Description

Technical Field

[0001] The invention relates to the field of daily chemical products, in particular to an electric mosquito-repellent incense liquid with plants and a preparation method thereof. Background Art

[0002] Natural plants are widely used in cosmetics because they are green, environmentally friendly and safe. In particular, flower petals are directly added to cosmetics to form petal lotions, petal masks, etc. This not only demonstrates the efficacy of plant active ingredients, but also gives the product a natural concept and meets consumers' demand for exquisite appearance.

[0003] At the same time, natural plants have many ingredients, generally containing volatile oils, terpenes, coumarins, pigments, etc. These natural ingredients, such as natural pigments and natural essential oils, make plants present various colors and smells; some plants also have insecticidal, bactericidal, insecticidal synergistic and other functional ingredients, such as azadirachtin, cinnamon oil, sassafras oil, etc. Therefore, if natural plants can be used in mosquito coils, their natural ingredients can be used to kill insects and better meet people's pursuit of natural and green. However, since natural plant ingredients contain unsaturated bonds, they are easily decomposed and oxidized under air, temperature, light and other conditions, thereby losing their activity or function, so their application is limited.

[0004] In addition, the retention technology of plant ingredients in the prior art is mainly concentrated on the petals, and because most cosmetics are water-based systems, their retention technology is basically water-based preservation technology, and the corresponding preserved ingredients are mainly care ingredients. At present, mosquito-repellent liquid mainly uses solvent oil, effective ingredients, flavors and other ingredients, and is equipped with a heater to play a mosquito-repellent role. If more natural plant extracts are directly added to it, it is easy to decompose and oxidize, thus becoming ineffective; and the above-mentioned water-based system preservation technology for cosmetics is not applicable to this oily system. Summary of the invention

[0005] In view of the above problems, the present invention provides an electric mosquito-repellent liquid with plants. The plants in the electric mosquito-repellent liquid can retain their shape, color and freshness for a long time, thereby improving the product appearance of the electric mosquito-repellent liquid. The effective ingredients in the plants can be slowly released along with the heating of the electric mosquito-repellent liquid, thereby improving the insecticidal effect and giving the electric mosquito-repellent liquid a natural fragrance and other auxiliary functions (such as sterilization).

[0006] In order to achieve the above object, the present invention provides an electric mosquito-repellent liquid with plants, the electric mosquito-repellent liquid comprising plants and mosquito-repellent liquid, and the preparation method of the plants comprises the following steps: taking 5-20 parts of flowers, leaves, stems or roots, soaking them with 25-70 parts of soaking liquid, drying, soaking them with dearomatized solvent oil, and dehydrating;

[0007] The soaking liquid includes the following raw materials in percentage by weight:

[0008] Ethanol 10-20%

[0009] Soaking antioxidant 0.1-2%

[0010] Soak in UV protection agent 0.01-0.05%

[0011] Water balance;

[0012] The mosquito-repellent incense liquid comprises the following raw materials in parts by weight:

[0013] Insecticidal ingredients 0.03-0.8 parts

[0014] Mosquito-repellent liquid dearomatized solvent oil 21-38 parts

[0015] 1.5-10 parts vegetable oil

[0016] Ester solvent 0-1.2 parts

[0017] Synergist 0.03-0.4 parts

[0018] Antioxidant in mosquito coil liquid 0.06-1.2 parts

[0019] 0.0003-0.012 parts of anti-ultraviolet agent in mosquito coil liquid.

[0020] The inventors found in the research process that if the plant is directly added to the mosquito-repellent liquid, because it is directly exposed to light and is affected by subsequent heating, the components in the plant will be damaged and ineffective, and the shape and color of the plant cannot be maintained. At the same time, because the electric mosquito-repellent liquid is an oily system, if you want it to be able to lastingly retain its shape, color, and freshness in the mosquito-repellent liquid, the key is to solve the problem of stable preservation of the plant in the oily system. Therefore, the present invention adopts the above-mentioned preparation method and soaking liquid to pre-treat the plant, so that the water-soluble substances and alcohol-soluble substances in the plant are removed, and after soaking in the above-mentioned soaking liquid composed of ethanol, antioxidants, anti-ultraviolet agents, and water, and drying the water, the oil-soluble substances are preserved, and the appearance and color of the plant will not be destroyed.

[0021] At the same time, the inventor adopts the above raw materials to prepare mosquito-repellent liquid. After the solvent oil and the plant oil are mixed, the oil-soluble substances in the plant can be gradually dissolved and mixed with the components of the mosquito-repellent liquid. After the mosquito-repellent liquid is subsequently heated by a heater, the effective ingredients in the plant can be slowly released together with the insecticidal components of the mosquito-repellent liquid.

[0022] In one embodiment, the soaking antioxidant comprises at least one of the following raw materials: tea polyphenols, L-ascorbyl palmitate, D-isoascorbic acid and its salts, phytic acid, disodium ethylenediaminetetraacetic acid, propyl gallate, oligomeric proanthocyanidins, rosmarinic acid, lipoic acid, methionine, or carnosine;

[0024] The above-mentioned immersion antioxidant adopts a water-soluble antioxidant, and the immersion anti-ultraviolet agent adopts a water-soluble anti-ultraviolet agent.

[0025] In one embodiment, the insecticidal component includes at least one of the following raw materials: cypermethrin, tetrafluthrin, transfluthrin, pralothrin, metofluthrin, tetrafluthrin, or Es-bioallethrin.

[0026] In one embodiment, the mosquito-repellent incense liquid dearomatized solvent oil is a C12-C16 alkane solvent, and the mosquito-repellent incense liquid dearomatized solvent oil is odorless.

[0027] In one embodiment, the vegetable oil comprises at least one of the following raw materials: palm oil, peanut oil, soybean oil, or linseed oil.

[0028] By using the above-mentioned vegetable oil, the oil-soluble substances in the plants can be effectively dissolved, so that the components in the plants can be slowly released along with the heating of the electric mosquito-repellent liquid.

[0029] In one embodiment, the ester solvent includes at least one of the following raw materials: isopropyl myristate, diisopropyl adipate, tributyl citrate, or acetyl tributyl citrate.

[0030] In one embodiment, the synergist comprises at least one of the following materials: piperonyl ether, dibutyl maleate, diethyl maleate, synergist amine, or synergist phosphine.

[0031] In one embodiment, the mosquito coil liquid antioxidant comprises at least one of the following raw materials: antioxidant 1135, butylated hydroxyanisole, butylated hydroxytoluene, tocopherol, tert-butylhydroquinone, or flavonol;

[0032] The anti-ultraviolet agent of the mosquito-repellent liquid comprises at least one of the following raw materials: benzophenone-3, benzophenone-4, benzophenone-5, 3-benzylidene camphor, trimethylcyclohexyl salicylate, isopentyl p-methoxycinnamate, ethylhexyl salicylate, or diethylaminohydroxybenzoyl hexyl benzoate.

[0033] The above-mentioned mosquito-repellent liquid antioxidant adopts an oil-soluble antioxidant, and the mosquito-repellent liquid anti-ultraviolet agent adopts an oil-soluble anti-ultraviolet agent.

[0034] In one embodiment, the preparation method of the plant comprises the following steps: taking 5-20 parts of flowers, leaves, stems or roots, soaking them in an soaking liquid at 35-60°C for 2-24 hours; drying them at 50-80°C for 4-8 hours until the water content of the plants is 10-20%; soaking them in a dearomatized solvent for 0.5-2 hours, and removing the water at 85-105°C;

[0035] The dearomatized solvent oil is a C12-C16 alkane solvent, and the dearomatized solvent oil is odorless.

[0036] The invention also provides a method for preparing the electric mosquito-repellent liquid, comprising the following steps: weighing raw materials of the mosquito-repellent liquid, mixing, and adding plants to obtain the mosquito-repellent liquid.
