Abstract: A transparentization agent composition is a mixture containing 100 parts by mass of a dibenzylidene sorbitol compound represented by a general formula (I) having a particle diameter such that d97 is from 30 μm to 200 μm and 5 to 200 parts by mass of tetrakis[3(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl]methane, wherein the total for the two components is 50% by mass or more of the mixture. Also disclosed is a method for producing a polypropylene resin composition, including obtaining a polypropylene resin composition in which a dibenzylidene sorbitol compound represented by a general formula (I) having a particle diameter such that d97 is from 30 μm to 200 μm is incorporated in a polypropylene resin, by kneading a mixture containing 100 parts by mass of the polypropylene resin and 0.05 to 2 parts by mass of the dibenzylidene sorbitol compound by using a biaxial extruder at an extrusion temperature of from 220 to 250° C.
