Products Description of Sodium Lauroylsarcosinate CAS#137-16-6
Sodium Lauroyl Sarcosinate (also identified as sodium lauroyl-N-methylaminoacetate or sodium lauroyl-N-methylglycinate) is a ultra-mild, amino acid-derived anionic surfactant. In modern cosmetic chemistry, it plays a vital role as a primary or secondary cleanser, lather booster, hair anti-static agent, and skin conditioner.
Carrying a favorable safety rating (EWG Risk Score ~3), it is widely recognized as a safe, non-disruptive ingredient suitable for sensitive skin applications, pregnancy-safe personal care, and non-acnegenic formulations.
