DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an insect repellent for a body that prevents insects such as mosquitoes, mites, and gnats from leaning on the body.

Means for Solving the Problems As a result of intensive studies, the present inventors have found that the odor emitted by citronella oil does not attract insects, and completed the present invention.

The present invention solves the above-mentioned problems by providing a body insect repellent having the following characteristics. The insect repellent for a body according to the first invention of the present application contains citronella oil and can be applied.

The insect repellent for a body according to the second aspect of the present invention is at least one selected from the group consisting of petrolatum, a copolymer of propylene oxide and ethylene oxide, and a derivative of a copolymer of propylene oxide and ethylene oxide. As a main component, which contains citronella oil and can be applied.

The citronella oil included in the body insect repellent of the present invention is an oil extracted from citronella grass, also called lemongrass, which is a wild grass of the Poaceae family. The amount of this citronella oil is preferably about 1 to 5% by weight of the whole.
When the content is less than 1% by weight, the effect of repelling insects is diminished. On the other hand, when the content is more than 5% by weight, the fragrance is too intense rather than refreshing. Because.

Vaseline, a copolymer of propylene oxide and ethylene oxide, and a derivative of a copolymer of propylene oxide and ethylene oxide may be used alone or in combination of two or more selected from them. Also, the amount of these compounds
About 60 to 99% by weight of the whole is preferable. When the content is 60% by weight or less, the composition is easily washed off with water after the application, and when the content is 99% by weight or more, the insect repelling effect is reduced.

The body insect repellent of the present invention can be composed of the citronella oil and vaseline, a copolymer of propylene oxide and ethylene oxide, or a derivative thereof. Can include camphor, eucalyptus in Japan, menthol in Japan, limonene, and the like.

In addition, even when the composition was applied to the body in the same manner as above, even when water was applied from above, the insects did not approach the body for about 20 hours.

[0012]

As described above, when the present invention is applied to the body or the like, insects can be repelled and the insects can be prevented from approaching the body. In addition, the insect repellent effect can be maintained for a long time.
Vaseline, a copolymer of propylene oxide and ethylene oxide, and at least one selected from the group consisting of a derivative of a copolymer of propylene oxide and ethylene oxide as a main component, which contains citronella oil. if,
