The analysis was carried out descriptively based on the results of the homogeneity test, melting temperature test, pH test, stability test, and preference test. Results: The results showed that the Lip balm preparations of the four formulas showed 75% homogeneity. Then the melting temperature of all preparations meets the requirements of the SNI melting point standard (500-700C). The acidity level (pH) of all preparations also meets the requirements of cosmetic pH standards (4.5 – 6.5). Meanwhile, the stability of all Lip balm formulations is stable in color (100%), stable in smell (100%), and stable in shape (85%).
