Abstract
Low foaming scouring agents (LSSA) were prepared by blending of amine salt of dodecylbenzene sulfone, poly (PO-b-EO) glycol, Newpol PP-2000, MJU-100, ethylene glycol and organic solvent. As the results of several tests, LSSA-2 showed good scouring effect, penetrating ability and emulsifiability, and showed not much water pollution. The foaming power of LSSA-2 measured by Ross & Miles method was 11mm foam height immediately after foaming. And the foaming power of LSSA-2 measured by Ross & Clark method were less than 310mm foam height at $30^{\circ}C$, 17mm at $80^{\circ}C$. As a result, LSSA-2 was proved as a good foaming scouring agent.
