Synerisis and Cycling Test the Sendok Leaf Extract Gel (Plantago Mayor L.) with Optimization of Variations of Gelling Agent Carbomer 940 Concentration

Abstract

The purpose of this study was to determine the effect of the concentration of the gelling agent Carbomer 940 on the gel of daun Leaf Extract (Plantago major L.). The method used is the experimental method. The extraction method used is maceration with 96% alcohol. The design in this study is the manufacture of a gel formulation of sendok Leaf extract (Plantago major L.) with the concentration of the gelling agent Carbomer 940 and the syneresis test. Syneresis test results show that all formulas do not occur syneresis. The results of the cycling test showed that the sendok Leaf (Plantago major L.) extract gel was not affected by storage temperature. The conclusion of this study shows the effect of variations in the concentration of the gelling agent Carbomer 940 on the quality of gel.
