Embodiment 1

[0028] A kind of preparation method of water-soluble silk fibroin and sericin composite beauty product, described preparation method comprises the steps:

[0029] (1) Using spring cocoon and fresh cocoon as raw material, remove the polluted cocoon, peel off the cocoon coat, remove the silkworm chrysalis and molted skin, use a cotton opener to loosen the cocoon shell and make silk fibers;

[0030] (2) Boil the deionized water, put into the silk fiber obtained in step (1), the weight of the silk fiber in 1L of deionized water is 10g; boil for 10 minutes, take out the silk fiber, and obtain the sericin solution; The sericin solution was concentrated by rotary evaporation before cooling to obtain a concentrated sericin solution with a concentration of 5%, and then placed in refrigeration at 4°C. The concentration temperature of the rotary evaporation was 50°C and the rotation speed was 60 rpm; The silk fibroin is washed with clear water and dried for later use;

[0031] (3) Refri...

Abstract

The invention relates to a preparation method of a water-soluble silk fibroin and sericin composite cosmetic product. To degrade sericin into sericin peptide, alkaline hydrolysis or enzymatic hydrolysis is generally used. These methods are difficult to separate the additives after degradation, and the existence of additives will affect the safety of sericin peptide used in skin care products. The present invention uses a physical method to degrade sericin. The sericin solution with good water solubility in sericin is easy to form a gel. At a low concentration of about 5%, the sericin macromolecules stretch out and form in the gel. The network shape, the special shape of sericin gel, makes it possible to use physical methods to achieve the effect of degrading sericin by cutting and vibrating the gel. The present invention adopts the method of combining repeated cutting and shaking to obtain sericin peptide with an average molecular weight of about 3000. This sericin peptide is mixed with silk fibroin to prepare a mixed sheet mask with good water solubility and play a role in moisturizing the role of the skin.

Description

technical field [0001] The invention relates to a preparation method of a water-soluble silk fibroin and sericin composite cosmetic product. Background technique [0002] The silk fibroin extracted from silk has good film-forming properties and can be made into a silk sheet mask. The silk fibroin sheet mask can be dissolved in water or beauty essence and then applied directly on the face to form a mask. After a certain period of skin care, it is washed off with water. The advantages of silk fibroin sheet mask are: moisturizing, repairing, and cleaning cosmetic effects, such as the Chinese patent application number 201611044392.7; because it contains very little water, it does not need to add preservatives and other chemical substances, which is more beneficial to skin maintenance; There is no need for mask backing paper, which is good for the environment. Another protein extracted from silk is sericin, which has no film-forming properties. However, sericin contains more h...
