Description

Skin-friendly and powerful anti-mosquito composition and anti-mosquito spray

technical field

The invention relates to a mosquito repellent, in particular to a skin-friendly and powerful anti-mosquito composition and an anti-mosquito spray.

Background technique

The harm of mosquitoes is well known. After being bitten by mosquitoes, not only will it be painful and itchy, but what is more serious is that mosquitoes can transmit diseases such as malaria, filariasis, Japanese encephalitis and dengue fever. Therefore, a good mosquito repellent product is particularly important in summer.

Because mosquitoes mainly target human odors, such as exhaled carbon dioxide or body surface volatiles, and mosquito repellent is to spray a barrier on the body, which interferes with the chemical sensors of mosquito antennae on human body surface volatiles. Induction, so that people avoid mosquito bites. There are four common insect repellents: DEET, oil of lemon eucalyptus, icaridin, and imonine. DEET is a widely used insecticide that is sprayed on the skin or clothing to avoid insect bites by blocking the 1-octen-3-ol of insect olfactory receptors, however, because of the It is highly irritating, and DEET cannot be used in direct contact with the skin. Lemon eucalyptus oil is an extract of Australian eucalyptus. Research results have shown that the maximum protection time of lemon eucalyptus oil for mosquitoes is shorter than that of DEET. Children under 3 years old are usually prohibited from using mosquito repellent containing lemon eucalyptus oil. agent. Icaridin is also called Hydroxyphenidate, and its single or compound preparation will not cause damage to common home decoration materials, including plastics, paints, metal decorative foils and paints, and its effectiveness is better than that of DEET. Yimening, also known as mosquito repellent, is a broad-spectrum and highly effective insect repellent. It has a good repellent effect on mosquitoes, flies, lice, etc. It has a long repellent effect and can be used under different climatic conditions. At the same time, Yimening has stable chemical properties, high thermal stability and high sweat resistance, and has good compatibility with commonly used cosmetics and pharmaceuticals. It can be made into solutions, emulsions, ointments, coatings, Special repellent agents such as jelly, aerosol, mosquito coils, and microcapsules can also be added to other products or materials (such as toilet water) to make them repellent.

The use of some plants that emit special odors to repel mosquitoes has a long history. It is recorded in the "Book of Songs" and other documents. The significant advantages of plant repellents are green, safe and harmless to humans. However, the existing plant repellents are effective. Short duration.

With the development of society, people pay more and more attention to the safety of mosquito repellent products. At present, there is no good mosquito repellent product, which combines high-efficiency synthetic mosquito repellent with natural plant mosquito repellent ingredients, and at the same time adds skin-friendly or other functional ingredients, while satisfying long-term mosquito repellent effect, endows the product with Green environmental protection, healthy skin care and other functions.

Contents of the invention

To solve the above problems, one of the objects of the present invention is to provide a skin-friendly and effective mosquito repellent composition.

The second object of the present invention is to provide a preparation method of a skin-friendly and effective anti-mosquito composition.

The third object of the present invention is to provide a skin-friendly and powerful anti-mosquito spray.

In order to achieve the above object, the present invention adopts the following technical solutions:

A skin-friendly and effective anti-mosquito composition, comprising the following raw materials by weight ratio:

Imonen 10-30%,

Plant Extract Fragrance 1-20%,

The balance is skin care agent.

Preferably, the skin care agent is one or a mixture of tea tree extract, calendula extract, allantoin, chamomile extract, and aloe.

Preferably, the plant extract fragrance includes at least one of citronella oil, geraniol, eucalyptus oil and lavender oil.

Further preferably, the skin-friendly and effective anti-mosquito composition includes the following raw materials by weight ratio:

A preparation method of a skin-friendly and powerful anti-mosquito composition, comprising the following steps: adding Imonin, plant extract fragrance and skin care agent into a reaction kettle, stirring and mixing evenly at room temperature at a stirring speed of 800-1000rpm, That's it.

A skin-friendly and powerful anti-mosquito spray comprises a spray device and the above-mentioned skin-friendly and strong anti-mosquito composition; the spray device includes a container containing the above-mentioned deodorant composition, an actuating device and a sealing cover.

Preferably, said container is made of PET.

Preferably, the actuating device is a manual spray pump mechanically driven by pressing the spray head.

More preferably, the structure of the spraying device is as shown in Figure 1, the container 1 contains the anti-mosquito composition of the present invention, and by pressing the actuating device 2, the mist of the anti-mosquito composition is evenly sprayed on the skin of the human body When not in use, the sealing cover 3 can effectively prevent the volatilization of the anti-mosquito composition.

At present, the anti-mosquito products on the market need to use the hygienic pesticide DEET, which is highly toxic and not suitable for children. However, the anti-mosquito product of the present invention, which uses "Imonin" as the main raw material, is directly sprayed on the skin, and its repellent The mosquito principle is to interfere with the mosquito's sensor and affect its perception of the host, so that the host will be protected from mosquitoes and achieve the effect of repelling mosquitoes. Plant-extracted mosquito repellent fragrance, combined with Imonin, improves the mosquito repellent effect and effective time of mosquito repellent, and the product also emits a refreshing aroma. The present invention uses imonin and plant-extracted spices to be compatible, and the effective time of anti-mosquito is more than 6 hours, and the smell is refreshing, and the mist droplets of the manual spray pump are uniform, and the handle is comfortable, which is more convenient for customers to use.

Beneficial effects of the present invention

1. The anti-mosquito composition of the present invention is compatible with Imonin and plant-extracted spices, which has a long-term mosquito repellent function and a refreshing breath;

2. The anti-mosquito composition of the present invention is added with a skin-friendly agent, which can care for the skin while repelling mosquitoes, and is non-irritating, breaking through the single functionality of the mosquito repellent;

3. The spraying device of the anti-mosquito spray of the present invention adopts a manual spray pump, and the spray droplets are uniform, easy to press, and more convenient for customers to use.

1. Test method: Put 300 test mosquitoes in the mosquito cage. The tester wears protective gloves and exposes 40*40mm of skin on the back of the hand. He sticks into the mosquito cage and stays for 2 minutes. After close observation, he finds that the test mosquitoes stop and land. Before piercing the skin, shake the arm to drive it away. It is recorded as one test mosquito landed. The test personnel and the test mosquitoes in the cage with more than 30 test mosquitoes come to land are qualified for attack. The person and the cage Test mosquitoes can be tested for repellency.

Select more than 4 people who have passed the attack test (half male and half female, and should not drink alcohol, tea or coffee, or use products containing flavors before and during the test), and draw a 50*50cm area on the back of their hands To test the skin, apply the repellent to be tested evenly at a dose of 1.5ml/cm ² on one hand, expose 40*40mm of it, and tightly cover the rest, and the other hand is a blank control. Apply the repellant for 2 hours, put your hand into the mosquito cage with qualified attack power, stay for 2 minutes, observe whether there are mosquitoes coming to stop and suck blood, and then test every 1 hour, as long as one mosquito comes to suck blood, it will be judged If the repellent fails, record the effective time (h) of the repellent. Each time a control test is done with the control hand, the test insects with qualified attack power can continue the test, and the test insects with unqualified attack power need to replace the qualified test insects and then carry out the test.
