Coenzyme A

What is Coenzyme A?

Coenzyme A, or CoA, is a naturally occurring coenzyme present in all living cells, derived from pantothenic acid (vitamin B5). Chemically, it features a pantetheine unit attached to adenosine diphosphate, enabling it to act as a carrier for acyl groups in biochemical reactions. In skincare products, it falls under skin conditioning agents, emollients, and solvents, commonly appearing in creams, lotions, and serums. It works by interacting with the skin's surface to promote a soft, smooth feel, reducing roughness while helping to blend and stabilize other formula components. As a solvent, it aids in controlling product viscosity and even delivery of actives in both aqueous and oily bases, enhancing overall texture without adding greasiness. Its mild nature supports comfortable application across various formulations.
