Problems solved by technology

At present, industrial production mainly adopts reflux extraction method and continuous reflux extraction method, but these two extraction methods have some shortcomings and deficiencies in actual industrial production: ① The extraction efficiency is low, and the solvent needs to be renewed two to three times for each batch of extraction; ② The amount of solvent used is large, the operation process is cumbersome, time-consuming and labor-intensive; ③The total extraction time is long, the temperature is high, some active ingredients are lost or other chemical reactions occur, which significantly affects the product quality

Abstract

The invention discloses a compound natural plant extract with a spot-removing function and a preparation method and an application thereof. The compound natural plant extract is prepared by the following raw materials by mass: 50-100 parts of mulberry leaves, 30-60 parts of licorice, 10-50 parts of scutellaria, and 1-35 parts of bearberries. According to the invention, extraction is performed by ultrasonic wave extraction technology which shortens the extraction time, prevents damage of effective components caused by high-temperature heating; the obtained compound natural plant extract can effectively remove aged cutin, lightened spots from the inside to the outside of the body, provide sufficient moisture to maintain skin metabolism, accelerate the spot-removing process, has significant antioxidation effect during spot removal, can remove free radicals in the body, protect skin cells not to be influenced excessively by oxidized free radicals, alleviate skin aging, and eliminate the generation of face wrinkles. Through tests, the compound natural plant extract has no toxic or side effect, and is applicable to the preparation of high-efficient and safe spot-removing wrinkle-resistant cosmetics.

Description

technical field [0001] The invention relates to the field of plant Chinese herbal medicine and the technical field of daily cosmetics, in particular to a compound natural plant extract with the function of removing freckles and its preparation method and application. Background technique [0002] The appearance of pigmentation is due to the increase of skin pigmentation, which causes small spots such as black and yellowish brown on the skin. Sunburn, age spots and toxic melanosis etc. The color of human skin depends on the content and distribution of melanin. During the skin metabolic cycle, the tyrosine present in the melanocyte tissue undergoes dopa, dopaquinone, dopachrome, dihydroxyind Indole and other intermediates are gradually converted into melanin. When melanin grows too much and is unevenly distributed, it will cause localized skin to be too dark and pigmentation. In addition, when melanocytes receive a substance called "endothelin" that exists outside the cell...
