Abstract

Waste cooking oil(WCO) is a good candidate as a material to make soap. It is typically cheaper than other oils. In this study, we have investigated the operation of produced soap from waste cooking oil. Phosphoric acid-hydration was provided for WCO degumming. The operating temperatures is 60°C, phosphoric acid concentration is 2% and 4% content of moisture is the optimum technology of degumming. The most favorable decoloring agent is activated clay, WCO and activated clay ratio of 100:5 at 70°C with 30 min treated time. The optimal technology of saponification is that the mass ratio of NaOH and WCO is 0.3:1, saponification temperature is 100°C and the concentration of NaOH is 30%.
