Abstract

The invention discloses a long-acting waterproof mosquito repellent emulsion. The raw material composition is calculated as 100% by weight, including 5%~35% DEET, 1%~5% emulsifier, 0.3%~2% retardant release material, 0.5%~5% waterproof material, 0.1%~0.5% preservative, and the balance is water. The long-acting waterproof mosquito repellent emulsion of the present invention has a good effect of preventing mosquitoes and insects from biting, and has both long-acting and waterproof functions, which can solve the problems of existing mosquito repellent products such as short repellent time, inconvenient use, high safety hazards and no waterproof function. Insufficient, suitable for long-term mosquito repellent and waterproof needs in special environments; and the mosquito repellent product is an emulsion, which has the characteristics of easy application, good comfort, and moisturizing; its preparation process is simple, equipment requirements are low, and the cost is low. Suitable for industrialized mass production.

Description

technical field [0001] The invention belongs to the field of daily chemical products, and in particular relates to a long-acting waterproof mosquito repellent emulsion and a preparation method thereof. Background technique [0002] High temperature and high humidity in summer are the most serious seasons for mosquitoes and other blood-sucking insects. In addition to causing itching, pain, inflammation and other uncomfortable symptoms, mosquito bites are also the transmission route of various insect-borne diseases such as malaria, Ebola fever and dengue fever. Due to the needs of special missions such as military training, field training, flood fighting and disaster relief, and peacekeeping, army officers and soldiers are exposed to harsh environments and are at greater risk of being bitten by mosquitoes. Mosquito bites not only directly threaten the health of officers and soldiers, cause non-combat injuries or attrition, but also affect the combat effectiveness and task exe...
