"Sodium" means the element sodium. The name component "myristoyl" means that the ingredient contains among others myristic acid (tetradecanoic acid) as fatty acid component. Sarcosinates are N-acyl derivatives of sarcosine (N-methylglycine, an amino acid).

Sodium myristoyl sarcosinate is a substance used in cosmetic preparations where it acts as a surfactant (washing-active substance), antistatic agent (reduces static charges by neutralizing the electrical charge on the surface of e.g. hair), hair conditioning agent (makes hair easy to comb, smooth, soft and shiny and gives it volume) and viscosity regulator (increases or decreases the viscosity of cosmetic products).
