The water-soluble softening agent is a urea derivative having the chemical structural formula R1,R2-N-CO-N-R3,R4 (R1 to R4 are each H or a C1-4 saturated and/or unsaturated hydrocarbon group) and/or a water-soluble polyhydric alcohol having 3-15 carbon atoms. The number of carbon atoms and the number of hydroxyl (OH) groups in the molecular structure are such that the number of hydroxyl groups < the number of carbon atoms.
