Silk Peptide is a albumin product, which can be obtained after hydrolysis from silk, contains 18 kinds of amino acids. It has below 2000 molecular weight can be easily absorbed by human body.
Silk Peptide can be used in cosmetic as a natural material, protecting and keeping the moisture of one’s skin, preventing skin cocking and aging. It’s super absorbency and adsorption enable protect and care to one’s hair. The function and security fibroin makes in cosmetic bears comparison with any other compound material.
Silk Peptide has a bright potential be used as biomedicine remedy and biologic gas defense material.
