Embodiment 1

[0025] The mosquito repellent liquid based on plant essential oil is composed of the following raw materials in parts by mass according to the optimal ratio: 0.5-28 parts of glucoside; 12-40 parts of ethanol; 0.12-20 parts of eucalyptus extract; 0.12-20 parts of citronella extract Liquid; 46-89 parts of distilled water.

[0026] The configuration method is as follows: put natural plant extracts and surfactants of appropriate quality into the same glass mortar, and mix them thoroughly in the mortar, then transfer the evenly mixed product to a glass beaker and add water to mix;

[0027] Place the glass beaker on an electromagnetic stirrer, stir at a stirring speed of 100-500 rpm, and add ethanol dropwise into the beaker after the bubbles in the mixed solution disappear. After it is mixed evenly, the solution that can be used to repel mosquitoes can be obtained after standing still. The product has a fragrant smell and has the effect of calming the nerves; it has been determined...

Abstract

The invention discloses a formula and a preparation method of a mosquito-repellent liquid capable of repelling mosquitoes, killing bacteria and purifying air. The mosquito-repellent liquid comprises the following raw materials in parts by weight: 0.5-28 parts of glucoside, 12 to 40 parts of ethanol, 0.12 to 20 parts of an eucalyptus extract, 0.12 to 20 parts of citronella extract and 46 to 89 parts of distilled water; or 0.5 to 28 parts of Tween 20-100, 12 to 40 parts of ethanol, 0.12 to 20 parts of the eucalyptus extract, 0.12 to 20 parts of Melaleuca alternifolia extract, 0.12 to 20 parts ofcitronella extract and 46-89 parts of distilled water. The mosquito-repellent liquid provided by the invention has remarkable mosquito repellent effect and is safe and pollution-free; a eucalyptus isrich in aromatic oil, has killing or repelling effect on various germs and pests, and can be made into insecticides, preservatives, mosquito-repellent oil and the like; and in addition, a certain bactericidal effect is achieved, and the breeding and spreading of pathogenic bacteria carried by mosquitoes can be reduced. The mosquito-repellent liquid is prepared from plant essential oil, does not contain artificially synthesized essence, preservatives and chemical pigments, smells pleasant and is beneficial to physical and psychological health. The components of the mosquito-repellent liquid are environmentally friendly and low in cost, and the mosquito-repellent liquid produces good social, ecological and economic benefits.

Description

technical field [0001] The invention relates to the field of deodorizing and repelling mosquitoes, in particular to a mosquito repelling liquid based on plant essential oils, which is applied to repelling mosquitoes and sterilizing bacteria, calming the nerves, purifying the air and the like. Background technique [0002] In tropical or subtropical regions, mosquitoes are rampant, not only sucking blood interferes with the normal life of human beings, but also spreads diseases. Mosquitoes are one of the main vectors, which can transmit infectious diseases such as malaria, yellow fever, and dengue fever, which seriously threaten human health. Mosquito repellants currently used in the market are mainly chemically synthesized DEET. Although it has a certain effect on repelling mosquitoes, with the long-term abuse of chemical insecticides, the resistance of mosquitoes has become more and more serious. It is getting stronger and stronger, and has certain side effects on the huma...
