Abstract

The invention discloses sunblocking cream containing natural sunblocking ingredients and a preparation method thereof. The sunblocking cream comprises a component A, a component B and deionized water, wherein the component A consists of 8 to 12 percent of caprylic acid/caprin, 2 to 4 percent of stearic acid, 3 to 6 percent of hexadeca octadecanol, 2.5 to 6 percent of isopropyl palmitate, 1 to 1.6 percent of gyceryl monostearate, and 0.1 percent of propylparaben; the component B consists of 5 to 10 percent of natural plant ingredients, 5 to 8 percent of glycerol, 2 to 2.4 percent of cetanol ether phosphate sylvite, and 0.1 percent of methyl hydroxybenzoate; the balance being the deionized water; and 1 gram of the natural plant ingredients consist of 0.40 to 0.60 gram of grape leaf, 0.25 to 0.50 gram of sweet osmanthus and 0.10 to 0.15 gram of green tea. During the preparation, the natural plant ingredients are prepared firstly. The component A and the component B are respectively heated up to about 80 DEG C so as to be dissolved, and are stirred and mixed evenly; the deionized water is added into the component A and the component B; and the solution is stirred rapidly for complete emulsification and then is cooled down to obtain the sunblocking cream. The sunblocking cream has the advantages that the sunblocking cream has stronger absorption property for medium-wave and long-wave ultraviolet rays, and can effectively prevent the radiation of the ultraviolet rays on skin without generating any adverse reactions such as stimulus and irritability and so on.

Description

technical field [0001] The invention relates to a sunscreen and a preparation method thereof, in particular to a sunscreen containing natural sunscreen ingredients extracted and formulated from grape leaves, sweet-scented osmanthus and green tea and a preparation method thereof. Background technique [0002] Ultraviolet rays can be divided into short-wave (190-280nm), medium-wave (280-320nm) and long-wave (320-400nm). Short-wave ultraviolet light has the shortest wavelength and the strongest energy, but it can be absorbed by the ozone layer 25 kilometers above the ground and cannot reach the ground, so it will not cause sunburn to the skin. The ultraviolet bands that cause sunburn to the skin mainly include medium wave and long wave. Among them, the transmission ability of medium-wave ultraviolet rays can reach the ground, which is the main band that causes skin sunburn and is also the key band for sun protection. It is generally called "ultraviolet rays in the B area (UVB)...
