【Introduction】
Silk peptide is produced by hydrolysis of silk fibroin from silkworms, with molecular weight below 2000, has good water solubility, and can maintain the excellent characteristics of the crystalline area of silk sericin.
【Chemical Properties】
1、It has a natural moisturizing and nourishing effect on the skin. There are numerous hydrophilic groups on the molecular structure of silk peptide, which are on the surface of the three-dimensional structure of the molecule, and this structural surface of silk peptide has an excellent moisturizing effect.
2、It counteracts the production of melanin in the skin. Melanin is a fine particulate substance generated by the oxidizing action of tyrosinase in the melanocytes of the skin. Silk peptide can resist the activity of tyrosinase and thus resist tyrosine synthesis of melanin.
3、It promotes skin tissue regeneration and prevents cracking and chemical damage.Silk peptide is highly effective in promoting the healing of skin wounds.Containing silk peptide cosmetics, to prevent skin cracking also has a good effect. At the same time, it can reduce skin wrinkles, but can’t prevent dust, paint, alkali chemicals on the skin.
4、It has excellent hair care function. The hair care function of silk peptide depends on its absorption and adsorption by the hair, film-forming, moisturizing and humidifying properties.
【Advantages】
1、Silk peptide is produced with high-quality silk raw materials. Cultivation of silkworms on mulberry trees is green, environmentally friendly, and the quality can be controlled and traced.
2、The average molecular weight of silk peptide is less than 2000.The production process is strictly controlled to ensure the absence of biological impurities and high biosafety.
【Grade】
Aseptic, Non-aseptic
【Packaging and Storage】
This product should be stored in a dry environment.
【Application】
Silk peptide products can be used as raw materials for absorbable products, as well as moisturizing cosmetics, skin care products and hair care products.
