Antioxidant Activity Test and Peel Off Gel Mask Formulation of Pagoda Flower Extract (Clerodendrum paniculatum L.) with Variations in the Concentration of HPMC and PVA as Gelling Agents

Abstract

The pagoda flower (Clerodendrum paniculatum L.) is one of the ornamental plants that can be developed as a medicinal or cosmetic plant. Pagoda flowers contain chemical compounds, namely flavonoids, tannins, alkaloids, and terpene compounds that can be used as antioxidants. The manufacture of pagoda flower extract is carried out by maceration using ethanol 70%. The extract was then formulated into a peel off gel mask preparation with variations in PVA concentrations, namely F4 (8%), F5 (9%) and F6 (10%) as well as HPMC concentrations of F4 (3%), F5 (4%) and F6 (5%). The antioxidant activity test of the peel off gel mask of pagoda flower extract was carried out by the DPPH method (2,2-diphenyl-1-pikrylhydrazyl). Testing the physical properties of peel off gel masks includes organoleptic, homogeneity, pH, viscosity, adhesion, spreadability, drying time, and stability with the cycling test method. The results of this study show that the physical properties of the preparation meet the standard of good peel off gel mask requirements. IC50 results obtained from F4; 121.29 ppm, F5; 113.02 ppm, and F6; 94.37 ppm
