Abstract
Aloe vera pulp extract potentially has antioxidant activity because it contains flavonoids and vitamin C. The study, extract was formulated into a cream preparation. The purpose of this study was to obtain the optimum formula cream of aloe vera meat extract using triethanolamine and stearic acid emulsifier based on Simplex Lattice Design methods. Aloe vera pulp extract obtained by maceration using 96% ethanol solvent was then evaporated using an evaporator to obtain a viscous extract. The cream were formulated with a combination of 3 varions emulsifier concentrations, 100% stearic acid (FI), stearic acid : triethanolamine 50% : 50% (FII), and 100% triethanolamine (FIII). The cream were tested for their physical properties including organoleptic, homogeneous, viscosity, dispersive power, pH, shifting viscosity, and the antioxidant activity by DPPH method. The formula optimum parameters was based on physical properties: viscosity, dispersive power, shifting viscosity, using softwere Design Expert version 8.0.6. The obtained optimum formula were made into cream and tested its physical properties and analyzed using t-test. The optimum formula of aloe vera pulp extract cream, it was the obtained proportion of stearic acid 1,157 % and triethanolamine 2,843 %. The activity antioxidant optimum formula of aloe vera extract cream 10% was 203,80 ppm. Keywords: antioxidants, extracts of aloe vera pulp (Aloe vera Linn), Simplex Lattice Design, cream.
