The present invention relates to a process for the preparation of a cationic surfactant and a fiber softening composition comprising it and more particularly to a process for preparing a cationic surfactant comprising reacting a fatty acid and an amine, tertiarizing it and quaterizing with neutralization and a fiber softening composition using it. Also, the invention provides a process for preparing a cationic surfactant comprising the steps of reacting a fatty acid and an amine, tertiarizing it and quaternarizing it with dimethylsulfate or alkylhalide, and a fiber softening composition comprising it. The cationic surfactants prepared according to the methods of the present invention are excellent in solubility in water by possessing an amine group or hydroxyl group, which is hydrophilic, within molecules and have highly excellent physicochemical performances such as softening properties, anti-electrostratic properties, dispersion properties, etc, and accordingly they can provide a fiber softening composition having good softening effects to clothes and anti-electrostatic effects as well as having excellent dispersion in water and bio-degradable effects.
