What Is Sodium Myristoyl Sarcosinate?
Sodium myristoyl sarcosinate is the sodium salt of myristoyl sarcosine. In cosmetics, it functions mainly as a hair conditioning ingredient, emollient, and cleansing agent. Most chemists consider this ingredient a co-surfactant since it works with the primary surfactants to help create an elegant foam and provide stabilization to said foam.
The independent Cosmetic Ingredient Review has found sodium myristoyl sarconsinate safe as it is currently used in cosmetics.
The highest reported leave-on concentration of sodium myristoyl sarcosinate is 5% in eyeshadow formulations.
