PROBLEM TO BE SOLVED: To provide a polyol component useful for producing a polyurethane elastomer which contains a large amount of an inexpensive polyoxypropylene polyol having a low monool content, and excels in processability and physical properties. SOLUTION: The polyol composition has a number average molecular weight of about 1,000 to about 3,000 Da, and comprises (1) at least 60 wt.% polyoxypropylene polyol having a low monool content, a number average molecular weight of about 2,000 to 12,000 Da, and a degree of unsaturation of <0.02 meq/g and (2)≤40 wt.% polyol having a number average molecular weight of about 400 to about 1,000 Da and a polydispersity of >1.1.
