Water-based electrothermal mosquito incense liquor using cardonol derivative as solvent

Abstract

The invention relates to a sanitary pest killing product, and provides a water-based electrothermal mosquito incense liquor using cardonol derivative as a solvent. The water-based electrothermal mosquito incense liquor has the advantages that the dissolving of effective ingredients is easy, the volatizing is stable, the drug efficiency is long, the complete biodegrading is realized, the pollution to the environment is avoided, and the cost is low. The water-based electrothermal mosquito incense liquor comprises the following components in percentage by weight: 0.2% to 2% of natural pyrethrum, 8% to 35% of cardonol derivative, 5% to 15% of polyhydric alcohol, 0% to 0.2% of anti-oxidant, and balance of deionized water.

Description

technical field [0001] The invention relates to the field of hygienic insecticide, in particular to a water-based electric heating mosquito-repellent incense liquid using a cardanol derivative as a solvent. Background technique [0002] Currently commercially available electric mosquito-repellent incense liquids generally use kerosene and other oily ingredients as solvents, alkane solvents as carriers, pyrethroids, antioxidants, and flavors as components, and form a homogeneous system by mixing and stirring the solvents. When in use, the alkane solvent volatilizes into the air, so that the active ingredient diffuses with the volatilization of the alkane solvent, thereby contacting the target to produce a drug effect. We usually call this kind of product oil-based electric heating mosquito-repellent liquid, and this oil-based electric heating mosquito-repellent liquid has the following disadvantages: [0003] 1. The environment is highly polluted and not environmentally frie...

AI Technical Summary

Problems solved by technology

[0003] 1. The environment is highly polluted and not environmentally friendly. Carbon-containing substances appear when the oil matrix volatilizes or decomposes, which is harmful to the environment and does not conform to the current environmental protection concept of low-carbon economy, energy saving and emission reduction;

[0004] 2. The cost is high and cannot be biodegraded. In order to make a profit, the manufacturer must increase the selling price of the product and pass it on to the consumer, which is not good for the consumer;

[0005] 3. The waste of energy is large, using kerosene and other oily ingredients as solvents, kerosene comes from petroleum, and as a non-renewable resource, petroleum is very precious to human beings and worth cherishing and utilizing

[0006] 4. Alkane solvents can burn when exposed to open flames, and are flammable liquids, which bring certain fire risks to transportation, storage and household use

[0007] For solving oil-based electric mosquito-repellent incense liquid environmental pollution is big, cost is high, the problem of energy waste is big, Chinese Patent No. is: CN Lee CN102077836A discloses the mosquito-repellent water-based liquid preparation of electric heating, and its component (percentage by weight) comprises: four Flumethrin 0.31-0.62%, propylene glycol 15.00-20.00%, sulfolane 10.00-15.00%, hydrogenated castor oil 0.30-0.90%, deionized water 63.48-74.39%, although the water-based electric heating mosquito-repellent liquid can save costs, Reduce environmental pollution. However, during the research and preparation process of this type of water-based liquid mosquito-repellent incense, we found that it has defects such as difficult to dissolve active ingredients, unstable volatilization of active ingredients, and drug efficacy that cannot meet market requirements. Sulfur-containing sulfolane solvent is used, which is relatively corrosive, and it will decompose sulfur dioxide at high temperature, which has hidden dangers in use
