredient in oral deodorants, as well as in household and industrial deodorizing applications. This discovery led to the present invention.

That is, the present invention provides a deodorant characterized by containing an olive extract as an active ingredient.

The present invention will be explained in more detail below.

The deodorant of the present invention contains as an active ingredient an extract of olive fruit and/or leaves with water and/or a hydrophilic organic solvent.

The olive used in the present invention is Olea erarobaea
Linnaeus (Olea europaea L, Oleaceae). The fruit is pickled in salt, vinegar, and sometimes sugar for cocktails, hors d'oeuvres, salads, confectionery, etc. Fresh fruit and/or fresh leaves are used in the present invention.

The extract refers to a solution obtained by extracting the olive with water or/and a hydrophilic organic solvent, condensing the solution, and distilling off the solvent. The hydrophilic organic solvent used for extraction is methanol.

Examples include lower alcohols such as ethanol, n-propatool, and impropatool, ketones such as acetone, methyl ethyl ketone, and methyl isobutyl ketone, and esters such as ethyl acetate.
Use a mixture of more than one species. When the solvent is distilled off, normal pressure may be used, but if the extract is heated to a high temperature, the deodorizing active ingredients in the extract may be decomposed, so distillation under reduced pressure is preferable. Considering extraction efficiency and ease of solvent distillation, methanol is preferable as an extraction solvent. Usually, a solvent-free extract is used when blending into a deodorant, but especially when the solvent is water, ethanol, etc., the extract may be used as it is in a deodorant without distilling off the solvent.

The extract obtained in this way is a green viscous substance with almost no odor, containing ammonia, amines, mercaptans, etc.
It exhibits a deodorizing effect on a wide range of malodorous substances such as hydrogen sulfide, but it exhibits an excellent deodorizing effect on mercaptans such as methyl mercaptan. Therefore, it is used as an oral deodorizer to remove bad breath in toothpaste, mouthwash, mouthwash, chewing gum, candy, etc., as well as for cosmetics such as foot sprays and hair rinses, food waste, and refrigerators. , household deodorizers for indoors, cars, toilets, etc., sewage treatment plants, fish processing plants, fishmeal manufacturing plants, livestock and poultry manure drying plants,
It is also used as an industrial deodorizer to remove bad odors emitted from pulp mills, etc.

Although it is not known which compound in the olive extract is responsible for these deodorizing effects, it is presumed that this is due to the secoiridoid glycosides contained in large amounts in the extract.

The form of use as a deodorant is not particularly limited, and various forms such as a liquid agent, an airzone spray, a paste form, and a powder form are possible. The amount added varies depending on the type of deodorant, but when used for the oral cavity, 0.
．． 001 to 50% (weight%, same below), especially 0.01
It is preferable to set it to 10%.

In addition, as other components of the deodorant of the present invention, appropriate components depending on the type, dosage form, etc. of the deodorant may be blended. For example, when the deodorizing active ingredient of the present invention is blended into an oral composition such as a toothpaste and used as an oral deodorant to prevent or remove bad breath, the toothpaste ingredients include dibasic calcium phosphate, calcium carbonate, and calcium pyrophosphate. , insoluble sodium metaphosphate, amorphous silica, crystalline silica, aluminosilicate, aluminum oxide, aluminum hydroxide, resin, and other abrasives (compounding amount usually 20 to 60% by weight)

〔Effect of the invention〕

The present invention uses olive, a plant, as a raw material, and uses water or/and
It is a natural deodorant extracted with a hydrophilic organic solvent and is a highly safe deodorant.

Since this deodorant itself is almost odorless, it can exert its deodorizing effect without causing disgust based on the odor. When olive fruit is used for food, the fruit is extracted with water to remove the bitter-tasting secoiridoid glycosides contained in it, and the extract is discarded. It can be said that it is an excellent invention from the point of view of effective use of materials.
