Silk fibroin (silk protein hydrolysate) is a natural moisturizing factor (NMF) with the amino acid content of silk protein,which can beneficially rebuild the skin's moisturizing system.Silk fibroin serum is known for its excellent moisturizing and anti-aging properties,as well as soothing and antioxidant effects.Silk fibroin hydrogel has a significant antioxidant effect and forms a protective peptide coating to protect the skin from harmful effects.It retains moisture and provides a soft touch.The silk fibroin film was developed to accelerate wound healing and can be peeled off without damaging the newly formed skin.
Definition Silk amino acid (SAAs) also known as silk fibroin ,is a natural water-soluble amino acid powder with glycine, alanine and serine content of more than 85% ,it is extracted from raw silk and produced through series process of silk degumming, enzymolysis , acidolysis and dried. The average molecular weight is about 90 ,also named as silk fibroin-90. products specification: Appearance White powder Total Nitrogen 16% min GLY+ALA+SER 85% min Heavy metal 5ppm max Total amino acid 90% min PH 5-7 Water Solubility 100%
Sericin powder amino acids is made from pure silk elements including 18 kinds of amino acids among with L-alanine, L-serine and so on. Sericin powder amino acids is the water soluble mixing amino acid obtained after hydrolysis of Silk fibroin. The average molecular weight is about 90 and the product is also called as "Silk 90". The product is white powder with pH value between 5 to 7 and positive ninhydrin reaction.
