Henna is popular among women being a decorative thing for nail and skin. Henna usually made in paste inside tubes so it can be applied easily and long lasting?In this experiment, Henna?s extract will be a coloring agent for waterbased nailpolish. Henna was extracted in aquadest. Waterbased nailpolish made from gelling agents (HPMC, Viscolam, and Carbopol), triethanolamine, methyl paraben, propyl paraben, propylene glycol, ethanol, Henna?s extract, and aquadest?Optimization of formulation included variation of gelling agent, ethanol, and triethanolamine?s content. F9 is the best formula that consists of 5% Viscolam MAC 10; 1,6 mL triethanolamine; 0,15% methyl paraben- ?,?????propyl paraben- ?????propylene glycol- ?,??????Henna?s extract- ??????ethanol- and ad 100% aquadest. Waterbased nailpolish?s evaluation are organoleptic, application, solubility in water, pH, viscosity, and drying time. Accelerated test done in climatic chamber (37 °C, 75% RH) for one month supposed to check the stability of pH, viscosity, and drying time?Evaluation?s result showed us that F9 can be applied well, has pH 7,1±0,08, viscosity 227,84±23,66 cp, and drying time 12,43±3,23 minutes.
