Uses
Given its foaming properties, the derivatives of lauric acid (h-dodecanoic acid) are widely used as a base in the manufacture of soaps, detergents, and lauryl alcohol. Lauric acid is a common constituent of vegetable fats, especially coconut oil and laurel oil. It may have a synergistic effect in a formula to help fight against mircoorganisms. It is a mild irritant but not a sensitizer, and some sources cite it as comedogenic.
