Abstract

The invention relates to a slow-release long-acting skin-whitening sunblock and a preparation method thereof, and belongs to the technical field of preparation of cosmetics. The slow-release long-acting skin-whitening sunblock is prepared by mixing a prefabricated material, a hyaluronic acid water solution and a chitosan acetic acid solution for reaction, wherein the prefabricated material is prepared from the following raw materials in parts by weight: composite nano-oxide microspheres, acid-etched porous pearl powder, a silk protein solution, dimethicone; caprylic decyl triglyceride, vitaminE, aloe powder and deionized water; the composite nano-oxide microspheres are prepared from titanium tetrachloride, deionized water, hydrogen peroxide, sodium silicate, sodium dodecylbenzene sulfonate, hydrochloric acid and hexadecyl trimethoxysilane through reaction; and the acid-etched porous pearl powder is prepared from pearl, castor oil, absolute ethyl alcohol and deionized water through reaction. The effective sun-blocking time of the slow-release long-acting skin-whitening sunblock is effectively prolonged, the skin-whitening effect is enhanced, and the slow-release long-acting skin-whitening sunblock is low in irritation property and strong in broad-spectrum property and has a wide application prospect.

Description

technical field [0001] The invention relates to a slow-release long-acting whitening sunscreen and a preparation method thereof, belonging to the technical field of cosmetic preparation. Background technique [0002] With the improvement of living standards, people's requirements for the quality of life are getting higher and higher. Irritant or non-irritating, etc. [0003] Ultraviolet rays are invisible rays located in the high-energy area of ​​sunlight, which cannot be seen by human eyes. Excessive ultraviolet radiation is causing more and more harm to human health. Protecting against ultraviolet rays is an extremely urgent problem. Therefore, in terms of female beauty, sun protection is very important. The development of safe and effective sunscreen products is a promising branch of contemporary fine chemicals. [0004] However, the current common sunscreens are mostly made of chemically synthesized raw materials, which are easy to irritate the skin, and the active in...
