Silk Amino Acids-CAS 96690-41-4
Silk Amino Acids is a high-purity natural small-molecule amino acid raw material refined from natural silk through degumming, enzymolysis, purification and drying processes. Different from common synthetic moisturizing ingredients, its molecular structure is highly compatible with human skin and hair tissues, with strong permeability that can penetrate into the basal layer of skin and hair cuticles. It can form a soft and breathable protective film on the surface of skin and hair, effectively lock moisture, improve dry and dull skin and frizzy hair conditions. With mild and non-irritating properties, excellent antioxidant and barrier repair effects, it can significantly improve the delicate and silky touch of daily chemical finished products, and is a core luxury raw material for high-end mild skincare and hair care products.
