In addition to soap and sulfonated oil, the main components of anionic softeners are cationic compounds or anionic and non-ionic compounds with long alkane such as octadecyl succinate sodium sulfonate and octadecyl sulfate. Generally has good wettability and thermal stability, can be used with fluorescent whitening agent in the same bath, can be used as special white fabric softener. It is also suitable for cellulose fiber, which can give the fabric better water absorption, but its absorption of fiber is similar to direct dye, which is weak, so the softness effect is poor, and easy to be washed away. In addition, because it has a softening effect in the bath, can be used for silk scouring, to prevent bruising (ash injury).
