Science
Mechanism of Action
As an amino acid-based anionic surfactant, Sodium Lauroyl/Myristoyl Aspartate functions by significantly reducing the surface tension between disparate phases like water and oil. This emulsifying action enables the efficient lifting and removal of dirt, excess sebum, and other impurities from the skin and hair. Its design ensures a thorough cleanse without compromising the skin's essential natural lipids, thereby preserving hydration and imparting a smooth, silky post-application sensation.
