Lipstick is classified as decorative cosmetics, generally, with many colours’ variance attracting the consumers. However, red is the favourites amongst them. Protecting the consumer’s health, lipstick should meet certain requirements which is registered by (National Agency of Drug and Food Control (Badan Pengawas Obat dan Makanan/BPOM). Regulation of BPOM No.HK.03.1.23.08.11.07517 of 2011 regulates prohibited red colorants such Rhodamine B. While at regulation of BPOM No.HK.03.1.23.07.11.6662 regulates a maximum level of heavy metals concentration. This study was conducted to determine the presence of Rhodamine B, Red Allure, and Amaranth as well as Pb and Cd in illegal brands of red lipstick at PXXX Market in Surabaya. The red colorants were identified with Thin Layer Chromatography (TLC)-densitometry while the metals, lead (Pb) and cadmium (Cd), were analysed with Inductively Coupled Plasma Spectrometer (ICPS). A validation method both for TLC-densitometry and ICPS were performed previously prior the analysis; meet the requirements for linearity, accuracy, precision as well as limit of detection (LOD) and limit of quantification (LOQ). Six illegal brands of lipsticks were identified at PXXX Market in Surabaya. One of them was qualitatively detected contains only Rhodamine B, 2 samples contain both Rhodamine B and Red Allure while the rest of 3 brands were contain Red Allure. None of them contain Amaranth. Hence, a quantitative analysis of Red Allure was further conducted. The Red Allure content in the identified red lipsticks was 34.19-187.88 mg/kg, below the maximum allowable content. In case of heavy metals, Pb and Cd. None of the lipstick’s samples contain both Pb and Cd.
