Ginseng moisturizing liquid capable of effectively reducing melanin and preparation method thereof

Abstract

The invention discloses ginseng moisturizing liquid capable of effectively reducing melanin and a preparation method thereof. The ginseng moisturizing liquid is prepared from ginseng extract, vitamins, glycerol, hyaluronic acid, ethylene glycol, ethyl laurate, citric acid, EDTA disodium, essence and water. The powder is stored in the form of freeze-dried powder, so that the stability of EGF can beprotected, and the stability of vitamin C can be protected; in a liquid state, citric acid and EDTA disodium can prevent vitamin C from being oxidized. EGF-TAT genes are transcribed into ginseng bodies, TAT can carry EGF to penetrate through cell membranes and directly reach the interiors of cells, the problem of skin permeability of macromolecular EGF is solved, the content of melanin and colored cells in skin cells can be effectively reduced, skin pigmentation is relieved, the skin pigmentation condition can be improved on the skin cell level, and the whitening effect is achieved. The EGF gene is transferred into the ginseng hairy roots by using a transgenic technology and is subjected to multiplication culture, so that a large number of ginseng hairy roots are obtained, EGF is obtainedat the same time, and the high cost for purchasing EGF is saved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a ginseng moisturizing liquid for effectively reducing melanin and a preparation method thereof. Background technique [0002] Ginseng has the reputation of "the king of herbs". It contains saponins, sugars, volatile oils, proteins, vitamins, amino acids, fatty acids, inorganic elements and other active ingredients, and has good whitening and skin rejuvenation effects. [0003] EGF is a kind of polypeptide growth factor that was discovered in the study of mouse nerve growth factor in the 1990s. Due to the physiological properties of EGF, at first, people used EGF as a medicine, and it was widely used in the treatment of skin burns, corneal transplantation, postoperative wounds, ulcers, bedsores, etc., and showed good therapeutic effects. EGF was therefore used as a Promising new drugs are used in the medical field. [0004] According to the good physiological properties of EG...

AI Technical Summary

Problems solved by technology

[0004] According to the good physiological properties of EGF, especially the activation of basal cells of the skin epidermis, biologists have boldly tried to apply it to cosmetics in recent years. This biological cosmetic is fundamentally different from traditional cosmetics. , in a sense, traditional cosmetics are more of a modifying effect, and cannot fundamentally solve skin problems; while the application of EGF in cosmetics is based on the physiological structure of human skin, which affects cells at the molecular level. To repair and adjust, improve or renew its composition and metabolism, etc. EGF has been used as a raw material for cosmetics for moisturizing, anti-wrinkle, whitening, skin rejuvenation and facial plastic surgery, which can promote the growth of skin cells and regulate the pigmentation in cells. Balance, recreate the optimal structure and state of the skin, rejuvenate skin cells

[0005] However, the cost of obtaining EGF is very high. The pure form of EGF on the market costs tens of thousands of dollars per gram, and the cost of obtaining ginseng is also higher than that of other plants.
