Abstract: Provided are: a resin additive composition containing a specific metal phosphate, which composition has excellent dispersibility in a resin even when made into a pellet form and exhibits a desired physical property improving effect when incorporated into a resin; and a synthetic resin composition using the same. The resin additive composition contains, with respect to 100 parts by mass of (A) sodium-2,2′-methylene-bis(4,6-di-tert-butylphenyl)phosphate: 25 to 400 parts by mass of (B) a lithium phosphate compound represented by the following Formula (1); and 10 to 300 parts by mass of (C) a fatty acid metal salt represented by the following Formula (2). The component (C) is incorporated in an amount of 10 parts by mass to 50 parts by mass with respect to a total of 100 parts by mass of the components (A) and (B).

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.
