A fiber softening composition having low-temperature activity is provided to allow easy application and supporting on a sheet, and to realize excellent solubility and dispersibility in cold water. A fiber softening composition having low-temperature activity comprises: at least one cation surfactant represented by the following formula 1, 2 or 3; and an emulsifier having a HLB value of 2-18. In the formulae, each of R1, R2, R5, R6 and R7 is a linear or branched C7-C21 alkyl, C7-C21 alkenyl or C7-C21 alkynyl; each of R3 and R4 is a C1-C4 alkyl; A is a C1-C4 alkyl, (CH2)nOH or (CH2)mOCOR8; B is (CH2)nOH or (CH2)mOCOR9, wherein each of n and m is an integer of 1-4, and each of R8 and R9 is a linear or branched C7-C21 alkyl, C7-C21 alkenyl or C7-C21 alkynyl; and X is a halogen atom or C1-C4 alkyl sulfate. |
