Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyol composition which can improve scorch resistance while preventing discoloration to pink and a polyurethane foam using the polyol composition. SOLUTION: A polyol composition which has a hydroxyl value of 5 to 1,000 KOH mg/g and comprises a polyol having an average number of functional groups of 1.5 to 8.0, an antioxidant having a plurality of metilox skeletons, an antioxidant having one metilox skeleton, and an amine based antioxidant is prepared, and the polyol composition and a polyisocyanate are reacted and foamed in the presence of a blowing agent to obtain the polyurethane foam.
