PROBLEM TO BE SOLVED: To provide a quaternary ammonium salt with a function to give flexibility to hair.
SOLUTION: There is provided a quaternary ammonium salt represented by general formula (I), wherein R1and R2denote each a 4-34C linear alkyl group and may be the same or different to each other; R3, R4, and R5denote each a 1-3C alkyl group and may be the same or different to each other; X denotes a halogen atom; m is an integer of 0-3; and n is an integer of 1-10. Preferably, in the above quaternary ammonium salt, m is 1 and n is 3 or 4. Preferably, in the above quaternary ammonium salt, the difference in the carbon number between R1and R2is 2.
