Abstract
Lipstick is one of the cosmetics products favored by most women in Indonesia. However, in 2014 BPOM found that some cosmetics brands contain rhodamine B synthetic pigments that are dangerous and capable of irritation. On the other hand, Indonesia has increased production of purple sweet potato tubers in 2013. Purple sweet potato tubers contain many nutritious compounds, such as anthocyanin which has potential as a natural red-purplish (violet) dye both in food, medicine, and cosmetics. Unfortunately, anthocyanins are unstable against high heating, pH changes, enzymes, light, metal ions, and oxidation. The purpose of this study is to protect anthocyanin from the degradation process and application of anthocyanin use of extract of sweet potato termic microencapsulation to physical stability, especially color of lipstick preparation. The method used in the study was microwave-assisted with the help of microwave radiation drying. The ratio of maltodextrin DE 10 coatings; gum arabic; combination of maltodextrin gum arab (1: 1) with ethanol extract of sweet potato tuber of purple (2: 1)% and (3: 1)% w / w. Dry purple sweet potato tuber powder (Ipomoea batatas L.) was extracted with 70% ethanol in acidic atmosphere, thickened. The viscous extract is then micro-encapsulated. The microencapsulated optimum formula was then made into lipstick and tested for its physical properties including organoleptic and homogeneity tests, strength, pH test, melting point, and physical stability. The data were analyzed by Analysis of Variance (ANOVA) one-way method, 95% confidence level with the result of physical characteristic test of microencapsulation in formula III yielded humidity value 2,44 ± 0,03%, particle size ± 304 μm, 51.78 ± 0.06% with better stability at 28 ° C compared with the other five formulas. Based on the results of the study, there was no comparison and maltodextrin DE 10 and gum arab (2: 1)% w / w as microencapsulated pigment wall of purple sweet potato tuber biocyanin against color of lipstick preparation.
