Problems solved by technology

Although the present invention reduces the consumption of ethanol, the smell of peppermint oil is relatively strong, and long-term use has an impact on children's sense of smell. In addition, the preparation process is cumbersome and the effective time for repelling mosquitoes is short, so it is urgent to develop a new Mosquito repellent toilet water with natural ingredients

Abstract

The invention discloses mosquito-repellent floral water and a preparation method thereof. The mosquito-repellent floral water comprises the following raw materials in percentage by weight: 15-25 percent of lemongrass extracting solution, 7-9 percent of glycerin, 0.5-0.7 percent of sodium chloride, 10-15 percent of ethanol and the balance of water. The preparation method comprises the following steps: step 1, weighing raw materials; step 2, adding water, ethanol and sodium chloride into the reaction kettle, and stirring, thereby obtaining a mixture A; step 3, adding glycerin into the mixture A, and stirring, thereby obtaining a mixture B; and step 4, adding the lemongrass extract into the mixture B, stirring, standing, and defoaming, thereby obtaining the mosquito-repellent floral water. The mosquito-repellent floral water is prepared by taking the lemongrass extracting solution as a raw material, and the raw materials are green and natural and do not have any irritating effect to a human body. Because the lemongrass has the fragrance of lemon, the addition amount of essence is reduced, and the floral water is particularly suitable for children. In addition, the floral water prepared by the lemongrass is long in drug effect, and mosquito bites can be effectively avoided.

Description

technical field [0001] The invention relates to the field of toilet water, in particular to a mosquito repelling toilet water and a preparation method thereof. Background technique [0002] Summer is the best time for various insects to breed, especially blood-sucking animals such as mosquitoes, which have a particularly strong reproductive ability. Children's skin is very delicate. Once bitten by mosquitoes, symptoms such as redness, swelling, and itching will appear immediately. Mosquitoes are also carriers of various pathogenic bacteria, which may cause more harmful infectious diseases. Therefore, children's toilet water is more and more favored by mothers.
