Formulation And Optimization Peel-Off Gel Mask with Polyvinyl Alcohol and Gelatin Based Using Factorial Design from Banana Peel Flour (Musa paradisiaca L) As Antioxidant

Abstract

Banana peel (Musa paradisiaca L) contains flavonoid compounds that act as an antioxidant that has the potential to be developed into cosmetic preparations such as peel-off gel masks. This study aims to determine the effect of variations in the concentration of banana peel flour, PVA, and gelatin on the physical properties of peel-off gel masks and to determine their antioxidant activity. This study uses a factorial design of 23 where the factors used are the concentration of banana peel flour, PVA, and gelatin with 2 levels. Based on the results of data analysis, it was found that there was a significant effect of each factor and the interaction between factors on the spreadability and drying time of the preparation (p<0.05). F5 with a concentration ratio of banana peel flour, PVA, and gelatin of 5:12:5 was chosen as the optimum formula and continued to antioxidant activity test compared to F4 which had a ratio of concentrations of banana peel flour, PVA, and gelatin of 10:14:3. The antioxidant activity produced by F5 was better than F4 with IC50 values ​​of 525.41 and 355.64 ppm, respectively. It can be concluded that the optimization of the dosage formula will affect the activity of the active substance.

Formulation, Characterization and Optimization of Peel-Off Gel of Soybean Extract as a Face Mask

“…The higher the concentration of PVA used, the more the viscosity will increase due to hydrogen bonding occurring between the OH group of PVA, and the water used in the composition. 20 This finding supports the research of Asthana and colleagues that shows that increasing or decreasing the PVA concentration is not beneficial for the uniformity and thickness of the PVA film. 22 How fast the material spreads depend on how much force is applied, for how long, and how thick the material is.…”

“…18 This observation supports the research of Apriani and colleagues, where PVA was shown to interact with water, absorbs the liquid and forms a thick mass that causes the liquid to be trapped and difficult to evaporate, leading to a prolonged or increased drying of the formula. 20 The ethanol variable also negatively influenced (coefficient= -6.84) the drying time (Table 4). This is because ethanol helps things dry faster, and it evaporates more quickly than water.…”

“…Telah banyak penelitian membuktikan manfaat dari tanaman sebagai bahan baku kosmetik seperti kulit pisang kepok, kulit manggis, biji alpukat, tongkol jagung, daun mawar, daun sambiloto, daun kemangi, minyak kelapa dan lain sebagainya. Kulit pisang kepok terbukti memiliki manfaat sebagai antioksidan dan anti jerawat karena kandungan flavonoid, tannin, alkaloid, saponin dan polifenol (Apriani et al, 2022). Kulit manggis juga terbukti memiliki manfaat sebagai antioksidan yang dapat digunakan untuk penuaan dini pada kosmetik (Miksusanti, Apriani, & Aprida, 2023).…”
