The present inventors found that phenol compound degradation caused by reactions other than an oxidation reaction, which was considered heretofore to occur at 200°C or higher, occurs at comparatively lower temperatures. Provided is a method for preventing such phenol compound degradation and maintaining composition quality. Also provided is a phenol-compound-containing composition which has improved composition stability, and which suppresses quality loss caused by reduced phenol compound function, deepened color, and increased volatile content. The present invention is a phenol-compound-containing composition including a phenol compound and a polymer, wherein the free acid amount or the free base amount per 1 g of composition is less than 1×10-6 mol/g. |
