The present work is based on a study of the effect of some vitamins such as riboflavin (RF), nicotinamide (NA) and alpha-tocopherol (TP) on the photodegradation of ascorbic acid (vitamin C) (AH2) in oil-in-water cream formulations using a UV irradiation source. A UV spectrophotometric and the official iodimetric methods have been used for the assay of AH2 in cream formulations. These methods have been validated in the presence of RF, NA and TP before their application to the creams. The recoveries of AH2 in the creams are in the range ...
