Hydroquinone has been known as an active ingredient in whitening cosmetic preparations. Six (6) whitening night cream samples have been taken randomly from a supermarket in Purwokerto. Hydroquinone in whitening night cream samples was identified by thin layer chromatography (TLC) with methanol : chloroform (1:1) as mobile phase and silica gel F254 as stationary phase. Determination of hydroquinone levels use Ultraviolet-Visible (UV-Vis) spectrophotometry by phloroglucinol reagents addition. The results of the validation of analytical methods including precision, linearity, limit of detection, limit of quantitation, and accuracy showed that the UV-Vis spectrophotometric method can be used to determination of hydroquinone level. The result study showed that five (5) of the six (6) samples containing hydroquinone with varying levels.
