Because amino acid with hydrophilic polarity accounts for about 75% in sericin, especially serine which takes up about 30% of sericin, whose hygroscopicify is 50 times stronger than glycerol. Thus, sericin, is highly effective in moisture absorption, moisture, breathable function and antimicrobial function when used as raw material of cosmetic and chemical fiber lay material.
(2)The film-forming property of silk glue on hair is excellent and the membrane is glossy, while the hair feels good and elastic. It can not only avoid the direct contact between hair and chemicals that can damage hair, and it can also increase the elasticity and gloss of hair. Sericin can form the membranes with certain strength on the hair surface, which can be used as the hairspray.
