EFFECT OF STORAGE TEMPERATURE TO DETERMINE HYDROQUINONE IN FACE CREAM BY SPECTROPHOTOMETRY

Hydroquinone is often used as a bleach in face creams. Hydroquinone is an effective substance against skin whitening but has damaging side effects if used long term. Basically hydroquinone does not work as a skin whitener, but inhibits the production of skin melanin. The purpose of this study was to determine differences in hydroquinone levels in face cream before and after treatment with different storage temperatures. This study was conducted using spectrophotometry at a maximum wavelength of 280 nm. As for this study using variations in storage temperatures are 24°C, 31°C and 3°C, and before treatment at 28°C. Hydroquinone levels were obtained with the lowest levels of 0.113 ppm in sample C stored at 24°C and the highest levels of 0.518 ppm in sample A without treatment at 28°C. Based on this study, it was concluded that in sample A there was a difference between the sample before and after treatment. While in sample B and sample C there is no difference between the samples before and after treatment.
