Stage: PROBLEM TO BE SOLVED: To provide a polyol-containing composition that can prevent deterioration of catalytic activity while improving stability even when using hydrofluoroolefin as a foaming agent and can inhibit peeling caused between an object to be sprayed and polyurethane foam even when performing spraying construction under low temperature and to provide polyurethane foam using the polyol-containing composition.SOLUTION: The polyol-containing composition is used for producing polyurethane foam by reacting with polyisocyanate and contains polyol, a carboxylic acid ammonium salt represented by the general formula (1) as given below, a heterocyclic compound having a nitrogen atom, hydrofluoroolefin and a foam stabilizer. (In the general formula (1), R1 and R2 each independently represent an alkyl group; R3 represents a hydrogen atom or an alkyl group; and M+ represents a quaternary ammonium ion.)SELECTED DRAWING: None (Grant)
