Abstract

The invention discloses a broad-spectrum chemical sun-screening agent, broad-spectrum sunscreen cream and a preparation method thereof. The broad-spectrum sun-screening agent disclosed by the invention is prepared from 3-methoxycinnamic acid (2-ethyl) hexyl ester and 3,5-dimethoxy-4 hydroxycinnamic acid (2-ethyl) hexyl ester, wherein a mass ratio of the 3-methoxycinnamic acid (2-ethyl) hexyl esterto the 3,5-dimethoxy-4 hydroxycinnamic acid (2-ethyl) hexyl ester is (0.5 to 5) to (5 to 0.5). The broad-spectrum chemical sun-screening agent can intensely absorb light in an ultraviolet UVB area and a UVA area, and a ratio of light absorbance for absorbing light in the ultraviolet UVB area and the UVA area is (0.5 to 5) to (5 to 0.5). The prepared broad-spectrum sun-screening agent disclosed bythe invention is prepared from 3-methoxycinnamic acid (2-ethyl) hexyl ester, 3,5-dimethoxy-4 hydroxycinnamic acid (2-ethyl) hexyl ester, a calendula officinalis extracting solution, tea polyphenol, tween 80, zinc oxide, Vaseline, glycerinum and distilled water. The sun-screening agent disclosed by the invention can be applied to the effective quantity of cosmetically-acceptable carriers to prepare and obtain sunscreen cream. The sunscreen cream has the characteristics of broad-spectrum sunscreen, no irritation to the skin, no toxic and side effect and higher user safety.

Description

technical field [0001] The invention relates to a daily chemical skin care product and a preparation method thereof, in particular to a sunscreen, a sunscreen containing the sunscreen and a preparation method thereof. Background technique [0002] For humans, if the skin is exposed to the hot sun for a long time, due to the direct contact of strong ultraviolet light with the skin, it will cause redness or tanning, which will cause skin damage, spots, sagging skin or wrinkles. In severe cases It can cause cancer such as melanoma, so effective sun protection is very necessary. Although there are many kinds of sunscreens on the market, they have shortcomings such as short duration, narrow range of effective sun protection, and unknown adverse effects caused by long-term use of artificial molecules. Contents of the invention [0003] Aiming at the prior art, the present invention fully makes up for the shortcomings of existing similar products, and provides a broad-spectrum s...
