Abstract

This research was aimed to know the effect of ptotato skins ethanolic extract variation concentration to physical properties of gel and antibacterial effect to Propionibacterium acnes. Gel were formulated in 3 formulas with potato skins concentration 50%, 60% and 705 respectivelly. The phisical properties of gel which obeserved include organoleptic, homogenity, pH, and spreadability. The results show that variation concentration of potato skins ethanolic extract has an effect to gel colour and viscosity but has not effect to form, smell, pH, and spreadability of gel. All formulas show strong inhibition power to Propionibacterium acnes.

Abstract

Gel is a semisolid dosage form that consumers prefer because of its cool sensation. This research aimed to identify the effect of different concentrations of ethanolic extract from potato peels on the physical properties and the antibacterial activities of the resultant gels against Propionibacterium acnes. The gel was prepared with three formulas using a variety of potato peel concentrations, namely 50%, 60% and 70%. Its physical properties were analyzed based on organoleptic observation, homogeneity, pH, and spreadability. The results showed that the ethanolic extract of potato peels affected the color and viscosity of the gel. However, no effects were detected on shape, smell, pH, and spreadability. All formulas showed strong inhibitory capacity against Propionibacterium acnes.
