Embodiment 1

[0028] Example 1: Silk Fibroin Gel Mask Cream

[0029] The silkworm cocoon is obtained by peeling the cocoon and removing the pupae to obtain the cocoon layer. With 5g / L Na 2 CO 3 Scouring the cocoon layer with an aqueous solution twice, 30 minutes each time, at a scouring temperature of 98°C, and a bath ratio of 1:100. After scouring, it is fully washed with distilled water and dried naturally to obtain silk fiber. With 1000g / L CaCl 2 The aqueous solution dissolves the silk fiber, the dissolution temperature is 98°C, the bath ratio is 1:25, and the time is 10 minutes. The solution obtained after dissolution was poured into a cellulose dialysis membrane (molecular component 12,000-14,000), and dialyzed in running water for 3 days. The dialyzed solution was air-dried and concentrated to obtain an aqueous silk fibroin solution. Add 5 g / L water-soluble sericin to the 50 g / L silk fibroin aqueous solution, and let it stand at 60°C until the solution becomes a translucent gel,...

Embodiment 2

[0031] Embodiment two |, silk fibroin gel anti-aging facial mask cream

[0032] The silkworm cocoon is obtained by peeling the cocoon and removing the pupae to obtain the cocoon layer. With 5g / L Na 2 CO 3 Scouring the cocoon layer with an aqueous solution twice, 30 minutes each time, at a scouring temperature of 98°C, and a bath ratio of 1:100. After scouring, it is fully washed with distilled water and dried naturally to obtain silk fiber. Dissolve the silk fiber with calcium chloride, water and ethanol solution with a molar ratio of 1:8:2, the dissolution temperature is 70°C, the bath ratio is 1:25, and the time is 10 minutes. The solution obtained after dissolution was poured into a cellulose dialysis membrane (molecular component 12,000-14,000), and dialyzed in running water for 3 days. The dialyzed solution was air-dried and concentrated to obtain an aqueous silk fibroin solution. Add 10g / L water-soluble sericin to 60g / L silk fibroin aqueous solution, add 10g / L silk ...

Embodiment 3

[0043]Example 3: silk fibroin gel nourishing face cream

[0044] The silkworm cocoon is obtained by peeling the cocoon and removing the pupae to obtain the cocoon layer. Scouring the cocoon layer 2 times with 0.4% neutral soap solution, 1 hour each time, scouring temperature 98°C, bath ratio 1:100. After scouring, it is fully washed with distilled water and dried naturally to obtain silk fiber. A ternary solvent mixed with lithium bromide, ethanol and water at a weight ratio of 45:53:2 is used to heat and dissolve silk fibers at a temperature of 70-100°C. Bath ratio 1:50. The solution obtained after dissolution was poured into a cellulose dialysis membrane (molecular component 12,000-14,000), and dialyzed in running water for 3 days. The dialyzed solution was air-dried and concentrated to obtain an aqueous silk fibroin solution. Add 30 g / L propylene glycol to the 80 g / L silk fibroin aqueous solution, and let it stand at 50° C. until the solution becomes a translucent gel. ...

Abstract

The present invention discloses preparation process of skin care silk protein gel cream. The preparation process includes the following steps: adding water soluble sericin or water soluble sericin and silk peptide as gel promoter into water solution of fimbrin through homogeneous mixing; stilling the solution at 0-90deg.c for gelatinizing the solution into translucent silk protein gel with water content of 70-98 %; and homogenizing and emulsifying to form silk protein gel cream. Into the silk protein gel cream, other cosmetics matrix component and supplementary material component may be added as required. The silk protein gel cream has the functions as nutrient additive, humectant and matrix, and may be used in producing high quality natural skin care cosmetics.

Description

technical field [0001] The invention relates to a preparation method of a silk fibroin gel cream used for beauty, skin care and skin repair. Background technique [0002] With the improvement of living standards, people pay more and more attention to beauty and skin care, and the quality requirements of beauty and skin care products are also getting higher and higher. Cosmetic and skin care products containing natural active ingredients extracted from organisms such as collagen, silk fibroin, seaweed extract, and ginseng extract not only protect the skin, but also have the functions of conditioning the skin and promoting skin metabolism, and are very popular. Silk has a good affinity with human skin, is breathable and absorbs water, and has been known as the queen of fibers since ancient times. Silk fibroin is a natural protein extracted from silk, consisting of 18 kinds of amino acids. Studies have shown that silk fibroin has growth-promoting biological activity on most m...
