| Abstract: | The unsulfated matter was determined with a set of ion exchange columns,a differential refractometer and a suitable mobile phase.The relative average deviation and precision were 4.0% and 0 6% respectively.This method was feasible for determination of the unsulfated matter in fatty alcohol sulfates,fatty alcohol ether sulfates and alkylbenzenesulfonic acids. |
