Silk Amino Acids, also known as Fibroin-90, are water-soluble mixed amino acids derived from the hydrolysis of natural silk fibroin. The average molecular weight of these acids is approximately 90.
The powder form is a creamy white, highly soluble powder with a total nitrogen content of ≥15%. The liquid form is a faint yellow transparent liquid with a solid content of approximately 20% and a total nitrogen content of ≥3%.
The product features a high concentration of primary amino acids, with the combined content of Glycine, L-Alanine, and L-Serine accounting for ≥83% of the total amino acid profile.
Due to their moisturizing, nourishing, and protective properties, they are widely utilized in cosmetics, personal care products (such as hair care and skin care formulations), and dietary supplement industries.
Yes, all batches are rigorously tested. The heavy metal content is kept strictly below ≤5 mg/kg (for powder) and ≤1 mg/kg (for liquid), with pathogenic bacteria being completely undetectable.
They should be stored in a cool, dry place in tightly sealed containers to prevent moisture absorption. Proper storage ensures prolonged shelf life and stability.
