Abstract

Cream is a semi-solid preparation in the form of an emulsion containing one or more drugs dissolved in a suitable base material and containing not less than 60% water. Emulsifier is an active ingredient that has a function to reduce the surface tension between water and oil. The aim of this study was to determine the effect of variations in stearic acid and triethanolamine on the formulation of onion skin extract cream (Allium ascalonicum L.) on physical quality and stability tests. The extraction method used in this study is extraction with 96% ethanol. Cream preparations were made with three formulas with variations of stearic acid 14%, 15%, 16% and TEA 4%, 3%, 2%. The cream was tested for physical quality including organoleptic test, viscosity, pH, homogeneity, adhesion, spreadability, stability. The results of the study were analyzed using SPSS. The results showed onion peel extract can be made into cream preparations that increasing the concentration of stearic acid had an effect on increasing viscosity, increasing pH, decreasing dispersion and conversely increasing concentrations of TEA had an effect on decreasing viscosity, adhesion and increasing dispersibility.
