Detailed Description of the Invention

[0001]

Field of the Invention The present invention relates to a detergent composition, and more particularly, to a detergent composition that is compatible with both pest repellent and detergency, and a sheet substrate impregnated with the detergent composition. The cleaning sheet thus formed.

[0002]

2. Description of the Related Art Conventionally, N, N-diethyl-m-toluamide (hereinafter referred to as "DE" has been used as a repellent against insects such as mosquitoes.
(Hereinafter sometimes abbreviated as “ET”) and natural essential oils such as citronella oil, lemon eucalyptus oil, and geraniol are known and put to practical use.

Further, in a building such as a general house, a screen door is used for the purpose of preventing harmful insects such as mosquitoes from entering the building, but when a complete effect of preventing harmful insects cannot be obtained. There are also many. For this reason, it has been attempted to enhance the pest repellent effect by using a pest repellent on an exposed outdoor portion such as a screen door or a window frame.

However, when DEET, for example, is used as the pest repellent, there is a problem that the base material is damaged depending on the material of the object to be used. When a natural essential oil such as citronella oil was used, the damage to the base material was small, but a sufficient repellent effect could not be obtained in some cases.

[0005] On the other hand, screen doors and the like are usually not frequently maintained, so it is desirable that pest repellent and cleaning can be performed at the same time. Further, since the screen door and the like are exposed outdoors, dirt and the like due to oily substances contained in the atmosphere are likely to adhere. Therefore, the cleaning composition is required to exhibit an excellent cleaning effect against such stains.
