Abstract

The invention relates to a mosquito dispelling and skin toning product for infants, and provides a mosquito dispelling toner for the infants. The mosquito dispelling toner is characterized in that the mosquito dispelling toner comprises 15-20wt% of a stonewort extract, 1-5wt% of glycerin, 1-5wt% of an emollient, 2-7wt% of sodium hyaluronate, a proper amount of a perfume, and the balance purified water, wherein the stonewort extract is a water-soluble part obtained after removing chlorophyll and polysaccharides from a stonewort ethanol extract. The mosquito dispelling toner provided in the invention has the advantages of no harmful components, simple production technology and low cost.

Description

technical field [0001] The invention relates to a mosquito-repelling skin care product for babies, in particular to a mosquito-repelling toner for infants with mosquito-repelling effect made by using water-soluble matter in the extract of the lower algae plant Charophyllum as the main active ingredient. Background technique [0002] The main substances contained in the baby oil mosquito repellent products currently on the market are pyrethrin compounds and their derivatives, but reports have shown that pyrethrin compounds can cause poisonous effects on fish and have certain biological safety , so its mosquito repellent products may have some negative effects on infants and young children. [0003] Charophyta is a low-level aquatic plant, widely distributed, easy to cultivate, short growth cycle, large yield, and the water-soluble part of its extract not only contains nutrients, but also has a good effect on Culex light-colored and Aedes albopictus. Repelling effect. At pre...
