Abstract

The invention discloses sunscreen lotion containing natural plant sunscreen components and a preparation method thereof, which comprises A component, B component and de-ionized water; wherein, the A component comprises 5 percent to 10 percent of whiteruss, 3 percent to 8 percent of octodecyl alcohol, 3.5 percent to 6 percent of stearic acid, 0.6 percent to 1.2 percent of sodium lauryl sulfate and 0.1 percent to 0.2 percent of nipagin methyl ester; the B component comprises 6 percent to 9 percent of glycerin, 1 percent to 3 percent of Chinese traditional medicine ingredients, 0.3 percent to 0.5 percent of essence and 0.1 percent to 0.2 percent of nipagine propyl ester; the Chinese traditional medicine ingredients per gram is composed of 0.15 gram to 0.30 gram of flos sophora, 0.50 gram to 0.75 gram of honeysuckle and 0.10 gram to 0.20 gram of peony. When the sunscreen cream is prepared, the Chinese traditional medicine is firstly prepared. Secondly, the A and the B components are respectively heated to about 80 DEG C to be melted, the A component is added into the B component along with stirring, and then the de-ionized water is added into the mixture. The fast stirring can not stop until the mixture is emulsified completely, and then the mixture is cooled to obtain the sunscreen lotion containing natural plant sunscreen components. The invention has broad-spectrum function to UV-A and UV-B rays and compensates the deficiency of a single component, and has favorable effect on absorbing ultraviolet radiation.

Description

technical field [0001] The invention relates to a sunscreen and a preparation method thereof, in particular to a sunscreen containing natural plant sunscreen ingredients and a preparation method thereof. Background technique [0002] Ultraviolet light is one of the sections of solar radiation, with a wavelength of about 230nm to 400nm. According to the wavelength, it is divided into UV-A (315nm to 400nm), UV-B (280nm to 315nm), and UV-C (230nm to 280nm). Only a very low dose of UV-A and a very small dose of UV-B can reach the earth, while UV-C cannot reach the surface of the earth, and UV-B is the most harmful to living things. [0003] Huai Mi contains a large amount of protein, rutin (rutin), and 19 kinds of amino acids (including 8 kinds of essential amino acids in Huai Mi). Rutin is a flavonoid compound extracted from Sophora japonica, which has good ultraviolet absorption in the UV-A segment; it has a significant antioxidant effect, can inhibit the generation of lipid ...
