Qualitative and quantitative analysis of hydroquinone content in both face cream samples was carried out by TLC and HPLC methods. The results of the qualitative analysis by TLC on both face cream samples (X and Y creams) showed that both samples had the same Rf value 1as the standard hydroquinone Rf while the HPLC chromatogram results of both samples had the same retention time as the standard hydroquinone. Simultaneously, the results of quantitative analysis on cream X samples contained hydroquinone of 3.06% and Y cream of 4.15%.
