The Study of Damage Rate Tumeric-Aloe vera cream (Curcuma domestica Val. - Aloe vera) on Various Concentrations 0f Phenoxyethanol During Storage.

Abstract

This study aimed to: 1) Determine the effect of phenoxyethanol concentrations as a preservative of turmeric Aloe vera cream. 2) Determine the right phenoxyethanol concentration to produce turmeric-Aloe vera cream  with a longer self life and fulfil the requirement of SNI. This study used a Simple Linier Regression. The  concentration of phenoxyethanol treatment consisted of 6 levels, namely 0% ; 0,2% ; 0,4% ; 0,6% ; 0,8% and 1%. Each treatment was repeated 3 times, so that 18 experimental units were obtained. The data was analysed  using linier regression to showed the damage rate of turmeric-Aloe vera cream during storage. The variables  observed in turmeric-Aloe vera cream are homogeneous, pH, specific gravity, viscosity, total phenol, total  plate count, and yeast fungus score. The results of the study showed that the best concentrations of  phenoxyethanol is 1% : homogeneous, pH 5, specific gravity 1,00130 g/cm3, viscosity 10400 cps, total phenol 6,33176 mg GAE/g, ALT 0 koloni/g dan AKK 0 koloni/g and also that is able to keep the physical properties  of turmeric-Aloe vera cream in 41-53 weeks and can inhibits microbial growth until 6 weeks.
