But the rise of cosmetic products on the market, especially online marketplaces, is an opportunity for weak supervision by drunken parties. For this reason, qualitative and quantitative analysis of hydroquinone compounds in whitening cream preparations sold on online marketplaces needs to be carried out. Qualitative analysis was carried out by testing the color reaction using FeCl3, benedict, and fluoroglucine reagents. From the qualitative analysis, 2 hydroquinone positive samples were obtained from 10 tested whitening cream samples.
