KELISILK™

Water soluble silk hydrolysate derived from pure silk fibroin; contains about 30% of free amino acids and has an average molecular weight of about 400 D. Free amino acids and small peptides form an optimum balance that provides excellent feeling and film-forming properties; due to their ability to retain water they form a plastic and protective film on skin giving softness and a distinct feeling of smoothness. Combined with surfactants can reduce the denaturing effect of surfactants in cleansing formulations. KELISILK can be used both in skin and hair products and in decorative cosmetics. Full water solubility. Compatible with ionic and nonionic surfactant solutions.
