Formulation and Physical Quality Test of Strawberry Leaf Extract Gel Preparation (Fragaria X Ananasa) with Variations in Carbopol 940 Concentration as Gelling Agent

Abstrak

The formulation of gel preparations in this study aims to determine whether sunscreen gel preparations of ethanol extract of strawberry leaves with various concentrations of carbopol 940 can be formulated into gels with good physical quality. Strawberry leaves were extracted using maceration method with 96% ethanol solvent. Analysis of the extract content was carried out by Thin Layer Chromatography (TLC). Concentration of 1% strawberry leaf extract and variations of carbopol 940 0.5%; 1%; 1.5%. Determination of physical quality tests, namely organoleptic test, pH test, viscosity test, spreadability test, adhesion test and stability test. Then, it was analyzed using the Statistical Product and Service (SPSS) program. The test results for strawberry leaf extract gel showed stability and physical quality, where the high concentration of carbopol caused an increase in viscosity and adhesion but reduced spreadability. Gel preparation in formula 2 with 1% carbopol concentration had the best physical quality and stability.
