Problems solved by technology

However, the direct addition of pearl powder and Chinese medicine extract in cosmetics is greatly restricted, because the calcium carbonate and trace elements contained in pearl powder will destroy the emulsification system of cosmetics and reduce the stability of the product; while the color of Chinese medicine extract is darker, Adding directly to cosmetics will not only affect the appearance of the paste, but also reduce the quality of the product and shorten the shelf life of the product
The above reasons limit the addition and use of pearl powder and traditional Chinese medicine in cosmetics, affecting the combined development of cosmetics, pearls and traditional Chinese medicine, making it difficult to make breakthroughs in the beauty and nutritional properties of cosmetics, and hindering the development of the cosmetics industry.

Abstract

The invention relates to a cosmetic, in particular to a silicon dioxide-coated compound skin-whitening pearl powder. PEG-1000, compound pearl powder, sodium silicate solution and sulfuric acid solution are pulped, ground, coated, washed by water, dried and milled by jet, so that the silicon dioxide-coated compound skin-whitening pearl powder is prepared; traditional Chinese medicine extract is sprayed on nano pearl powder with a grain diameter less than 200 nanometers, and after drying and milling, the compound pearl powder is produced; and the traditional Chinese medicine extract is the mixture of Chinese angelica extract, gingkgo extract, white grape extract and mulberry root extract. The technique is simple, the coating effect of the silicon dioxide-coated compound skin-whitening pearl powder is good, the coating is complete, floc does not exist among grains, the silicon dioxide-coated compound skin-whitening pearl powder can be widely applied to emulsion and cream in cosmetics, and can help to promote the development of the combination of cosmetics, pearl and traditional Chinese medicines, and the application range of pearl powder in cosmetics can be greatly broadened.

Description

technical field [0001] The invention belongs to the field of cosmetics, in particular to a compound whitening pearl powder coated with silicon dioxide. Background technique [0002] Pearls have always been recognized as a beauty product. The trace elements and various amino acids contained in them provide skin whitening and nutrition protection. Traditional Chinese medicine beauty has also inherited Chinese culture for thousands of years. There are many examples of ancient Chinese medicine beauty. For example, "Qibai San" is to use traditional Chinese medicine to remove freckles and whiten skin. [0003] In today's society, using traditional Chinese medicine for beauty treatment has become a fashion. However, the direct addition of pearl powder and Chinese medicine extract in cosmetics is greatly restricted, because the calcium carbonate and trace elements contained in pearl powder will destroy the emulsification system of cosmetics and reduce the stability of the product; ...
