Abstract

The invention discloses a preparation method of a bacteriostatic itching-relieving natural compound botanical mosquito repellent liquid. The preparation method is characterized in that beewax is taken as a corrosion inhibitor, menthol and thymol are taken as bacteriostatic agents and plant essential oil is taken as a mosquito repellent. The preparation method includes adding, by volume, 22-26% of geranium oil, 22-26% of cinnamon oil, 18-23% of eucalyptus oil, 15-20% of peppermint oil, 6-10% of Herba Artemisiae Annuae oil and 6-10% of Litsea cubeba oil into a reactor sequentially, and adding an ethanol solution with the beewax and an ethanol solution with the menthol and the thymol sequentially so as to obtain yellowish transparent liquid, namely the bacteriostatic itching-relieving natural compound botanical mosquito repellent liquid. The bacteriostatic itching-relieving natural compound botanical mosquito repellent liquid full of natural faint scent has the bacteriostatic and slow release effects, is free of side effect to a human body, convenient to use and capable of making the mosquito repellent effect last for 10-12 hours, and achieves mosquito repellent effect above 90% on average.

Description

technical field [0001] The invention relates to a mosquito repellent preparation, in particular to a preparation method of a bacteriostatic and antipruritic natural compound plant mosquito repellent liquid and its application in cosmetics, belonging to the technical field of cosmetics. Background technique [0002] The main components of plant essential oils are monoterpenes, sesquiterpenes, aliphatic compounds and aromatic hydrocarbon derivatives, which have many biological activities. At present, plant essential oils have formed a new field in terms of antibacterial, antioxidative, and insecticidal. Especially for the control of sanitary pests, natural pyrethrins, plant essential oils and other plant-derived insecticidal active substances have the advantages of being safe for humans and animals, delaying pest resistance, and not polluting the living environment, and have great development potential and application in the field of sanitary insecticide value. Studies have ...
