Abstract

The invention belongs to the field of mosquito repellent, particularly relates to a natural plant essential oil microcapsule as well as a preparation method and application thereof. The natural plant essential oil microcapsule comprises a capsule core and a capsule wall, and the capsule core is a plant essential oil compound. The plant essential oil compound comprises citronella essential oil, lemon essential oil, folium eucalypti essential oil, peppermint essential oil, camphor essential oil and herba schizonepetae essential oil. The preparation method successively comprises: preparation of the capsule core, preparation of the capsule wall, microencapsulation and post-treatment. The application is the application in the mosquito repellent. The technical scheme of the invention realizes microencapsulation of the compounded plant essential oil and slow release of the essential oil, prolongs the using time without affecting mosquito repelling effects, and realizes the substantial increase of utilization rate of the plant essential oil. Under normal use, the natural plant essential oil microcapsule can sustainably release for 3 to 6 months and effectively repel mosquitoes within 3 meters. The natural plant essential oil microcapsule smells fragrant and has refreshing functions.

Description

technical field [0001] The invention belongs to the field of mosquito repellents, and in particular relates to a natural plant essential oil microcapsule, a preparation method and an application. Background technique [0002] With the continuous increase of the global greenhouse effect and the deterioration of the environment, the World Health Organization (WHO) believes that mosquitoes will have a further impact on human health, especially the health of young children. Mosquitoes are one of the important ways to spread many diseases, such as malaria, B Encephalitis, dengue fever, yellow fever, filariasis and other diseases are all caused by mosquito bites. More than half of the world's population lives at risk of mosquito-borne diseases. In daily life, repellants are commonly used to prevent mosquito bites. Repellent refers to a certain special odor that can be volatilized naturally, so that insects will repel them after smelling them and dare not approach them. Insect r...
