Description

Nonalcoholic spray for repelling mosquitoes and relieving itching and preparation method thereof

Technical Field

The invention belongs to the technical field of daily chemical industry, and particularly relates to nonalcoholic mosquito-repelling itching-relieving spray and a preparation method thereof.

Background

In summer, in order to avoid mosquito bites, mosquito repellent toilet water is often applied to the body. Various toilet waters are available in the market at present, but the traditional raw materials of the toilet water are mosquito repellent ester, alcohol, menthol, borneol, thymol, camphor, essence, alcohol and deionized water, and the toilet water has the functions of cooling and removing miliaria and has little effect on insect dermatitis caused by mosquito bites. The effective component of most toilet water is mosquito repellent ester, for example, Chinese patent 03116972.4, mosquito repellent toilet water, and the raw material contains mosquito repellent ester, which is the main active component for repelling mosquito. The anophelifuge ester has certain toxicity, and can be absorbed by digestive tract and respiratory tract during application to induce asthma, and cause cancer and teratogenesis. Ethanol is added into a plurality of toilet water, such as Chinese patents 200910192803.0, 201020112216.9 and the like, when the mosquito repellent is used, the aim of repelling mosquitoes is achieved by means of volatilization of the ethanol, but the acting time is short, and many people are sensitive to the ethanol, especially children, old people and people allergic to the ethanol, so the application range of the mosquito repellent is greatly reduced.

At present, the functions of the toilet water are mainly divided into mosquito repelling and itching relieving, most of the commercially available toilet water has single function, and the effective time is short. How to organically combine the two to prepare the mosquito-repelling itching-relieving toilet water which is non-toxic and non-irritating to human bodies is a problem which needs to be solved urgently in the field of daily chemicals at present.
