Premium Silk Amino Acids (Hydrolyzed Silk Fibroin) – Cosmetic Grade Powder
Product Description
Our Silk Amino Acids, derived from natural silkworm cocoons through advanced enzymatic hydrolysis, offer a high-purity, water-soluble white powder ideal for cosmetic applications. With a low molecular weight (<500 Da), it ensures deep penetration into the skin and hair cuticles, delivering intense hydration, repair, and protection. The product is rich in glycine, alanine, and serine—key amino acids that support keratin binding, moisture retention, and antioxidant activity. It is suitable for vegan formulations when produced via fermentation technology.
