<![CDATA[ABSTRAK Most of the lip cream products on the market today still use synthetic dyes that may contain carcinogenic heavy metals. To address this issue, natural dyes have become a safer and more environmentally friendly choice. Sappan wood (Caesalpinia sappan L.) and roselle flowers (Hibiscus sabdariffa) are two natural ingredients known to be rich in anthocyanins, thus potentially usable as natural dyes in cosmetics. This study aims to determine the effect of the combination of sappan wood extract and roselle flower extract in lip cream formulations on the physical characteristics and stability of the products. Two formulas were tested: F1 used 1% sappan wood extract (as a control), and F2 was a combination of 1% sappan wood extract and 1% roselle flower extract. Testing included organoleptic parameters, homogeneity, pH, spreadability, and stability. The results showed that both formulas had similar aroma and texture. The color of lip cream F1 appeared pink, while F2 was brick red. Both were homogeneous and had a stable pH at 6. The spreadability of F1 was 5.9 cm and F2 was 5.4 cm, both still within acceptable ranges. However, stability testing using the freeze-thaw method over six cycles showed color changes in F1 and the appearance of granules in both formulas, indicating instability in terms of organoleptics and homogeneity. Overall, formulas F1 and F2 have the potential to be used as natural dyes in lip cream formulations, but improvements need to be made in the manufacturing method to enhance the stability of the preparations. ]]>
