This invention relates to the field of cosmetic products, specifically disclosing a long-lasting mosquito-repellent lacquerwood wax composite balm. This composite balm, by weight fraction, comprises 20-25 parts by weight of lacquerwood peel wax, 12-18 parts by weight of lemon eucalyptus oil, 3-8 parts by weight of catnip oil, 35-45 parts by weight of a temperature-controlled phase change regulating oil, 5-10 parts by weight of a hydrophobic plant-derived film-forming agent, 2-5 parts by weight of isosorbide dicaprylate, and 0.5-1 part by weight of a fat-soluble antioxidant. The long-lasting mosquito-repellent lacquerwood wax composite balm of this invention achieves a long-lasting and stable release of mosquito-repellent active ingredients, while also possessing suitable temperature-controlled phase change properties, a pleasant skin feel, synergistic mosquito-repellent effects, excellent hydrophobic and sweat-resistant capabilities, and stable storage of natural components.

According to the efficient mosquito repellent liquid and the preparation method thereof, trans-menthanediol serves as a main active component, cis-menthanediol can serve as a secondary active component, the total content of trans-menthanediol and cis-menthanediol is 6%-20%, and the effective repelling time of the mosquito repellent liquid is remarkably prolonged; in addition, by increasing the proportion of the trans-menthanediol with the configuration, the effective mosquito-repelling time of the mosquito-repelling liquid is remarkably prolonged under the same concentration; on the basis, a small amount of eucalyptus citriodora essential oil is added to serve as a synergistic component, synergistic interaction can be further achieved, the continuous mosquito repelling performance is improved, and the whole formula is free of toxic and side effects and high in safety.
