Silk Amino Acids PF

CAS No. 96690-41-4, 7732-18-5 (water) Hydrolyzed from pure silk fibers, silk amino acids have a lower molecular weight than hydrolyzed silk protein powders as they undergo a greater degree of hydrolysis. Due to their smaller molecular weight they are more penetrating and moisturizing to skin and hair. Our Silk Amino Acids PF (Paraben Free) have a high concentration of amino acids, providing greater benefits than ever before! The principal amino acids in Silk Amino Acids  are glycine, alanine, and serine. The bulk of the other major amino acid, tyrosine, has been removed due to its lack of solubility. Highly substantive to skin and hair, Silk Amino Acids PF are highly hygroscopic and have excellent moisture binding ability. Free amino acids are known to penetrate into the upper layers of the skin as well as through the hair cuticle into the hair shaft. This draws moisture into these areas, improving skin and hair hydration. For hair, this results in increased flexibility and manageabili
