Abstract
The high purity silk peptide powder can be obtained by the method of atomizing drying after the boiled silk (sericin) is decolorized, enzymatic dissolved, ion exchange purificated and concentrated. It can be used as the additive of high-grade cosmetics. The amino acid components of sericin provide excellent moisture absorption and retention on the skin. The molecular weight size of sericin will directly affect the types of cosmetic application. The results show that the sericin can inhibit the activity of tyrosine and the formation of melanochrome effectively. Through the experiment and SEM observation, we discovered that the sericin on the hair provides excellent hair care and repair effect. The application of sericin in cosmetics will provide parameter value of experimental evidence for developing new varieties of sericin in cosmetics.
