PENGARUH VARIASI KONSENTRASI ASAM STEARAT DAN TRIETANOLAMIN TERHADAP EVALUASI FISIK SEDIAAN LOTION EKSTRAK DAUN STROBERI (Fragaria x ananassa var Duchesne)

Abstract

Strawberry leaves contain flavonoid, tannin, and saponin compounds that have the potential as ultra protection sunscreen with an SPF value of 52.90. Therefore, strawberry leaves have the potential to be used as active ingredients in sunscreen in the manufacture of lotion formulations. This study aims to determine the formulation and physical evaluation and the effect of variations in emulsifier concentration on the physical properties of strawberry leaf extract lotion preparations (Fragaria x ananassa var duchesne). The manufacture of strawberry leaf extract uses the maceration method with 96% ethanol solvent with a ratio of simplicia and solvent of 1:10. Lotion is made by varying the concentration of triethanolamine and stearic acid F1 (2%: 10%), F2 (3%: 11%), and F3 (4%: 12.5%). The physical evaluation carried out includes organoleptic tests, homogeneity, pH, spreadability, adhesion, viscosity, lotion type and hedonic. The results of the homogeneity and homogeneity tests of the three formulas showed that homogeneous preparations had the same color, odor, and texture. All lotion test results have met the requirements with pH in the range of 5.30±0.03 - 5.44±0.04; spreadability 5.28±0.098 - 6.35±0.360 cm; adhesion 6.23±0.394 - 10.29±0.443 seconds; viscosity 3914.1±0.91 - 3914.8±0.50 cps. Variations in the concentration of stearic acid and triethanolamine significantly affect the pH test, spreadability, adhesion and do not significantly affect the viscosity test.
