| Summary: | The purpose of this study was to develop a physically stable emulsion with palm oil as the oil phase and incorporated with Melastoma malabathricum Linn flower extract. M malabathricum L is a common shrub that can be found in roadside along Malaysia and Indonesia. M. malabathricum L is widely used in traditional medicine especially among Malaysian. Flower extract of Melastoma malabathricum contain kaempferol-3-O-(2",6"-di-O-p-trans-coumaroyl) glucoside which have been shown to exert antibacterial and anti-inflammatory properties. In this study, several cream formulations are formulated to produce most stable cream with incorporation of this flower extract. The flower extract was obtained by extraction with methanol as a solvent and by using non-reflux method. The stability, particles size, particle size distribution, pH and viscosity of all cream formulation were tested and were compared in between different formulation and in between similar formulation with and without extract incorporation. All formulation used the same excipients with different ratios. Palm oil and cetyl alcohol was the main constituent of oil phase, stearic acid as surfactant, cetrimide as preservatives and distilled water as vehicle. All formulations were made to achieve skin pH that is 5.5. Each formulation produced different physicochemical properties. Formulation of blank creams shows higher uniformity of particle size than creams with extract incorporations. Blank formulation will also have higher viscosity and behave more elastically then creams with extract incorporations. Formulations 5 that have lower water content and with extract incorporation shown to have most stable dispersion system as it produces separation of 0mm/year after tested with Lumifuge dispersion analyzer. |
