A granular composition is provided to ensure excellent hardness, to be rapidly dissolved in a hydrocarbon solvent, and to be used as a stabilizer of a thermoplastic polymer. A granular composition comprises an organic compound with a melting point of 30-100 ‹C and a compound represented by chemical formula (1). In chemical formula (1), R^1 and R^2 are independently hydrogen atom, C1-8 alkyl group, or C5-8 cycloalkyl group; R^3 is hydrogen atom or C1-8 alkyl group; and X is a single bond, oxygen atom, C1-8 alkylidene group or C5-8 cycloalkylidene group.
