Embodiment 1

[0035] The preparation of plant extract: get green Zanthoxylum bungeanum 25g, lavender 10g, rose 10g, Huoxiang 5g, peppermint 5g, after washing, draining, drying, pulverizing, after the obtained powder is passed through a 20-mesh sieve, add 55ml of deionized water, Using microwave-assisted extraction technology, control the microwave power to 100W, microwave extraction for 1 hour, and control the extraction temperature between 45-65°C. The extract is filtered to remove the filter residue, and the filtrate is the plant extract.

[0036] The plant extract obtained above, ethanol and deionized water are mixed according to the following weight percentages: plant extract 5%, ethanol (the volume percentage of ethanol is 40%-75%) 40%, and the rest is deionized water; canned , and finally obtain the mosquito repellent water.

Embodiment 2

[0038] Preparation of plant extract: Get 40g of green Zanthoxylum bungeanum, 20g of lavender, 20g of rose, 15g of Huoxiang, 15g of peppermint, wash, drain, dry and pulverize, after the powder obtained passes through a 20-mesh sieve, add 110ml of deionized water, Using microwave-assisted extraction technology, control the microwave power to 300W, microwave extraction for 2 hours, and control the extraction temperature between 45-65°C. The extract is filtered to remove the filter residue, and the filtrate is the plant extract.

[0039] The plant extract obtained above, ethanol and deionized water are mixed according to the following weight percentages: plant extract 1%, ethanol (the volume percentage of ethanol is 40%-75%) 75%, and the rest is deionized water; canned , and finally obtain the mosquito repellent water.

Embodiment 3

[0041] Preparation of plant extracts: Take 35g of green pepper, 15g of lavender, 15g of rose, 7.5g of patchouli, 7.5g of mint, wash, drain, dry, and crush the obtained powder through a 20-mesh sieve, add 80ml of deionized Water, using microwave-assisted extraction technology, control the microwave power to 200W, microwave extraction for 1.5h, and control the extraction temperature between 45-65°C. The extract is filtered to remove the filter residue, and the filtrate is the plant extract.

[0042] The plant extract obtained above, ethanol and deionized water are mixed uniformly according to the following weight percentages: plant extract 2.5%, ethanol (the volume percentage of ethanol is 40%-75%) 65%, and the rest is deionized water; canned , and finally obtain the mosquito repellent water.

Abstract

The invention provides mosquito repellent water containing green pepper extracts and a preparation method of the mosquito repellent water. The mosquito repellent water is prepared from components in percentage by weight as follows: 1%-5% of plant extract, 40%-75% of ethanol and the balance of deionized water, wherein the plant extract is prepared from raw materials in parts by weight as follows: 25-40 parts of green pepper, 10-20 parts of lavender, 10-20 part of roses, 5-15 parts of wrinkled gianthyssop herbs and 5-15 parts of mint with a method shown as follows: the raw materials are mixed, cleaned, drained, dried and crushed, the crushed powder is added to the deionized water in a material-water ratio and extracted with a microwave-assisted extraction technology, an extracting solution is filtered, and filtrate is the plant extract. The mosquito repellent water has the mosquito repellent effect and further has the efficacy of refreshing, restoring consciousness, cooling, relieving itching, inhibiting and killing bacteria, protecting skin against bite by insects and the like; besides, raw materials of the product are from plants, and the mosquito repellent water is safe, non-toxic and applicable to various crowds and various skin.

Description

technical field [0001] The invention belongs to the technical field of plant extraction and daily chemical industry, and particularly relates to a mosquito repellent water mainly composed of green zanthoxylum bungeanum extract and a preparation method thereof. Background technique [0002] Mosquito bites not only cause skin redness, itching and inflammation, but also may spread diseases, such as malaria, Gordon fever, filariasis and other diseases, which can be transmitted by mosquitoes sucking human blood, seriously threatening human health. [0003] At present, there are various kinds of mosquito repellent water on the market, but the main raw materials are mainly synthetic DEET, mosquito repellent and dimethyl phthalate, and these raw materials have certain toxicity to mammals. During the process, people will absorb toxic substances through the respiratory tract, digestive tract, etc. Long-term use of the above mosquito repellent water may induce asthma and other diseases...
