Description

Technical Field

[0001] This invention relates to the field of insect repellent formulations, and in particular to self-volatile liquid insect repellent formulations containing natural plants and their preparation methods. Background Technology

[0002] In indoor environments, mosquito infestations are often incredibly annoying. Hidden in corners, bathrooms, and bedrooms, they not only affect quality of life but can also pose health risks. Common mosquito repellents typically work by releasing insecticidal components through combustion, such as black mosquito coils, or by releasing liquid insecticidal components through heating, such as electric mosquito repellent liquids. However, both of these products require combustion or heating to disperse the insecticidal components, making them inconvenient for users to use anytime, anywhere. Another type of mosquito repellent is a self-volatile insecticidal agent. Its unique self-volatile system allows its insecticidal components to continuously evaporate and disperse into the air at room temperature without heating, achieving an insecticidal effect.

[0003] As consumers increasingly demand aesthetically pleasing and functional products, insect repellent products are gradually shifting towards an "appearance-driven economy." Some manufacturers have attempted to add dried natural plants or color-absorbing dried natural plants to room-temperature volatile insect repellent liquids to improve product appearance and enhance insect-repelling efficacy using the natural components of these plants. However, the results have been less than satisfactory, with most products exhibiting problems such as spoilage, deterioration, and fading. Traditional preservation and color-preservation technologies are primarily designed for natural plants stored in the air, using sealed packaging to slow oxidation. These technologies are unsuitable for the complex environment of room-temperature volatile insect repellent liquid formulations where natural plants are continuously immersed. Furthermore, conventional color-protecting agents may compromise the stability or diffusion efficiency of the insecticidal components in room-temperature volatile insect repellent liquid formulations, thereby rendering the self-volatile insect repellent liquid formulation ineffective. Therefore, there is an urgent need to develop a natural plant dehydration protection and color-preservation technology suitable for room-temperature volatile insect repellent liquid systems, simultaneously ensuring both insecticidal efficacy and the stability of the natural plant's color. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a self-volatile insecticidal liquid formulation containing natural plants. This self-volatile insecticidal liquid formulation can retain the pigments naturally present or artificially attached by the natural plants even when the natural plants are immersed in the complex environment of the insecticidal liquid formulation system for a long time, thus achieving color preservation and protection effects of the natural plants in the formulation. Moreover, the self-volatile insecticidal liquid formulation can be used normally without affecting its insecticidal efficacy.

[0005] This invention provides a self-volatile insecticidal liquid formulation containing natural plant materials, comprising the following raw materials in parts by weight:

[0006] The volatile solvent includes at least one of the following: dipropylene glycol monomethyl ether, tripropylene glycol butyl ether, tripropylene glycol methyl ether, 3-methoxy-3-methyl-1-butanol, and methyl acetoacetate.

[0007] In the process of researching the above-mentioned problems, the inventors discovered that known traditional color-protecting technologies are mainly aimed at protecting the color of natural plants in air or water systems. Most of these technologies rely on sealed packaging to delay oxidation. However, the systems of self-volatile insecticidal liquid formulations contain complex components, and the problems that natural plants face in these complex systems are significantly different from those they face in air or water systems. Therefore, traditional color-protecting technologies are not applicable. When natural plant materials are added to self-volatile insecticidal liquid formulations, these materials are constantly immersed in the formulation during storage and use. During this long-term storage, the natural plants may contain a certain amount of moisture due to their inherent properties or insufficient / uneven drying. Alternatively, moisture may be introduced into the formulation system during the production, storage, or use of the self-volatile insecticidal liquid formulation, leading to prolonged contact with moisture and resulting in spoilage and deterioration. Meanwhile, when natural plant materials are added to the self-volatile insecticidal liquid preparation, the color of the natural plant materials or color-absorbing natural plant materials changes during long-term storage. The main reasons for this change are as follows: (1) Since the natural plant materials are completely immersed in the room temperature volatile insecticidal liquid, the small molecule solvents in the room temperature volatile insecticidal liquid will penetrate into the interior of the flower material cells. The natural pigments (such as anthocyanins, betalains, chlorophyll, carotenoids) or color-absorbing pigments in the natural plants are easily leached out by the small molecules due to the presence of unsaturated bonds. This leads to a decrease in the color and deterioration of the appearance of natural plant materials; (2) Since the mosquito repellent liquid cannot be completely filled (if filled, the production process is prone to overflow), there is space left at the top, and a certain amount of air exists. At the same time, after the flower material is soaked in the mosquito repellent liquid, the air inside it and the small amount of air remaining on the surface of the flower material will not be completely discharged. The natural pigments (such as anthocyanins, betalains, chlorophyll, carotenoids) or color-absorbing pigments in natural plant materials contain unsaturated bonds, which slowly react with oxygen and are gradually oxidized, thus reducing the brightness. Moreover, conventional color-protecting agents may interfere with the stability or diffusion efficiency of insecticidal components (such as natural plant components and pyrethroids) in room temperature volatile insecticidal liquids, so they cannot be directly introduced into the self-volatile insecticidal liquid formulation system.

[0008] To address the aforementioned problems, the inventors propose using one or more of the following as volatile solvents in the system: dipropylene glycol monomethyl ether (DPM), tripropylene glycol butyl ether, tripropylene glycol methyl ether (TPM), 3-methoxy-3-methyl-1-butanol (MMB), and methyl acetoacetate (ACM). These components are low-boiling-point alcohols, ethers, or ester solvents, possessing good solubility and volatility, and are suitable for prolonged contact with the human body, exhibiting high safety and toxicity. Furthermore, the inventors screened these components through numerous experiments to obtain them as volatile solvents in the system, and found that these components have a protective effect on the long-term storage of natural plants: (1) Natural plant materials, due to their own inherent properties or insufficient or uneven drying, contain a certain amount of moisture. Long-term storage of natural plants carries the risk of spoilage, requiring the moisture to be extracted as much as possible. Such solvents have strong hydrophilicity; after soaking the natural plants, the water naturally present in the plants easily combines with the solvent, thereby extracting from the natural plants, reducing long-term contact between moisture and the natural plants, and minimizing damage to the natural plants. (2) If water is accidentally introduced during production or use, the solvent has a strong affinity for water, which will prevent water from being absorbed by natural plants and reduce damage to them. Furthermore, the inventors discovered during the experiment that the aforementioned components also have a protective effect on the pigments of natural plants. Analysis of these substances revealed that they have a certain molecular weight, making it difficult for them to directly penetrate into the interior of plant cell membranes. Since the main components of dried natural plant materials are high-molecular-weight cellulose, hemicellulose, and lignin, and due to the loss of moisture during the drying process, a hollow structure is formed between the internal cell walls and cell membranes. Cellulose, hemicellulose, and lignin contain oxygen atoms. The five substances (dipropylene glycol monomethyl ether (DPM), tripropylene glycol butyl ether, tripropylene glycol methyl ether (TPM), 3-methoxy-3-methyl-1-butanol (MMB), and methyl acetoacetate (ACM)) all contain multiple oxygen atoms and have a certain polarity. They have a strong affinity for cellulose, hemicellulose, and lignin in the cell walls, enhancing the surface wettability of cellulose, hemicellulose, and lignin in the cell walls. This facilitates the expulsion of air from the surface and interior of natural plants between the cell walls and cell membranes, reducing air stagnation inside and on the surface of natural plants, and enhancing the protection of natural plant pigments.

[0009] In one embodiment, the insecticidal ingredient includes at least one of the following: natural plant ingredients and their derivatives with insecticidal effects, volatile pyrethroid ingredients, volatile carbamate ingredients, DEET, IR3535, and hydroxymethylpyrrolidone.

[0010] In one embodiment, the natural plant ingredients and their derivatives with insecticidal effects include at least one of peppermint oil, menthyl alcohol, menthol, lemon essential oil, artemisia essential oil, wormwood essential oil, cinnamon essential oil, and camphor oil.

[0014] By capturing free radicals and inhibiting chain reactions, the oxidative deterioration of pigments is delayed. After good dissolution with the aforementioned solvents, this oxidant can form a protective ring around the natural plant, further reducing the oxidation of the natural plant and its pigments.

[0015] In one embodiment, the self-volatile insecticidal liquid formulation further includes 0.1-5 parts by weight of fragrance.

[0016] By adding fragrances, the aroma of the product is further enhanced, thus increasing its appeal.

[0017] In one embodiment, the self-volatile insecticidal liquid formulation further includes 0.001-0.1 parts by weight of an anti-ultraviolet agent.

[0018] Self-volatile liquid insecticides are mainly packaged in transparent containers, which expose them to light during shelf sale or use. Ultraviolet (UV) radiation can decompose natural pigments (such as anthocyanins and carotenoids) in natural plant materials, leading to fading. Therefore, depending on the product's shelf life and intended use, it may be necessary to introduce UV protectants to prevent the harmful effects of UV radiation on the components of natural plant materials.

[0019] In one embodiment, the UV stabilizer includes at least one of: benzophenone-3, benzophenone-4, benzophenone-5, 3-benzyl camphor, trimethylcyclohexyl salicylate, isoamyl p-methoxycinnamate, ethylhexyl salicylate, and diethylaminohydroxybenzoylhexyl benzoate.

[0020] The aforementioned UV protectant protects the natural plant material in the self-volatile insecticidal liquid formulation from the effects of light on the natural plant material.

[0023] The main types of materials are natural plant materials that are directly dried, dried after cell sap replacement, or dried after absorbing, impregnating, or spraying with pigments.
