Physical Evaluation Test Of Serum Facial Ethanol Extracts Of Purple Passion Fruit Peel (Passiflora edulis Sims)

Abstract

A facial serum is a slightly viscous liquid that contains active ingredients to treat skin problems. Purple passion fruit peel extract is proven to contain flavonoids and tannins, which have antibacterial activity that causes acne. Hence, it is necessary to test the formula (F) of facial serum with the composition of ethanol extract of purple passion fruit peel, niacinamide, carboxymethylcellulose sodium, and distilled water. The concentration differences in the percentage of ethanolic extract of purple passion fruit peel were 4%, 5%, and 6%. This type of research is quantitative with a pre-experimental design. A phytochemical screening test was carried out on the presence or absence of flavonoids and tannins. Physical stability tests were carried out by organoleptic, homogeneity, pH, and viscosity tests for 30 days of storage. Data analysis was performed with a descriptive test. The phytochemical screening test on the flavonoid test was positive, and the tannins were positive. The results of the physical stability test only yielded stability until the 5th day, when the organoleptic test did not change color and smell; F1 was pale yellow, F2 was yellow, and F3 was dark yellow and had a distinctive aroma of the extract. pH test results at F1 4% (6.22-6.28), at F2 5% (5.93-6.28), and at F3 6% (5.41-5.82). In the viscosity test, F1 4% (1.833-5.667 cP), F2 5% (3.333-8.000 cP), and F3 6% (4.167-12.000 cP). The homogeneity test for the three formulas showed homogeneous results. In this study, the best formula cannot be achieved because, during stability testing for 5 days of storage, the viscosity decreased with a percentage of 67% F1, 58% F2, and 65% F3. It can be found that the facial serum preparation became liquid and unstable.
