DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant composition having an excellent deodorizing effect on malodor generated from feces of pets and the like.

[0002]

2. Description of the Related Art As odorous substances generated from feces of pets and the like, there are ammonia, trimethylamine, and lower fatty acids such as butyric acid and propionic acid.

[0003] In general, physical deodorization methods,
Chemical deodorant method, biological deodorant method and sensory deodorant method, for example,
A method to remove malodorous components by using the adsorption action of activated carbon, a method to neutralize malodorous components using acids and alkalis, a method to decompose malodorous components by oxidation-reduction by a catalyst, And a method of masking with a fragrance, and various substances for that purpose have been devised.

[0004] However, these methods have the disadvantages that they are temporary in effect, only work on limited odorous substances, and require large-scale equipment. Therefore, satisfactory effects have not always been obtained. Therefore, development of a deodorant which can be easily used and has a long-lasting deodorizing effect has been demanded.

[0005]

As a deodorant which can be easily used, there is a type which is sprayed in a liquid state. However, existing deodorants are temporary, which deodorize against already generated malodors. Therefore, if the odor-causing substance remains, a new odor is generated, and no effect can be exhibited. For example, if urine and feces remain, urea in urine generates new ammonia due to urease of microorganisms in feces, which is ineffective.

Accordingly, it is an object of the present invention to provide a deodorant composition which has an immediate effect on a malodor generated from feces of a pet or the like and has a long-lasting effect.

[0007]

DISCLOSURE OF THE INVENTION The present inventors have developed a plant-derived substance having a quick-acting deodorizing effect by adding a urease inhibitor that suppresses the generation of new ammonia and a lipase that is esterified to lower fatty acids. The present inventors have found that by adding alcohol, a deodorant composition having an immediate effect and a long-lasting effect can be obtained, and the present invention has been completed.

[0008] That is, the present invention resides in a deodorant composition characterized by comprising at least one or more plant-derived substances having a deodorizing action, a urease inhibitor, a lipase, and an alcohol.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

[0010] There are various plant-derived substances having an immediate deodorizing effect which are used in the present invention.
Distillate obtained by distilling a dry powder of tea extract such as oolong tea, alder or alder (Japanese Patent Laid-Open No.
148235, hereinafter abbreviated as Arnas) and the like. The amount used varies depending on the plant-derived substance. For example, in the case of tea extract, it is 0.01% to 5%, preferably 0.1% to 2%, and in the case of Arnas, it is 10%.
-The remaining amount of the composition (used in place of water as a solvent), preferably 20% or more.

There are various urease inhibitors used in the present invention, and examples thereof include boric acid, tannic acid, p-benzoquinone, hydroquinone, hydroxamic acid, and thiourea. The amount used depends on the intensity of the urease inhibitory activity. For example, in the case of boric acid, it is 0.02% to 5%, preferably 0.5% to 3%, and in the case of tannic acid, it is 0.01%. 10%, preferably 0.5% to 5%, and in the case of p-benzoquinone, 0.001% to 0.2%, preferably 0.01% to 0.1%.
1%.

The lipase esterified to lower fatty acids used in the present invention can be widely selected from lipases having esterification activity. For example, lipase produced by a microorganism of the genus Candida, a kind of yeast. And the like (JP-A-9-225015). The use amount is preferably 0.001% to 10%,
More preferably, it is 0.01% to 1%. The alcohol includes lower alcohols such as ethyl alcohol, methyl alcohol, and propyl alcohol, but ethyl alcohol is preferable from the viewpoint of safety, and the amount of alcohol used is 2 to 20.
% Is preferred.

[0013] The deodorant composition of the present invention can be prepared in the form of a liquid, solid, paper, gel, paste, granule, or powder using appropriate known excipients, clathrates, carriers and the like as necessary. And various dosage forms such as granules. When the liquid is used, it can be used by a pump spray method, a spray spray method using a gas such as nitrogen gas or dimethyl ether, or the like. In addition, it can be used as a two-drug type in which lipase and other substances are separated and prepared as a ready-to-use type.

When the deodorant composition of the present invention is used, the existing malodor is deodorized with a plant-derived substance having a deodorizing effect, and the odor is reduced by urea in urine and urease of microorganisms in feces. Newly generated ammonia is suppressed by urease inhibitors, lower fatty acids are aroma by esterification with lipase and alcohol, and deodorant by masking malodorous components for a long time, which has immediate effect. , And can be deodorized continuously.
