Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gel-type deodorant, and more particularly to a gel-type deodorant containing a deodorant, a water-repellent inhibitor, agar and water, which has a significantly improved water-repelling property. Regarding deodorant.

2. Description of the Related Art In recent years, the demand for odor control has been increasing with the improvement of living standards. In addition to deodorants for toilets and garbage, deodorants for refrigerators, deodorants for living rooms, entrances, and geta. Various deodorants such as box deodorants, car deodorants, and pet deodorants are commercially available.

Conventionally, liquid deodorants, solid deodorants, and gel type deodorants have been provided as deodorants.

Among these deodorants, the liquid deodorant is used by directly injecting it into a toilet bowl or spraying it in a mist form. Since this liquid deodorant can be directly applied to the source of bad odor, it has an excellent odor control effect, but has a shortcoming that the deodorization effect is obtained only within a certain period after use, because the effect is not persistent. .

It has been considered that the liquid deodorant is put into a container and gradually volatilized to achieve long-term connectivity for deodorizing effect. In this case, however, when the container is collapsed, There is a drawback in that there is a risk that the deodorant will flow out and stain the surroundings.

On the other hand, if the solid deodorant or gel type deodorant does not have the above-mentioned problems, it is put in a container and the deodorant component is gradually vaporized to obtain a long-lasting effect. be able to.

However, the solid deodorant has some problems in the sustained release of the deodorant component, and in many cases, a sufficient deodorant effect cannot be obtained until the deodorant itself is completely lost. Recently, efforts are being made to develop gel-type deodorants.

The conventional gel type deodorant is generally manufactured by gelling the deodorant agent and the water separating agent with water and agar. In addition, a gelling agent based on a carrageenan is also common, but when the amount of the deodorizing agent added is large, there is a problem in terms of gel strength or production.

[0009]

However, the conventional gel-type deodorant described above has a drawback that the water in the gel separates and accumulates on the gel-type deodorant with the lapse of storage time.

Various studies have been made to prevent the water separation and stabilize the gel, and the applicant of the present invention has previously incorporated locust bean gum to enhance the strength of the gel and improve the stability. A deodorant has been proposed (JP-A-4-1222).
62).

According to the gel type deodorant described in the above-mentioned Japanese Patent Application Laid-Open No. 4-122262, although the gel can be stabilized,
When trying to improve the deodorant effect by increasing the content ratio of the deodorant in the gel deodorant, the higher the ratio of the deodorant in the gel deodorant is, the more the deodorant is separated from the water. However, the current situation is that further improvement for prevention of water separation is desired.

The present invention has been made in view of the above conventional circumstances, and in a gel type deodorant containing a deodorant, a water separating agent, agar and water, prevents water separation with time and stabilizes the gel. An object is to provide a gel type deodorant having improved properties.

[0013]

The gel type deodorant according to claim 1 is a gel type deodorant containing a deodorant, a water separating agent, agar and water, wherein starch is used as a water separating agent. Characterize.

The gel type deodorant according to claim 2 is characterized in that, in the gel type deodorant according to claim 1, the starch is mung bean starch.

The gel type deodorant of claim 3 is the gel type deodorant of claim 1 or 2, wherein agar is 1.0 to 3.0% by weight and starch is 0.3 to 1.0% by weight. It is characterized by containing.

The present invention will be described in detail below. In addition, below, the ratio of each component shows the ratio in the obtained gel type deodorant.

In the present invention, plant extracts, organic acids, aldehydes and the like can be used as the deodorant,
The content ratio is 0.1 in order to obtain a good deodorizing effect.
It is preferably about 35% by weight.

As the starch used as the water separating agent, mung bean starch, rice starch, corn starch and the like can be used, and among these, mung bean starch is particularly preferable. The content ratio of the water separation inhibitor is appropriately determined depending on the content ratio of the deodorant and water of the gel-type deodorant to be obtained so that a sufficient water separation preventing effect can be obtained. It is preferably 0.3 to 1.0% by weight. When the proportion of the water-repellent agent is higher than the above proportion, the gel strength is remarkably lowered or the water-repellent phenomenon occurs, and when the proportion is small, the sufficient water-repellent preventing effect cannot be obtained.

Water constitutes the main component of the gel-type deodorant, and serves as a medium for adjusting the hardness and viscosity of the gel-type deodorant to be obtained and for volatilizing the deodorant. However, if the proportion is large, the stability of the gel will be poor and it will become a liquid easily, and if it is small, the volatility of the deodorant will be poor. Normally,
When the water content is 55 to 90% by weight of the gel type deodorant, good gel stability and deodorant volatility can be obtained.

Agar is blended in order to form water into a gel form. If the ratio is too small, it does not become a gel form, and if it is too large, the gel density becomes high and the volatility of the deodorant drug is poor. Become. Therefore, the content of agar is preferably 1.0 to 2.0% by weight.

In the gel type deodorant of the present invention, in addition to the above deodorant agent, starch, agar and water, the following additives can be blended if necessary.

1.0 to 10% by weight of a fragrance such as a fragrance. 1.0 to 5.0% by weight of a softening agent or a suspending agent such as propylene glycol and glycerin. 0.1 to 1.0% by weight of a preservative such as sodium benzoate and 2-nitro-2-bromo-propanediol.

Such a gel type deodorant of the present invention is prepared by suspending, for example, agar and starch in water and then heating and dissolving at 90 to 100 ° C. Next, the mixture is cooled to 60 ° C., and a deodorizing agent or the like is added and mixed. Further, it can be easily manufactured by casting it in a mold, gelling it, and then removing from the mold.

The gel-type deodorant of the present invention thus obtained is put in a container having an opening to remove the deodorant for toilets, garbage, refrigerators, and deodorants for living rooms. Various deodorants such as deodorants for doors, clogs, shoe boxes, car deodorants, pet deodorants, etc. Due to the volatility of the odor agent, an excellent deodorizing effect can be obtained.

[0025]

[Action] Starch is used in combination with agar, which is a gelling agent,
Improves gel strength and effectively prevents water separation from gel deodorant.

As the starch, mung bean starch is particularly effective. Further, the agar content is preferably 1.0 to 3.0% by weight, and the starch content is preferably 0.3 to 1.0% by weight.
