Sodium Lauroyl Sarcosinate,Cosmetic Grade Sarcosinate(CAS 137-16-6)
Cosmetic-grade Sodium Lauroyl Sarcosinate is a high-quality amino acid-derived anionic surfactant synthesized by advanced condensation technology. Different from traditional sulfate surfactants, it has mild amino acid molecular structure, extremely low skin and eye irritation, and is a mainstream mild cleaning raw material in high-end personal care products.
The product has excellent foaming performance, producing rich, fine, dense and elastic foam, which can wrap and remove skin surface oil, dirt and residual makeup efficiently without destroying the skin natural sebum barrier. With unique low-degreasing formula characteristics, it avoids tight, dry and rough skin after cleaning, leaving soft, smooth and non-tacky skin feeling.
It has outstanding hard water resistance, maintaining stable cleaning and foaming effects in hard water environment without scale residue. Meanwhile, it has mild antibacterial and anti-dandruff activity, which can inhibit the growth of harmful bacteria on skin and scalp, relieve scalp itching and oily dandruff problems, and improve scalp microenvironment.
It features stable physical and chemical properties, wide pH adaptation range, excellent compatibility with non-ionic, amphoteric surfactants and various moisturizing and soothing ingredients. It can effectively reduce the irritation of strong surfactants, optimize formula mildness, and is the core base material for high-end mild amino acid cleaning products, suitable for sensitive skin, infant and pregnant skin low-load cleaning care.
