Abstract

Provided are a polyol composition in which hard caking does not occur when stored for a long period of time, and a polyurethane foam using the same. The polyol composition comprises a polyol compound, a foaming agent, a filler, and a metal oxide fine particle, the foaming agent including a hydrofluoroolefin, and the metal oxide fine particle having a count number ratio of OH ions of a metal constituting the metal oxide fine particle with respect to a total count number of all ions measured using time-of-flight secondary ion mass spectrometry of 0.1 or less.
