ABSTRACT

Synopsis

The aim of this study was to develop a technique to assay for the activity of antioxidants in a finished cosmetic product. This was accomplished by adapting the Randox Assay for Total Antioxidant Status kit so that diluted samples could be evaluated by kinetic as well as end-point determinations. Using this technique, we found that a finished product had an IC 50 of 0.07 gm of product and a relative antioxidant activity concentration of 52.7 nmoles\/mg.
