plant extract description

Silk peptide powder is a degradation product of silk protein, which is obtained by hydrolysis of natural silk under appropriate conditions. Silk peptide products with different molecular weights can be obtained without controlling the conditions. The molecular weight is generally between 500-2000d.

Silk protein has long-lasting moisturizing power. According to experimental data, under the environment of 25℃ and 50% humidity, the moisturizing power of Silk Peptide is about 95% after three days.
At present, there have been a large number of research reports on silk protein scaffold materials at home and abroad, such as silk protein nanofibers, silk protein sponge scaffolds, silk protein membranes and silk protein tubes, etc., which are widely used in tissue engineering scaffold materials, drug sustained release materials, photonics Crystal materials, electronic devices and other fields.

plant extract function

1. Silk is a protein fibre with chemical properties akin to human skin. This is why silk protein is an excellent choice for skin care products.Silk peptide contains 18 types of amino acids and is a popular component in skin care products due to its moisturizing, skin elasticity-enhancing, antioxidant, and nutritional properties.

2. It efficiently inhibits melanin formation in the skin.
The trials used silk peptides with molecular weights ranging from 300 to 2000 with concentrations of 10%, 20%, and 50%, respectively.
The results showed that the silk peptide with molecular weights between 300 and 2000 and concentrations of 10%, 20%, and 50% suppressed melanogenesis by 50.9%, 70.9%, and 83.7%, respectively. Furthermore, short molecule silk peptide reduced melanin formation more efficiently than large molecule silk peptide.

3. Bulk Silk peptide powder is also used in the composition of foundations and concealers, where it may aid in film creation and smoothing.
4. Exceptional hair conditioning.
Silk peptides have strong film-forming and moisturising capabilities, which contribute to their hair conditioning properties.
5. Silk peptide has a structure comparable to keratin in hair and binds well to it. Small molecular weight silk peptides can produce a thin, breathable protective coating on the hair's surface, enhancing elasticity, softness, and wetness.

plant extract application

1. Silk peptide powder is the source material of filamentous nutritional lipid inclusions, which are a lipid inclusion additive for boosting functional nutrition in cosmetics, health products, and food.

2. Silk protein is an important natural biopolymer material with excellent biocompatibility, biodegradability, and ease of chemical modification, making it an important biomaterial in regenerative medicine research.
