Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a deodorant containing permanganate as an active ingredient. This deodorizer is widely used in, for example, food shelves, cupboards, living rooms, shoe cabinets, wet rooms, toilets, cars, etc.

[Conventional technology]

Conventionally, activated carbon in the form of powder, granules, and tablets has been mainly used in the field of deodorants, but there are also gel-like products that combine organic or inorganic thickening gelling agents and deodorants, such as plant extracts. Since activated carbon is porous and spongy, it has a very large surface area, said to be as much as 12'00 m1 per gram, and this large active surface absorbs odors. It is also called an adsorbent because it removes it.

On the other hand, deodorizers made from plant extracts are known as deodorizers that directly act on odorous substances and remove odors by neutralizing or oxidizing them.

Chlorophyll is a typical deodorizing agent in this family. These deodorants are combined with thickening gelling agents,
It is used in gel form. In this case, organic compounds such as metal soaps, natural polymeric substances such as polysaccharides and casein, and synthetic polymeric substances such as male lioxyethylene and acrylic acid dilimer can be used as the thickening agent. As inorganic compounds, various clay minerals such as montmorillonite, silica, etc. are used, and the type of thickening gelling agent is appropriately selected depending on the purpose.

[Inventiveness? Problems to be solved]

However, all of these conventional deodorants have a weak deodorizing effect, and consumers have desired a deodorizing agent with a stronger deodorizing effect.

Activated charcoal has a strong deodorizing effect compared to gel deodorants containing plant extracts, but it is not completely satisfactory, and because it has a pitch-black appearance, it cannot reach the end point of its deodorizing effect, that is, the point at which it is used. Another drawback is that it is not clear.

In view of these circumstances, the present inventors have discovered that the deodorizing effect is high,
As a result of extensive research in order to obtain a deodorant that is safe for the human body and has a clear end point, we found that permanganate has an excellent deodorizing effect out of many raw materials. It was also found to be highly safe. By further adjusting the content of permanganate in the deodorant, the color changes from a beautiful pale pink to purple while the deodorant is effective, but when the deodorizing effect wears off, the color changes from pale brown to pale brown. It has been discovered that the end point can be easily determined from the change to brown (K), and the present invention has been completed. That is, the present invention uses permanganate as an active ingredient in the range of 0.001 to 5.0
This is a deodorant containing ft% by weight.

The permanganate salt used in the present invention is a raw material listed in the Japanese Pharmacopoeia, and is an extremely safe raw material that is widely used in external preparations and deodorants. Permanganate itself is dark purple columnar crystals that are not aesthetically pleasing, and even if it reacts with odorous substances, the appearance color does not change significantly, so the end point is unknown. By mixing it with a solid carrier or adsorbing it onto these carriers and diluting it, it becomes a pale pink to purple powder that is beautiful in appearance. When this powder is brought into contact with an odorous substance such as methyl mercagutan, which belongs to a sulfur compound, or trimethylamine, which belongs to a nitrogen compound, the odorous substance immediately becomes odorless. Furthermore, when the deodorizing effect wears off, the color changes from light brown to brown.

This allows the end point of the deodorizing effect to be easily identified.

In the present invention, the content of permanganate needs to be in the range of 0.001 to 50% by weight based on the total amount of the deodorant. If the concentration is less than 0.001% by weight, the change in color tone is good, but the deodorizing effect is weak and it is not practical. Also, if it exceeds 50% by weight, the color tone of the exterior will be too dark, so it may be difficult to change the color tone. The drawback is that it is not well understood.

The deodorant base (carrier) for diluting permanganate may be any light-colored solid, with white ones being particularly preferred. As examples of these, porous inorganic powders are preferred. As a base material, for example, silica, alumina,
Examples include zeolide, clay, talc, mica, calcium phosphate, calcium carbonate, gold powder, coral powder, coral sand, shoulder board polymeric substances, inorganic polymeric substances, paper, cloth, nonwoven fabric, wood, and the like. Among these, the powdered substances may be processed and used in the form of granules, beads, and tablets, and the permanganate may be adsorbed before processing, or may be adsorbed after processing.

The base (carrier) and permanganate may be simply mixed together, or the base may be adsorbed and impregnated with permanganate.

When mixing, it is preferable that the permanganate crystals be ground as finely as possible and spread uniformly in the carrier. A conventional method may be used to adsorb or impregnate the carrier with permanganate. Examples are listed below.

(Part 1) After mixing permanganate and powder, pulverize and mix using a powerful powder lifter. Mere mixing will only yield a powder with an external color tone of the raw material color of the powder or a powder with a slightly dull raw material color, and the desired end point cannot be reached. (Part 2)
Dissolve the permandate in a solvent and apply it to the adsorbent.

Examples of the solvent include water, alcohol, acetone, etc., and this method allows the powder to be adsorbed onto cloth, wood, etc.

In the present invention, in addition to the above-mentioned essential components, an appropriate amount of fragrance can be added.
