Abstract

Annatto seeds (Bixa orellana L.) contain natural pigments, namely bixin and norbixin. Bixin can produce a reddish-orange color, commonly used as a natural colorant in food, textiles, and cosmetics. However, annatto seeds are still never used in compact powder eyeshadow formulations. This research aimed to produce bixin extract from Bixa Orellana L. through extraction and vacuum evaporation processes, and to determine the optimal bixin extract as a natural colorant in compact powder eyeshadow formulation. The extract was obtained by an extraction process using ethyl acetate as a solvent. The extraction process was done in a stirred extractor at 50°C and 300 rpm for 90 minutes. The extract was then concentrated using a rotary vacuum evaporator at 35°C, followed by centrifugation for 10 minutes. The result of the bixin extracted from annatto seeds was 10.48 mg bixin/gram, while the yield was 1.2%. The compact powder eyeshadow formulations were prepared at bixin extract concentrations: 10% (F1), 20% (F2), and 30% (F3). The evaluation of the compact powder eyeshadow formulations included organoleptic, homogeneity, spreadability, irritation, and hedonic tests. The result was the F2 formula, which indicated the most optimal formulation based on the evaluation conducted.
