Objective: Halal cosmetic products cover all aspects of the production process, including the starting raw materials, handling, processing, storage, distribution, transportation, and delivery to consumers. For this reason, detection of lard on the facemask products is very important to ensure the halalness of the cosmetic products used. The purpose of this study was to analyze the lard on the face mask samples containing olive oil which the products did not have a permit from The Indonesian Drug and Food Control (BPOM) by using Fourier Transform Infrared (FTIR) Spectroscopy combined with chemometric. Methods: The code of samples is LTL, QN, NR, MDG, and HCN. The control of the research is lard and olive oil. The data from the FTIR spectrum is combined with a Principal Component Analysis (PCA) analysis of chemometrics. The combination is quite effective and accurate for analyzing the mixture of oils in face mask samples. Result: The MDG sample shows the presence of the C=C cis functional group in the wave region of 1664.74 cm-1. On the wavenumber area of 1546.17 cm-1, it indicates the presence of a C=C aromatic functional group. The wavenumber region on 1065.70 cm-1 indicates the presence of a C-O functional group (ester, CA). Based on the pattern of the spectrum related to the wavenumber area that appears in lard, the MDG sample is suspected to contain lard. By the PCA chemometric graph, the MDG and lard samples are located in the same quadrant. Conclusion: The research shows that the MDG sample contains lard that this not written on the packaging label.
