Silk fibroin composite hydrogel applicable to sensitive skins and method for preparing silk fibroin composite hydrogel

Abstract

The invention discloses silk fibroin composite hydrogel applicable to sensitive skins and a method for preparing the silk fibroin composite hydrogel. The silk fibroin composite hydrogel comprises, by weight, 23-36 parts of silk proteins, 8-19 parts of tussah silk proteins, 9-17 parts of collagen, 9-21 parts of sericin, 13-25 parts of hyaluronic acid, 3-16 parts of trehalose, 6-14 parts of loofah extract, 2-11 parts of avocado extract, 7-18 parts of urea, 3-12 parts of vitamin E, 4-12 parts of vitamin C and 20-38 parts of deionized water. The silk fibroin composite hydrogel and the method have the advantages that the silk fibroin composite hydrogel is high in absorption speed, and good moisturizing effects can be realized; the silk fibroin composite hydrogel has functions of isolating harmful substances, absorbing ultraviolet rays and the like, and accordingly double skincare and protection effects can be realized; the silk fibroin composite hydrogel is mild in property, free of irritant components and applicable to the sensitive skins.

Description

technical field [0001] The invention belongs to the field of cosmetics and relates to a cosmetic using silk as a raw material, in particular to a silk fibroin composite hydrogel suitable for sensitive muscles and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, cosmetics have almost become an indispensable daily necessities for people, and the requirements for cosmetics are increasingly natural, nutritious, non-irritating and so on. Based on this, the research on the use of silk protein has also received more and more attention. [0003] Used in cosmetics, silk protein is one of the best raw materials in cosmetics at present. It has no toxic and side effects, has good affinity with the human body, has no irritation to the skin, no allergic reaction, and has strong penetration. Some data show that: silk protein can be absorbed by human cells in about 10 seconds; it can also absorb ultraviolet rays and has the effe...
