A novel colloid active component, a method for manufacturing colloid aluminum silica gel, and a surfactant containing the same are disclosed, wherein the method includes the steps of: (a) dissolving a mixture of aluminum oxide, silicic acid, potassium, iron oxide, sulfuric acid and water into sulfuric acid; (b) adding potassium sulfate solution into the solution, and stirring at a low temperature to produce compositions with soluble aluminum double salt; (c) purifying the compositions to obtain a very pure and dense aluminum potassium sulfate; (d) adding aluminum silicate and water to produce alkali metal polysilicate-sulfate water salt chelate; (e) polymerizing and precipitating the resultant; (f) adding Mgo, Fe₂O₃, Ca(OH)₂, NaOH, KOH, and distilled water; (g) purifying and drying the chelate; (h) mixing the resulting microsphere, with sulfuric acid; (i) further treating the mixture and performing vapor treatment to obtain aluminum silicate molecular sieve; and, (j) polymerizing the aluminum silicate molecular sieves to a highly dense heel.
