Description

TECHNICAL FIELD The present invention relates to a deodorant having a good deodorizing effect on methyl mercaptan and the like. More specifically, it removes halitosis, or is used at home or in a factory. The present invention relates to a deodorant that can effectively remove the offensive odor that is generated and is therefore suitable for oral use, household use, industrial use, and the like.

Conventional Problems and Problems to be Solved by the Invention Conventionally, sodium copper chlorophyllin has been known as an effective deodorant component, particularly as an effective component for removing halitosis, and is widely used in various oral compositions. However, when copper chlorophyllin sodium is added to an oral composition such as toothpaste in an amount capable of exerting an effective deodorizing effect on methyl mercaptan and the like, the color of the oral composition becomes very dark.

Further, it has been proposed to use various plants and solvent extracts thereof as deodorant active ingredients, but the deodorant effect against methyl mercaptan and the like is high, and it is safe to apply in the oral cavity. A high deodorant active ingredient is desired.

The present invention has been made to meet the above-mentioned demands, and an object thereof is to provide a deodorant having a high deodorizing effect on sulfur compounds such as methyl mercaptan and having high safety in use.

Means and Actions for Solving Problems The present inventors have conducted diligent studies to achieve the above-mentioned object, and as a result, specific seaweeds, that is, red seaweed, sawtooth molybdenum, hazelnut mottled moth, Nejimoku, narasamo, umitranoo,
Mamedawala, Yatsumatamok, Yoremoku, Isomok, Togemoku, Pea Moku, Futaemok, Hanezozo, Kurosozo, Cobusozo, Papirazoso and their solvent extracts have an excellent deodorizing effect on methylmercaptan and the like, and are more deodorant than copper chlorophyllin sodium. The present invention has been found to have a high odor effect, and can be suitably used as an active ingredient for deodorizing agents for oral deodorants, and also as an active ingredient for deodorizing purposes such as household and industrial purposes, and forms the present invention. It came to.

Hereinafter, the present invention will be described in more detail.

The deodorant of the present invention includes red moss, sawtooth molybdenum, moss molybdenum, Nejimoku, Narasamo, Umitranoo, Mamedawala, Yatumatamok, Yoremoku, Isomoku, Togemoku, Pea Moku, Futaemok, Hanezozo, Kurosozo,
A seaweed selected from Kobuzozo and papyrazozo and one or more solvent extracts of these seaweeds are blended as a deodorant active ingredient. These seaweeds and their solvent extracts have a deodorizing effect on sulfur compounds such as methyl mercaptan, and also have a deodorizing effect on ammonia-based and amine-based lower fatty acids, so toothpaste, mouthwash, mouthwash ， Used as an oral deodorant to remove bad breath such as chewing gum and candy, as well as cosmetics such as foot spray and hair rinse, for garbage, for refrigerators,
Deodorants for household use such as indoor use, in-car use, toilet use, etc. Industrial deodorizers that remove offensive odors generated from sewage treatment plants, fish processing plants, fish meal manufacturing plants, livestock manure and chicken manure drying plants, pulp mills, etc. Also used as such.

The extract obtained by the above extraction operation is usually mixed with the deodorant after distilling off the solvent, but in some cases, especially when the solvent is water, ethanol, etc., the solvent is distilled off. It is also possible to mix it in the deodorant without removing it.

Further, in the present invention, one kind of the extract is used alone or a mixture of two or more kinds as the deodorant active ingredient (a mixture of the extracts or one obtained by simultaneously extracting two or more kinds of seaweed).
Can be used as

The blending amount of the deodorant active ingredient of the present invention varies depending on the type of deodorant and the like, but when used for the oral cavity, 0.0001 to 5

Further, since the deodorant active ingredient of the present invention has a light color and weak odor, there are few problems in product formulation,
Furthermore, the safety in use is high.

Next, a production example (extraction example) of the deodorant active ingredient of the present invention and its deodorizing effect will be shown by examples.

[Production example]

To 20 g of the seaweed powder shown in Table 1, 200 ml of the extraction solvent was added, and the mixture was heated on water for 1 hour under reflux with heating with a cooling tube. Then remove the residue, add fresh solvent to the residue,
Reflux was carried out in the same manner as above. Further, separation of the residue and reflux were repeated, and extraction operation was performed three times in total.

The liquids were collectively concentrated under reduced pressure at 40 ° C. to obtain a paste-like or powder-like deodorizing active ingredient.

[Experimental example]

A test tube having a content volume of 20 ml was prepared by dissolving the deodorizing active ingredient obtained by the above method in water or ethanol in a solution (in the case of control, water or ethanol alone) was added to 0 ml.
The pH was adjusted to 7.2 by adding 1.5 ml of 1M phosphate buffer solution. Contains 1 μg / ml of methyl mercaptan 1
0.5 ml of a 0% by volume aqueous ethanol solution (0.5 μg of methyl mercaptan) was added, and a rubber stopper was immediately added, followed by vigorous stirring for 1 minute. Then, after standing still at 35 ° C. for 6 minutes, 5 ml of air was injected into the test tube by piercing a rubber stopper with a gas syringe for gas chromatography. After stirring vigorously for 30 seconds, 5 ml of gas was similarly sampled from the headspace with a gas syringe and immediately injected into the gas chromatograph to measure the integral count of methyl mercaptan.
The deodorizing rate was calculated from the following formula. As the gas chromatograph, 163 manufactured by Hitachi Ltd. was used.

C: Integral count of control S: Integral count of sample Plot the relationship between the deodorizing rate thus obtained and the sample amount in a semi-logarithmic graph to obtain the sample amount (MED) that gives a deodorizing rate of 100% This was evaluated as a deodorizing effect. The results are shown in Table 1.

From the results shown in Table 1, it was found that the seaweed powder of the present invention and the solvent extract thereof have an excellent deodorizing effect on methyl mercaptan.

The present invention will be described below with reference to examples, but the present invention is not limited to the examples.
