The invention relates to the field of bristles preparation technology and cosmetic brush technology, in particular to a silk fibroin collagen bristles formula and a preparation process thereof.

Background technique

The bristles of professional makeup brushes are generally divided into animal hair and synthetic hair. The natural animal hair cloth has complete hair scales, so the hair is soft and the powder is saturated, which makes the color uniform and does not irritate the skin.

Scientific research shows that silk contains a large amount of protein fiber and rich silk fibroin and 18 kinds of amino acid active ingredients required by the human body. Silk fibroin has good affinity with human tissues, and silk amino acid sericin has nourish skin and resist Allergies, improve skin cell vitality, eliminate skin melanin, skin, skin care and other effects. Silk protein also has the functions of moisture absorption, heat preservation and absorption of ultraviolet rays.

The existing makeup brush is usually made by using ordinary bristles and a preparation process, and does not contain silk fibroin collagen, and the health care effect is poor, and this problem needs to be solved urgently.

The beneficial effects of the invention are:

1. The preparation process of the invention is simple and the cost is low. The invention adopts the silk protein finishing agent SEW3260, which is suitable for skin care finishing of cotton, wool, silk, hemp, chemical fiber fabrics and garments. After the modified clothes, the summer wears moisture-absorbing and quick-drying, soft and smooth; because the silk protein, amino acid and human skin are similar in composition, the clothing and the skin have affinity, moisturizing, moisturizing, conditioning, enhancing gloss and elasticity. effect. When the finishing agent is used in the bristles, amino acids and the like can be infiltrated into the skin surface during the bristles, thereby moisturizing, moisturizing, conditioning, enhancing gloss and elasticity. During use, as the bristles wear, the end faces of the bristles gradually move, so that the microcapsules are always broken to release the contents.

2. It is proved by statistics that the makeup brush of the invention has a possibility of more than 99% whitening effect than the ordinary makeup brush, and the whitening effect is superior.

3. At present, the bristles used in makeup brushes on the market are made of dyes and traditional techniques. With the development of society, human beings pursue the quality of life and pay attention to safety. After two years of research and development, we have invented nano-microorganisms. The bristles will be suitable for use in makeup brushes, wig beauty tools, accessories and other fields. The invention is widely used for medical treatment, and proves to be safe and efficient, non-irritating to the skin, non-toxic and non-allergic.

Example 2: Experimental design and experimental results of antibacterial effect

Referring to Figures 1 and 2, 80 volunteers were randomly selected and divided into four groups of A, B, C, and D, each group containing 20 members. The face of each volunteer was divided into four areas, which were divided into A area 10, B area 20, C area 30, and D area 40. The A zone 10 uses the makeup brush prepared by the prescription A, the B zone 20 uses the makeup brush prepared by the prescription B, and the C zone 30 uses the makeup brush prepared by the prescription C. Brush each face with a makeup brush (do not brush the cosmetics) every day for 5 minutes. After 15 days, at the end of the 15th day, the degree of darkness of the skin was measured using a Visia skin tester.
