The invention discloses a multilayer mosquito repellent microcapsule and a preparation method and application thereof, the invention provides
camphor essential oil which is high in safety and effective, the
camphor essential oil and

Linalool can repel mosquitoes and prevent short-distance mosquitoes from
biting a
human body, and
linalool and
linalool have a synergistic effect. The invention further provides a multilayer mosquito repellent microcapsule, the microcapsule comprises an outer layer and an inner core, the outer layer wraps the inner core, the outer layer is a
glycerol layer containing linalool and
cinnamomum camphora essential oil, and an efficient space repellent layer is rapidly formed in the initial stage of use; the inner core is linalool and
cinnamomum camphora essential oil which are wrapped by beta-
cyclodextrin, and the linalool and the
cinnamomum camphora essential oil are slowly and durably released to form a long-acting space repelling layer. The invention solves the problems of slow effect taking of common microcapsules and short
effective time of mosquito-repellent volatile oil components, and provides a safe, low-
toxicity, quick-acting and long-term effective space repellent material and product with natural mosquito-repellent substances as components.
