A process of preparing precipitated silica is disclosed. Said process comprises of reacting an aqueous solution of a metal silicate with a mineral acid in the presence of a surfactant solution comprising gelatin and C8-C20 sulfosuccinate blend, at a reaction tem-perature in a range of about 70 to 100 ºC with constant stirring such that a reaction mixture having a pH of about 10 + 0.3 is obtained optionally, allowing the reaction mixture to age at a temperature in a range of about 70 to 100 °C for a time period in range of 10 to 100 minutes adjusting the pH of the reaction mixture to about 4, followed by aging said mix-ture at a temperature in a range of about 70 to 100 ºC for a time period in a range of 10 minutes to 2 hours and recovering the precipitated silica from the reaction mixture.
