Evaluating Essential Oils in Cosmetics: Antioxidant Capacity and Functionality
In the present work, the antioxidant capacities of three essential oils derived from basil and thyme were evaluated using a photochemiluminescence (PCL)-based assay. In addition, since the base formulation can affect the antioxidant activity of oils contained therein, ingredient interactions within final formulations were investigated.
