Pengaruh Polivinil Alkohol dan Hidroksipropil Metilselulosa terhadap Sifat Fisik dan Sensoris Masker Gel Peel-Off Ekstrak Daun Kelor

Abstract

Peel-off gel masks should spread easily, dry within a practical time, and be acceptable to users. This study evaluated the effects of polyvinyl alcohol (PVA; 10–14%) and hydroxypropyl methylcellulose (HPMC; 2% and 3%) concentrations on the spreadability, drying time, and sensory acceptance of peel-off gel masks containing 3% Moringa oleifera leaf extract. Ten formulations (F1–F10) were prepared. Spreadability was measured between two Petri dishes, drying time was recorded on the inner forearm, and sensory acceptance of color, aroma, and texture was assessed by 30 panelists using a five-point hedonic scale. Spreadability ranged from 5.6 to 6.3 cm and tended to decrease as PVA concentration increased. Drying time decreased consistently with increasing PVA, from 27.26 to 20.43 min in the 2% HPMC series and from 30.01 to 22.97 min in the 3% HPMC series, and 3% HPMC lengthened drying time by 2.3 min on average compared with 2% HPMC. Nine of the ten formulations met the reference ranges for spreadability (5–7 cm) and drying time (15–30 min); F6 reached 30.01 min, marginally above the upper limit. Mean hedonic scores ranged from 4.13 to 4.53. The Friedman test showed no significant differences in color (p = 0.993) or aroma (p = 0.460). A significant overall difference in texture (p = 0.017) was not confirmed by pairwise Wilcoxon tests with Holm correction. Formulations containing 12–14% PVA combined shorter drying times (20.43–26.75 min) with adequate spreadability (5.6–6.2 cm) and good sensory acceptance.
