Utilization of Anthocyanin Extract from Clitoria ternatea as a Natural Colorant in Eyeshadow Formulation

Abstract

In recent years, butterfly peas flowers (Clitoria ternatea) have gained popularity as natural colorants such as cosmetic, pharmaceutical, textile, and food colorants. Especially as the cosmetic colorant, Clitoria ternatea has been used as a nail and hair colorant. The blue color of Clitoria ternatea is primarily due to anthocyanin content. In this research, Clitoria ternatea was utilized as a natural colorant in the formulation of compact powder eyeshadow. This research aims to produce anthocyanin extract from Clitoria ternatea through extraction and vacuum evaporation processes at optimum conditions and to utilize the extract in eyeshadow formulations. Clitoria ternatea was extracted in stirrer-equipped extractor using an ethanol solvent at 50°C for 30 minutes, then concentrated with a vacuum evaporator at 65°C. The results indicated that the total anthocyanin extracted from Clitoria ternatea was 2.889 mg/g. Compact powder eyeshadow was prepared in four different formulas and contained Clitoria ternatea extract concentration of 4% (F1), 8% (F2), 12% (F3), and 16% (F4). Each formula was evaluated by conducting organoleptic, pH, spreadability, irritation, and hedonic tests. The results of F2, F3, and F4 showed stable and more intense color production. The most optimal formula is F4 due to the highest enthusiast on the hedonic test.
