The purpose of this study was to identify the presence of Rhodamine B in lip creams circulating in Kudus City. The research method was carried out quantitatively because it determined the levels of Rhodamine B using Thin Layer Chromatography (TLC). The lip cream samples studied were 5 samples with different brands and sold at the Kudus City Cosmetics Store.

The identification results of the five samples tested contained two samples suspected of containing synthetic rhodamine B dye, namely samples A and E, this can be seen from the color of the spots seen visually are pink and orange, while under UV light it is purple and fluoresces yellow. For the Rf value of rhodamine B of 0.68, it is the same as sample A, while samples B, C, D, and E have a value of 0.7.
