Surfactant in which the cation part generated by ionization in an aqueous solution exhibits surface activity.

Since the clothes are mostly made of chemical fibers, static electricity can be occurs due to friction on the surface of fiber. Fabric softeners are used to prevent this static electricity and improve softness feeling by neutralizing anionic fiber state with absorbing cationic surfactant. And it is also used for the purpose of disinfection with its sterilization function.

Due to the advantages of having affinity to all types of fibers, cation surfactants are being used in diversified ways. Most of household softeners are easily dissolved in water and adsorbed to fibers so that good effects can be performed even with a small amount. Also, cation surfactants have good durability compared with other surfactants, and excellent soft feeling.They also have advantages where sterilization and disinfection actions are excellent due to powerful adsorption of bacteria and occurrence of static electricity is suppressed.
