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.

This invention discloses an antibacterial and mosquito-repellent composite material based on plant extracts, its preparation method, and a latex paint. The method includes: providing a zinc ion solution and an alkaline precipitant solution, wherein the alkaline precipitant solution is selected from at least one of sodium hydroxide solution, potassium hydroxide solution, or ammonia water; mixing and reacting the zinc ion solution and the alkaline precipitant solution, controlling the final pH value of the reaction to be 8-11, and then post-processing to obtain nano-zinc oxide particles; dispersing the nano-zinc oxide particles in an L-cysteine ​​solution, adding a stabilizer to obtain an L-cysteine-modified nano-zinc oxide dispersion; adding β-alanine and plant extracts to the nano-zinc oxide dispersion, homogenizing and drying to obtain the antibacterial and mosquito-repellent composite material; wherein the plant extract is selected from at least one of thymol or geraniol, nocaketone, physalisol, citronella oil, and lemon eucalyptus oil, combined with thymol. This invention can produce an antibacterial and mosquito-repellent composite material with long-lasting antibacterial and mosquito-repellent effects.
