Silk protein (fibroin peptide) can protect the hair and principle

1.Fibroin peptide has good moisturizing and damping effect.

Fibroin peptide has good moisturizing and damping effect. In temperature 27 ℃, relative humidity 86%, temperature humidity box, after 12 h, detection of fibroin peptide ability of moisture absorption.Experiments show that the fibroin peptide solution concentration was 2.4%, the rate of moisture absorption of moisture absorption rate is equal to the concentration of 48% glycerin. The fibroin peptide concentration is lower than the glycerin concentration 20 times still have the same moisture absorption ability. This basically is natural fibroin peptide conformation of curly structure without rules, peptides are loose disorder, many hydrophilic group polypeptide chain (OH, COOH, NH2, etc.) are at the molecular surface of space, the hydrophilic group can absorb moisture, and keep a certain its mechanism is the same as the natural damping factor in the human body. At the same time, the fibroin peptide form a layer of film in the surface of the skin and hair, to prevent too much water evaporation, regulating surface moist degree of small space. When the humidity is high, membrane absorption part of moisture. When the outside world is too dry, film release part of the absorption of moisture, by constantly absorbing humidity and release moisture.

Fibroin peptide can effectively inhibit the production of melanin in the skin.Human epidermal layer exist a kind of melanocyte, in under the action of tyrosinase generated melanin oxidation reaction.

To find out the fibroin peptide inhibit melanin formation mechanism, the experiment of dilute solution with blood as a benchmark solution, adding different concentrations of fibroin peptide solution, using spectrophotometer to determine the inhibition of melanin, when the concentration of fibroin peptide was 25%, the generation of melanin inhibiting rate is as high as 70%, this is other cosmetic additives do not match.

2.Silk fibroin peptide application in cosmetics and effects

Sorts of protein in the skin contains more than any organ, when protein malnutrition, skin appears erythema, desquamation and knit crack obviously, these all have close relationship with metabolic disorder of protein.And silk is a kind of precious natural protein fiber, 97% pure protein, especially in the side chain hydrophilic amino acid (e.g., aspartic acid, glutamic acid, etc.) to be beneficial to human skin.Experiments show that the long-term use of cosmetics have mulberry silk protein in the metabolism of skin, prevent premature skin aging, add vigor has tonic effect, and mulberry silk peptide containing ten many kinds of amino acids, they are extremely similar with skin contains amino acids, had no eyewinker stimulation effect on the skin, it is a good additive.

Used in cosmetics, "fibroin peptide" by the relevant clinical validation show that contain fibroin peptide protect skin to taste, to promote skin metabolism, reduce facial wrinkles, delay the aging skin, moisturize, nourish skin has obvious effect. And for the treatment of skin itching, scar hyperplasia, skin pigment deposition has obvious curative effect, the efficient of 85%consist high praise by the user .
