The Effect of Mixing Ratio on the Detergency of the Mixture of Nonionic and Anionic Surfactant

Abstract

In this report authors investigated the detergency of nonionic surfactant (polyoxyethylene nonyl phenyl ether, EO 10 mol) blended with anionic surfactant (sodium dodecyl benzene sulfonate). As a result, the detergency becomes lower by blending and steeply falls down to minimum by blending a small definit amount of anionics to nonionics, also minimizing in dispersing power and maximizing in surface tension.It is considered that some change in micelle structure of nonionics might have occurred by blending to affect detergency.
